Dorman - First Stop Brake Master Cylinder P/N:M630001

Convert brake-pedal effort into the hydraulic pressure your braking system relies on with the Dorman - First Stop Brake Master Cylinder M630001.

• 100% new: Made entirely of new materials, not remanufactured, and built to meet SAE International standards.
• Key specs: 1.125 in bore, two outlets, rearward outlet M12 x 1.0, secondary outlet thread M10 x 1.0, primary outlet thread pitch 1 mm. Reservoir and sensor included.
