Description

This is the direct replacement of the unique square-profile O-Ring found on the original brake system on the MH-1521 Broussard. This are specially made to the correct dimensions and proper durometer. It is very important not to replace them with just regular round O-ring dues to the possibility of the O-ring rolling inside the square grove and locking/twisting preventing the piston from retracting. This will cause the piston to jammed and lock the brakes when you need them to get loose. This seals are made of Nitrile Butadiene Rubber also know as (NBR). It is a synthetic petroleum-based rubber prized for its exceptional resistance to oils, fuels, and chemicals.
