Why do the brakes squeal after it rains?

The abnormal noise of the brakes after the rain is because the water splashed from the road adheres to the brake calipers and brake discs, and the water usually contains sand, dust and other impurities, which will produce abnormal noises when braking. You only need to step on the brake lightly to scrape it off.

　　

The braking system is one of the important parts of the vehicle, mainly to slow down the vehicle. Usually, the brake design of our family cars uses disc brakes, mainly including brake discs and brake calipers. The friction between the calipers and the brake discs can slow down the vehicle. However, during our daily driving, the caliper and the brake disc are separated, and the caliper will clamp the brake disc only after the brake pedal is stepped on, so some debris may stick to the brake disc or caliper during our driving. If the brake disc is unevenly worn or damaged, etc., it will cause abnormal noise when braking. At this time, we need to check the braking system of the vehicle in time, and clean or replace it to ensure our driving safety.
