Turn pedal effort into hydraulic brake pressure with the Dorman First Stop Brake Master Cylinder M49201, a new unit engineered to match the design, function and performance of the original master cylinder. It fits several Buick models, among them the 1963-1966 Buick Electra, 1963-1966 Buick LeSabre and 1964-1966 Buick Riviera. See the Buyer's Guide tab for the full list.
The master cylinder converts force from the brake pedal into hydraulic pressure that travels through the brake lines. A spongy or slowly sinking pedal, or fluid leaking at the cylinder, are signs it may need replacing. Diagnose the brake system before replacing it.
- Precise replacement: the cylinder housing is cast iron, built to match the casting material of the original part for similar performance.
- Durable design: every rubber component uses a high-quality EPDM compound that resists glycol-based brake fluid.
