- Precise replacement: the aluminum cylinder housing is constructed 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.
- 100% new: made entirely from new materials for quality and safety.
- Strict specifications: made to meet rigorous SAE International standards.
The reservoir and sensor are included. The cylinder has a 1.25 in bore and 3 outlets: an M18 x 1.5 rearward outlet and secondary outlet threads of 9/16-18 and 3/8-24. Mounting hardware is not included. Country of origin: China.
A soft or sinking brake pedal, or fluid seeping from the master cylinder, are signs it may need replacing. If a worn master cylinder is the cause, this unit replaces it. Follow the vehicle service information when bleeding the new cylinder and the brake system.
