Why Does the Car Make Strange Noises When Braking?
2 Answers
Here are the specific reasons why a car makes strange noises when braking: 1. Improper installation of brake pads: When installing new brake pads, the old brake discs were not polished, resulting in a poor fit. A poor fit or installing new brake pads without polishing the old discs will cause the new pads to rub directly against the uneven surface of the old discs, ultimately leading to uneven wear of the new brake pads. 2. Brake system malfunction: There may be a defect in the brake system itself, causing the brake pads to only partially contact the brake discs. This increases the pressure per unit area on the brakes, resulting in strange noises. It is recommended to check components such as the caliper and guide pins. 3. Presence of foreign objects: Foreign objects cause a mismatch in the contact surface, leading to strange noises.
Over the years I've been driving on the road, I often hear squeaking or clicking noises when braking. This is mostly because the brake pads are severely worn or the brake disc surface is scratched, especially after rain when water accumulation leads to rust, causing increased noise. Sometimes small stones or dust get into the brake pads, creating noise during friction. In such cases, prompt cleaning will solve the problem, but don't ignore it. If left unattended, braking efficiency may decrease, increasing the risk of rear-end collisions. I recommend checking the brake pad thickness during every maintenance service and replacing them immediately if they're thin, to avoid spending more money repairing other components.
