Convert firm brake-pedal pressure into the hydraulic force that operates the brakes with the Dorman First Stop Brake Master Cylinder (M630562). It installs as a direct-fit replacement for the 2015-2016 Lexus NX200T, 2018-2020 Lexus NX300, 2015-2016 Lexus NX300H, and 2006-2019 Toyota RAV4 (All engines). Dorman precision-engineers this unit to the design, function, and performance of the original master cylinder for the listed applications, using all-new materials.
Signs the original master cylinder may need replacing include a pedal that slowly sinks to the floor, a soft or low pedal, or brake-fluid seepage. If a failed master cylinder is the cause, this replaces it. Mounting hardware is not included — consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: Taiwan.

This part cross-references / interchanges with the following part numbers:
What does this master cylinder do?
It converts the force applied at your brake pedal into hydraulic pressure that operates the vehicle's brake system through two outlets.
Which vehicles does M630562 fit?
It's a direct-fit replacement for the 2015-2016 Lexus NX200T, 2018-2020 Lexus NX300, 2015-2016 Lexus NX300H, and 2006-2019 Toyota RAV4 (All engines).
Does it include a reservoir and sensor?
Yes — the reservoir and fluid-level sensor are included. Mounting hardware is not included.
What is it made of?
The housing is aluminum, constructed to match the casting material of the original part, and all rubber components use a high-quality EPDM compound that resists glycol-based brake fluid.
What are signs the master cylinder may need replacing?
A pedal that slowly sinks to the floor, a soft or low pedal, or brake-fluid seepage. Diagnose the cause first, since these signs can have other sources.
