Whinning noise when braking

Could this be a bad caliper?
I've checked for any leaks on the hoses, and they seem fine
It has a new brake booster
I checked my pads, and they are pretty messed up from one side...will update pics later

It sounds exactly the same as when a truck usually brakes and makes that long a$$ whinning noise. But this is only when braking slow

Check your anti-rattling clips on the calipers...

I did, still makes the same dumb sound...someone told me that it is wheel bearing? but if it were the wheel bearing then it should sound very differently? :o

No, bearings never whine when braking.
What does 'pretty messed up from one side' mean"
One pad worn more then the other because of a sticky piston or slide, or left to right side of the car?
Brake pad noise, try the goop that parts places sell, taper the pad, clean & smooth the pads backing plate where it contacts the caliper & those clips, piece of gasket paper/shoe box between the piston & pad.

I'd try putting a taper on the leading & trailing edge of those pads & see if that helps. Are you runnin drilled/slotted rotors miswuevos?

is the bottom one worn unevenly? looks like it, i bet the caliper slider thing is bent or frozen. when changing your brake pads, its a good idea to lube the bolts and stuff that allow the caliper to slide on the carrier.

konaTrueno723. No I am running solid discs :(

MisterJerk. I resent the calipers back to the company and told them they were defect, gladly they responded and told me it is going to take a week and half :x :x :x . I guess its worth the try,

I have tried lubing the bolts, put the shims, the clips, and nothing...


Will get back to you guys when I get them back :P
