Caliper Piston......Gone!......WT....F!

[gowing82]

OK, so I hear a screaming noise from the truck????? No grinding at all in the pedal, I get the truck home pull the drivers rear brakes apart, the back pad is gone, metal is melting it's so hot, the caliper has too be pried off
once the caliper breaks free the piston is got little pieces falling out and about 1/2 of both pistons are gone Passenger side and fronts all still over 1/2 the life left on the pads. I changed the rotors and the pins that hold the parking brake pads on are laying in the bottom of the drum, they rusted right thru the backing plate I have done many......many brake jobs and have never seen the piston in a caliper gone.
Anyone else having this problem

had this exact same situation happen on my 2000 to me about a year ago. back passenger side blew up on me while driving down the road.

I seen it a lot in my highschool autoshop. That was mainly due to neglect and morons that dont take care of anything.

But in your case I would say something was wrong for sure.

Sticking calipers is all to common in these trucks. Sounds like that one stuck after braking and just burned itself up with heat.

When I was in the local Jeep club we were towing back from the off-road park and one of the guys with an F250 gasser had the same thing happen. No one realized it until he got it home made a helluva mess.
