Rear Pad replacement

[RAW-SEWedge]

How do you get the rear pistons back into the caliper ?

I’ve tried turning the piston clockwise like the bible suggests with a pair of circlip pliers but it don’t seem to be moving ?!

I’ll try and get the correct tool from Halfords tomorrow but any other suggestions would be welcome.

Does the hand brake cable have to be released for the piston to retract ? I can’t seem to get that off either ??

Ha !!
caught me to that one
you notice on the pistons there are slots well put a blade across them and SCREW them back into the calipers, they go right in very easily and the new pads will drop in .

Cheers Simon,

I've been turning the piston clockwise but I'm sure it hasn't moved

I haven't been able to remove the handbrake cable yet. I've slackened it off but can't seem to get enough play in it to get it off. Do you think this could be the reason why the piston doesn't appear to move ?

Its just about possible (but you can end up faffing around for hours) without the tool and trivially easy with it. In any case, you don't need to slacken off or remove the handbrake cable, just ensure the handbrake isn't actually on when you do it!

I made a tool for turningback the piston.
Its a socket which has an O/D similar to the indents on the piston face,with some cap screws protruding and welded on the side.
It works really well and of course can be used on a ratchet.


Ta daaaaaa !!!!

mail me for pics/hints.

go to half wits or a motor factors, and get the right tool for the job, else you end up buggering the seals on the caliper's piston.

Was it really worth it? Unless you're absolutely determined to do it the hard way, or don't have the option of buying the right tool for the job, I would say this is a no-brainer. We're only talking about a couple of quid here versus a whole lot of hassle.

Halfords near me didn’t have the tool, but I managed to retract the pistons in the end.

Thanks for all your feedback guys

I used a spanner off the angle grinder, which located into the slots ok and then applied some pressure to the piston with a cycle crank puller.

As you can imagine it was a total pain in the arse and I have some nice battle scars on the knuckles to show for it

I have some rear brakes now thou’ which is always a bonus. As soon as a I find one of the tools I will grab it because it sounds like a good investment.

I found a copy of the Haynes manual for the Sierra in PDF on the web if you’re interested

I made it a work ,got the bits from work and so yes for me it was worth it!!!!!!

Sorry I didnt comply and like to make things.

It also means you can use a ratchet for the job.

Not my idea of a no-brainer,just some ingenuity.OK

It may take a bit of effort but the enabling of the use of the ratchet seems to make this the best solution.
