Re: power brake booster, etc.

["Mark Price" <mprice@xxxxxxxxxx>]

My dad used a master and booster from a late 60's drum brake Ambassador on a 67 Ford 1/2 ton pickup cause he was tired of standing on the brake pedal to get it to stop.
He had to redrill the brake pedal itself after mounting the booster. He must have guessed right on the ratio, cause I know he sure was happy with it when he finished it and drove it.
Another case of a Rambler part fixing a Ford!

>Whatever you do, you need a master cylinder for disc/drum if you are running a disc/drum setup. Drum brake master cylinders hold residual pressure to overcome the springs in the drum brakes, and discs do not. A disc master cylinder on drum brakes will not stop the car even if you push the pedal with both feet (I tried it). A drum master cylinder on disc brakes will keep the brakes slightly applied, due to the residual pressure valve in the master cylinder. I have mixed boosters and cylinders with great luck, providing they are the correct disc/drum master cylinder. I would order a master cylinder for the year/model of booster you have and adjust the push rod to have a very small amount of slack when the brakes are not applied. I have even elongated the holes for mounting the master cylinder and used grade 8 washers to reinforce the holes. You can find all sorts of boosters, cylinders, and combo units on Rockauto.com. Happy motoring and stopping.
