Brakes, Brakes and more Brakes

Front and rear templates are the same I think. The angle affects self servo function, and significantly it affects noise generation (brake squeel). I don't think its a precision issue though. You can get pretty good visually (without the guage) - 5 or 10 degrees won't cause a crisis).

On a Porsche site, I read the best explanation I have thus heard for the alignment issue on the piston cutouts.

It says that it is to allow the pads to pivot slightly under pressure so that the leading edge of the pad does not take all the wear.

This makes some sense since if the pad were aganist a flat piston, then under braking the torque cpuple on the pad would be trying to rotate it leading-edge-first down into the rotor.

Sure enough, if you look at the templates, they are aligned so that a line drawn across the two "teeth" of the cutouts is perpendicular to the direction of the rotor sweeping under the pad.

Thanks for all your help,
I did reverse the calipers and got the bleeders on the top. Problem solved. When I worked on the slave clutch cylinder I made sure the nipple was on top prior to bleeding the system, I can't believe I ovelooked the calipers. With all the excitment of perfection I guess I got sidetracked.
Thanks again to all of you for your help
