brake question

will a small 3/16 brake line going back to the rear drum cause problems like mushy or no brakes?

I thought maybe I wasn't getting enough pressure to the back I thought the rear drums need more pressure like 10. At least I don't have to change the line

Questions:
Is this a custom install?
Disc/Drum?
Do you have a residual valve on the drums? Should have one if you don't. The residual valve holds some pressure to the discs so they don't feel mushy or soft from to long of a pedal stroke to get them to move.

I installed a p valve that installed but that didn't work. So more valves. Just on the rear or front too?

You should have a 10lb residual on the rears AND the front IF the fronts are drum. If they are discs a 2 or 3 lb. valve is plenty. Go to Speedways site and check out their brake hardware.
Brake Selection and Design
They have diagrams to help point you in the right direction.

It goes to one side of a dash indicator bulb, the other side of the bulb is hot with key-on. If/when you have a brake failure, the prop valve will ground that switch, completing the circuit, and light the bulb...

Mushy brakes is air in the system. Air compresses, fluid doesn't. Residual valves will help to keep the pedal travel to a minimum as they don't allow the cylinders/calipers to fully relax so in effect the brakes are lightly applied all the time.
