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 ?
If its anything like my mates falcon ute it twists in like a spiral. You might have to losen something on the back of the caliper to let it push in. Hope that helps.
I'll ask my mate what he had to do.
He says he took the hand brake lever off and kinda unwound it? Dunno if the astra would be the same tho, never done one. Give it a go though, u never know.
we have these on the hondas at work and my mums nissan pulsar, its a cross shape in the middle yeh? get a pair of pliars and open them or a large screw driver that will fit and turn them in, don't need to pull the hand brake lever off, they may take a while to turn in, so don't worry if there taking a bit to turn in, use a bit more force and they'll start turning in, there is also a brake caliper tool (square, with round and square/oval points on each side) you can get from bursons and repco for these too that fits on a ratchet and u set the ratchet to do up as your turning it in, may need a short extension, hope this helps, good luck with it.
theres a specific tool to push them back they need to be screwed back in you will destroy them if you try to force them back
make something to sit in the pin holes in the piston & push it while turning it clockwise
