Dorman - First Stop Brake Master Cylinder P/N:M630322
$122.99
Turn firm brake-pedal pressure into the hydraulic force that works your brakes with the Dorman - First Stop Brake Master Cylinder M630322. It installs as a direct-fit replacement for the 2004-2007 Toyota Highlander [All], taking over the original master cylinder's job of pressurizing brake fluid out to the wheel circuits.
- 100% new: built entirely from new materials, not remanufactured.
- Aluminum housing: the cylinder housing is constructed to match the casting material of the original part for similar performance.
- Fluid-resistant seals: rubber components use a high-quality EPDM compound to resist glycol-based brake fluid.
- Key specs: 0.875 in bore with two outlets on M10 x 1.0 threads (1 mm thread pitch); reservoir and sensor included. Mounting hardware is not included.
Made to meet SAE International standards. If a failing master cylinder is the cause of a slowly sinking or spongy pedal, or a dropping reservoir level with no visible external leak, this replaces it — diagnose the cause before replacing. Because mounting hardware isn't supplied, consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: China.
