Parts for your 2006 Mitsubishi Lancer-Cluth slave cylinder

2006 Mitsubishi Lancer cluth-slave-cylinder: what it does and when to replace it

Referencing the Mitsubishi Motors CH/CS Lancer Workshop Manual (2003–2007) and common parts catalogues used by Aussie and Kiwi workshops, the 2006 Mitsubishi Lancer with a manual gearbox uses a hydraulic clutch system with both a master cylinder and an external cluth-slave-cylinder on the gearbox bellhousing. Automatic models don’t have a manual clutch, so a cluth-slave-cylinder isn’t fitted or relevant on those variants.

On manual 2006 Lancers, the cluth-slave-cylinder is the hard-working bit that turns pedal pressure into movement at the clutch fork, letting the driver shift gears smoothly. It uses brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual) to push a piston and rod each time the clutch pedal is pressed. When it’s healthy, gear changes feel clean and consistent, when it’s tired, the pedal may feel soft, the gears may baulk, or you’ll spot fluid weeping around the cylinder or down the bellhousing.

As part of routine servicing, it’s smart to check the cluth-slave-cylinder for leaks, a damaged dust boot, and smooth operation. A quick look every service and a fluid flush every 2–3 years (or roughly 40,000–50,000 kilometres) helps keep the hydraulics crisp and the seals happy. Brake fluid is hygroscopic, so fresh fluid wards off internal corrosion and spongy pedal feel.

If replacement’s on the cards, it’s a straightforward driveway job for many owners, but attention to detail matters. Use quality fluid, protect paintwork (brake fluid is nasty on paint), and crack the bleed nipple with a proper ring spanner. After fitting the new cluth-slave-cylinder, bleed the system until bubbles are gone and pedal feel is firm and consistent. If the pedal still sinks or feels airy, check for upstream issues at the clutch master cylinder and inspect hoses for pinhole leaks or swelling.

• Watch for: low fluid in the reservoir, dark/contaminated fluid, clutch drag at a stop, difficulty selecting reverse/first, and wetness around the slave’s boot.
• Good practice: replace the slave and flexible hose together if they’re both ageing, and consider doing the master cylinder if the pedal feel remains inconsistent after a proper bleed.

FAQs

Does a 2006 Mitsubishi Lancer have a cluth-slave-cylinder?
Yes, if it’s a manual. The CH/CS Lancer manual-transmission models use a hydraulic clutch with a cluth-slave-cylinder. Automatic versions don’t use one, as they don’t have a manual clutch system.

How often should the cluth-slave-cylinder fluid be changed?
Plan on flushing the clutch hydraulic fluid every 2–3 years or around 40,000–50,000 kilometres. Fresh DOT 3 or DOT 4 fluid (as per the owner’s manual) keeps pedal feel sharp and protects internal seals from moisture-related wear.

Can it be driven with a failing cluth-slave-cylinder?
It might limp along, but it’s risky. A failing slave can lose pressure suddenly, leaving the clutch stuck engaged and making gear changes hard or impossible. Best to sort it promptly to avoid getting stranded and to prevent extra wear on the gearbox and clutch.
