Hey guys, I replaced my front brake calipers and hoses with rebuilt calipers within the last year and they are dragging again. I did all new balljoints/u joints/ brake pads/rotors/wheel bearings(upgraded to late 99) two weeks ago and drove the truck for a week and then it sat for a week in the rain and now it's hanging up again. The truck sits outside and sometimes sits for a month between me driving it. I have to take it apart to see what it is but last time I used rebuilt calipers from the parts store. If it is calipers again, does anyone run aftermarket upgrades? Any suggestions on keeping this from happening? Truck is an e99 with the late 99 brake/bearing swap.
UPDATE: so I took everything apart, slide pins were good, brake calipers were not locked up but the pistons would not depress unless I cracked the bleeders so it's something further up. I put it all back together to go for a drive and eventually the brakes start hanging up again. The peddle is soft at the top and then gets hard the rest of the way. I'm thinking it's either the master cylinder or brake booster. I found a very small amount of fluid on the Boot of the brake pedal rod on the inside of the cab, don't know if that's related or not. Ps it's all four brakes locking up.
UPDATE: see post 11 problem fixed (so far so good)
