Detailed Description
The MPA Electrical NM52017 brake master cylinder is built for Toyota 4Runner and Toyota Pickup models equipped with front disc brakes. It replaces the hydraulic control unit that converts pedal force into brake pressure, helping restore firm pedal feel and consistent braking response. The cast iron construction, 0.8125-inch bore, and included reservoir, cap, and seal support a straightforward master cylinder replacement for older Toyota brake systems.
This part number NM52017 cross-references Toyota OE numbers 4720135010 and 4720135160 for the same application. If you are searching for a Toyota 4Runner brake master cylinder or a Toyota Pickup master cylinder for front disc brake setups, this unit matches the listed fitment and hydraulic specifications.
What It Helps Solve
- Low or inconsistent brake pedal feel
- Internal master cylinder leakage
- Brake fluid loss at the hydraulic unit
- Reduced braking response from worn seals or bore wear
- Brake system restoration on older Toyota 4Runner and Pickup models
Installation Notes and Tips
Verify the vehicle’s front disc brake configuration before installation. Bench bleed the master cylinder before connecting brake lines, and use fresh DOT 3 brake fluid during service. Inspect the brake booster, lines, and wheel cylinders or calipers for wear or leaks so the repaired hydraulic system can operate correctly. Mounting hardware, brake booster, push rod, sensor, and brake pressure switch are not included.
Quality Assurance
MPA Electrical tests each unit against OE specifications using proprietary processes and strict inspection protocols drawn from its OE sample library. That validation helps ensure the NM52017 master cylinder is ready for service as a direct replacement brake hydraulic component.
