Top 10 R1 Concepts Review With Brake Pads & Calipers

Imagine cruising a broad highway and enjoying breezy weather while riding your car. Excuse us for the next depiction, but suddenly another vehicle comes in front of you out of nowhere. You can imagine the rest, and we certainly do not want that to happen.

And you must be thinking you are safe because you have proper brake systems. But with the advancement of motor vehicles, it has become necessary to include other safety features.

This R1 Concepts review will clarify why and what kind of brake pads and rotors you will need and why it is necessary to maintain them regularly. Because over time, the pads lose their capability, and someone needs to replace and repair those parts. 

Brief Overview of the Importance of Brake Pads and Calipers in a Vehicle's Performance

Brake pads and calipers: they may not be the most exciting parts of your vehicle, but they play a crucial role in keeping you safe on the road. Without properly functioning brake pads and calipers, you might as well be driving a giant, metal death trap.

But let's not get too dramatic – let's take a closer look at the importance of these components.

First off, let's define our terms. Brake pads are the flat, rectangular pieces of friction material that press against the brake rotors (those spinning disks behind your wheels) to slow down or stop your vehicle. Calipers, on the other hand, are the clamping mechanism that holds the brake pads against the rotors.

Now, on to the fun stuff. When you hit the brake pedal, hydraulic fluid is sent from the master cylinder to the calipers, causing them to clamp down on the brake pads. The brake pads then press against the rotors, creating friction that slows down the vehicle.

But here's where things get interesting – the heat generated from this friction can reach up to 1,000 degrees Fahrenheit. That's hot enough to melt aluminum, which is why your brake pads and rotors are made of more heat-resistant materials like iron or ceramic.

So, what happens if your brake pads are worn out or your calipers are malfunctioning? Well, for starters, it will take you longer to stop – not exactly ideal when you're trying to avoid a collision. Worn out brake pads can also cause damage to the rotors, leading to even more costly repairs down the line.

But it's not just about the money, folks. Your brakes are a vital safety feature, and ignoring their maintenance can have serious consequences. So, next time you're tempted to skip that brake pad change or brush off that weird noise coming from your calipers, remember – it's not worth risking your life (or the lives of others) to save a few bucks.

Our Top 10 Picks for the R1 Concepts Review

While entering the realm of tires and vehicles, you will be baffled by the technicalities. There are so many factors you need to consider before buying each part. However, to save you from the trouble of digging through multiple rotor reviews, we have gathered some R1 Concepts rotor and pads that you might want to check out.
So, if you want to know if these are any good, then keep reading.

1. R1 Concepts CEDS10731 Rotors And Ceramic Pads

R1 Concepts CEDS10731 Eline Series Cross-Drilled Slotted Rotors And Ceramic Pads Kit - Front and Rear

When it comes to driving, bike riders need to be wary of the weather. The condition of the roads and pitch can .really affect the ride. So, if it rains in a particular area and the streets are always wet, then the CEDS10731 Eline series should be a good fit.

This rotor is suitable for wetlands as it is cross-drilled. So, it has drills running spirally across the body. The moderately sized holes are there for a reason. The holes allow the water to escape from the surface quickly. Hence, it exits through the holes and helps the brake perform well.

Also, this feature drastically improves the initial impact while in wet places. There are eight stacks of four holes on one rotor, and it is attached to the vehicle body through separate holes. You will get four brake rotors with specialization for the front tire and rear tire. The brand also allows eight ceramic brake pads.

These rotors are zinc-coated, which prevents internal rust formation and also helps debris slide off the rotor. Hence, gunk does not accumulate much in the corners, and you can get a better grip while brakes. The primary material is carbon alloy, which makes the rotors durable. These rotors also have diamond slots to indicate rotor wear.

Things I like

  • An affordable kit
  • Carbon alloy rotors
  • Suitable for rainy weather
  • Ceramic, long-lasting brake pads
  • Cross-drilled for better brake bite

Things I don't like

  • Gas removal is an issue

R1 Concepts CEDS11191 Eline Series Cross-Drilled Slotted Rotors And Ceramic Pads Kit - Front and Rear

This brand has several models that feature the cross-drilled rotors. However, each model has some tweaks here and there. These adjustments will help the user get the most out of their tools.

Moreover, this rotor belongs to the cross-drilled section of the Eline series. R1 Concepts came out with this specific series to let the people have more options. They wanted to create value at an affordable range. However, this kit can easily compete with higher-end brake kits.

You can use this kit for a car or a jeep as it comes with four rotors. The manufacturers specifically designed two of them for the rear end. The modification will help the user identify better, and that will reduce the chances of accidents. The pads are ceramic. So, it is smooth, and water will not seep into the chamber and create a damp environment.

All the products of the Eline series are made of carbon alloy, which provides superior strength. Thus, the rotor can handle the hardest of brakes. The designers finely tuned the model for brake surface finish, and the body also has a dual disc grind system. Double discs act as a safety measure against friction.

3. R1Concepts KEDS11317 Rotors And Ceramic Pads

 R1Concepts KEDS11317 Eline Series Cross-Drilled Slotted Rotors And Ceramic Pads

The more, the merrier - we all know that. But ‘more’ also means expensive. Hence, to make safety even more viable, R1 Concepts came out with the KEDS11317 model. This model is of the Eline series.

And the reason this set is more affordable than the rest is that it offers four rotors and only four brake pads. Even though the number of brake pads is less, it is still a good deal. The four rotors are useful, too, as they are designated for front and rear tires. So, you cannot randomly place them. You will have to maintain order.

Also, the rotors are cross-drilled, and they are excellent for times when the engine heats up because the drilled bits and circular holes provide space to escape. The item is also double molded and has an area in between for the heat to dissipate. And the reduction of temperature increases the initial brake bite and makes the action more smooth.

It also increases the probability of sudden break success. The carbon alloy also helps in keeping the rotors cold. Carbon creates a strong bond, while the alloy material adds heat-resistant qualities. Like other models from the Eline series, the KEDS11317 also has diamond slots that indicate where the rotor will fit.

Things I like

  • Heat dissipation facility
  • Diamond slots
  • User-friendly
  • Four rotors and four brake pads
  • Cross-drilled design

Things I don't like

  • The braking pads might create dust

4. R1 Concepts CEDS10926 Eline Series 

R1 Concepts CEDS10926 Eline Series Cross-Drilled Slotted Rotors And Ceramic Pads Kit - Front and Rear

Vehicle parts are notorious for wearing down. Rightly so, cause they go through a lot for making the car or bike move. However, you still want certain parts, especially braking parts, to be top-notch. Otherwise, accidents are inevitable.

That is why R1 Concepts’ premium rotors are demandable. This brand manufactures rotors with carbon alloy material, and it also has superior silver zinc coating. Silver zinc is known for resisting molds and rust. Consequently, the covering will wear off, but the rotor will still work perfectly fine.

Another benefit of silver coating is its ability to reflect light. As a result, the rotor does not attract extra heat. The cross-drilled aspect of the rotor also helps in this action. And the steam produced from the engine can quickly leave the space through the holes. These holes are drilled with precision so that the steam does not stay trapped.

Thus, the inside chamber stays moderately cold, and the engine performs better. The ceramic brake pads absorb an immense amount of heat to allow a smoother brake. When you push on the pedal, these pads take the initial temperature and protects the rotors. The ceramic model helps the pads sustain their strength.

Things I like

  • Increased brake pads bite
  • Diamond slotted
  • Smoother braking action
  • Ceramic pads
  • Kit containing brake pads and rotors
  • Cross-drilled model

Things I don't like

  • The rotor squeaks after some period

5. R1 Concepts KEOE11057 Replacement Rotors And  Pads 

R1 Concepts KEOE11057 Eline Series Replacement Rotors And Ceramic Pads Kit - Front

All cars and jeeps come with rotors placed at the rear tire. So, if you buy a new car, you will get brand new rear rotors. However, you will not get any front rotor in a brand new car. The good news is you can separately purchase front rotors.

You obviously would not want to discard perfectly good rear rotors, but you still need front rotors for maximum safety. So, to save your wallet, R1 Concepts manufactured the KEOE11057 model, which only offers front rotors. The price is adjusted accordingly, plus you get four braking pads.

These rotors are blank, meaning the surface is smooth. This kind is excellent for daily use as it provides a lot of friction surface area. Hence, the brake pads can clamp down easily, creating a smooth motion. The rotors do not have any slots or drills, but it has a double-disc grind mechanism. This system helps in quieter and smoother performance.

With double disc grind, you will no longer face uneven brake pads bed-in. Like other R1 Concepts rotors, this model is also silver zinc-plated, and the pads are ceramic. It is a superb combination of effective braking.

As most factory default rotors are blank rotors, these will fit perfectly without any modification. So, you will not have to wonder about repair stores.

Things I like

  • Smooth surface for stronger impact
  • Wider friction area
  • Two rotors and two brake pads
  • Easy clamping down
  • Even brake pads

Things I don't like

  • Tends to heat up

6. R1 Concepts KEDS12051 Rotors And Ceramic Pads

R1 Concepts KEDS12051 Eline Series Cross-Drilled Slotted Rotors And Ceramic Pads Kit - Front

A crucial aspect of the brake system is that it holds its shape over time. The smallest of cracks can create a big problem in the overall performance. Hence, you need an item that will assure you.

The KEDS12051 is an excellent choice as it has features to counter the cracking problem. Often, cheap quality pad and rotors break under pressure. But the R1 Concepts rotors from the Eline series has a countersunk system that reduces the chances of cracking by handling heat pressure.

Moreover, the heat effectively dissipates through the vane counts. The number of vane counts is also increased as a modification. This cross-drilled surface has holes at a precise distance. This precision helps the water to leave the rotor and the tire system. As a result, water cannot accumulate and create a disturbance.

Also, the rotors are designed for the front tires only. Hence, you will get a premium quality rotor and four brake pads with the purchase. The two items are compatible. Therefore, the pads can easily absorb the initial shock and still perform well.

Things I like

  • Countersunk mechanism
  • Effective heat dissipation
  • Water escaping path
  • Ceramic pads
  • Carbon alloy material

Things I don't like

  • The kit does not have rotor for the rear end

7. R1 Concepts Semi-Met Series Brake Pad

R1 Concepts Semi-Met Series Brake Pad With Rubber Steel Rubber Shims

The rotor and the pads need help from an assortment of other items. One such product is a rubber shim. Many kits provide compatible rotors and pads, but you rarely find shims in a package. So, if you want suitable shims, consider purchasing from the semi-met series.

Shims are essential in the brake system. They act as a middle-man between the rotors and pads. The rubber compound is necessary for preventing the other two items from clanging. You need to install them in-between the rotor and the pad.

Also, the rubber acts as an insulation against the friction. It protects the rotor and absorbs some of the shocks. Alongside the rubber shims, you also get two brake pads. Like a general R1 Concepts pad, it is made of ceramic.

The ceramic pairs well with the rubber shims, and the duo deals with the initial shock of a brake motion. Then the rest is done by the rotors and the calipers. Without the brake pads, the rotors would quickly form a crack.

Things I like

  • A semi kit
  • Contains rubber shims and brake pads
  • Durable quality
  • Compatible products

Things I don't like

  • Only two brake pads available with the purchase

8. Front R1 Concepts Ceramic Pad

Previously a lot of manufacturing industries did not bother about machine parts that were harmful to the environment. Many materials that cause damage to the surroundings cause even more damage to personal health. It exists among rotors and brake pads, as well.

So, if you want your rotors to be environment-friendly, then go for R1 Concepts brake pads and rubber shims. These items are low on copper. Hence, they will not crumble on the touch of high pressure and fumes. Non-copper pads also tend to last for a long time.

The kit also includes rubber shims, which are imperative in the braking process. Without rubber shims, the rotor and pad would scratch against each other and eventually wear out. So, to prevent premature damage, the shims are used. The rubber shims do not create any asbestos. So, you can expose them to heat and pressure.

Moreover, the two items are straightforward to use. All you have to do is plug them to the pad, and it will do the rest. The ceramic pads are durable and crack-proof.

Things I like

  • Low copper constitution
  • 100% asbestos-free
  • Durable rubber shims
  • Versatile brake pads

Things I don't like

  • The kit does not include rotors

How to Choose The Best R1 Concepts

Rotors, brake pads, calipers are complicated terms for an average person. But if you have a motor vehicle, then its best to know beforehand about different parts. This knowledge will help you counter the person selling you, and you will also know which one would be most suitable for use.

Price Point

This factor will help you decide whether you want economy-grade or premium-grade rotors. Economy grade rotors and pads will work on DIY or garage-grade brake pads. The price point is drastically different than a premium grade, but it gets the job done. However, these will reduce the life span of higher quality pads.

If you want something of middle ground, then R1 Concepts brakes are an option. They offer quality at an affordable price. Other than that, there are also higher-end brands such as Bosch.


The material with which these parts are made is vital because the rotors and pads have to bear an immense amount of pressure for halting the large vehicle.
Usually, aluminum, stainless steel, and a different concoction of alloys are used to manufacture these items. The critical factor is strength and durability. And the user should also check if the material can resist heat.

Special coating such as silver-zinc coating will help against corrosion and increase the shelf life. So, if the area is humid and the chances of rust formation are high, then this coating should be present.


The rotors have different slots, and holes and each model serves a purpose. Manufacturers commonly use a blank rotor that has a smooth surface. This smooth surface helps in easy clamping.

For humid and hot places, a slotted rotor is useful as it lets cold air enter the surface and reduce core temperature. There is another kind of rotor called the cross-drilled. That one is suitable for wet places or where it frequently rains. The cross drills help the water to escape the rotor chamber.

Besides different shapes, there are also modifications that the user should check, such as double disc grinds, O.E specs, and diamond slots.

Brake Pads

The brake pads should always be compatible with the rotors. The misplacements will throw the balance off and cause for faulty brakes.

How to Install R1 Concept Rotors and Pads

Are you tired of your brake pads wearing out faster than your ex's patience? Ready to upgrade to some fancy new R1 concept rotors and pads? Well, lucky for you, it's a fairly simple process that even the most mechanically challenged among us can handle.

Step 1: Gather your tools. You'll need a jack and jack stands (or a lift, if you're feeling fancy), a lug wrench, a torque wrench, a wire brush, and some brake cleaner. Oh, and don't forget your new R1 rotors and pads – we wouldn't want you to make a trip to the auto parts store for nothing.

Step 2: Jack up your vehicle and remove the wheels. This is where the lug wrench comes in handy. Just remember to consult your owner's manual for the proper lug nut torque specification – you don't want those babies flying off while you're driving.

Step 3: Time for the fun part – removing the old rotors and pads. First, locate the caliper bolts and remove them with your lug wrench or a socket set. Then, gently pry the caliper off the rotor, taking care not to damage the brake hose. Once the caliper is off, you should be able to slide the old rotor off. Repeat this process on the other side of the vehicle.

Step 4: Clean up the new rotor mounting surface with a wire brush and brake cleaner. You want to make sure it's free of any dirt or debris that could affect the new rotor's performance.

Step 5: Time to install the new rotors. Slide them onto the hub and make sure they're seated properly.

Step 6: Now it's time to install the new pads. First, compress the caliper piston using a C-clamp or a brake caliper tool. Then, slide the new pads into place, making sure they're properly aligned with the caliper and rotor.

Step 7: Reassemble everything in the reverse order you took it apart. Don't forget to torque the caliper bolts to the proper specification, as listed in your owner's manual.

Step 8: Repeat the process on the other side of the vehicle.

Step 9: Take your newly upgraded ride out for a spin and test out those new R1 rotors and pads. You'll be stopping on a dime in no time (or at least close to it).

Now go forth and brake with confidence, knowing you've got some top-of-the-line components keeping you safe on the road.
