2001 Yukon Screeching Brakes

[lamordnt]

The brakes on my '01 Yukon start screeching/squeeling after about 3-5 minutes of driving. It only happens after the car has warmed up and only occurs when I am braking. It is happening on more than one brake as noise is coming from both sides of the vehicle.

I recently pulled all 4 tires off, took apart the brakes and cleaned them with brake cleaner and removed all the dust and dirt. I inspected the pads and they have a little over 3/8 of an inch left before the metal backing.

I am wondering if my rotors are warping when they heat up (not sure if that is possible). If so, would resurfacing the rotors do the trick or should I just pony up for 4 new rotors? Or am I way off and this could be the cause of something else?

The noise is driving me nuts and the wife is about to kill me if I don't fix it. Thanks for suggestions in advance!!!

swap pads....

Check Caliper bracket and guide pin....after awhile they get sticky and caliper get stuck.

Bigtime!
Also make shure your pads have not worn a groove in them.

The rear brakes on my 2k Yukon were squeeling a little so I decided to change the rotors and pads. now its squeeling worse than before. guy I work with said maybe the caliper brackets were warped so I just changed those and used a different anti-squeeling lube on the back of the pads. its still squeeling. only thing I haven't changed is the calipers. I got the 2 piston calipers. could they be bad? when I had them off for brake rotor/pad/bracket replacement the pistons seemed to move easily back into the caliper. anyone else having these problems?
