'03 Brake Calipers Sticking - Ford Forums

I just bought an '03 Explorer with 35,000 miles on it and three times already I've had a problem with the rear calipers not completely releasing. Both sides don't do it at the same time. The last time, it was the left side and I got it home and got it in the air. Opening the bleeder had no effect. Also, the "floating" hardware is not binding. Physically freeing it up works so it seems to be a sticking piston. But both sides? The vehicle was parked for a long period so I guess it's possible. My question: Does anybody know where I can get a rebuild kit ? I really don't want to have to buy both calipers. And the stock units use phenolic pistons. I'd like to go with metal. Any help is greatly appreciated. Thanks, Ted.

summitracing.com and performancecenter.com should carry parts to do a rebuild. If anything else the pistons in the caliper are sticking and will shortly seize. If it was my vehicle I'd douse the calipers with brake cleaner to try and remove any rust and see if that works as a temporary fix. Calipers aren't cheap, even if you install them yourself. If you decide to replace the calipers be sure to do a good brake fluid flush as it's almost certain that as the vehicle sat contaminants would undoubtedly be sitting at the end of each line.
