Hey guys, Long story short, Ive finally got my 54 Ford to be able to drive after 3 years and everything is good but it doesnt seem like the brakes are very good on it for being everything new and non-powered and I cant figure out why? A little history on the setup is on the front of the car Im using new S10 discs, calipers, pads, braided lines and the rear is completely rebuilt early 1957 style 9 Ford (1-3/4 wide shoes) and all new parts inside and turned drums. New 3/16 lines, fed by a 65 non-powered mustang disc/drum master cylinder and a Wilwood proportioning valve to adjust front/rear bias. My issue is, Ive got good pedal, and doesnt bottom out on the floor or anything but it just doesnt seem to stop very well. Pushing as hard as I can on the pedal it will not lock up the fronts or rears no matter where I have the prop valve. As I bring more pressure to the rears it does help the stopping but definently not as good as what I have experienced with manual brakes in the past. Last night I took it out on the road and about 60mph I stopped as quickly as possible and once it finally stopped the front rotors/pads were smoking so I know the fronts are working but they just dont seem very good . Could it be Ive still got air in the lines? Could the master cylinder be too small of bore? Thanks in advance!
