Key Features

– **Twin-diaphragm design** to increase the effective diaphragm surface area used for brake assistance.
– **Up to 30% increased braking capacity**, as claimed by Terrain Tamer.
– **Engineered for selected Toyota Land Cruiser applications**, including 76, 78 and 79 Series models.
– **Vehicle-specific options** for different model years and braking-system configurations.
– **Terrain Tamer engineering** for demanding 4×4 applications.

How Does a Twin Diaphragm Brake Booster Work?

A brake booster uses a pressure difference across its diaphragm or diaphragms to assist the force applied to the brake pedal. This reduces the amount of pedal effort required to operate the vehicle’s braking system.

The Terrain Tamer Twin Diaphragm Brake Booster uses two diaphragms to increase the effective area available for brake assistance. This is designed to provide greater assistance to the braking system than the corresponding standard single-diaphragm unit.

**Important:** A brake booster assists the braking system; it does not independently upgrade the vehicle’s brake discs, calipers or pads. Overall braking performance still depends on the complete brake system, tyres, vehicle condition, load and driving conditions.

Why Consider a Heavy Duty Brake Booster for Your Land Cruiser?

Touring and loaded vehicles

Touring equipment, canopies, drawers, accessories and towing can increase the demands placed on a vehicle’s braking system. A suitable brake booster upgrade may help provide additional brake assistance for a compatible vehicle.

Improved brake assistance

The twin-diaphragm design is intended to provide increased assistance when applying the brakes. The claimed improvement is specific to the booster and its intended application, and should not be interpreted as a guaranteed reduction in stopping distance.

Built for demanding 4×4 applications

Terrain Tamer offers different brake booster applications for selected Land Cruiser models and braking configurations. Choosing the correct unit is essential to ensure compatibility with the existing brake system.

Vehicle Compatibility and Part Numbers

Terrain Tamer lists Heavy Duty Brake Booster options for selected Toyota Land Cruiser 76, 78 and 79 Series models. The correct part number depends on the vehicle’s specification, production date and brake-system configuration.

Examples from Terrain Tamer’s application catalogue include:

These are indicative application references, not a complete fitment list. Confirm the exact part number against Terrain Tamer’s latest catalogue before ordering.

Before requesting a quotation, provide:
– Toyota Land Cruiser series and model
– Model year and engine
– Whether the vehicle has ABS
– Any relevant brake-system modifications

Do not select a brake booster based on the Land Cruiser series alone. Different model years and braking configurations may require different parts.

Terrain Tamer states that its Heavy Duty Brake Boosters are engineered and ADR approved for their intended applications. Australian Design Rules approval does not, by itself, confirm compliance with every South African vehicle modification requirement.

– Installation must be carried out by a qualified mechanic.
– The installed system must be inspected and signed off by an engineer where required by the applicable regulations.
– Confirm South African engineering certification and roadworthiness requirements before installation.
– Have the complete braking system checked after installation to ensure correct operation.

Brake-system components are safety-critical. Correct fitment, inspection and compliance are essential.

Frequently Asked Questions

What is a heavy duty brake booster?

A heavy duty brake booster is an upgraded brake-assistance component designed to help increase the force available to operate a vehicle’s braking system, reducing the effort required at the brake pedal.

What is the benefit of a twin-diaphragm brake booster?

A twin-diaphragm booster uses two diaphragms to increase the effective area available for brake assistance. Terrain Tamer claims up to a 30% increase in braking capacity for its specified applications.

Will it reduce my Land Cruiser’s stopping distance by 30%?

Not necessarily. The advertised figure refers to increased braking capacity, not a guaranteed 30% reduction in stopping distance. Actual stopping distance depends on the vehicle, tyres, road surface, speed, load and overall brake-system condition.

Is the Terrain Tamer brake booster suitable for all Land Cruiser models?

No. It is available for selected Land Cruiser applications. Model year, engine, ABS and other brake-system details must be checked to identify the correct part.

Do I need to upgrade my brake calipers and discs as well?

Not automatically. A brake booster upgrade and a big brake upgrade serve different purposes. A booster increases brake assistance, while a big brake kit changes components such as calipers, rotors and pads. Whether further upgrades are appropriate depends on the vehicle and its intended use.

Can I install the brake booster myself?

Fitment Centre is required. Terrain Tamer specifies installation by a qualified mechanic and engineering inspection and sign-off to meet applicable regulations. Confirm the relevant South African requirements before fitting.

Will the upgrade affect my vehicle warranty?

It may affect warranty coverage for the modified system or related components, depending on the manufacturer’s terms. Check with your vehicle manufacturer or warranty provider before proceeding.
