Dorman - First Stop Drum Brake Wheel Cylinder P/N:W37405

Keep hydraulic pressure flowing to your rear drum brake shoes with the Dorman First Stop Drum Brake Wheel Cylinder (W37405). Mounted at the rear drum, a wheel cylinder converts brake-line pressure into the mechanical push that forces the shoes outward against the drum. This direct-replacement unit is engineered to match the original wheel cylinder's fit, function and performance, and it drops in on the 1977-1978 Nissan 280Z, 1981 Nissan 810, 1982-1984 Nissan Maxima, and 1984-1985 Nissan 200SX (All engines).

• EPDM rubber cups and boots: built with high-quality EPDM rubber cups and boots for long-lasting performance.
• Surface-tested bore: the wheel cylinder bore is surface-tested to provide an optimum sealing surface for the pressure cups.
• Bleeder screw included: ships with a bleeder screw; a bleeder screw cap is not included.
• Key specs: aluminum body with a 0.875 in bore and an M10 x 1.0 (10 mm) inlet thread.
