Re: 146 rear Brake piston problem
Pongo, I have been there myself trying to push back 146 brake pistons with clamps, screwdrivers etc and with similar small success.... As purple says get down to Halfords and invest in the correct tool.
Not only does it make the job 100 times easier it also helps make sure the pistons are free when it all goes back together.
If you use the screwdriver method you also run the risk of damaging seals which usually cost a lot more that the tool costs.
