Hi Anyone know if there is a Holden Astra / Vectra web site like this one ? Im replacing my rear brake pads on my girlfriends Astra and have come on a problem I have not seem before. Normally you pull the caliper off and use a G clamp to drive the piston back. The Astra sucker will not push back and seems to have some sort of ratchet interlock on the handbrake caliper lever to prevent it being pushed back. Any ideas on how to push the piston back ?
