Description
5/16-24 NF bleed screw (bleeder valve) for a caliper or wheel cylinder. Opening this screw with the correct wrench, while the brake pedal is pumped, lets trapped air and old fluid escape during a bleed or fluid flush; closing it re-seals the hydraulic circuit. Matches the 5/16-24 NF bleeder port thread found on many calipers and wheel cylinders — check your caliper’s existing screw thread before ordering to confirm the match.
