handbrake, Clio V6

Just fitted the new rear discs and pads to my car, wound back the piston as instructed and now find I have no handbrake at all on one side, The handbrake lever moves when operated by hand but feels like it is not actually doing anything. Had a similar problem a few years back and (a local rather than specialist) garage insisted on fitting a new caliper, infact this is that caliper which has done very little miles since. Am I doing something wrong when winding back to cause this or what? Given up on it for today!

Did it work before on that side
If the lever is moving but not 'clamping ' then I'd say it's gone over center and the actuator cam has come out .That's if it works anything like a GTA one

Mark, it might be worth checking the plunger cam (item 8 in LH pic below) has not been displaced when you wound back the piston. It pushes on the adjusting screw when applying the hand brake, which turns the shaft, (item 7 RH pic), pushing the piston in.
By removing clip 3, and peeling back the dust cover, you will be able to get to it.

.........Lee has just beat me to it

thanks for the help John and Lee, although they are not the same as a GTA item, (they are 610 type) the principle is much the same. Will take a look when I get a chance. Seems countless owners of these cars change their pads without problem so just want to know where I am going wrong.

.............here`s the 610 one,.....as you say, similar in principle.

Well, cannot say I nailed the problem.....after a brief look under the rubber boot at the rear of the calliper to check nothing was actually broken,I just started again, removed the pads, got someone to press on the brake pedal to move the piston out again (not too far!) Wound back again, re fitted pads and now have a working handbrake. Also removed the centre console enough to get a few turns on the handbrake cable adjustment nut (not easy with the seat in place). Just hope it doesnt go ping when the MOT'er pulls the lever up. My advice to anyone changing pads is to open the bleed nipple and attatch a pipe and container to catch the fluid when winding back the piston, this will help prevent the reservoir up front from overflowing and allow the piston to wind back easier. If possible also remove the handbrake cable from the lever on the calliper. Not easy if the calliper is in place but if changing the discs, the calliper will have to come off anyway which will allow enough slack in the cable to allow it to be released.
