Brake System FAQ

Question 1

What is a Hydro-Boost brake system and why use it?

Accepted Answer

A Hydro-Boost system uses power steering pressure instead of engine vacuum to provide brake assist, making it ideal for diesel engines, high-performance engines with large camshafts, and vehicles requiring increased braking force.

Question 2

What is the difference between Hydro-Boost, Hydro-Max, and air-hydraulic systems?

Accepted Answer

Hydro-Boost uses power steering pressure, Hydro-Max uses an electric pump for hydraulic assist, and air-hydraulic systems use compressed air to generate hydraulic braking force. Each system is suited to different vehicle types and operating conditions.

Question 3

What is an electric brake booster such as iBooster?

Accepted Answer

Electric brake boosters use an electric motor and control system instead of vacuum or hydraulic pressure to provide brake assist. These systems are common in modern vehicles and EV platforms.

Question 4

Why upgrade to a modern brake system?

Accepted Answer

Modern brake systems provide improved stopping power, better reliability, and compatibility with modified or heavy-duty applications where original systems are no longer sufficient or serviceable.
