Land Rover Part Number: SJJ500070 - Brake Servo Booster Assembly
SJJ500070 is a Brake Servo Booster Assembly fitted to the braking system of Range Rover Sport L320 models with 2.7 TDV6 and 4.4 AJ-V8 engines. The booster provides vacuum-assisted amplification of pedal input to reduce the driver effort required when applying the brakes.
The unit contains the servo body and internal diaphragms which act on the master cylinder to convert driver input into hydraulic pressure at the brake calipers and wheel cylinders. The assembly supplied with this part includes the required seals for installation and replacement of a worn or damaged booster. Fitting this booster restores the correct mechanical advantage and can resolve symptoms such as a hard pedal feel or reduced braking responsiveness associated with a failed vacuum servo. Installation should follow manufacturer procedures for removal and refit of the master cylinder and vacuum hose connections, taking care to verify vacuum integrity and seal condition after assembly.
