$79.99
Convert brake-pedal force into the hydraulic pressure that operates the braking system with the Dorman First Stop Brake Master Cylinder (M100841). It installs as a direct-fit replacement for the 1979-1982 Honda Prelude, 1980-1981 Honda Accord, and 1980-1983 Honda Civic (all engines), engineered to match the design, function, and performance of the original master cylinder on these applications.
- Cast-iron housing: constructed to match the casting material of the original part for similar performance.
- Durable EPDM rubber: all rubber components use a high-quality EPDM compound for resistance to glycol-based brake fluid.
- 100% new: built entirely from new materials, not remanufactured.
- Strict specifications: made to meet rigorous SAE International standards.
This unit has a 0.813 in bore, two outlets with M10 x 1.0 threads, and includes the reservoir and sensor. Mounting hardware is not included — consult the vehicle service information for the correct fasteners and whether they may be reused. If a failed master cylinder is the cause of a sinking or spongy brake pedal, this replaces it; diagnose the cause first, as those symptoms can have other sources. Country of origin: Taiwan.
Interchange: Manufacturer part number M100841.
