[s-cars] Urgent - Caliper retraction

[Fred Munro]

Aaron;

The "self-adjust" feature is the e-brake. As you use the e-brake it moves
the piston out until it is at the proper clearance. If you don't use the
e-brake, the rear calipers don't get adjusted and you will have a lot of
pedal travel.

Thanks verybody for the tips
I made a piece of tubing into a forked tool and managed to screw / push in
the pistons and got her all back together - no sweat.  I retracted the
pistons them all the way so there was a tad of clearance when reinstalling
the caliper /new pads.  Noticed the master cylinder overflowed a little bit.

Next question:
Im sure there is some sort of self adjust feature that is supposed to "take
out the slack".  I does not seem to be working as there is quite a bit of
pedal traver.  More than before.  Pedal is firm.
E brake travel is unchanged.
I dont see any manual clearance adjustment like on older cars.  Whats up?
Thanks again
Aaron
