SSBC disc brakes won't stop

Yeah, you don't want 2 prop valves in there. Don't open up the adjustable one all the way; close it down all the way, to take its action out of the system for the time being. The residual valve can be dealt with later; it would not cause lack of brakes but just the rears dragging slightly all the time.


^^THIS RIGHT HERE^^

You certainly don't want 2 prop valves and as I said earlier you may not want ANY

The residual valves ARE NOT this problem. They are a very very low pressure valve, the only thing they would cause, is a slight drag of the pads. Look in the shop manual, which shows how to remove them. On mine, I simply poked nails in through them from the fitting.

Here's a generic photo. You can thread a small screw into the seat, and use a claw hammer to pull the seat out. Discard the valve and spring, and re-insert the seat
