Question about rebuilding calipers
 

I have a caliper on the drivers side that i was told is sticked, and because of that, eating up brake pads and rotors. I was also told that the calipers should both be replaced at the same time. I guess what im wondering, is whether or not there's a way to rebuild a caliper, or if I just have to go and buy new ones (really expensive) Any thoughts?

You can rebuild calipers. The 4 pistion calipers are hard to do. You have to buy a rebuilt kit that includes new seals and gaskets. The bad thing is that when you get the pistions out of the caliper, if they are pitted you will have to throw the caliper away and buy a new one. If you have never done this before : #1 I would try to find a caliper from a wrecking yard so you can pratice #2 brakes are an important thing on a rig are you sure its worth it to save some cash? Just my 2cents.

How much are calipers in your area? Remanufactered or rebuilt instead of new.

I would replace both or rebuild at the same time. Are you sure its not a brake hose?

I definatly see your point on the safety issue of it, and i think it may be best to try for remanufactured or something. As far as the hoses go, it very well could be a hose. I looked to see if anything was pinched or bent, and i couldn't see anything like that, but i was thinking of switching over to stainless steel lines for the front, cause i imagine that rubber has been on there since the truck was built (91). Thanks for the ideas

I still don't know if some of the stainless brake hoses are D.O.T. approved. Just make sure you buy some that are. I would replace the hoses in pairs also. A hose is hard to tell if it goes bad sometimes,unless you see a crack in it. Brake Hoses have a warranty of 4 years.
Does you rig pull to one side when you apply the brakes? Is the pads worn more on one side of the rig than the other? A bad hose can let fluid to the caliper but not back out, the hose starts to come apart on the inside and can act as a one way valve.
Hope this helps you out and good luck. :D

Can't help you on the rebuild (never done it). However, I would check the pins that the brake pads slide on (2 per side). If these are rusted it can also keep the pads from properly retracting. These are easy to fix if they are the problem. Just remove em, sand down, lightly grease, and reinstall.
