Re: 200q parking brake now brakes help more

Don;

    You don't need the special tool to turn in the pistons. I use a pair of
6" needle nose ViceGrips. I close the pliers and set the tip separation to
fit into the slots in the piston to turn the piston in. Be careful you don't
tear the boot - it may be stuck to the piston and you may have to lift the
lip a bit to make sure it is free.
    You don't need to bleed the brakes if you turn in the pistons. Turning
the pistons in forces brake fluid back into the master cylinder reservoir.
    Turning in the pistons and allowing the brakes to re-establish the
proper pad clearances should resolve your problem.
