Range Rover Classic Brake Hydraulics
Range Rovers are equipped with disc brake all round. Front discs are 298.17mm (11.75") diameter (solid discs up to October '89, vented from then onwards) and rears are 290.0mm (11.42") diameter. Rear discs on all models are solid.
ABS was fitted to Vogue SE models from '90 onwards as standard, and was available as an option on other models.
We have 3 kits available for uprating the Range Rover's braking system, depending on the year of the vehicle and whether just the front, or the front & rear, are to be improved. All of the kits contain grooved (handed) discs - ventilated at the front and solid at the rear - and carbon/kevlar pads.
To compliment our uprated brake kits, but also suitable for standard brakes, we stock stainless steel braided brake hoses, which improve brake line pressure and brake pedal feel.
Imperial & Metric threads - 1970 to 1989
The threads in the brake system of early (1970 to approx. 1984) Range Rovers are imperial (UNF). In 1984, calipers were changed to metric threads. Although similar in appearance, the two threads cannot be mixed; therefore, it is important to identify the type fitted to your vehicle before ordering replacement parts:
Imperial threads. Front axle suffices A,B,C,D & E and rear axle to suffix C, use imperial threads. (1970 to approx. 1984).
Metric threads. Front axle suffix F and rear axle suffix D (approx 1984) onwards use metric threads. In addition, metric threads are marked with the letter M on one of the flats on the base of the threads. Finally, with the introduction of metric threads, a new Lockheed master cylinder was fitted, incorporating an integral PDWA & warning switch.
Imperial & Metric threads - 1990 onwards
Witht he introduction of vented front discs from VIN GA (October 1989), imperial threads were again used in brake calipers. In 1994, these were changed to metric.
