I have a brake problem on my 1950 F-1. The setup has a TCI IFS front suspension with disc brakes and a Ford 8" rear end with drum brakes from a '68 Mustang. I have a CPP conversion with a master cylinder, brake booster and proportioning valve installed.

The brakes have good stopping power. When stopped, the brake pedal returns quickly when depressed however when moving the brake pedal tends to return very slowly causing the bakes to drag. If I return the pedal manually, all works fine. I called CPP and they said that some installation need a pedal return spring. Does this make sense.

 

If it is floor mounted, then a return spring would sound possible.

 

I would go with a return spring also. Keeps the weight of the pedal off the master cylinder pushrod and speedy returns. Could probably use the stock return spring.

 

We installed an aftermarket kit in a '37 Chrysler. The kit required a return spring. Install one, and you're good to go.

 

Yup! That did it. Thanks to all for the input..

 

At No Limit, we make P/B kits for many trucks, and yes, many do need a return spring. 55-59 chevs had them stock. Slow return is common, especially with low vacuum, or tight fitting carpet.
I once was fortunate to have lunch with a guy who built F-100's at the factory. "When we built these", he told me, "They we're little more than 'Tractors with Windows', now, you guy's are trying to make them into Cadilacs". I always try to remember that.
Have a great day!
