Sticking Brake Calipers (I Think)
Discussion
I have an Astra H 2006 model, apparently these are known for sticky or corroded brake calipers on the rear.
recently the heandbrake has become very "limp" and lose and not really doing much, thinking of getting it into the garage for a checkup.
problem being, after initially thinking handbrake cable replace the garage said very rarely on this would the cable go so quickley like it has done due to corrosion, most probably my calipers.
possible suggestion before getting the car into the garage is to give the rear brakes a good clean, anyone got any idea what is best to use on this to perhaps help free them up again???
also, would I need to take them apart to clean or can I just remove the wheel and clean as they are??
cheers

If they stick it is normally the sliders or the piston. The sliders can usually be withdrawn (although I have no experience of these specific callipers) cleaned up with a wire brush then greased using moly grease or similar high temp (not copper grease)
The piston can get stuck if it goes out of shape or if the dust seals die and crap can get in. In this case you can replace the piston - try http://www.biggred.co.uk/ - but sometimes it's easier and more cost effective to wack a new calliper on.
In all cases you will need to remove disc and pads at a minimum.

Safe, was just a rusty handbrake cable!! happy days!The piston can get stuck if it goes out of shape or if the dust seals die and crap can get in. In this case you can replace the piston - try http://www.biggred.co.uk/ - but sometimes it's easier and more cost effective to wack a new calliper on.
