Brake tester BT - perfect solution for inspection centres, truck services and transport companies

The Nussbaum brake tester program guides the operator automatically through the required testing procedure. After the automatic sels-test, the system checks the run out, rolling friction, braking force as well as the braking deviations. All values are clearly and precisely presented on the analogue displays and optional LCD-display. The design of the brake tester is functional, easy accessible and utilises a minimum amount of space. In fact, the roller sets fit into most existing pits for similar designs of brake testers.

The two 9 kw motors are situated underneath the rollers and the roller sets can be installed separated in combination with a pit or in a single foundation bed. The 50 mm elevated rollers promote very precise measurements while the worm gear transmission permits an easy exit from the roller sets. The sensor rollers are guided by two gas pressured springs, which facilitate deep profile tyre measurements. The plastic coated rollers enable maximum friction, even in wet conditions. The brake tester is fully galvanised for protection from corrosion, which guarantees a long efficient working life.

Upgradeable to diagnostic lines for trucks, cars and motorcycles

A new generation of brake testers The latest development of electronics for these brake testers enables a consistent concept to be used, integrating testing procedures for cars, trucks and motorcycles. The modular floor plan system for components (display unit, control unit, accessories...) offers a high flexibility to adapt the test line to various requirements and individual needs.

The subsequent upgrade possibilities guarantee an optimum return on investment. The new design of the analogue display for the brake tester generation BT shows an insight to the technical advancement available to everybody.

· Future orientated · upgradeable with PC · upgradeable to diagnostic line · PC supported analyzing programmes · step by step software · possibility of connection to specific networks like ASA-Network, MCTC-NET, GIEGNET, and others · industry approved CAN- Bus-Systems

1. Side Slip Tester: The easiest and fasted means of traction system diagnosis for vehicles up to 18 tons. Excellent reliability thanks to it's construction, which consists of two elements: the first platform neutralises the lateral forces and deformations effecting the tyres, which may not have been taken into account when measuring off-track running. The second platform is where the actual off-track running is measured by a transducer which registers lateral displacement in relation to the direction of drive in meters per kilometre. Results are shown on the 14-digit LCD display. 2. Suspension Tester for passenger cars: Uneven road conditions over a period of time can be simulated by the use of vibrating suspension plates. The actual road grip is permanently measured and the minimum road grip is measured according to the Eusama principle. Values are displayed as a percentage from which, information can be ascertained about the safety of the vehicle. (Please use cover plates when driving over with a truck)

3. Brake Test: When entering the roller set, the plastic coated rollers start turning. In addition to testing the applied brake system, it also tests rolling friction, run out, brake force and brake force differences as a percentage.

4. Visual Check and Headlight Test (HLT): After all measurable values are recorded; the visual check is the next stop. A checklist on the screen guides the user through the program enabling various checks to be marked as good or bad. An essential part of each visual check is the inspection of the suspension and steering. Hydraulic or pneumatic problems can be found very quickly and efficiently using the joint play detector. The low maintenance and sturdy equipment can be installed with a lift (optional) or integrated above a working pit. The HLT reliably tests filament, halogen and xenon headlight systems, with or without the optional luxmeter.





Together with your customer, you have now been able to complete a check of the most relevant safety related functions of the vehicle, hereby creating a solid foundation for an unbiased service offer. The entire testing procedure is a comprehensible process. The only quality assurance system for your service.
