Description
Reviews

Upgrade braking performance for heavy-duty builds. This Hydraulic Brake Booster Conversion Kit is designed for Toyota Land Cruiser 80 Series (HZJ80 / HDJ80) models using the 4-bolt brake booster mounting pattern.

The system replaces the factory vacuum brake booster with a hydraulic assist unit powered by the power steering circuit. This provides stronger and more consistent brake assist — particularly beneficial on vehicles running larger tyres, heavy bumpers, winches or expedition equipment.

System Type: Hydraulic (Hydro-Boost) | Mounting: 4 Bolt | Vehicle: Land Cruiser 80 Series

Why Upgrade to Hydraulic Assist?

Increased brake assist force
Improved stopping power with 35″+ tyres
Consistent braking performance under load
Less dependent on engine vacuum supply
Improved pedal response and modulation

How It Works

The hydraulic booster uses pressure from the vehicle’s power steering system instead of engine vacuum. This allows higher assist pressure and more reliable braking performance in modified and off-road applications.

Vehicle Compatibility

Toyota Land Cruiser 80 Series
HZJ80
HDJ80

1 × Hydraulic Brake Booster Assembly

Installation Notes

FAQs

1) What is the main benefit?
Stronger and more consistent brake assist, especially useful on modified vehicles.

2) Is this suitable for standard vehicles?
Yes, but the main advantage is realised on lifted or heavily equipped builds.

3) Does it improve pedal feel?
Yes. It typically provides firmer response with improved control.

4) Does it fit all 80 Series models?
It fits models with the 4-bolt mounting configuration. Fitment should be confirmed before ordering.

5) Is it suitable for diesel engines?
Yes. It is particularly beneficial on diesel-powered models.

6) Is this a bolt-on part?
It fits the 4-bolt mounting pattern but requires proper hydraulic integration.
