Dorman - First Stop Brake Master Cylinder P/N:M630124
$94.99
Turn brake-pedal effort into the hydraulic pressure your brakes rely on with the Dorman - First Stop Brake Master Cylinder M630124. It installs as a direct-fit replacement for the 1998-2002 Toyota Sienna (All engines), feeding pressurized brake fluid to the wheel circuits through its two outlets.
- Aluminum construction: the cylinder housing is built to match the casting material of the original part for similar performance.
- EPDM seals: the rubber components use a high-quality EPDM compound for resistance to glycol-based brake fluid.
- 100% new: made entirely of new materials, not remanufactured.
- Built to spec: made to meet rigorous SAE International standards; 1 in bore, two outlets with M10 x 1.0 threads.
The master cylinder converts pedal force into hydraulic pressure across a split circuit. Signs this part may need replacing include a pedal that slowly sinks under steady pressure, a spongy pedal, or brake-fluid seepage at the cylinder; diagnose the cause before replacing. Mounting hardware, reservoir, and sensor are not included. Country of origin: Taiwan.
