Fix Squeaky Brakes: Knowing the Causes—Part 2

One of the most common questions we hear from customers is whether or not it’s possible to fix squeaking brakes.

The answer is that it depends on what the underlying cause is.  A while back we talked about a few possibilities; here are a few other explanations:

1. At other times the problem is caused by loose brake pads, which are normally held in place by clips or springs.  When those fail, then the pads fail to press evenly against the rotors, causing a squeaking noise.

2. Some pads have a silicone compound on the rear that dampens noise and helps them to operate smoothly.  If this material isn’t in place, then squeaking brakes are frequently the result.

3. Brake pads are designed to make noises when they’re wearing dangerously thin; however, the sound is usually described as a “squeal” or “scraping” in such instances.  But if the noise you hear is especially loud or annoying, then worn pads might be the cause.

4. In other cases, the squealing noise might simply be due to the fact that your vehicle is designed to use semi-metallic pads, which sometimes make a squeaking noise as part of their normal operation.  If this is the case, then you may simply have to live with the noise.  In rare instances organic pads can be substituted for semi-metallic ones.  This may eliminate the squeaking, but can also reduce the ability of the brakes to stop your vehicle.

5. Sometimes, you don’t have to fix squeaky brakes because it’s not the brakes at all! Your car’s springs, shock absorbers, or even your trunk lid could be the culprit. Any of these squeaky areas could be fixed with lube or grease. We’d be happy to help you out if this is the case.
If you’ve noticed a squeaking sound when you step on your brakes, then have us check them out, just in case.  It’s better to be safe than sorry, especially when it comes to something that’s so important to your safety.  We hope to hear from you soon!
