$232.99
Build the hydraulic pressure that pushes fluid to every wheel with the Dorman - First Stop Brake Master Cylinder M39988. It installs as a direct-fit replacement for the 1992 Isuzu Amigo, the 1990-1993 Isuzu Pickup, and the 1991-1993 Isuzu Rodeo (All engines). When you press the pedal, the master cylinder converts pedal force into hydraulic pressure and sends brake fluid through its two outlets to the brake circuits.
