Who says trigonometry doesn't pay!
Taking a break from my caliper rebuild job to design a template to measure the required 20 degree angle for the piston. Didn't have a protractor but I did remember enough trig to figure it out.
FYI. A triangular piece of cardboard 4 inches wide by 1 15/32 inches high gives you the 20 degree angle and fits well in the caliper.
Whoever did my brakes previously had the piston angles all screwed up. One piston was at the correct angle but the elevated portion of the piston was at the top. The other piston was no where close to 20 degrees. I assume both pistons should have the recessed portion at the bottom?
Other than brake squeal, is there anything else that having the piston at the wrong angle causes?
Thanks Wayne, the book made this somewhat easy. First time trying this, I had one caliper off and a new brake line on in less than an hour from starting. I need to buy a second book for the coffee table because I can see this one is going to get dirty.
