Parts for your 1998 Mitsubishi Pajero-Brake wheel cylinders

1998 Mitsubishi Pajero brake wheel cylinders – what they do and when to replace them

Technical sources including the Mitsubishi Pajero NL (1997–1999) workshop manual (Brakes section), the Mitsubishi ASA electronic parts catalogue for NL models, and general repair guides such as the Haynes Pajero/Montero 1983–1999, confirm that many 1998 Mitsubishi Pajero variants in Australia and New Zealand run rear drum brakes with hydraulic brake wheel cylinders. Some higher-spec trims were built with rear disc brakes, those versions don’t use wheel cylinders. For drum‑rear models, brake wheel cylinders are absolutely relevant service items.

On a 1998 Pajero with rear drums, the brake wheel cylinder sits at the top of each rear backing plate. When the brake pedal’s pressed, fluid pressure pushes the small pistons outwards to spread the shoes against the drum. Simple, robust and effective for a heavy-duty 4x4, especially in muddy or sandy conditions where drums can be less exposed than calipers.

Because the cylinders live down near the road grime, they’re worth checking at every service. Look for perished rubber boots, weeping fluid, or shoe linings contaminated with brake fluid. Any leak means it’s time for replacement or a quality rebuild. Most workshops will renew both rear wheel cylinders as a pair to keep braking balance even, and they’ll recommend inspecting the shoes, drums and hardware at the same time.

Fresh brake fluid matters too. The factory spec is typically DOT 3, with DOT 4 commonly used in local workshops, either can be suitable—stick with what’s on the reservoir cap or in the service manual, and don’t mix types. A full fluid flush every two years helps keep internal corrosion at bay and maintains pedal feel.

When replacing wheel cylinders on a Pajero, it pays to:

• Inspect and, if needed, replace the shoe set, springs and adjusters.
• Clean the backing plate and lightly lubricate shoe contact points with the correct brake grease (not on friction or hydraulic surfaces).
• Bleed the system carefully and verify a firm pedal before driving.

Done right, new wheel cylinders restore even, predictable rear braking and keep this NL Pajero stopping straight on bitumen, gravel, and beach runs alike.

Popular questions

Does a 1998 Pajero definitely have brake wheel cylinders?
Most 1998 NL Pajeros in AU/NZ with rear drum brakes do. A few higher-spec variants have rear discs, which don’t use wheel cylinders. A quick look behind the rear wheel will tell the story: a drum means a wheel cylinder, a visible caliper means discs and no wheel cylinder.

What are the signs a Pajero’s wheel cylinder is failing?
Tell-tales include a soft or sinking pedal, the vehicle pulling to one side under brakes, dampness around the rear backing plate, or brake fluid on the inside of the drum. Any of these warrants immediate inspection—brake fluid leaks can quickly reduce stopping power.

Should both rear wheel cylinders be replaced at the same time?
It’s good practice. Replacing them as a pair helps keep braking even left-to-right. Many techs will also recommend new rear shoes and a drum clean or machine if wear or glazing is present, followed by a full fluid bleed.
