The Russell 2 lb polished residual valve is a compact line-mounted valve for disc brake circuits that retains a small amount of pressure to prevent fluid from draining into the master cylinder. By keeping caliper pistons slightly primed it reduces spongy-pedal feel and accelerates engagement for a firmer brake pedal. The polished finish provides a neat appearance on brake lines.
