The STC500100 brake master cylinder assembly (late type) is designed for Land Rover Defender and Series IIA/III models, providing reliable hydraulic pressure for proper braking performance.

As a critical component of the braking system, the master cylinder converts pedal input into hydraulic pressure to operate the brakes. Over time, internal seals can wear out, leading to soft pedal feel, reduced braking efficiency, or fluid leaks. Replacing the master cylinder restores consistent braking response and system reliability.

This complete assembly includes the reservoir and cap, offering a convenient, ready-to-install solution for brake system service or restoration.

Ideal for brake system repairs, restoring pedal feel, and maintaining safe braking performance on classic Land Rover models.
