Sierra Rear Calipers... (help needed)
Hi All,
can someone please advise how to push back the piston in a Rear Sierra Caliper?
Is it a wind in one as per Audi's or just a push back in one as per the pushy-back-inny-typey-ones ( )...
thanks in anticipation of your help,
Steve.

They are wind in, but the trick is to apply some pressure to the piston as you do so. I find that a good size "G" cramp does the job, and
turn the thing in with a pair of 90deg circlip pliers. HTH Ray
To make a car go faster, just add lightness. Colin Chapman - OR - fit a bigger engine. Chippy

Steve, an angle grinder spanner is a good DIY substitute for the proper tool , just screw in clockwise making sure the dust seal doesn't deform.

They can be awkward little beggars can't they - I was messing about for ages until I got it wound back - brand spanking new too! I'm
changing them to Wilwoods soon anyway 
Cheers,

I use long nosed pliers to push and twist at the same time. In the past on other cars I've put a big wing nut on a long bolt with a lock nut and
push and twist with a ratchet and socket.

thanks for your replies...
to be honest they went in really easily!
I put a large G-Cramp on it, (they all have broken ends at work with no cup and just the ball remaining!) and just slipped a grinder spanner [cheers
Mark  ] over the end of that. Applied slight pressure with the clamp, and turned the spanner.
Job well done, they'll be going on in a few hours time!
