Brake System & Fitment

Manual brake master cylinders typically use a smaller bore and deeper pushrod hole to maintain the required hydraulic pressure. Confirm the 1-inch bore, deep-piston requirement, ports and complete manual-brake configuration before ordering.

Bench Bleeding Required

Bench bleed the master cylinder in a vise before installation. Use clean brake fluid specified for the application, keep the return hoses submerged in the reservoir, and slowly stroke the piston until air bubbles are eliminated. Do not allow the reservoir to run dry, and bleed the complete brake system after installation.
