What Bendix master cylinder was used on a front drum brake car? I have seen pictures where these cars did NOT use the booster and offset bracket. Secondly, where we can see a brake booster and offset bracket, What Bendix master cylinder was used on this application? I guess this would be with front disc brakes? I've been told that ALL Hemi Roadrunners used the booster and disc brakes but I've seen cars with only a master cylinder w/o the booster. I guessing these were front drum brake cars? What is correct? Maybe some original car owners car to chime in. Thanks for your thought. Buddy

I'm absolutely NOT sure about the master cyl's yet believe there are two different ones 1 for manual drum, the other for power drum or disc.

Buddy A 69 HEMI Road Runner could be equipped with either manual 4 whl drum brakes or power discs that used the offset dual diaphram Bendix Booster....your "restoring" a HEMI Road Runner, what was it equipped with?, or are you looking to "upgrade" the brake package?

If the car was ordered with the A34 Super Track Pak 4:10 dana then it had power disks std. A 4 speed ordered with the A33 axle could have manual drums. That's the way my original 69 Hemi Charger 500 is equipped. 4 speed with manual drums.

I enabels you to remove the booster to adjust valves etc., without having to remove break lines. I bought mine from the Ram Man after first trying a "chevy" copy that didn't work. Expensive but it is not only correct, it works.
