How to Bleed Your Surge Brakes in Five Easy Steps

Bleeding surge brakes (BSB) is a method of bleeding brake fluid from the master cylinder reservoir into the wheel cylinders to reduce or eliminate brake fade. This is done using a hand pump to force air through the system.

A BSB is a simple tool that allows you to bleed your brakes without having to remove them from the vehicle. It consists of a hand pump connected to a hose into the master cylinder reservoir. Once the pressure reaches a certain point, the brake fluid flows out of the reservoir and into the wheel cylinders.

This article shows you how to bleed your brakes and explains why it's important to do it regularly.

How to Bleed Surge Brakes

Bleeding surge brakes is important for proper operation. Here, we will show you how to bleed surge brakes.

Step 1: Locate the Brake Bleed Screw

The brake bleed screw is typically located on the underside of the bike near the brake pads. If you cannot find the bleed screw, you can try to remove the brake pads and bleed the brakes by using a vacuum cleaner or a syringe.

Step 2: Remove the Dust Cap

The dust cap on the surge brake should be removed in order to bleed the brakes. To remove the cover, start by removing the four screws that attach it to the frame.

Praise the cover gently off of the brake after removing the screws. The brake should now be bled. To do this, insert a syringe with the appropriate fluid and push it all the way into the brake line until the fluid comes out.

As you bleed the brakes, watch the level of brake fluid; if it gets too low, you may need to add more fluid.

Step 3: Place a Container Under the Screw

When bleeding your brakes, it is important to place a container under the screw to catch any fluid that may escape. As a result, the fluid will not get all over your car and could potentially cause damage.

Step 4: Open the Bleed Screw

The bleed screw is a small, Phillips head screw located on the caliper bracket. It is used to adjust the brake bleed rate.

To open the bleed screw, first remove the caliper bracket by unscrewing the two screws located on the bracket and the bracket itself.

After the bleed screw has been pried open, use a flat head screwdriver to pry it open. Make sure you don't strip the threads by overtightening the screw.

Step 5: Pump the brakes.

If you're bleeding your brakes, you'll need to pump them to get the fluid back into the system. To do this, use a standard brake pump or a bicycle pump. Pump the brakes until the fluid comes out in a steady stream.

Step 6: Close the Bleed Screw

In order to bleed the surge brakes, you will need to close the bleed screw. To do this, first locate the bleed screw on the wheel hub.

It will be a small, Phillips-head screw. Once you have located the bleed screw, use a flathead screwdriver to turn it counterclockwise until it becomes tight. Do not overtighten the bleed screw, as this may damage the hub of the wheel.

Step 7: Replace the Dust Cap

After bleeding the brakes, it is time to replace the dust cap. The dust cap must be removed by removing the four screws that hold it to the caliper.

Pull the dust cap off the caliper after removing the screws. Be careful not to damage the brake pads or rotors in the process. Replace the dust cap by re-attaching the screws and ensuring that it is properly secured.
