Help with rear brakes, what am I doing wrong? Options

[Kevin@ojai.net]

So, a few minutes ago I tried replacing my rear brake pads with out success. I was unable to retract the pistons far enough into the calipers to fit the new pads in. All I did during my failed attempt was remove the old pads, then pry against the pistons. This process has worked for me on other vehicles, but I had almost no luck on the 914. I was able to retract the pistons a little, but not nearly enough to get the new pads installed. What am I forgetting to do? What am I doing wrong?

The outer adjuster only adjusts the outer piston. It had a plastic cap covering it. There is a jam nut to loosen, then the adjustment is made with the socket head screw (allen screw).

The inner piston adjuster is accessed through the hole in the trailing arm. (That's why that is there). The inner adjuster came with a socket head bolt as a cap. There was an improved part that was a hex head bolt cap. The adjuster is another socket head screw exactly like the outer adjuster except that the inner adjuster has no jam nut.

The adjusters are used to retract the pistons as well as to adjust the venting gap for the rear brake pads.

Good luck and read your manual.
