Turn brake-pedal force into the hydraulic pressure that operates your braking system with the Dorman - First Stop Brake Master Cylinder M390162. It installs as a direct-fit replacement for the 1994-1997 Honda Passport, 1993-1994 Isuzu Amigo, 1993-1995 Isuzu Pickup, and 1993-1997 Isuzu Rodeo (All engines). Built entirely from new materials — not remanufactured — it's engineered to match the design, function, and performance of the master cylinder it replaces.
Made to meet rigorous SAE International standards. A sinking pedal, loss of hydraulic pressure, or fluid seepage at the cylinder are signs this part may need replacing — diagnose the cause first, and if the master cylinder is at fault, this replaces it. Country of origin: China.
