What does the hydraulic brake booster use instead of engine vacuum?
What is a Hydro-Boost Power Assist Service? The hydro-boost power system works nearly identically to the vacuum-based system, but instead of relying on vacuum pressure, it uses direct hydraulic pressure. It is powered by the power steering pump and will typically fail at the same time as power steering.
Is there a vacuum brake on a Chevy Silverado?
When the vacuum produced inside of the engine is low, assisted braking is nearly zero. Fortunately, General Motors developed the Hydroboost system to combat this problem by assisting the brake master cylinder with fluid pressure from the power steering pump. This article applies to the Chevrolet Silverado GMT800 (1999-2006).
How does the Hydroboost system work on a Chevy Silverado?
The Hydroboost unit is plumbed into the power steering system, and uses the pumps pressure to aid in braking. Not only does this system allow constant brake assistance, but it increases the clamping force applied from the brake pads to the calipers.
What’s the difference between vacuum brake and Hydroboost?
The Hydroboost brake pedal has a shorter distance between the rod studs than the stock vacuum pedal. Install the larger brake pedal rod to the bracket using the 18mm bolt. Reattach the brake sensor and Hydroboost rod to the brake pedal with the small metal clip.

What kind of brake system does GM Silverado have?
The only thing that has not been replaced are the front brake lines. [h=2]Hydro-boost [/h] Though not as common as vacuum booster power brake systems, some vehicles are equipped with Bendix “Hydro-Boost” power brakes. This system uses hydraulic pressure generated by the power steering pump rather than engine vacuum to provide power assist.
