Parts for your 2000 Mitsubishi Pajero-Brake master cylinder

2000 Mitsubishi Pajero Brake Master Cylinder

Technical sources confirm the 2000 Mitsubishi Pajero is fitted with a brake master cylinder and relies on it for normal operation of its hydraulic braking system. The Mitsubishi Pajero/Montero V60/V70 Series factory service manual (1999–2002 coverage), the Mitsubishi ASA electronic parts catalogue (EPC) listing “Master Cylinder, Brake” for NM-series Pajero variants with and without ABS, and aftermarket service references such as the Haynes Pajero/Montero/Shogun 1997–2007 manual all document the master cylinder as an installed component. It’s a tandem (dual-circuit) unit mounted to the brake booster with an integrated fluid reservoir and low-fluid switch.

On the 2000 Pajero, the master cylinder’s job is simple but critical: convert pedal effort into hydraulic pressure, sending it down two separate circuits for safety. Paired with the vacuum booster and ABS modulator, it delivers consistent pedal feel and balanced braking front to rear. If the master cylinder is tired, the pedal can feel spongy or slowly sink at the lights, stopping distances grow, and the brake warning lamp may flick on due to low fluid.

Servicing advice for Pajero owners and fleets in Aussie and Kiwi conditions is straightforward. Brake fluid is hygroscopic, so flush with fresh DOT 4 (meeting FMVSS 116) every 24 months or around 40,000 km unless the service schedule for the specific variant says otherwise. Avoid silicone DOT 5. Inspect the reservoir for dark or cloudy fluid, check for dampness where the master meets the booster, and look for weeping at the line ports and reservoir grommets. When replacing the master cylinder, a quality OEM-equivalent unit and new grommets are worth it.

• Bench-bleed the new cylinder before installation to purge trapped air.
• Use proper flare-nut spanners to avoid chewing the brake-line fittings.
• Set pedal pushrod free play to spec, an incorrect adjustment can cause dragging brakes or long travel.
• Bleed the system per the workshop sequence, some ABS variants bleed conventionally, but always follow the manual. A road test that activates ABS on a safe surface helps clear any residual air in the modulator.
• After fitting, recheck for leaks, confirm a firm pedal, and ensure the ABS and brake warning lamps are out.

What fluid should a 2000 Pajero use, and how often is it changed?

Most 2000 Pajero variants specify DOT 3 or DOT 4, DOT 4 is commonly used in Australia and New Zealand for its higher boiling point. Replace every 2 years or around 40,000 km to protect the master cylinder, ABS valves, and calipers from corrosion and moisture-related fade. Always use fresh, sealed fluid.

How can someone tell the master cylinder is failing?

Classic signs include a pedal that slowly sinks under steady pressure, a soft or spongy feel that returns after pumping, visible leaks at the cylinder or reservoir grommets, dark/contaminated fluid, and a brake warning lamp from low fluid. Other issues like warped rotors won’t mimic a sinking pedal.

Does ABS make replacement harder on the 2000 Pajero?

Most NM-series Pajeros can be bled conventionally after bench-bleeding the new master cylinder. Some workshops use a scan tool to cycle ABS valves, but it’s often not mandatory. Follow the factory procedure, then perform a careful road test to confirm a firm pedal and proper ABS operation.
