F 250 Brakes

Ivan in Mich · Apr 7, 2013

I was having trouble with the brakes on my truck so Yesterday I put new pads on it and found the wheel that was hanging up. I ended up replacing all the calipers as the the pins were rusted. I took it for a short drive and everything was fine. I drove it last night about 5 miles and felt it hanging up again so I took it home and all 4 wheels are hanging up now. I checked to make sure that I got the correct parts and they were. I am now thinking the master cyl is bad. Am I right in thinking this or is there something else to look for. It is an F 250 2004 Super Duty

Did you replace the caliper brackets? When the pins are stuck 99% of the time the brackets are toast. When I do the brakes and I have a hanger I replace it all.

Like I said before,change the hoses that go to the calipers. They deteriorate on the inside and the fluid goes in to the calpier under pressure alright,but it won't come back out.

I did change the brackets. Would all four hoses go bad at the same time or if one was bad would it affect all the others?

Bleed the calipers. If they bleed and release My bet is a master cylinder that is either not retracting to clear the compensator port, or the cup is failing. Jim

I usually have to replace all of mine once a year. Not sure why they don't last. Other folks have lots of trouble with with water in the brake fluid rusting up calipers leading to seizing.

Anything I plan to keep a long time I replace the original Brake fluid with Silicone Fluid..
Silicone lubricates and will not draw moisture.

Beware..some "NEW" systems may not work with Silicine Brake Fluid..(Bummer)..

It depends on what you mean by "trouble". I have a '92 F150 that from day one(49 mi on the odometer), the rear brakes grabbed hard when they were cold. And I mean if you werent ready for it, it would send you through the windshield at slow speed. It still does it, but when they warm up after a few applications, they quit grabbing. I saw a tech bulletin that said it was due to moisture in the linings after sitting all night. As they warm up, the moisture goes away and they work normally. That's pretty consistent with what I have, but your problem may be different.

Are you getting an ABS warning light or has the ABS been disabled?
The ABS unit is where everything from the master cylinder gets distributed to the wheels. A bubble or other problem there can cause many issues. Sometimes takes hooking up to the computer and running a bleeding procedure to get the all the air out.
The Ford ABS pumps are also prone to failure if you pressed pushed the caliper pistons back without opening the bleeders. The dirty fluid from the old calipers stops up the tiny passages in the controller.

Pull the fuse on ABS and try again. Dave
