Re: 77 f250 brake trouble

you might have to replace the caliper(s), the piston(s) might be locked up.

Re: 77 f250 brake trouble

after posting that I noticed you said you replaced the seals, I guess you would have notice then whether or not the pistons were locked up and I'm sure they weren't in order for you to replace the seals, I don't know what it could be after looking at that, how does the brake pedal do? does it come back up?

Re: 77 f250 brake trouble

are the calipers free floating on the slides make sure you have the spring on the correct side of the wedge and antisize them so they move and try to push them back with a c clamp i have seen these piston go in crooket it will help them seat in
