Dorman - First Stop Brake Master Cylinder P/N:M39465
$118.99
The brake master cylinder converts your brake-pedal effort into the hydraulic pressure that operates the vehicle's brakes. The Dorman - First Stop Brake Master Cylinder M39465 drops in as a direct-fit replacement for the 1983-1984 Mazda B2000 [All], built completely from new materials rather than remanufactured.
- Cast iron housing: the cylinder body uses cast iron and is constructed to match the casting material of the original part for similar performance.
- Two outlets: a dual-outlet design with a 0.813 in bore and an M10 x 1.25 rearward outlet.
- EPDM rubber components: all rubber parts use a high-quality EPDM compound for resistance to glycol-based brake fluid.
- 100% new: made entirely of new materials, not remanufactured, and built to meet rigorous SAE International standards.
Dorman engineered this unit to reproduce the original master cylinder's design, function, and performance on the specified applications. Note that a reservoir, sensor, and mounting hardware are not included; consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: Taiwan.
