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 STC1284 brake master cylinder?
This is the tandem brake master cylinder for the Discovery 1 (1989-1998) with servo-assisted ABS braking. It bolts to the vacuum servo and converts pedal effort into hydraulic pressure, feeding two independent circuits for the front and rear brakes.
Which Discovery 1 does this master cylinder fit?
This master cylinder fits the Discovery 1 servo-assisted braking system from VIN FA393361 to WA799999. Alternative part STC2903 also applies to this application. Check your VIN falls in range before ordering.
What are the signs the master cylinder is failing?
Signs on the Discovery 1 include a brake pedal that slowly sinks under steady pressure, or fluid loss with no visible leak, both pointing to internal seal bypass. A failing master cylinder should be replaced, not patched.
