Detailed Description

This brake master cylinder is built for Toyota Sequoia applications from 2001 through 2007 and is intended for vehicles with front disc brakes. The aluminum body helps provide a durable OE-style hydraulic replacement, while the 0.9375-inch bore diameter supports proper brake system pressure for normal pedal response. If you are replacing a leaking, worn, or internally bypassing master cylinder on a Toyota Sequoia, NM55247 provides the core hydraulic components needed for service.

This part cross-references Toyota OE numbers 472010C030 and 472010C031 for the same application.

What It Helps Address

• Low or inconsistent brake pedal feel
• External brake fluid leakage at the master cylinder
• Internal seal wear that affects hydraulic pressure
• Brake warning symptoms caused by master cylinder failure
• Restoration of braking performance after hydraulic wear

Installation Notes and Tips

Before installation, confirm the vehicle is a 2001-2007 Toyota Sequoia with front disc brakes and verify the master cylinder bore and mounting configuration match the original unit. Bench bleed the master cylinder before connecting brake lines, then bleed the full brake system with fresh DOT 3 fluid to remove trapped air. Inspect the brake booster, lines, and fittings for wear or contamination during replacement.

Quality Assurance

MPA Electrical tests each brake master cylinder against OE specifications using controlled processes and sample-based validation to support consistent braking performance out of the box. Part Number NM55247 is a new, standard replacement brake hydraulic component for Toyota Sequoia service.
