What Causes Squeaking After Replacing Brake Pads?
2 Answers
Squeaking after replacing brake pads can be caused by: 1. The brake pads being made of harder material; 2. Improper installation of the brake system. The method for replacing brake pads is: 1. Lift the car and remove the tire; 2. Unscrew the fixing bolts on the brake caliper and remove the brake caliper; 3. Remove the old brake pads and push back the brake caliper piston; 4. Clean the brake disc mounting bracket and install the new brake pads. Ways to determine if brake pads need replacement include: 1. The brake pad thickness is reduced to one-third of the original; 2. There is abnormal noise when lightly braking; 3. The braking response is sluggish, and the braking force is weakened.
I also encountered squeaking issues after changing the brake pads, which was quite worrying at first. New brake pads have a hard surface and need about 200 kilometers of driving to break in, after which the noise gradually disappears. However, if the sound is very sharp, it might be due to dust or oil stains on the brake disc not being cleaned properly during installation, causing uneven friction. Additionally, if the caliper doesn't fully retract or the pins aren't lubricated well, it can cause slight dragging and noise. In my case, the noise faded after a few days of driving, but a friend suggested that using low-quality brake pads makes this problem more likely. In short, don't worry too much; drive normally for a while and see. If the noise persists, take it to the shop to clean the dust or readjust the position. Don't overlook these small details for safe driving, and regular maintenance can save a lot of trouble.
