Every morning for some time now, when I initially put my 2005 F150 in reverse, i get an awefull noise from the brakes and have to accelerate through the pads sticking. But as soon as i get out of the driveway everything is free. If i drive it to the store, when i come out of store, totally free no binding, no heat nothing. Just everytime i get in the truck for the first time of the day. I am unsure on what to fix. Dont seem like a hose, was maybe thinking rusty pins. The caliber works fine after i get it out of driveway. Never sticks any other time.
any thoughts?

 

Are they the original calipers?

How about the hoses?

Either/or could cause this issue.

Hoses can internally collapse causing very odd issues like this, and calipers with worn/bent/rusted parts can exhibit this issue.

 

I do not know if original. I bought the truck a few years back

 

I would do a full service on the brakes.

I would replace all hoses, flush system, and remove the slide pins and hardware and lube.

If that doesn't fix it or the slide pins have corrosion, new calipers are due. I generally replace calipers per axle, meaning both sides.

Sometimes even if there is no corrosion, the rubbers inside of the caliper where the slide pin goes can get expanded over time and use causing subsequent binding.

I wouldn't let this go -- you don't want a stuck caliper, worse yet, for it to heat up and discolor the rim, heat up bearings, or even worse cause a fire. Not to forget a nasty smell and horrible fuel mileage.

 

Could it be the parking brake?

 

I will tear the back brakes apart and see what i can find.
thanks for the input
