What Causes the Noise When Releasing the Brake Pedal?
2 Answers
Reasons for noise when releasing the brake pedal are as follows: If it is a squealing noise: First, check if the brake pads are worn out (the wear indicator is making noise). If the brake pads are new, check for any foreign objects caught between the brake disc and the brake pads. Uneven hardness of the brake disc or the presence of metals like copper can cause the brake pad surface to become uneven. If it is a dull noise: It is mostly due to issues with the brake caliper, such as worn guide pins or detached spring plates. If it is a hissing noise: If the hissing noise persists, check for brake drag. Poor caliper retraction can cause prolonged friction between the disc and the pad, leading to abnormal noise under certain conditions.
Last time my car had this issue too, making noise when releasing the brakes. It could be due to worn-out brake pads getting thinner, or debris like small stones stuck inside causing friction sounds upon release. Having driven for ten years, I've noticed humid weather can also cause rust, making the noise more frequent during morning starts. Another possible reason is the caliper not retracting properly with a stuck piston - this needs immediate inspection as prolonged driving could damage the brake disc. I recommend paying attention to braking habits; avoid sudden stops to extend lifespan. During regular maintenance, it's best to check the brake system, especially after high mileage. Personally, I inspect brake pad thickness every six months and replace them immediately if too thin - safety first. If the noise accompanies other abnormalities like car shaking or longer braking distance while driving, don't delay - visit a professional repair shop to eliminate risks.
