stage 1 (new version) - now includes a bolt -on option for the rt. caliper, so you keep the emer. brake, and rear brake line dist. block bolts onto the existing stud with no problem. also remember to remove the rear rear screw on the master cylinder befor installing it. (you only get 1/8 turn out of the allen wrench when you tighten up the rear screw. also adjusnt the pushrod adjusting nut on the rear master cylinder so you get to port open when you release the pedal. then bleeding is quicker. . older versions. local shop just installed a new version on a '11 t/g. and p/m fixed previous problems.
