Hi all

I'm going to revert back to my old ways and start doing a
few
maintenance jobs on our vehicles
Is there a universal tool to push the piston back when
changing pads?

BMW 330
Grand Cherokee
Mecedes vito van
Citeron berlingo van

If the Berlingo's brakes are anything like a Citroen AX with
ATE brakes,
then the handle of a wooden mallet should do the trick!

Is a special tool ever necessary?
I've changed pads on many different makes, and never had any
problems pushing the pistons back, using ordinary tools,
occasionally supplemented by a suitably sized piece of wood.

It can help with rear calipers. On a MK2 Golf they need to be
pushed back and twisted as they're on a thread due to the
handbrake mechanism.

IME the self adjusting screw type can be fiddled without using
special tools.
A separate operation though to just pushing the pistons back to
fit new pads to most calipers. I see little point in having a
tool just to do that.

wait till you try to change the pads on a late Merc. you hae to use a laptop to get the 'pistons' to retract (so I am told) you then have to tell it how thick the new pads are !!!!

Trust you to come up with something to defeat my argument. :-)

Sounds like a way to stop owners from doing what is usually a relatively easy DIY job, and charge a lot for doing it.
No worries for me though. I doubt I'll ever own a late Merc.
