The Russell 10 lb polished residual valve is sized for drum-brake circuits where greater retained pressure is required to overcome return springs. It prevents brake fluid from draining back into the master cylinder, keeping shoes or caliper pistons slightly primed to reduce pedal travel and improve response. The polished finish offers a clean look on brake lines while improving pedal feel.
