Post subject:  Adding brake booster
I want to add a booster to my friend's Dart's drum brake system just to improve the feel at the pedal for until I convert it to disc brakes, and I can get a booster/master cylinder cheap at the local pull-a-part, but my question is: is it pretty much plug n' play for adding a power booster with its own MC?

Obviously I'll have to bleed the entire system afterwards, but other than that, anything else I'll need to do?

One problem I had on my '63 Dart is that there is a "rib" above the master cylinder on the firewall. The lever for the booster adapter hits this rib and prevents the pedal from coming all the way up. The adapter gives a 4 to 1 advantage, so 1/2" less travel means 2" less at the brake pedal. The rib is on '63-'64 A-bodies. You will probably have to flatten out this rib to get full travel in the brake pedal. I just put a turbo on my slant and didn't have room for the booster so I took it off. It turns out that the pressure needed feels the same as a 9" setup so I am not putting the booster back in.

This one's a '70 with manual drums (but not for long :twisted: ), so if that's the only thing, it sounds like I'm good to go once I can get to the junk yard and grab one.

Post subject:  booster
Question:What are the odds of a 30+year old booster having rotted rubber parts? Answer: sometime soon ,some one will loose allot of mileage due to a growing vacum leak followed by a possible loss of needed braking power and for sure down time replaceing somthing that doesn't last longer than fuelpumps radiator hoses or fan belts :shock: Free advice from some one whos been there,, save your time and money and buy a re built if you can pull one for free , use it for the core and save $20 Bruce
