How To Replace A Motorcycle Brake Pad By Yourself

As we all know, the brake pad is the most crucial part in brake system. The effect of brake depends on the quality of the brake pads. Therefore, it is very necessary for us to check the condition of brake pads regularly to know whether to replace them.

 

 

When To Replace A Motorcycle Brake Pad?

 

The replacement time cycle of brake pads and discs is not fixed, which depends on the driving road conditions of the vehicle and the frequency and strength of the driver stepping on the brake pedal. Generally speaking, the service life of the front brake pad is 30000 ~ 50000 km, and the service life of the rear brake pad is 120000 ~ 150000 km. In addition, the brake pad from a reliable motorcycle brake pad supplier has longer sevice life. 

 

The following are several simple ways to check whether the brake pads need replacing.

 

1. Check whether the brake pad and brake disc become thinner. You can use a small flashlight for inspection. If the black friction material of the brake pad is rapidly worn out and the thickness is less than 5mm, it should be considered to replace it.
2. The second method depends on your experience. If you are a driver for many years, you may feel that whether the brake pads should be replaced or not.
3. The brake pads of some old vehicles are not connected to the driving computer, but a small iron plate for alarm is installed on the brake pads. When the friction material is worn away quickly, the brake disc will not wear the brake pad, but the small iron plate for alarm. At this time, the vehicle will make a harsh "chirp" sound of friction between metals, which is the signal of replacing the brake pads.

 

How To Replace A Motorcycle Brake Pad?

 

Well, we have known when to replace a new brake pad. We will teach you how to replace it at home by yourselves.

 

Find brake pad

 

Before replacing the brake pads, put down the handbrake, put the car up, and remove the tire. Then, you’ll see the brake pump on the brake disc, and the brake pads are inside the brake pump.

 

Remove the brake cylinder

 

Then start to remove the brake cylinder. Firstly, screwing down the fixing screw on the brake cylinder with a wrench. There is one fixing screw at the top and one fixing screw at the bottom. It takes two wrenches to screw the fixing screw. One wrench fixes the outer screw head, and the another wrench rotates the middle nut counterclockwise, so as to remove the screw. If the screw is too tight to turn, spray a little WD40 for lubrication.

 

After the two fixing screws are removed, we can remove the whole brake cylinder. However, a brake alarm line will be connected to the brake cylinder of some cars. If so, You need to remove the alarm line and then remove the brake cylinder. After the brake cylinder is removed, don't let it hang there. It's best to hold it with something, otherwise it's easy to tear the wire on the cylinder.

 

Remove the old brake pads

 

After removing the old brake pad and comparing it with the new brake pad, you will find that the old brake pad is obviously much thinner.

 

Jack back brake cylinder piston

 

The next step is to push back the piston in the brake cylinder. Because the new brake pad is thicker than the old brake pad, if the piston in the wheel cylinder is not pushed back, the wheel cylinder cannot clamp the new brake pad, which requires a piston jacking tool. Install the piston jacking tool into the slave cylinder, support the piston, and then turn the handle to Jack the piston back.

 

Install new brake pads

 

Then, install the new brake pads on the bracket. It is best to clean the mounting bracket of the brake disc before installation, because there is a lot of brake powder on the bracket, it is not easy to jam the brake pad, and noise may occur when stepping on the brake. Clean the brake cylinder and clamp the brake pads. If there is an alarm line, connect the alarm line. Finally, screw back the screws on the cylinder and the brake pads are installed. Then step on the brake several times with your foot until you can't step on it. This is to put the cylinder piston that has just been pushed back into position.

 

Running in new brake pads

 

The last thing to do is to run in the new brake pads. Driving the car to 80 or 90 kilometers per hour, then step on the brake slowly, come back several times, let the brake pads run in. 

 

Well, the replacement brake pads are finished. It is simple, right? CHONGQING KALIDA INDUSTRY CO., LTD is a reliable China motorcycle brake pad supplier, which provides OEM motorcycle brake pad.
