2017 Mitsubishi Lancer Clutch Master Cylinder

Based on technical sources, a clutch master cylinder is used on 2017 Mitsubishi Lancer models equipped with the 5‑speed manual transmission, and is not present on Lancer models fitted with the CVT automatic. References include:

• Mitsubishi Motors Lancer (CY/CF platform, 2008–2017) Service Manual, Group 21 – Clutch, which details a hydraulic clutch system with a clutch master cylinder on manual variants.
• Mitsubishi ASA/EPC (Electronic Parts Catalogue) listing “Cylinder Assy, Clutch Master” for 2017 Lancer manual models.
• Professional repair databases (e.g., ALLDATA, Mitchell1) and mainstream parts catalogues (Aisin, Exedy) that specify master cylinder servicing and replacement for 2017 Lancer manuals.

On a manual 2017 Mitsubishi Lancer, the clutch master cylinder is the heart of the hydraulic clutch system. Pressing the clutch pedal pushes a piston inside the master, building hydraulic pressure and sending fluid down to the slave cylinder to disengage the clutch. It’s what makes gear changes smooth and predictable, and it’s designed to work quietly under the bonnet for years with the right care.

For servicing, the master cylinder shares the same fluid type as brake systems—DOT 3 or DOT 4, as marked on the reservoir cap. Fluid absorbs moisture over time, so a clutch fluid flush every 2 years or around 40,000 kilometres is smart maintenance for Aussie and Kiwi conditions. Fresh fluid helps keep internal seals healthy and pedal feel consistent. When servicing, protecting paintwork is a must—spilled brake/clutch fluid is harsh on finishes—so rags and a catch bottle under the engine bay and pedal area go a long way.

Typical signs the Lancer’s master cylinder needs attention include a soft or sinking pedal, difficulty selecting gears (especially reverse and first), clutch engagement right off the floor, or fluid weeping at the firewall or above the pedal. If those show up, replacement is usually the reliable fix. Best practice is to bench‑bleed the new master before fitment, then bleed the system at the slave cylinder. Inspect the pushrod and pedal clevis for wear and set the pedal free play to spec to keep the bite point consistent.

Quality replacement parts from known brands and a clean bleed make all the difference. For Lancers running the CVT automatic, there’s no clutch pedal and no clutch hydraulic circuit—so there’s no clutch master cylinder to service on those vehicles.

• Key tips:
  • Use the fluid grade shown on the cap (commonly DOT 3).
  • Flush every 2 years to reduce moisture and corrosion.
  • Check for leaks at the firewall and pedal box if the pedal feels spongy.

Popular questions

Does every 2017 Lancer have a clutch master cylinder?
No. Only the 5‑speed manual models use a clutch master cylinder. Lancers with the CVT automatic don’t have a clutch pedal or hydraulic clutch circuit, so there’s no master cylinder fitted.

What fluid should be used in the 2017 Lancer’s clutch master cylinder?
The system uses brake‑type hydraulic fluid—DOT 3 or DOT 4 as specified on the reservoir cap. Many Lancer manuals specify DOT 3. Mixing types isn’t recommended, stick with the grade listed for the vehicle and keep it clean.

How can an owner tell if the clutch master cylinder is failing?
Common clues are a soft or sinking pedal, difficulty getting into gear, a clutch that grabs low, or dampness around the firewall or above the pedal. If those symptoms appear, inspection and likely replacement of the master—and a full bleed—are the usual remedy.
