Dorman - First Stop Brake Master Cylinder P/N:M630694

Turn brake-pedal effort into the hydraulic pressure that operates your brakes with the Dorman - First Stop Brake Master Cylinder (M630694). It drops in as a direct-fit replacement for the 2011-2019 Ford Fiesta [All], precision-engineered to match the design, function, and performance of the original master cylinder on those applications.

Features:

• 100% new: made entirely of new materials, not remanufactured.
• Aluminum housing: built to match the casting material of the original part for similar performance.
• Durable design: all rubber components use a high-quality EPDM compound for resistance to glycol-based brake fluid.
• Built to spec: made to meet rigorous SAE International standards.

A master cylinder converts the force applied at the brake pedal into hydraulic pressure sent to the brake circuits; this unit has two outlets and a 0.813 in bore diameter, with the rearward/secondary outlet sized M12 x 1.0 and a 1 mm primary outlet thread pitch. The reservoir and a sensor are included; mounting hardware is not included, so consult the vehicle service information for the correct fasteners and whether they may be reused. Signs the original may need replacing include a pedal that slowly sinks under steady pressure, a low or spongy pedal, or brake fluid loss — diagnose the cause first, and if a failed master cylinder is the culprit, this replaces it. Country of origin: Taiwan.
