GMC Hydraulic Power Brake Booster
31 items
A hydraulic power brake booster uses hydraulic pressure to help reduce the pedal effort needed for braking. On some vehicles the power steering pump supplies that pressure, while the brake master cylinder operates a separate brake-fluid circuit.

A hydraulic power brake booster uses hydraulic pressure to help reduce the pedal effort needed for braking. On some vehicles the power steering pump supplies that pressure, while the brake master cylinder operates a separate brake-fluid circuit.
A-Premium offers hydraulic boosters for selected applications. Match the booster to the original system, including the pedal connection, mounting and hydraulic line ports.
Choosing A Hydroboost Brake Booster
Hydraulic and vacuum boosters use different assist arrangements. Select the design specified for the vehicle rather than choosing by the bolt pattern alone.
Check the connection to the master cylinder and the listed package contents. A change in pedal effort or a leak can involve the booster, hydraulic supply or another brake-system component and calls for diagnosis.
Frequently Asked Questions (FAQ)
How does Hydroboost differ from a vacuum brake booster?
A hydraulic booster uses pressurized fluid for assist; a vacuum booster uses a pressure difference across a diaphragm. The vehicle's original system determines the correct replacement and connections.
Is the brake master cylinder included with the booster?
The listed A-Premium Tahoe/Yukon and Ford F-450/F-550 boosters specify that the master cylinder is not included. Check the contents of the selected booster for the parts required by the repair.
Does a hydraulic booster use the same fluid as the brakes?
In a typical power-steering-fed system, the booster assist circuit uses power steering fluid and the master cylinder supplies the separate brake-fluid circuit. Use only the fluids specified for each vehicle circuit.
Can low steering-system pressure affect brake assist?
On a booster supplied by the power steering pump, a supply problem can increase brake pedal effort as well as affect steering assist. The booster, pump, fluid and lines should be diagnosed as a system.
Can I replace a vacuum booster with a hydraulic unit directly?
The hydraulic unit needs the correct pressure supply, line routing and pedal and master-cylinder connections. It is not a direct replacement for a vacuum system without a vehicle-specific conversion design.
