That's interesting, Wayne. How do they get enough mechanical advantage on
the disc pads? Does the cable work another hydraulic cylinder? If the
calipers were forced forward, the disc cylinders would just get pushed into
the calipers. I guess it's my turn to go searching to find the answer. )
Intriguing.

A very good question. The handbrake on my Tib probably needs adjusting (I
am too busy / lazy at the moment) but I don't recall it ever being
particularly effective. Maybe that is the reason. That said, it never
rolled down my sloped driveway either.

Not that I can tell, but I seriously doubt it based on how it was attached
to the rear caliper.

I am not following you here - the calipers are side-to-side not fore-aft so
how can they be pushed forward? What disc cylinders?

lndeed. Check Webtech ... its exploded diagram shows what I saw
assembled. :-)

On the point you didn't follow, I made it as confusing as possible. ) I
was thinking just as a caliper and not fore/aft on the car. Forward was
moving out of the caliper and back was retracting into the caliper bore.
There are pistons on each side or just one side of the disc that move back
and forth. I see that there is a cam that moves the piston forward. One
more thing to leak............ Oh well.
