Dorman - First Stop Brake Master Cylinder P/N:M39502

Convert brake-pedal effort into hydraulic pressure across both brake circuits with the Dorman - First Stop Brake Master Cylinder M39502. Engineered to drop in like the original on these applications, it installs as a direct-fit replacement for the 1980-1984 Toyota Cressida [All] and the 1979-1985 Toyota Pickup [All].

• Cast iron housing: the cylinder body is constructed to match the casting material of the original part for similar performance.
• Two outlets: dual outlets with a 0.875 in bore and M10 x 1.0 outlet threads (1 mm thread pitch).
• EPDM seals: rubber components 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.

The master cylinder pressurizes brake fluid when you press the pedal, sending it to the brake circuits. A reservoir is included; a sensor is not, and mounting hardware is not included — consult the vehicle service information for the correct fasteners and whether they may be reused. Signs this part may need replacing include a sinking or spongy pedal or fluid loss; diagnose the cause before replacing. Country of origin: China. Manufacturer part number M39502.
