Parts for your 1999 Mitsubishi Lancer-Brake master cylinder

1999 Mitsubishi Lancer Brake Master Cylinder

Technical references confirm the 1999 Mitsubishi Lancer is fitted with a brake master cylinder. The Mitsubishi Lancer CE (1996–2003) Workshop Manual, Group 35A – Brakes, details a tandem hydraulic master cylinder mounted to a vacuum brake booster. The Mitsubishi ASA electronic parts catalogue for MY1999 Lancer also lists the master cylinder assembly and service components. Additionally, the Haynes Mitsubishi Lancer & Mirage 1997–2005 manual covers master cylinder inspection, removal and bleeding procedures for these models. So yes, a brake master cylinder is absolutely used and relevant on a 1999 Mitsubishi Lancer.

For a 1999 Mitsubishi Lancer, the brake master cylinder is the heart of the hydraulic braking system. When the driver presses the pedal, the master cylinder converts that foot pressure into hydraulic force, pushing brake fluid through the lines to clamp the front and rear brakes. The Lancer uses a tandem (dual-circuit) design for safety, so if one circuit loses pressure, the other can still provide some stopping power.

As part of routine servicing, it’s smart to keep the master cylinder and fluid in top nick. Brake fluid is hygroscopic, so moisture build-up can corrode internals and soften the pedal. A fluid flush every 2 years (or about 40,000 km) with the specified DOT 3 or DOT 4 fluid is a solid plan for Aussie and Kiwi conditions. Always keep the reservoir cap clean, don’t overfill, and use fresh, unopened fluid.

Signs the Lancer’s master cylinder may be on the way out include a spongy pedal, the pedal slowly sinking at the lights, fluid weeping where the master meets the booster, contaminated or dark fluid that returns quickly after a flush, or a brake warning lamp. If these show up, have it checked straight away.

Replacing the master cylinder isn’t a hard job for a competent DIYer, but it does need care. Key tips:

• Bench-bleed the new cylinder before fitting to purge internal air.
• Protect paintwork—brake fluid can damage the bonnet and guards.
• Inspect the booster for fluid ingress, replace the booster check valve grommet if perished.
• Confirm pushrod free play per the workshop manual to ensure the brakes don’t drag.
• Bleed the system thoroughly after installation. Follow the service manual sequence (often the wheel furthest from the master first) and use clear tubing to watch for bubbles.
• Avoid mixing DOT 5 silicone with DOT 3/4. Stick with the spec on the cap or owner’s manual.

With the right fluid, correct bleeding, and occasional inspections for leaks and pedal feel, the Lancer’s master cylinder will deliver reliable, confidence-inspiring stops for years.

Popular questions about 1999 Mitsubishi Lancer brake master cylinders

What brake fluid should be used in a 1999 Mitsubishi Lancer?
Most 1999 Lancers specify DOT 3 or DOT 4 glycol-based brake fluid. In Australia and New Zealand, DOT 4 is commonly used for its higher boiling point. Don’t mix silicone DOT 5 with DOT 3/4. If unsure, check the reservoir cap or the owner’s manual.

How can someone tell if the master cylinder is failing on a 1999 Lancer?
Typical clues are a soft or sinking pedal, fluid leaks at the master or booster, a brake warning lamp, or brakes that don’t firm up after a proper bleed. If the pedal slowly drops with steady pressure and there are no external leaks, internal bypassing in the master cylinder is likely.

Is bench bleeding really necessary when replacing the master cylinder?
Yes. Bench bleeding removes trapped air from the new unit before it goes on the car, making final system bleeding quicker and preventing a persistently spongy pedal. Skipping this step often leads to repeat bleeding and frustrating pedal feel.
