Turn brake-pedal effort into the hydraulic pressure that operates the brake circuit with the Dorman First Stop Brake Master Cylinder M36218. When you press the pedal, the master cylinder pushes fluid through the outlet to the wheel brakes. It installs as a direct-fit replacement for a long list of 1960-1966 Chrysler, Dodge and Plymouth applications — including the 1960-1964 Plymouth Valiant, 1962-1966 Dodge Dart, 1965-1966 Chrysler 300 and 1966 Dodge Charger (All) — see the Buyer's Guide tab for the full list.
- Cast-iron housing: the cylinder housing is built to match the casting material of the original part for similar performance.
- EPDM rubber components: all rubber parts use a high-quality EPDM compound for resistance to glycol-based brake fluid.
- 100% new: made entirely of new materials, not remanufactured.
- Specifications: 1-inch bore, single outlet with a 7/16-24 rearward outlet size, and an included reservoir; no sensor and no mounting hardware included. Made to meet rigorous SAE International standards.
Signs the master cylinder may need replacing include a pedal that slowly sinks under steady foot pressure, a soft or spongy pedal, or brake fluid loss with no external leak — diagnose the cause before replacing, since these signs can have other sources. Mounting hardware is not included; consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: Taiwan.
