Overview
Hydraboost systems represent advanced hydraulic brake booster technologies designed to enhance braking power in heavy equipment and medium-duty vehicles. Unlike traditional vacuum boosters, hydraboost units employ hydraulic pressure, often sourced from the power steering pump, to assist brake application. Incorporating an electric backup enhances safety by maintaining brake operation in case of engine failure or hydraulic pump issues.
System Architecture
The Hydraboost electronic backup system offers a significant safety enhancement for heavy equipment brake systems by ensuring consistent brake assist regardless of engine or hydraulic failures. By combining hydraulic power with electric motor backups, these systems promote reliability and maintain braking performance critical for operator and jobsite safety. Their adaptation across various commercial and construction vehicles underscores their importance in modern heavy machinery brake technology.

System Architecture
- The primary booster harnesses high-pressure fluid from the power steering system, amplifying driver input force on brake pedals.
- A compact electric motor-driven hydraulic pump acts as a backup power source.
- In normal operation, hydraulic pressure derives from the engine-driven pump; the electronic backup engages only during power loss scenarios or engine-off conditions.
- Backup motors typically operate on 12V or 24V electrical systems with dedicated wiring harnesses for control and monitoring.
- Continuous braking capability ensures enhanced safety even if engine stalls or power steering belt fails.
- Eliminates dependence on vacuum sources, suitable for diesel engines or turbocharged powertrains where vacuum is limited.
- Electric backup's immediate response improves emergency stopping performance.
- Reduces maintenance downtime by providing redundant braking power.
- Commonly installed in medium-duty trucks, school buses, motorhomes, and heavy construction machinery.
- Retrofitted systems can replace older vacuum assist or non-boosted brake setups.
- Compatible with various brake system configurations with adapters and wiring tailored for specific vehicle makes and models.
- Backup motors often come with replacement seals and connectors for maintenance and repair.
- Systems may include flow switches and relays to coordinate booster and backup motor operation.
- The hydraulic booster unit typically works at pressures around 1,500 psi, adapting to vehicle braking demands.
- Hydraboost: Hydraulic-assisted brake booster powered by the vehicle’s hydraulic system.
- Backup Motor: Electric motor providing auxiliary hydraulic pressure if main source fails.
- Power Steering Pump: Pump providing hydraulic pressure to steering and brake booster.
- Vacuum Booster: Traditional brake booster using engine vacuum to increase pedal force.
- Flow Switch: Sensor monitoring hydraulic fluid flow in brake booster circuits.
