High-quality cast aluminium body with corrosion-resistant coating – durable and lightweight
Updated diaphragm, check valve, and seals – prevents vacuum leaks and maintains consistent boost
Includes mounting studs, nuts, and gasket – ready for install
Compatible with factory or aftermarket master cylinders, vacuum hoses, and check valves
Meets or exceeds OEM specifications for boost pressure, pedal ratio, and durability

Benefits

Light, powerful brake pedal – eliminates hard pedal feel and long travel for better stopping power
Stronger vacuum assist – crucial for towing heavy trailers or stopping loaded rigs safely
Prevents brake fade under repeated use – essential for rural NSW highways, gravel, or off-road descents
Restores factory braking confidence – reduces driver fatigue on long drives
Essential for roadworthy compliance – weak or leaking boosters can fail inspection in NSW
Great for high-mileage work trucks, resto projects, or weekend Cruisers/Hilux – keeps stopping reliably

Frequently Asked Questions

What is the function of this dual-diaphragm vacuum brake booster? +

This vacuum brake booster utilizes an 8/9" dual-diaphragm layout to multiply the physical force you apply to the brake pedal. By leveraging engine vacuum pressure, it significantly reduces the pedal effort required to stop your vehicle, providing highly responsive, efficient, and reliable braking performance under demanding driving conditions.

Which Toyota LandCruiser and Hilux models is this booster compatible with? +

This right-hand drive (RHD) booster fits an extensive range of classic Toyotas. It suits LandCruiser 70 Series models built between 1984 and 2007 (such as the BJ70, FJ75, HJ75, HZJ75, HZJ79, and VDJ76), Prado 95 Series wagons (1996–2002), and fifth and sixth-generation Hilux models manufactured from 1989 through 2004—including petrol and diesel lines like the RN85, RN90, RN105, LN106, and LN167.

What are the symptoms of a leaking or failing vacuum brake booster? +

The most unmistakable sign is a hard, stiff, or woody brake pedal that requires massive foot pressure to stop the vehicle. You might also notice a distinct hissing sound coming from directly under the dashboard when depressing the brake pedal, an engine idle speed that drops or stumbles when the brakes are applied, or a vehicle that takes significantly longer to come to a complete stop.

How do I verify if this booster matches my vehicle's master cylinder? +

This replacement booster is specifically engineered to mount flush with factory OEM-specification 2-stud master cylinders. It is not compatible with vehicles running aftermarket or modified 4-stud brake master cylinders. Always visually inspect your engine bay to confirm your master cylinder utilizes a horizontal 2-bolt mounting pattern prior to installation.

What are the key safety steps required when replacing a brake booster? +

Proper execution during installation is absolute for system safety. Before unbolting hardware, disconnect the primary vacuum supply hose and check its inline check valve for correct operation. Carefully unbolt the master cylinder from the booster face without twisting or breaking the hard hydraulic steel fluid lines. Once the new booster is securely bolted to the firewall and connected to the pedal linkage, double-check that the pushrod depth is configured correctly before re-securing the system fasteners.
