Detailed Description

Cardone part number 13-3113 is a new brake master cylinder for the 2003-2004 Mitsubishi Outlander. It is engineered to match original equipment performance using O.E.-quality seals and cups, with bore surfaces finished to critical specifications for consistent hydraulic sealing. The aluminum housing and protective coating help support long-term durability in everyday driving conditions.

This brake master cylinder is a direct-fit hydraulic replacement for Outlander brake service where the original unit has internal bypass, leakage, or pedal inconsistency. The reservoir is included, and the unit is endurance-tested to help confirm fit, function, and reliable operation before installation.

What It Helps Fix

• Low or spongy brake pedal feel
• Internal master cylinder bypass
• Brake fluid leakage from the master cylinder
• Pedal drop during brake pressure testing
• Hydraulic pressure loss affecting braking response

Installation Notes and Tips

Use the brake fluid specified by the original equipment manufacturer and only fresh fluid from a sealed container. Before installation, bench bleed the master cylinder and follow the correct bleeding procedure for the brake system. If the pedal remains low after replacement, inspect the booster, calipers, wheel cylinders, hoses, and fluid condition for contamination or restriction.

For diagnosis, plug the master cylinder ports and apply pedal pressure; if the pedal drops, the master cylinder is bypassing. If the pedal holds firm, the issue is elsewhere in the brake system. Check the booster push rod seal if fluid has entered the booster area.

Quality Assurance

Cardone designs its new master cylinders to match O.E. performance using reverse-engineering experience from brake product remanufacturing. This unit is endurance-tested, and its seals are temperature-cycled to help verify reliable operation under a wide range of driving temperatures.
