Description

Convert brake pedal effort into hydraulic pressure for your truck's brakes with this Dorman brake master cylinder, part number M630948 from the Dorman - First Stop line. It is a direct-fit replacement for the 2013-2016 Ford F-450 Super Duty and 2013-2016 Ford F-550 Super Duty (All engines), precision-engineered to mirror the original unit's design, function and performance on those trucks.

Precise replacement: the cylinder housing is cast iron, constructed to match the casting material of the original part and intended to deliver similar performance.
Durable design: every rubber component is made from a high-quality EPDM compound that resists glycol-based brake fluid.
100% new: made entirely of new, high-quality materials.
Strict specifications: made to meet rigorous SAE International standards.

Specifications: 1.5 in. bore diameter · single reservoir (included) · sensor included · 3 outlets · rearward outlet sizes M14x1.5 and M12x1.0 · secondary outlet thread M12x1.5. Mounting hardware is not included. Country of origin: Taiwan.

This Dorman master cylinder ships with its reservoir and sensor. Signs a master cylinder may need replacing include a brake pedal that feels soft or slowly sinks, fluid seeping from the unit, or a reservoir level that keeps dropping. Diagnose the cause before replacing, because other brake components can produce similar symptoms. Bleed the master cylinder and brake system as directed by the vehicle service information.
