Brakes squeak / grind

3 noises your brakes should not make
Pay attention to the sounds of your car. If you start to hear unusual sounds, get your car to a trusted mechanic. The longer you wait, the more costly the repairs can become.

1. The high-pitched squeal that goes away when you apply the brakes
A squeal while you are simply driving down the road, and that goes away once you brake. That is a warning indicator that several manufacturers built into their product to give you a little bit of notice before you get into the brake rotors, so if you can catch it when it’s making that noise it tells you it’s time to do brakes. And generally, if you can get in before it progresses to the next stage of noise, you can get by for much cheaper than if you get into an actual grind of a rotor.

2. The grinding or a hard growl
What that usually means is that your pads have worn all the way through and they are grinding into the rotor itself. That is a much louder and abrasive noise. Generally, at that point you are going to be into more money. If you can catch it when you first hear it, you may be OK. If you put it off for a day or two, or three, then you are going to grind into the rotor. What usually occurs is that the caliber in the hydraulic part that controls the brake pads goes beyond the range that’s normally used to function in and over extend itself – which typically means you’ll have to replace the caliper as well. So, if you are into that situation where you’ve progressed from that squeaking noise to grinding, you probably just jumped from $150 to several hundreds of dollars.

3. Squeaking when you stop
This squeaking usually doesn’t mean you need a replacement, rather a poor installment the last time the brakes were put in. There are several contact points that you need to lubricate when you are putting in calipers and rotors. If those aren’t lubricated and/or the brakes weren’t installed properly, then that noise could simply be the pads and shoes moving.
