<< 6. Install the pistons in the cylinders. Make sure they get started in
straight, and not cocked. Once started, they can be forced into the
cylinders with a C-clamp. After all seals are installed, push the pistons
all the way down into their cylinders. This gives clearance to install the
brake pads, etc.
7. The outer dust seals are a little tricky to install since the clearances
are so tight. As I recall. you get the seal lip on the side toward the
cylinder into the piston first, then work the outer lip into the caliper
housing as you push the piston in. Perhaps someone else can give you a
better description of that, since it has been a while since I did it. >>

I just did this, and those directions are correct. Hint: don't press the
piston all the way in before you put on the outer seal and metal ring. Put
the seal and ring on the piston and press them in together. I cut a piece of
1/4" plywood to fit over the piston and seal and pressed them in with a
c-clamp. I only bent one in the process, so you may need an additional
rebuild kit (or two, or three) unless you are VERY patient.
Lubricate the seals and pistons during reassembly with special brake assembly
lubricant or brake fluid. If the pistons can not be cleaned to be mirror
shiny with NO scratches or corrosion, REPLACE THEM!!! They are not expensive
and the seals seal on the pistons, not the cylinders. The cylinders can have
a bit of discoloration but should not be rusty.
BTW, the pistons have a detent on the outer surface. Make sure this detent
is located toward the LEADING edge of rotation of the rotor. That is, as the
rotor turns (sounds like a soap opera at an auto shop) the lowered part of
the piston should point toward it. (To the bottom of the caliper when it is
refitted to the car.) No explanation was given as to why you do this in the
Lockheed kits I got, but I suspect it is to reduce vibration.
Remember, when working on brakes, keep everything clean. There can be no
particles in the calipers when you reassemble or they will destroy the seals.
The only other thing you need to know is what kind of brake fluid to use.
LIST?!?!?!
