The average age of vehicles is increasing. And with age comes need. That’s why Haldex now offers a range of economical but safe, quality alternatives in spare parts based on vehicle age. All choices are available from the same source and are supported by the entire Haldex logistics and service organisation.

Grau – robust technology with a very favourable price/performance ratio

An established brand with a solid reputation is being relaunched.

Durable and reliable, Grau products are thoroughly tested for compliance with Haldex standards and come with a full warranty.

Our very latest addition to the Grau product range offered is a drum-brake 24/30 brake chamber, part number 3462430001.

KEY BENEFITS:

• Internal coil spring diameter is 0.5mm larger than spring used in other manufacturer’s designs, improving lifetime of spring by >30%

• The power spring adopts a limit device to extend the service life of the parking cavity.

• Surface treatment and anti-corrosion coating extend the service life of salt spray

• Double “O” ring sealed center section protects against air leakage and prolongs service life

• Special crimping method eliminates the risk of accidental release of the power spring and enables low profile clamp-free interference

• Steel inner rod and slotted center seal design improves the alignment of moving parts, prevents premature wear of seals and increases service life.
• The travel indicator provides a visual inspection function for proper brake adjustment

Because it’s from Haldex, every Grau brake chamber is tested to

the most rigorous standards. All testing done in accordance with

SAE J1469 to secure the required and expected performance levels

The testing carried out to ensure the product meets the required standards includes, but is not limited to, the following;

• Leakage requirement
• Force requirements on service
• Force requirements on parking
• Endurance testing
