Dorman - First Stop Brake Master Cylinder P/N:M390365

Convert brake-pedal effort into the hydraulic pressure that feeds the brake circuits with the Dorman - First Stop Brake Master Cylinder M390365. It drops in as a direct-fit replacement for the 1995-1997 Toyota Land Cruiser and 1996-1997 Lexus LX450 (All engines), and is precision-engineered to match the design, function, and performance of the original unit on those applications.

• Aluminum housing: the cylinder housing is cast to match the casting material of the original part for similar performance.
• Glycol-fluid-resistant rubber: all rubber components use a high-quality EPDM compound for resistance to glycol-based brake fluid.
• 100% new: built entirely of new materials — not remanufactured — and made to meet SAE International standards.
• As-supplied hardware: includes a reservoir and sensor, with two outlets, a 1 in bore, and M10 x 1.0 outlet threads.

The master cylinder pressurizes brake fluid when you press the pedal and distributes it to the brake circuits. A slowly sinking pedal, a soft or spongy pedal, or unexplained fluid loss can be signs this part may need replacing; these symptoms can have other causes, so diagnose the system first — if the master cylinder is the cause, this M390365 replaces it. Mounting hardware is not included; consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: Taiwan.
