Product Overview
This air-over-hydraulic brake booster pump is exclusively developed for 5-ton wheel loaders, the core power-assisted component of vehicle air-liquid hybrid brake system. It adopts thickened integrated cast steel cylinder with anti-rust paint coating, matched with separate galvanized oil reservoir. Built-in pneumatic piston, hydraulic master cylinder and multi-layer oil & high-pressure resistant fluororubber sealing components. High-pressure air from air compressor enters air chamber to push hydraulic piston and squeeze brake fluid, amplify braking force and reduce pedal stepping burden. Air circuit and hydraulic circuit are physically separated to avoid cross leakage of air and brake fluid.
Mounting flange, air inlet and hydraulic outlet fully fit original chassis without bracket or pipeline modification during used loader refurbishment, realize plug-and-play replacement.Core Product Parameters

Core Product Features
- Cast Steel Booster Cylinder: Built-in air piston, high-pressure air pushes piston to amplify braking force
- Split Galvanized Oil Cup: Store brake fluid, transparent window for oil level observation with sealed dust cap
- High-pressure Hydraulic Outlet: Deliver pressurized brake fluid to front & rear brake wheel cylinders
- Compressed Air Inlet: Connect air output pipeline of foot brake valve for control air input
- Dust-proof Vent Port: Balance internal cylinder pressure, prevent dust and mud from damaging internal seals
Core Product Advantages
- Mounting flange hole distance, air inlet and hydraulic outlet positions fully match chassis of 5-ton used loaders. No pipeline cutting or bracket modification required during used loader refurbishment, single operator finish replacement within 10 minutes, greatly improve refurbishment efficiency.
- Multi-layer independent fluororubber seals separate air and oil circuits completely, eliminate high-risk mining faults such as air-oil mixing, empty brake pedal and sudden braking loss, greatly improve equipment operation safety.
- Integral thick cast steel booster cylinder resists vibration and impact without deformation or cracking. Matching split galvanized oil reservoir prevents rust and corrosion under long open rainy mining work, no leakage or rust, cut repeated spare parts purchasing cost.
- Air assist amplifies braking force for light pedal stepping under heavy-load climbing and continuous braking conditions, relieve driver fatigue caused by hard brake pedal of old booster s on used loaders, improve continuous construction efficiency.
