Dorman - First Stop Brake Master Cylinder P/N:M80568

Turn brake-pedal effort into the hydraulic pressure that operates your brakes with the Dorman First Stop Brake Master Cylinder M80568. It drops in as a direct-fit replacement for dozens of classic trucks, vans and SUVs — including the 1969 Chevrolet Camaro, 1971-1972 Chevrolet C10 and GMC C15/C1500 pickups, 1972-1973 Chevrolet G10 and GMC G15/G1500 vans, 1975-1978 Dodge D100, and the 1974-1980 International Scout II (see the Buyer's Guide tab for the full list).

• Cast-iron housing: constructed to match the casting material of the original part for similar performance.
• EPDM rubber components: made from a high-quality EPDM compound for resistance to glycol-based brake fluid.
• 100% new: made entirely of new materials, not remanufactured.
• 1.125 in bore, two outlets: secondary outlet thread 1/2-20; made to meet rigorous SAE International standards.

When you press the pedal, the master cylinder forces brake fluid through its two outlets to the hydraulic circuits. If a worn or leaking original is behind a sinking or spongy pedal or fluid loss, this unit replaces it. A reservoir is included; a sensor and mounting hardware are not — consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: China. Manufacturer part number M80568.
