Benefits of Shimano Hydraulic Disc Brake
Shimano has produced a variety of unique disc brake tech that has made the company product stand out. Some of its benefits are:
1. Long lasting
The major cause of brake failure occurs when pads and rotors become hot. However, Shimano has created an ice-technology which cools the brake system thus making it long lasting. When the pads and rotors get hot, the system transfers heat to all other brake parts; thereby improving cooling.
2. Easy Bleeding
Most Shimano Hydraulic disc brakes come pre-bled. However, self bleeding is also enhanced through the one-way bleeding system. It allows you to refill oil while removing bad oil and bubbles.
3. Presence of Center Lock Rotors
Shimano also has a lock ring that makes it easier to install and remove rotors. There is also the spine-based mounting system that helps enhance braking.
Other benefit are:
- Cost- effective.
- They are easy to install.
- They are easily adjustable.
- Highly compatible with any bike.

How to Align Brake Pads
When in use, brake pads tend to misalign. Causes of misalignment may be from crash or fall. When a brake pad has lost its effect, to ensure proper functionality and safety, one of the best things to do is to bring it to rest. Below are some of the necessary steps you need to engage in as you reset your Shimano brake pad.
- Place your bike on the repair stand and remove the pad retaining screw.
- With the use of a clean cloth, wipe the piston surface and inner caliper body. After that, using a plastic lever, push the piston into a caliper body and watch to see if the movement of the piston is as a result of excessive fluid.
- Install the pads as well as a floating shim
- Squeeze the lever on both sides to align with the wheel. Do not force the lever when fixing the wheel. However, use washers when aligning pads to the rotors. Additionally, use bolts to firm the process.
How to Maintain Disc Brake
If you use a hydraulic disc brake, then it is essential to carry out a routine inspection for efficient use. There may be effects such as leaks and holes in the hydraulic pipes. Also, dirt may tend to build up at these spots. However, we will be looking at various maintenance of the disc brakes.
Disc Brake Rotors
Check the rotors for clogs of dirt or debris and also ensure that they are straight and do not tend to rub on the brake pads. To clean dirty rotors, use alcohol and sandpaper and rub lightly on their surface. Also, check the state of the bolts to ensure that they are the right fit as loose bolts can result in parts that lead to producing noise when braking.
The brake lever can attract dirt over time or slip out of position. You can also check for leakage of hydraulic fluid near the lever. To check for leakage, during full engagement of the lever, squeeze the brakes. There should be at least 1inch space between the inside edge and the handlebar. Do not press the brake lever when the wheel is detached from the fork when using hydraulic brakes as it may cause the brake pads to clamp together, which can be challenging to remove.
For safety and better cycling experience, take the following brake, pads, and rotor care tips.
- Check pads and rotors regularly, especially in wet seasons.
- Do not touch rotors with bare fingers. Handle with oil.
- Do not use spray lubes on them
- Use the proper disc brake products or Isopropyl to clean them
- Always use spacers for brakes when wheels are detached.
Shimano Altus BR-M315 disc pad replacement
Shimano M315 Review (FAQs)
1. When should I replace the fluid in my brake?
The hydraulic disc brake is made up of a cable filled with hydraulic fluids. When the brake is activated, this fluid is pulled up by pressure into the caliper, causing it to press against the disc. Although Shimono’s manual has no defined period to change the fluid, it did indicate that fluids should be replaced when it becomes discolored.
2. Should I get hydraulic disc brakes?
Yes. Hydraulic brakes have a higher performance ability than the mechanical disc brakes. They are also more efficient as they require less pressure to get high braking power.
3. When should I change Shimano hydraulic disc brakes
The best time to change your Shimano hydraulic brake is when it has a faction or any surface development. Development can be in the form of bends, which results from excessive hotness or impacts from the crash. However, these changes can be slight but can be detected when rubbed against the brake pad when turning the wheel. The thickness of the brake is also an indicator that it should be changed. Measuring its thickness is through a micrometer or digital caliper.
4. What is bleeding?
Bleeding is a way of removing air from the hydraulic brake when air bubbles get into the pipes. The air in the brake system can lead to low brake performance as it results in inconsistency in the pressure system during hot periods. It can also lead to the inactiveness of the lever during hard brake application.
5. How often should I bleed my disc brake?
Bleeding of disc brakes depends on the frequency of usage and distance of ride. However, you can bleed your Shimano hydraulic disc brake every six months. It can be less mostly if you notice some signs on your brake. The most familiar sign is when you pull the lever down to the handlebar before the brake is activated.
6. What kind of oil does Shimano disc brake use?
Shimano has been producing brake fluids since the 1960s and 70s. They produce mineral oil for their brakes with a higher boiling point than other DOT fluids. Also, the quality and boiling point of their brake fluid has not changed because of their inability to absorb moisture.
7. What size of disc brake do I use?
The type of disc brake to use is dependent on the size of the wheel. For back wheel braking, 140mm is the minimum size. However, the 160mm disc will cause the back wheel to slide easily. But with this disc size, it may be challenging to get the bike to stand on edge, which is why most are built with 180mm disc at the front. Also, for the best brake power, a 200mm disc is recommended. Big disc tends to heat up and cool off in less time than the smaller ones.
Final Words & Recommendation
With these written words, whether you are in for a hydraulic disc brake purchase or a shifter, you are sure to get the best. This Shimano m315 review highlights the company's m315 since they are noted for quality with their effectiveness and ability to offer great products.
