The front brake disc is a metal disc made of alloy steel and fixed to the wheel, which rotates with the wheel. When the vehicle is on the brakes, the brake caliper clamps the brake disc and uses the frictional force to slow down or stop. Generally, there are round holes on the brake disc, and its function is to reduce weight and increase friction.
How to replace the front brake disc?
How to tell if the front brake disc is damaged?
How to tell if the front brake disc needs to be replaced?
The first step is to remove the front brake disc and replace it with a new one. Then lift the car with a jack. Unscrew the rear brake disc screw with pliers. Then remove the front brake disc. Replaced with new parts, reassembled, and installed the front brake disc on the car. After that, disassemble the front brake, replace your parts, and then continue to assemble the brake caliper. After the brake caliper is assembled, install it on the car, and finally install the brake disc. After the brake disc is installed, the entire replacement work of the brake disc has been completed, put down the jack, and let the vehicle carry out a trial run.
If there is noise when you tap the brakes (it may also be the effect of the brake pads running in at the beginning of installation), the front brake disc must be replaced immediately. Because the limit marks on both sides of the brake pads have directly rubbed the brake disc, it proves that the brake pads have exceeded the limit.
In this case, when replacing the front brake disc, it is necessary to cooperate with the inspection of the brake disc. When this kind of sound occurs, the brake disc is often damaged and scratches appear. At this time, even replacing the new brake pads still cannot eliminate the sound. It is recommended Replace the brake disc in time.
In addition, some poor quality front brake discs have hard spots, which will also produce abnormal noises. Generally, the abnormal noises generated will disappear after a period of time.
Most brake disc products have wear indicators, which are 3 small dimples on the front brake disc. Use a vernier caliper to measure the depth of the pit is 1.5mm. That is to say, the total wear depth of both sides of the brake disc reaches 3mm, and we recommend replacing the front brake disc in time.
Of course not all brake discs have wear indicators. We can judge the approximate depth by touching the outer edge of the disk with our fingers. Generally speaking, if the total wear depth of both sides of the brake disc reaches 3mm, the brake disc should be replaced in time.
Testing is a crucial part of R&D and Winhere has rich experience in Dyno testing. Now Winhere is equipped with 9 dynamometers from LINK to conduct product verifications like strength, thermal performance and NVH for brake systems of passenger cars and commercial vehicles. Also, there is professional equipment for natural frequency and damping measurement, such as LMS, RTE, etc., which strongly support the product development and approval.
