Red face brakes

I have a 2002 F150 king cab 4.6 XLT 53000 mi. when I try to stop I would hear a roaring,grinding noise so I checked the front pads. They needed replacing so I put new pads on, Raybestos QS couldn't turn the rotors because they had runout. After 2000 mi. the roaring noise returned so i returned the Raybestos QS pads. The next thing I did I bought NAPA TS pads,front rotors,bearings and seals I also replaced the rear pads with NAPA brand and turned the rear rotors,oh by the way I bought a bearing packer too. My problem is after 2000mi. more the roaring noise is back, not as bad but it's getting there. I've been replacing brakes on my cars for 20yrs and I've never had this problem. The truck is still under warranty. Could someone please help!!!!!!!!

Thanks,

Kennyh

Check your front tires for cupping. This will cause a roar that will get louder when braking. I don't have any other ideas, assuming your noise is coming from the front.

You say you didnt turn the rotors due to runout. Did you replace them? Or are the same rotors still on there?

He didn't do anything with them the first time but the second time he replaced the pads, front rotors, bearings and seals and he turned the rear rotors.

Describe the noise please.... Tire noise will not be grinding... roaring and thumping, but not grinding.

Rotate your tires front to rear and see if it changes.If it does it's your tires.

possibly, could be tires.


but how would the roaring noise disappear only when replacing the brakes, and return twice at 2000 mile intervals, and then needing brakes again?

i would be looking for a dragging caliper, seized caliper mount, misadjusted master cylinder, collapsed hose, or even contamination of the braking system.


were the pads metal to metal each time you inspected them??

why are you fixing it if it's under warranty?
