Parts for your 1998 Mitsubishi Lancer-Brake wheel cylinders

1998 Mitsubishi Lancer brake wheel cylinders: what they do and when to replace them

Based on technical references including the Mitsubishi Lancer CE (1996–2003) workshop manual – Brake section, the Mitsubishi ASA electronic parts catalogue for CE Lancer, and general repair data from the Haynes Mitsubishi Lancer manual (1991–2012), brake wheel cylinders are used on most 1998 Mitsubishi Lancer models fitted with rear drum brakes (typical for 1.5/1.8 GL/GLi/GLX trims in Australia and New Zealand). Performance variants with rear disc brakes (such as GSR or Evolution) use rear callipers instead and therefore do not have brake wheel cylinders.

For 1998 Lancers equipped with rear drums, the brake wheel cylinder is the small hydraulic unit that pushes the shoe linings out against the drum when the brake pedal is pressed. It’s simple, reliable, and—because it sits low and out back—prone to a bit of grime and moisture over time. That’s why keeping an eye on it during regular servicing pays off.

The purpose is straightforward: turn hydraulic pressure into sideways movement of the shoes. If a wheel cylinder leaks, the brake pedal can feel spongy, stopping distances grow, and brake fluid can soak the shoes, hurting rear braking and sometimes the handbrake’s hold. Tell‑tale signs include dampness or fluid trails at the bottom of the backing plate, weeping under the dust boots, uneven rear braking, or a gradual drop in fluid level in the reservoir.

Good servicing habits for a 1998 Lancer with drum rears include:

• Inspect the rear wheel cylinders at each brake service (every 10,000–15,000 kilometres or annually).
• Lift the dust boots to check for seepage, any fluid means replacement is due.
• Replace wheel cylinders in axle pairs to maintain even braking.
• Renew contaminated shoes and clean the drum if there’s been a leak.
• Flush brake fluid every 2 years, use the DOT grade specified on the master cylinder cap (DOT 3 or DOT 4). Don’t mix old, unknown fluid.
• After fitting new cylinders, bleed the system properly and adjust the drum shoes so the pedal height and handbrake feel are spot on.

Quality cylinders, fresh fluid, and correct adjustment keep the Lancer’s brake feel consistent and confidence high. For trims with rear disc brakes, there’s no wheel cylinder to worry about—attention shifts to calliper slides, seals, and pads instead. If unsure which rear setup is on the car, a quick look behind the rear wheel or a check against the vehicle ID in the parts catalogue settles it fast.

Popular questions about 1998 Mitsubishi Lancer brake wheel cylinders

Do all 1998 Lancers have brake wheel cylinders?
Most non-performance 1998 CE Lancers in Australia and New Zealand run rear drum brakes with wheel cylinders. Models with rear disc brakes (e.g., GSR/Evolution) don’t use wheel cylinders at the back—they use callipers. A glance behind the rear wheel will show a drum (cylinders fitted) or a disc and calliper (no cylinders).

How often should wheel cylinders be replaced?
There’s no fixed interval, they’re replaced on condition. During routine services, the technician checks for weeping under the dust boots, fluid trails, or sticky pistons. If there’s any seepage or the pedal feel is soft and a leak is found, both rear cylinders should be replaced, shoes renewed if contaminated, and the fluid flushed.

What are the symptoms of a failing wheel cylinder on a Lancer?
Common signs are a soft or sinking brake pedal, fluid stains on the inside of the rear backing plate or drum, uneven rear braking, rear lock-up in the wet due to contamination, and a slowly dropping fluid level in the reservoir. Pull the drum and check—any wetness around the cylinder means it’s time for new parts.
