Squeeling brakes.

[AmericanRiceEater]

Hey i just replaced new rotors on both front brakes a long with both sets of pads. For the past two days they have been squeeling as bad as they were before i replaced them. I cleaned the rotors pretty good before i put em on. Should i give them another day to wear in ?

Well, IMHO two days is plenty of time to break in a set of pads. What pads did you use?

 

[matt5112]

did you lube anything?

Did you make sure the anti rattle clips were still there?

I used a cheap set of pads but they shouldnt be making noise theyre new. And i lubed up the old calipers and cleaned the new rotors pretty good. But do you think it could be the rattle clips ? its just pissin me off bc the rotors and pads r brand new and i replaced them so they wouldnt make noise. its got to be something easy to fix , i just havnt had the time to look

Check for:

Loose fitting brake in the caliper
Loose fitting or missing brake hardware (i.e. shims, anti-rattle clips)
Loose lug nuts or caliper hardware
Debris caught between the rotor and the surface of the brake pad
Heat cracked or worn rotors
Uneven finish on resurfaced rotors

Semi-metallic pads can sometimes cause noise because of the pad ingredients.
However in my experience “cheap” pads are usually on the soft side and cause very little noise.

Good luck.

I wonder if it could be that the rotors and pads are both brand new, maybe the rotors need more time to wear in than the pads?

Likely cheap pads didn't have shims on the back. If you didn't use something goopy/sticky like disc brake quiet to spray the back of the pads and stick them in place, that could do it. Or really cheap pads..

This is my guess. If the cheap pads don't have a damping pad on the back, you will need to apply some anti squeal compound to the back of the pads. Without the damping material, expect it to squeal like a pig.
