HYDRAULIC BOOSTERS

Hydraulic boosters for vehicles without spare vacuum.

Where the engine cannot spare enough manifold vacuum — diesels, turbocharged petrol engines, many commercial chassis — assist comes from hydraulic pressure instead, usually shared with the power-steering circuit.

Why the distinction matters when sourcing

A hydraulic booster and a vacuum booster are not interchangeable and are not built on the same line. They have different failure modes, different test rigs and a different supplier base. Confirm which system your vehicle uses before comparing any reference numbers.

How they are specified

Input and output rod geometry, port thread and orientation, accumulator arrangement and mounting pattern. Cardone interchange numbers are the most commonly available cross-reference for this family in North America.

How to search this family

The same vehicle can be built with different brake-assist configurations depending on model year, engine and trim. Always confirm the configuration on the vehicle rather than assuming from the model name.
