Parts for your 2005 Mitsubishi Pajero-Clutch master cylinder

2005 Mitsubishi Pajero Clutch Master Cylinder

Based on the Mitsubishi Pajero NM/NP Workshop Manual (clutch section), the Mitsubishi ASA Electronic Parts Catalogue (Group 21 – Clutch), and general repair guides such as the Haynes Pajero/Montero 1997–2009 manual, the 2005 Mitsubishi Pajero with a manual gearbox uses a hydraulic clutch system with a clutch master cylinder. It isn’t fitted to automatic models, which don’t require a hydraulic clutch circuit.

The clutch master cylinder’s job is simple but critical: it turns pedal effort into hydraulic pressure. Pressing the pedal pushes a piston and seals inside the master, sending brake fluid through a line to the slave cylinder on the gearbox. That movement disengages the clutch so gears can be selected smoothly. On right-hand-drive Pajeros in Australia and New Zealand, the master cylinder is mounted on the firewall ahead of the driver, with a small fluid reservoir on top. It uses brake fluid—typically DOT 3 or DOT 4—always check the cap and the workshop spec.

As part of regular servicing, it’s smart to check the reservoir level and fluid colour, inspect for dampness around the firewall and pedal pushrod, and make sure pedal feel is firm and consistent. A fluid flush every 24 months (or around 40,000 km) helps keep internal seals happy and reduces corrosion in the line and slave. Keep brake fluid off paint—have rags and water handy.

Signs it’s time for attention or replacement include:

• Pedal that slowly sinks or feels spongy
• Gear selection getting notchy, especially into first or reverse
• Visible leaks at the master, hose, or slave, or low/dirty fluid

When replacing the master cylinder, bench-bleed it before installation, then bleed at the slave cylinder nipple (keep the reservoir topped up). A 10 mm spanner and clear hose make the job tidier. Many techs replace the slave at the same time, plus the flexible hose, to avoid chasing one weak link after another. Expect roughly 1–2 hours for a straightforward job, depending on access and corrosion on fittings.

Choosing a quality OE or well-known aftermarket unit matters, better internal seals and bore finish deliver a firmer, longer-lasting pedal. If the Pajero is used for towing or off-road work, keep an extra eye on fluid condition and pedal feel—heat and dust are not kind to hydraulics. Automatic models don’t have or need a clutch master cylinder, so this advice applies only to manual-trans Pajeros.

Does a 2005 Mitsubishi Pajero have a clutch master cylinder?

Yes—on manual transmission models. The hydraulic system uses a master cylinder on the firewall and a slave cylinder on the bell housing. Automatic versions don’t have a clutch system, so no master cylinder is fitted.

What fluid should go in the Pajero’s clutch master cylinder?

Use brake fluid specified on the reservoir cap—commonly DOT 3 or DOT 4. Don’t mix types unless the spec allows it, and avoid spilling fluid on paint. Replace fluid every two years for best pedal feel and seal life.

How do you bleed the clutch on a 2005 Pajero?

Top the reservoir, attach a clear hose to the slave’s bleeder, and have a helper pump and hold the pedal while you crack the bleeder to release air and fluid. Close the nipple, repeat until air-free, and keep the reservoir topped up. Bench-bleeding a new master first makes the final bleed quicker.
