[V8] Pushing in rear brake cylinders

[Seamus O'Carey]

In the past I found a cheap old socket (if it says Korea or China on the
side it's a good candidate) that was the same diameter of the piston.  Then
using a cutting wheel on a dremel I removed about 1/4" off the front edge,
while leaving two little nubs that fit into the grooves on the brake
piston.  Then I either put the caliper in a vice (just to hold it still) or
found something firm to hold it against while I used a socket wrench to turn
the piston while applying pressure.  You don't need to apply very much
pressure, since it's the turning that's really driving the piston back into
the caliper.

I lost the socket I made, though, so when I did the rear brakes on the V8 I
just went and rented the brake tool kit from the local Shucks (might be
Checker or Kragen Auto Parts where you live).  I had to pay a deposit, but I
got it all back when I return the kit.  It came with an assortment of
adapters for a variety of applications and a clamp for applying pressure.
If I remember correctly I got 100% of the deposit back, so it ended up being
free to rent.
