Hey guys my breaks have me puzzled, there making a grinding noise, but only sometimes and the bads are in good condition. Any idea's what could cause this?

 

Rusty rotors or cheap pads possibly?

remove the drums and make sure it isnt coming from the rear

 

Rotors are fine as well pads are not really cheap either. Sounds like it is from the front but i guess ill check the back too..

 

could be caliper or something.

 

Check your bearings?

 

No because i assumed they would do it even when not breaking..

 

mine did this and it was the drums. the POS self adjusting spring cable snapped inside the passenger side drum and was getting caught everytime i hit the brake

 

The guy i bought my truck wondered why there was a pad rattle in the truck whenever he tapped the brakes doing like 30. turns out he had snapped both self adjusting cables and the back brakes hadn't been moved in like 2k miles.

 

mine do this too, i was toldi needed to apply brake grease on the back of the pads to get them from vibrating i have yet to actually try this, but i plan to very soon as im do for the yearly brake changing lol

 

Let me know if this works for you...

 

Mine was wheel bearing only rattled when breaking

 

I would second the calipers. Could be loose...check the caliper bolt.

 

Have you tried spraying them with brake parts cleaner? Did that to mine and it stopped the little squeak that they had.

 

ik this is an old post my truck is doing this in the rear and its the ebrake cables

 

assuming it really was ur brakes josh, just because the rotors looked ok doesnt mean they were, could be warped, need to check with a micrometer. also check run out with a dial indicater, to those who said calipers, they are not very likely to fail. i would think it would be cheap pads or rotors. did u replace them before?
