[Tigers] Brakes 3

[Stu Brennan]

Hi Ron:

There is some clearance between a fully retracted piston and the pad.  I
was able to push the pad away from the disk, and the against the the
rubber boots.  I could feel the piston retract. But as soon as I release
them they snap back against the disks, propelled by the rubber.  And I
can feel it the next time I step on the brakes, slightly longer pedal
the first time.

	I measured some of the pads I have and the total thickness of
pad and backer is around .60".

I just measured a caliper with the pistons all the way in at 1.94" -
1.20 for the pads and .5" for the rotor = .024".

Your pads are .010" bigger than the distance in the caliper; if you have
an anti-squeal shim in the caliper it is even worst. 

I would say that you need to thin those new pads to around .60" to have
some clearance.
