Yes, I have travis's kit w/ a 1-1/16" bore master cylinder on my 78 montecarlo. disc/disc all around, 1/4" hard line run through wildwoods por. valve. to rear into factory tee,then 3/16 hard line to stainless lines into small gm metric (single piston) calipers. Same as the fronts. My problem after bleeding,pedals seems to be not hard enough,I put car on jack stands and ran the car to see if brakes work, the seem to stop fine wants i set valve ,it wasn't releasing rear brakes, went for a ride and rear brakes calipers want to stay locked on pass. side, caliper seem stuck ,replaced,w that side hard line going into stainless line,worked okay,on jacks. Drove again and locked again, all 4 rotors was very hot to the touch. ANY SUGGESTION,THANKS.
