Bleed Nipple Screws

Frentech standard brake bleed nipple screws are precision made from mild steel and are zinc coated to protect from corrosion. They are engineered to stipulations equivalent with original equipment.

Brake caliper bleed nipple screws are located at the top of a caliper. They are used to allow bleeding by creating a temporary opening in an otherwise closed hydraulic system. The threads are tapered for a snug fit, to prevent fluid from leaking. The screw is hollow with a small hole, so that when the screw is loosened, fluid and air can move through the screw.

Fluid can’t be compressed, so when force is applied at the pedal it is transferred almost immediately to the brakes. When air is in the system, the maximum amount of pressure that can be applied to the breaks is reduced and brakes can become spongy or can stop working completely. This is when the brake bleed nipples needs to be loosened in order to purge the system of air.
