Dorman precision-engineers this master cylinder to match the original unit's design, function and performance on the vehicles it is cataloged for. It is built from new, high-quality materials for a safe, durable replacement.
- Precise replacement: the cylinder housing is constructed to match the casting material of the original part for similar performance.
- Durable design: all rubber components use a high-quality EPDM compound that resists glycol-based brake fluid.
- 100% new: made entirely from new materials for quality and safety.
- Strict specifications: made to meet rigorous SAE International standards.
Signs a master cylinder may need replacing include a soft or spongy brake pedal, a pedal that slowly sinks under steady pressure, or brake fluid seeping from the unit. Other brake components can cause these symptoms, so diagnose the system first. If the master cylinder is at fault, this unit replaces it. Bench-bleed the new master cylinder before installation, then bleed the brake system afterward following the vehicle service information. See the "Vehicles it fits" section for the full list of applications.
