sticky rear calipers

[za_killer]

since buying the car i haven't been to pleased with the breaking power...

changed discs and pads about 1+1/2 month ago (all around) and found out the rear calipers were kinda' stuck... took some solid 30 mins + some decent quantity of degrip spray to get them running again

about 2 months later (at the current moment) the break pedal had to much free movement so i adjusted this using the hard brake + handbrake maneuver. problem is: now i got a sticky caliper on the rear right... it's not killing me, but it would be a shame to waste my new Zimmerman disks and ATE pads on this... is there any way to work around this or could this eventually be the problem of a "non-bled" brake system ... ?

Had this on a mates car!

Push the rubber boot down around the seal and clean the rubbish away from the piston, then geese it up and wind in all the back in with a rear caliper tool and that should do the job!

The car i done had the same problem and after this has been fine

Might be worth getting a new seal kit and getting the caliper rebuilt.

If they are that bad perhaps but usally they arent, they just stick and normally just winding them all the way in will do the trick !

the winding has been done during the disk-and-pads change (about 2 months ago), piston has been cleaned and greased

it may be that there was actually to much dirt, dirt that's clogging the piston up again, so it's well worth a second cleaning

Do the handbrake levers return all the way to there stops?

[za_killer]

i don't think it's a problem of handbrake not returning to it's position or the small pistons gripping at certain positions. i helped the guy cleaning my calipers (would have done it myself if i had a garage and a winding tool ). took half an hour to degrip the central piston. will try another clean-up and if that fails... i'll go for the rebuild
