4 pots.
 

Hi , the 2 outer pistons on the drivers side 4 pots seem to be stuck in , whats the best way to free them ?

youll have to pop them wright out and clean them with a very fine wet n dry till all the rust on the piston has gone and the same inside the caliper to help them go in i put a bit of copper grease on them it just helps to not damage the seals :ok:

IMO its a bad idea to use copper grease on brake seals/pistons..............it can react with the rubber, causes swelling and stiction (ooh err missus)

look for pukka hydraulic "red" grease..........

:agreed:

Just dip the piston in brake fluid to aid reinsertion if necessary:nod:

Copper grease will cause damage to your seals if you use it:nono:

Maybe a stupid question , but how do u pop the pistons out ? , will fluid go every where and do u need to bleed the brakes ? i'm not very good at this kind of stuff.:-(

Hope this helps:ok:

Cheers mate. I'll have a go when ive got plenty of time :???:.
