Talked to Jason @ Pete n Jakes. The way he explained the 7/8" bore, its needed because of the front disk piston. If it was larger than 7/8" there would be less pressure to work with. Or something like that. it made sense as we talked, its also what Dad reads in articles in many magazines. If people use a larger bore they don't have enough pressure. We will try the bleeding methods above.
Thank you. Will RSVP.
Most important to insure rear lockheed brakes are adjusted right and the shoes make contact over the whole surface by being ground to fit. Until you have that all bets are off.
