    Evening everyone.

    I'm looking at a new front disk set-up. The whole kit-Booster, proportioning valve, spindles etc...

    My question is: Should I stick with the almost 50 year old booster with no known issues or replace it with one that comes in the brake kit? Not sure of the quality of these new(more than likely Chinese) made boosters.

    Let me know.

    Thanks Fellas. I ordered the AFXDC06CS kit from The Right Stuff.

    Should have all I need except for a few pre-bent lines.

    I installed the similar kit. Works great. I think they recommend using the new booster with the kit... plus it looks nice and new.

    Big difference in feel & performance compared to front drums?

    How complicated or easy was the overall installation?

    It was super easy to install.... new porportioning valve, lines, master cylinder, spindles etc....Definitely more aggressive stopping... i decided to change when a car pulled out in front of me, had to slam on the brakes and the driver side front wheel cylinder exploded.... lucky i didn't hit the guy... decided disc brakes were the way to go...

    Kinda funny, but my 72 GS I had,I put drum brakes on to race.I backed the adjustment off for easier rolling resistance. Ran 11.90's in that car. Now I have Wilwood brakes on my car and think what a fool I was for running the drum brakes..Stopping makes me feel better in my old age..

    Funny is,we went to Island race track 20 years ago in NJ.It does have a short track at the end.This other friend was with us with a 71 GS with disc brakes running 10.90 11.00's On my race car I have front aluminum drum brakes,non power.We were running 9.teens over 140 MPH.He complained that he could not stop,so he was going to slow down from then on.after the 1000 foot mark,we had no problems.Don't forget,this guy makes a living fixing cars ,he has a shop in Brooklyn,NY.

    You might consider calling Booster Steve at Power Brake Booster Exchange. He could rebuild and go through your original booster and it
    will look like new again. He knows his stuff and is a car enthusiast himself.
    Tell him Eric sent you.
    His number is 503-238-8882
    Happy New Year!
