How to front and rear brake pads removal.


Just thought I'd put this up as we don't have one yet.

Jack up and remove wheel from the car to gain access to brake.



Next take out the guide bolt from the bottom 10mm



you may need to slacken the top guide bolt no need to fully remove it



then pull the housing out and up





Tie the housing to something (although I didn't)

To remove the brake pad just pull it out towards you the back one pulls out away from you



remove the brake pad retaining springs they just pull down or up (give them a clean).



Refitting is the reversal of removal the guide bolts need to be torqued up to 28 N.M (21 lb ft).
If you need to push the piston back in Vauxhall use tool CH-6007-B but I find a couple of bits of wood and a G clamp is just as good.


Now for the rear

again jack up and remove wheel



fully remove the calliper vibration dampener 13mm spanner





again pull the housing out and up





there is not a lot of room here hence no pics but the pads pull out the same as the front as do the retaining springs.

Again clean the retaining springs
refitting is the reversal of removal the guide bolt and calliper vibration dampener need to be torqued up to 28 N.M (21 lb ft). Not having a torque spanner I just did the calliper vibration dampener up nice and tight.
If you need to push the piston back in Vauxhall use tool CH-6007-B with CH-6007-50 adapter these are wind back at the rear so you will need to wind them.

Thanks to JohnL for supplying the following pics on rewinding the pistons on the rear.





Not sure if you can see from the picture but I bolted the top of the calliper back up which held everything in place and allowed me to concentrate on turning the rewind tool. and not worry out holding the calliper and looking out for the brake pipe.

Total job took no more than 30 minutes complete.

Number 7 was used on the rewind tool.
