Re: Disc Brakes!

[William Cole <wedge64@xxxxxxxxxxx>]

Dan,
Not sure of the MC I put on the car. It's been a couple years since I
did it. I know it's a disc/drum MC but not sure of the bore size. I have
the rears adjusted properly, as far as I can tell. I know I had to shim
the MC out a little after installing it because it was holding pressure
on the front disc's. It works fine now after that.
It may well be the MC is too big a bore and requires more pressure to
stop. I used a semi-metallic shoes on the back, which may not of been
the best choice. I know after I drive the car a while it stops somewhat
bettr. Just seems like it takes too much pressure to get it to do that.
I think I just need a matched setup to make the car stop like it should.
That's why I was thinking of the Master Power setup. 
I guess it would be cheaper to try a different MC to see it that helped
before I drop $1300 or $1400 on the Maste Power stuff.
I do have manual brakes and the cam I'm running is the biggest hydraulic
cam that Racer Brown makes so, power brakes is out of the question.

Thanks,
Bill C.
