Everytime I go from park to any other gear in the mornings and release the brake I hear a grinding sound I guess from the brakes...caliper release? And is it dangerous? I've heard it's normal but it's very annoying. I don't hear it much after driving a while but still hear it at times. Advice???

 

is your truck a 4WD ?? sounds like IWE trying to dis-engauge...

 

^^^^^ could be due to low vacuum on start up leaks down while sitting.

 

No it's a 2wd I apologize. By the time I got to work this morning I couldn't hear it coming off the brake pedal when parked

 

Do you live in a high humidity area?

 

How far do you drive to work?
The calipers should release when you take your foot off the brakes.
After you drive, feel the wheels - if any are hot, the caliper will need to be rebuilt or replaced.
Dangerous? Could create enough heat to freeze up and ruin bearings, hub, etc.

 

wheels? or rotors? ever since I put new brakes in the front its been doing it but i think i can hear it from the rear and those still have life in them so I have no idea
