do modern brake boosters improve braking power over the older style that pushes on the pedal rather than the master? my 60 chrysler has never felt right since i converted to disc. and im wondering if a modern booster would help.
Drum brakes Have a degree of 'self-servo' action on the leading shoe, Changing to discs will have negated this, hence the brakes feel diffrent. Most automotive brakes work at 600 to 1000 psi, regardless of whether the system has a booster or not, So if your set up makes the required line pressure when you stamp the pedal that's kind of it. A simple pressure gauge can tell you if you have enough poundage. If you have the line pressure and the brakes are still feeble then the problem is the quality of the disc conversion kit ( I have met pletty that were utter junk )
Did you use a combination valve? What master are you using, and what brakes at all four corners? the system needs to be balanced, when mixing and matching, they don't always work as a bolt on. I have a disc kit on my 53 chevy (manual) and 55 desoto (power)
i used a combo valve. the master is a corvette 1 1/8th bore. the fronts are 76 monte carlo calipers. the rear brakes are drums from a 67 newport. what did you use on the 55 desoto? im going to be putting discs on my 56 desoto. if youve done it and got it right, might save me the h***le of experimenting.
