Forum:
I'm totally raw to this group, but desperate to sort this out, so hope someone out there can help me. I've freed the handbrake cable from the caliper, removed the 2 bolts holding the fixed bracket, but ridge on rotor prevents slipping the caliper off the rotor. To push the piston back in this is what I tried. Tried freeing the bleed nipple while clamping across from the very back of the caliper to the outer pad (that didn't work), and same again on the inside but this time pushing against the rotor itself on the outside using small blocks and a bridge across the outer side of the rotor so that the caliper could slide outwards on the slides if you get what I mean. In any case the piston still isn't getting pushed back into it's cylinder. I don't have a service book, and can't find one online. I'd like to get this done this weekend. What's the secret to compressing the piston back into the cylinder? Any help really appreciated.
stuck piston maybe?
just read post "grinding on brake discs" from 2007. Looks like I'm on the right track, but I'm thinking maybe the guides are jammed or corroded. I've applied quite a bit of compression force. Are the pins removeable with the caliper still in place? Maybe just belt it with a hammer? what do you think?
There should be a shallow hex
There should be a shallow hex top bung on the backpart of the caliper, behind that there is a allen socket to wind the piston in and out

bung at the back
I see what u r referring to. Is that what sets the handbrake initial position? Can u tell me, do I need to undo that 10mm hex head behind the pull-off rubber cap at the back of one of the slides so I can swing the bit of the caliper with the pads away from the piston so that I can slide the pads off the rails?? That was a complicated way of asking "now that the caliper is off the rotor, how do I get the old pads out"?
prob solved; memory failure
OK. I had done this job ages ago. So I forgot about that hex key to pull the piston back ( mine had a stuffed hex, so was a **** to get out), and removing the slide so you can rotate the caliper and drop shoes out and vice versa. Trick is to free the 14mm hex setscrew covering the handbrake screw, and also free the 10mm hex slide pin BEFORE you take the 2 14mm caliper setscrew out. Of course you will have lifted the rear bit of console out of the way (2 crosshead screws) so you can back off the handbrake adjuster (use a 10mm socket ) so you can release the handbrake cable from the clip on the caliper. Slip the clip off the cable down at the caliper and pull the cable back out of the way. With the new pads in and having lubricated theappropriate bits, wind the hex key back in till the pads lock the rotor, then back off half a turn.
I'm writing this 'cos it just might help someone else. Wish I didn't have to find out the hard way.
