Brake Booster

WARNING: This page is about a different car, the 2020 Jaguar XE and 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

The brake booster gives a boost ratio of 6.3:1 to the effort applied to the brake pedal. The brake booster is attached to the driver side of the engine compartment bulkhead with a gasket, 2 studs and nuts.

The input actuator rod within the brake booster is connected to the brake pedal. The output rod locates in the primary piston of the brake master cylinder.
