Description

Turn brake-pedal effort into hydraulic pressure with the Dorman - First Stop Brake Master Cylinder M39848. It drops in as a direct-fit replacement for the 1990-1994 Subaru Legacy (All engines), where the master cylinder pressurizes brake fluid and sends it out to the brake circuits. Built to the design, function, and performance of the factory unit for this application, it's a 100% new part — not remanufactured.

100% new construction: made entirely of new materials, not rebuilt, and made to meet SAE International standards.
Aluminum housing: the cylinder housing is constructed to match the casting material of the original part for similar performance.
Fluid-resistant seals: all rubber components use a high-quality EPDM compound for resistance to glycol-based brake fluid.
Specs: 1 in bore, 3 outlets, rearward outlet M10 x 1.0; reservoir and sensor included.

Mounting hardware is not included — consult the vehicle service information for the correct fasteners and whether they may be reused. Signs the original master cylinder may need replacing include a pedal that slowly sinks under steady pressure or feels spongy; diagnose the cause before replacing, since these symptoms can have other sources.

Manufacturer part number M39848. Country of origin: Taiwan.
