Ft Disc Brake Problem - '68 Impala

I'm still trying to figure out why it takes extreme effort to stop the car - '68 Chev Impala Wagon. Previous owner did a disc brake conversion. It has a brand new Power Booster, 20 lb vac, correct dual master cylinder and proportion valve. I pulled one front wheel today and it appears that the calipers are not working, or just barely working. There is no clear shine on the rotors (or surface rust if they have been sitting). They just have a dull smooth finish. There are no leaks. Just wondering where the problem might be? Everything appears to be almost brand new, hardly ever used with the disc conversion.

how much does the pedal move when you apply the brakes? is it soft or hard?

when you hit the brakes does the car nose dive? that would mean your just running on front brakes i would try bleeding the whole system and check to see if your drums are adjusted properly. if you jack up the rear wheels and spin the tire in neutral there should be very little drag on the drum brakes. if you press the brake pedal down while the rear wheels are spinning you the shoes should be engaging fairly quickly if you go halfway to the floor before the rears kick in they need to be adjusted.


just a few things to check good luck.

Disc's take more fluid to work the calipers than wheel cylinders do on drums. Maybe the actuator rod is wrong/needs adjusted.???
