What does a brake master cylinder do?
It converts force from the brake pedal into hydraulic pressure. That pressure sends brake fluid through the brake lines to apply the brakes at the wheels.
What are the key specifications of M18000?
It has a cast-iron housing, a 1 in. bore diameter and one outlet with a 1/2-20 rearward outlet size. Its rubber components use an EPDM compound that resists glycol-based brake fluid.
What comes in the box?
The package contains the master cylinder with its reservoir. Mounting hardware and a sensor are not included.
What should I know about installing it?
Master cylinders are typically bench-bled before installation, and the brake system is bled afterward. Consult the vehicle service information for the correct fasteners, procedure and brake fluid.
