I hope that somebody can assist.

Against my wifes wishes I decided to change the pads on the rear
disks. I have changed hundreds of sets of brakes in my life how
difficult can it be.....

I removed the two bolts holding the caliper, removed the old pads and
spent the next 3 hours trying to force the piston back into the
caliper, I have opened the reservoir in the engine and even opened the
bleed screw while trying to push back the piston. I remounted the
caliper to get the best leverage and have bent every too I have that
fitted in and in anyway gave me any leverage.

As a last resort, thinking I may be missing something, I attempted the
whole exercise while pushing the hand break mechanism, the result is
that the piston has moved out even further and I cant even put in the
old pads again.

I am in South Africa and there is not a single Peugeot dealer that is
open until Monday, has anybody ever had a similar problem, please tell
me I am missing something.

At the point where a rag in the fuel tank is a great idea.

Thanks
