Brake Master Cylinder - ABS is the tandem master cylinder at the head of the hydraulic braking circuit, specified for the servo-assisted anti-lock braking installation.

It bolts to the face of the vacuum servo and converts servo-assisted pedal effort into hydraulic pressure, feeding two independent circuits so that a leak in one still leaves braking on the other. The fluid reservoir mounts directly on top of the cylinder body.

The anti-lock specification is not interchangeable with the non-ABS cylinder. Replacement is indicated by a pedal that sinks slowly under steady foot pressure with no external leak, or by fluid loss at the rear of the cylinder where it meets the servo.

Bleed the complete system after fitting, and bench-bleed the cylinder first where access allows.

Frequently asked questions

What is the Brake Master Cylinder (STC1284) and what does it do?
The STC1284 is the brake master cylinder for the Discovery 1 (1989-1998) servo-assisted braking system. It converts brake pedal force into hydraulic pressure to operate the brakes at all four wheels.
Which vehicles does this brake master cylinder fit?
This brake master cylinder fits the Discovery 1 from VIN FA393361 to WA799999 with the servo-assisted braking system. Check your VIN to confirm before ordering.
Is STC2903 an alternative to this master cylinder?
STC2903 is a listed alternative code for STC1284, referring to the same Discovery 1 brake master cylinder. You can order under either reference.
What are the signs the brake master cylinder needs replacing?
A failing brake master cylinder usually causes a sinking or spongy brake pedal, loss of brake fluid, and reduced braking. As a safety-critical part, replace it promptly and bleed the system fully after fitting.
