Car = '40 coupe
frt. brakes = Pete n Jakes disk kit = no issues we have frt. brakes
Mst. Cylinder = Pete n Jakes dual chamber manual w/ 7/8" bore, using our orig. push rod.
WilWood proportioning valve to rear brakes.
Rear brakes = orig, new
Problem = While we bleed the rear there is no pressure of fluid. No brake. Pedal goes to floor.
With in the first 2" of pedal travel we have frt. brakes grabbing. Adj. push rod with no positive outcome.
Was sent a replacement mst. cyl. on Petes dime. No difference.
I found early forum about dual chamber for drum brakes stating the orig. rear cyl. are 1- 1 1/8 bore and the mst. cylinder in my case should have been the same. Pete's catalog states our car should have the one we got.7/8".

What say you good members who have helped me enjoy my '40 Sedan as an often driven car? Now My Dad needs help.
