Are they really needed when you have disc brakes in front and drum brakes in the rear? I’m thinking of installing one in my 1954 Chev Belair. If you have done this, let me know how it went. Thank you.

theoretically you could use one of the knob adjust ones, for the drum line, I think. You also may want to do residual valves especially if your master is still mounted under the floor. I've got the knob adjust one and no residual valves and I can't say I'm happy with the brakes on my coupe. If anyone else ever drove it, I'd overhaul the brake system.

Here's a good thread on brakes & proportioning valves.
