Re: Disc brakes.

[moparbikeguy@xxxxxxx]

I used '76 "A" body brakes on my 1967 race only Cuda. They were absolutely great. I had no trouble stopping with 125mph trap speeds. The master cylinder that I used on that car was a stock manual brake 1976 Dart.
My '65 uses Wildwood front brakes and an aluminum master cylinder. I like the Wildwoods because they are really light, but in all honesty, the stock 1976 "A" brekes stopped better.

Thanks Dan,
I did get the rebuilt calipers for a 73-76 A body car. Just don't know
the piston diameter of the MC. And I'm sure I have the bleeder on the
top. I did bleed them the way you described. I've bleed brakes many many
times in my life. I may try a different MC before I go and buy a whole
new disc system.
