Detailed Description

NM55094 is a brake master cylinder for the Toyota RAV4 that restores hydraulic pressure from the brake pedal to the brake system. It is engineered as a standard replacement unit with a 0.875-inch bore, aluminum construction, and an integrated plastic reservoir to support dependable brake fluid delivery.

This part cross-references Toyota OE numbers 4720142040 and 4720142080 for the same application.

What It Helps Fix

• Low or inconsistent brake pedal feel
• Brake fluid leakage from the master cylinder body or reservoir area
• Internal hydraulic bypass that reduces braking pressure
• Pedal travel that increases as the hydraulic system wears
• Brake performance loss caused by a failing master cylinder on a Toyota RAV4

Installation Notes and Tips

Verify the vehicle is a 1996-2000 Toyota RAV4 with front disc brakes before installation. Bench bleed the master cylinder before connecting brake lines, then bleed the full brake system with DOT 3 fluid after installation. Mounting hardware, brake booster, push rod, sensor, and brake pressure switch are not included, so reuse or source those components as needed. Confirm the mounting hole pattern and line port alignment match the original unit before final assembly.

Quality Assurance

MPA Electrical tests each brake master cylinder against OE specifications using proprietary processes and strict inspection protocols to help ensure consistent braking performance out of the box.
