Causes of inconsistent wear of brake pads
When our vehicle travels tens of thousands of kilometers, we will check the use of the brake pads so that we can replace them immediately. But we will find that the same wheel has different wear levels of the inner and outer brake pads. How is this caused?
When the wear of the inner and outer brake pads is not much different, it is normal, but if the difference is large, you should pay attention to the driving condition of the vehicle. It is best to go to the repair shop to find a professional master for inspection.
This phenomenon occurs mainly because the upper and lower movable shafts of the brake caliper are rusted due to long-term non-maintenance, which directly causes only the piston to control the brake pads to work back and forth! As a result, the brake pads inside the piston wear out quickly, and the outer brake calipers do not work because of rust, so the outer wear is very light, just like the new ones, in this case, the brake pedal will feel very soft when you step on it, and the braking performance is not good. The best thing is to add butter to the two axles of the brake caliper after the vehicle has traveled 30,000 to 40,000 kilometers. Brake pads are the protectors of vehicles and people. We must not be careless.
There are also some reasons that the materials of the brake pads are different, and the wear of the brake pads of different materials will vary greatly, and not only the wear and tear, but also the friction coefficient will be different, so there is a potential safety hazard for the vehicle. When we replace it, we still have to replace it inside and outside at the same time. Eliminate unnecessary security risks.
