Please Help with brakes Options

[RonnieJ]

I just removed my rear brake pads that where pretty much rusted to the pistons and rotors from two years of storage. The pistons where not moving. I got the pads out and when I tried to adjust the pistons with the adjuster screws I lost some fluid and the pistons tightened up on the rotors with no pads on. What do I do. It seems that when I try to adjust the pistons in and out I'm not getting any movement. I've never tried this before and it's very frustrating right now. Any help, suggestions or even a picture of how I'm supposed to tackle this would be very much appreciated. Exactly how do you use the adjusters? do I loosen the nut and then use the hex screw. As you can tell I'm totally lost. Thanks

First of all, they need to be rebuilt. Leaking fluid around the adjuster means that seal is shot. The seal is more than likely hard and flat by now. You can try some PB Blaster around that seal area. It is billed as a "seal conditioner" as well as a great penetrant. It may swell the seal slightly to solve the problem for a little while. However, you need a rebuild.

Do you have an air powered wrench? If so, you'll need to get a 4mm hex socket and turn them at high speed to get them to come in. So, outers, clockwise at a high rate of speed in quick bursts from an air wrench. For the inners; do the same but counter clockwise.

You may want to wedge a piece of wood in there and try by hand again. Use the wood as leverage on the pistons to help push them in while attempting to turn the adjusters.

All this speaks to the fact that these rear brakes need to be rebuilt.
