Have a ’66 Comet Caliente that was converted to disc brakes before I bought it.Had original single bowl Master cylinder and vacuum booster. Both were leaking so I replaced the vac. booster and upgraded to a duel bowl master cylinder. Seeing that front brakes were from a ’68 Fairlane I installed a ’68 fairlane master cyl. Rear is from a Lincoln Versailles. Problem is that while the brakes do stop the car the pedal is very low, goes halfway to floor. Another problem is getting enough leverage to e-brake cables for them to operate properly and for the rear disc’s to work. Anyone do a similar conversion or able to offer any help? The Fairlane M.C. is a 15/16″ bore, brand new.
Purchased and installed a new master cylinder (Wilwood) with a 1&1/8″ bore. Pedal now higher and does’nt drop as much. I was informed that with the ’68 Fairlane m.c. I was not able to push enough juice.
