Dorman - First Stop Brake Master Cylinder P/N:M105876

The Dorman - First Stop Brake Master Cylinder M105876 converts the force from your brake pedal into the hydraulic pressure that operates the brakes. It installs as a direct-fit replacement for the 1982-1983 American Motors Concord, 1982-1983 American Motors Spirit, 1982-1988 American Motors Eagle, 1984-1989 Jeep Cherokee, 1984-1989 Jeep Wagoneer, 1986-1989 Jeep Comanche, and 1987-1989 Jeep Wrangler (all engines). It is precision-built to match the design, function, and performance of the original master cylinder on these listed applications.

• 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.
• Built to spec: made to meet rigorous SAE International standards.

This unit has two outlets (rearward 7/16-24, secondary 1/2-20 thread) and a 0.938 in bore, and it includes the reservoir; no sensor is included. Signs such as a sinking or spongy pedal can point to a worn master cylinder among other causes, so diagnose the fault first — if a failed master cylinder is the cause, this replaces it. Mounting hardware is not included; consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: China.
