Seals in the first gens are square cut... not possible to install wrong. These are not "low drag calipers" like later models that retract pistons slightly.As mentioned above.. length of push rod
Where the rears adjusted with the cable (big nono) or with the adjusters inside?
Or the seals in the calipers installed correct? these also act as the 'return spring' for the pistons.
CorrectIf it were the legnth of the rod wouldn,t it have released them when I loosened the master cylinder?
not much else there that can go bad besides seals and piston.I have no emergancy brake cable so it cannot be that. The caliper seals look good. I am thinking it is the calipers.
When I open the bleeder valves fluid oozes out, so it must have constant pressure on them. The only thing I know to try is new calipers. Thanks
I'll vote for that!When u release the pressure do the calipers release?
If so then it is the master cylinder
It sure sounds like a hydraulic problem to me.If not something else is holding them in...and the only thing is calipers are not moving on the slides and the pistons are not returning...it is the seals correctly installed that pull the piston back.
yepIt sure sounds like a hydraulic problem to me.
they have a slight taper, which I did not know the 1st time on one caliper, and it is not hard to catch one when installing ....also found out the hard way . didnt use the copper lube stuff.Seals in the first gens are square cut... not possible to install wrong.
I am happy to say that I replaced the calipers and the brakes now work great. I beleive the old piston were froze in the position they were in. Once I removed the calipers the pistons would not move under the pressure of a large C-clamp. It is strange though they were both froze up. Thanks for all the help everyone gave me.
