I've got a 1987 Audi 5000 CS Quattro, rear brake pads need replacing,
and one of the calipers is tough to turn the piston so it will retract.
The other caliper screwed in easily just by using a large 6-sided 12mm
I'm guessing this is the tool I need:
"Draper H-PEN 1/2" Square Drive PENTAGONAL GIRLING BRAKE BIT"
Does anyone know where I can get this tool (or an equivalent) relatively
cheaply in the USA? I can order it from the UK for about £9.90 ($19.32)
but I'd like it cheaper and quicker if possible.
