Brake squeel/Grind

I just bought new slotted and dimpled rotors and red stuff EBC brake pads and the rotors are from EBC as well. Ever since they were put on they have been squeeling/ grinding and even after i took them back to the mechanic who put them on he cant find anything wrong with them. Any ideas what the sound could be? And the sound only happens under light brake pressure.

Did you bed the pads in?

are the springs on the calipers that hold the brake pads slighly away, attached to the pads correctly?

I used to have a Honda Pilot and put EBC pads on it. They made all sorts of noise and I have steered clear of theri pads since. Since I have only had these on one vehicle I cannot say for sure they are all like this, but once was enough.

How hard would it be to check that?

There isn't a "spring on the calipers that hold the brake pads slighly away". There are a pair of "Pad Retainers", basically these metal clips, for each caliper that hold your pads in place. Aside from the caliper piston, nothing pushes the pads in or out. Just the piston pushing the pads into the rotors when you step on the brake pedal.



I doubt this is the issue though. EBC reds are known to squeal when cold. Are you only hearing this squealing when you first drive your car? Or do you hear it on the highway too?

If you want to be certain that it's not some other issue, just take off your wheels and just look at the rotors. Aside from the pads themselves, is anything else making contact with the rotors? For example, on the rear rotors, sometimes a rock or debris can get stuck between the rotors and the dust shield.

It happens all the time. It sounded like the noise was only coming from the front so we took off the wheels and checked the front brakes however we didnt check the back so i will do that.

At the same time i put new brakes on my car i also fixed a broken axle brearing and today i started hearing a squeel coming from my car at around 10-45mph any ideas what that could be? Im really starting to hate my G ive had it for 4 months and have been forced to put over $2300 into it

Yes the springs on the retainers are springs.. The pad retainers allow the pads to slide in and out on the caliper, but the springs on each retainer do actually pull the pad away from the rotor, maybe slightly, but they do..

The "springs" I am talking about hook into the loop on each front brake pad. Now I doubt these are why your brakes are squeaking like crazy, but when I did my pads last fall they would squeak when I backed up in the morning, and occasionally other times. That was because I didn't know to hook those into the loop on each pad. I did that a couple weeks ago, took 10 mins per side, and now they never squeak anymore

ahhh ok gotcha. Your use of the word spring threw me off. The "spring" and loop that you are talking about is the pad return lever:



Good call on that not being installed correctly. Maybe that's what Alex did wrong also.

Alright my brakes are still making noise and in my opinion its gotton worse but my dad wont let me do anything about it because hes to stubborn to even think that something might be wrong. He says i have loud car and all brake sound like this.

Could i just play it safe and go back to oem pads to eliminate all the noise or is there a possibility they could squeel too?
