Which master cylinder bore size to use for power disc Kelsey/Hayes
I have owned K-H 4 piston brakes on my 68 FSFB for years and the only issue I have with them is the pistons stick. Change seals on the pistons and replace any pitted pistons. This is paramount to getting good braking on the front, and as other said, a proportioning value is absolutely necessary.
Ultimately, I went with the 11.81" cop rotors and '73+ spindles/brakes. These are absolutely the best brakes I have had on my Cuda, and they are 100% factory, just not from '68. In the rear I did the Jeep Liberty swap to disks. Low-cost conversion per Mopar Action article and they work great.
