Land Rover Part Number: STC1284 - Brake Master Cylinder - ABS
STC1284 is a Brake Master Cylinder - ABS. Fitted to Discovery 1 models with ABS and a servo-assisted braking system, this assembly supplies hydraulic pressure to the anti-lock braking system and the primary brake circuits when the brake pedal is applied. The unit contains separate chambers to feed the ABS modulator and the conventional brake lines, maintaining brake pedal feel and proportioning pressure between circuits. Replacement is required where the piston seals, reservoir, or internal bores are worn, contaminated, or damaged, or where hydraulic leaks or internal bypassing affect pedal pressure.

Its dual-chamber design feeds both the ABS modulator and the conventional brake lines while preserving pedal feel and pressure proportioning. Common failure modes include worn or contaminated piston seals, damaged internal bores, or reservoir leaks which can lead to reduced pedal pressure or internal bypassing.
