Brake Master Cylinder MK429255 For MITSUBISHI CANTER FE84/FE85 4M42 — 1.1/4" Bore Direct Replacement
MK429255 Brake Master Cylinder for MITSUBISHI FUSO CANTER FE84 FE85 4M42 3.0L Diesel — Direct Replacement
Product Overview
The Brake Master Cylinder with OEM number MK429255 is a verified direct-fit replacement for MITSUBISHI FUSO CANTER light-duty trucks, specifically the FE84 and FE85 models (2007–2013) equipped with the 4M42 3.0L 4-cylinder common rail diesel engine (4P10 series). It is also compatible with FE83D chassis and various FE8_ chassis from the 2005 model year onward.
The brake master cylinder is the heart of the vehicle's hydraulic braking system. Mounted on the firewall directly in front of the driver, it converts the mechanical force applied to the brake pedal into hydraulic pressure, which is then distributed through separate brake circuits to the calipers or wheel cylinders to stop the vehicle efficiently and safely. It features a dual-piston design (tandem master cylinder). If one hydraulic circuit fails due to a leak, the other circuit remains functional, providing a critical safety margin and allowing the vehicle to be brought to a controlled stop.
Important Fitment Note: This master cylinder (MK429255) is typically designed for vehicles without an Anti-lock Braking System (ABS). If your CANTER is equipped with ABS (indicated by a hydraulic control unit near the master cylinder), a different master cylinder part number may be required. Always verify your vehicle's original equipment before ordering.

Common Failure Patterns
- Sinking / Spongy Brake Pedal: Pedal slowly sinks to the floor under steady pressure — indicates internal piston seal leakage
- Brake Warning Light Illumination: May indicate low brake fluid level from external leak or excessive pedal travel from internal failure
- Visible External Leak: Brake fluid residue on the firewall behind the master cylinder
- Pedal Pumping Required: Hard pedal that only firms up after pumping indicates worn seals failing to maintain residual pressure
- Contaminated Brake Fluid: Discolored fluid or debris in reservoir may indicate internal seal degradation

Installation & Maintenance
IMPORTANT: Brake master cylinder replacement is a safety-critical repair involving high hydraulic pressure. Professional installation by a qualified mechanic is essential. Improper bleeding or installation can compromise braking performance and lead to brake failure.
Professional Installation Guide
- Disconnect battery negative terminal
- Drain or siphon old brake fluid from the reservoir
- Remove electrical connector from brake fluid level sensor (if equipped)
- Disconnect brake lines from the master cylinder ports using a flare nut wrench
- Remove the two mounting nuts securing the master cylinder
- Carefully remove old master cylinder
- CRITICAL: Bench-bleed the new master cylinder before installation
- Clean the mounting surface on the brake booster
- Install new master cylinder with new gasket or O-ring
- Torque mounting nuts to 15–25 Nm
- Reconnect brake lines to the master cylinder ports
- Reconnect electrical connector for fluid level sensor
- Reconnect battery
- Refill reservoir with fresh DOT 3/DOT 4 brake fluid
- Bleed the entire brake system starting from the wheel farthest from the master cylinder
- Check brake pedal feel — should be firm with minimal travel
- Perform road test in a safe area
- Re-check reservoir fluid level after test and top up as needed
