Back again with another plea for help! I switched the drum brakes on our '66 Comet to manual disc brakes. We also put a Lincoln Versaille rear end under it. The problem is this: the car is extremely difficult to push now. When I want to push the car up in the staging lanes, I can hardly move the car forward without help. I am wondering if there is that much drag on the car, how much is it slowing it down going down the strip?
I used a new manual disc dual master cylinder listed for a '67 Fairlane, but I am wondering if the distribution block off the Lincoln is wrong, since it was for power disc brakes. Could that cause a problem in the brakes being too tight? Please help!!!
My wife wants to get back to the drag strip yesterday..... Thanks!

Check your emergency brake levers on the Versailles calipers. You might have to wire them up. You also might have a sticking caliper, are they fresh or did you use the old ones?

could also be the residual pressure valves in the drum brake master cylinder.

I'd use a different master for discs.The aluminum late model Mustang one (94-up) perhaps. You can also remove the residual valves
