Ok Here we go so I hear a grinding noise in the Brakes so I change the front and back pads out. Then I do the normal road test with no problems. I give the rig back to the wife and tell her to pay attention to the brakes.So she uses the rig for errands and say's one of the brakes is getting hot and the pedal seems to not come all the way back up. Well I go get a new right rear caliper and drum just to be safe and swap them out seeing as that was the one that was getting hot. All of the other brakes are fine. So after the install and proper bleeding of the brakes I road test the rig. Damn it if the same one gets hot again and the pedal still is not returning to the full up postion. So I go get a new master cylinder and put that on. Proper install and bleed and the damn thing still does it. Is there some other part to this brake system that is killing me ???? Another part that needs replaced ??? And the thing is it's only the rear passenger caliper that is affected. and I replaced that already fearing that it was sticking. HELP ME !!!!!

 

1. Are you sure the parking brake isn't what's hanging up?

2. How are the slides that the caliper rides on? Any rust, burrs, or gouges that could be preventing the caliper from sliding freely?

 

Along what alloro suggested could it be a bent or crimped brake hard line or hose, another thing to check.

 

@ allero the em-brake isn't the problem it's the pads that are not returning to the neutral postion. And I will have to pull the tire and check to see if the rails are suspect. Thanks.

 

@ big poppa I will check that with the tire off tomorrow too

Thanks

 

Hope you do get your problem worked out but I do have a question of your 97, I thought all expeditions had disc brakes front and rear. I also like seeing someone call an expedition a rig, I always heard tractor trailors/semi being called one.

 

Cool. You know, maybe a crimped line ain't allowing the caliper to release hence the dragging brake but I did have stuck caliper pins in my SD so let us know what you find, good luck, hope its simple.

 

@hodges710 they do but they hid the emergency brakes on the inside of the rear rotor. rig is a generic term I use for all my vehicles Beats writing expedition more than once

 

will do big poppa

 

I'm a Union tractor trailer driver so I get a kick out of those terms too, rigs, but its all good, lol... I guess if somebody drives say, a Honda Civic and drives a SD occasionally, its classified as a big rig..

 

The brake hose has a restriction!! replace it
