    Default Need piston seal for drivers side calliper, 2.0 Astra mk3 brakes

    Does anyone know where I can get the calliper piston seal for the brakes off the 16v 2.0 mk3 Astra, I think they are ATE callipers but I'm not sure. I have a lovely redtop nova that I can't drive at the minute because my drivers side callipers won't retract, I don't really want to run it without the dust seal so I haven't yet removed the piston to clean it out, anyway any help would be much appreciated to source either a new seal or even a full calliper, thanks in advance for any help

    Yes GM sell a calliper kit and you get all the rubbers and the plastic caps that cover the slider bolts. Very reasonable price too

    Thanks for the help, I've been struggling to find out wat brakes are actually on it coz I can't make out any of the stamped numbers, does anyone have a full calliper for sale?

    Just buy a seal repair kit off ebay. See the part numbers thread for the correct kit number. I posted in there.

    They're over there with their new toys. Someone brought them in. No idea who bought them though.....

    If the piston is seized i'd say it's shagged. The seal don't just jam. Just get another caliper. post a pic of what you've got and we'll help you out.
