There is a need for maintenance of every vehicle. An immediate attention is required to check the wear and tear. Regular repair is needed for the proper functioning of the vehicle. It is necessary to replace damaged parts to stay away from further damage to the vehicle.

If you want to keep your vehicle running smoothly, you need auto test products with the latest technologies and services. There are a number of manufacturers of auto test products that meet the highest standards in terms of quality, durability, reliability and safety. These are definitely the drivers of any successful auto industry, representing the basic features that come into any customer's mind. One popular auto test product being used is Roller Brake Tester (RBT), widely used in calculating braking efforts and efficiencies of vehicle. A Roller Brake Tester consists of chassis with a driven roller system. The other two brake testers are the hand held decelerometers, and the plate brake testers having two parallel measuring plates.

A Roller Brake Tester allows for dynamic assessment of the braking system of a motor vehicle, under stationary and controlled conditions. Using RBT, the brake force for each wheel, air pressure at the line as well as the wheel chamber, imbalance across all axles, test emergency brakes and parking brakes, in addition to comparing Brake force with air or hydraulic pressure, pedal pressure and display brake force are shown in due course. RBT also allows in finding Ovality and Cracking in drums as well as Warping of disc brakes. This kind of testing is done on a mechanical floor unit containing electrical motors, brake force transducers, two independent sets of three measuring rollers along with additional safety sensors.

Correct Brake Testing helps the technician in determining the performance of the brakes, in addition to effectively and efficiently locating possible faults in the braking system that often goes undetected. It is imperative to reduce rolling resistance of wheels. Approximately 40% of total fuel consumption is ascribed to overcoming the rolling resistance and is due to potential component wear. It should be noted that the ideal rolling resistance should be 3-4% of the individual wheel weight.

Some of the usual problems associated with rolling resistance include brake pad dragging on drum, foreign matter rubbing on wheel, leak in pressure valve, under inflated tyres and tight bearing. Organisations that mostly use Roller Brake Testers include heavy vehicle manufacturers in production lines and research, heavy vehicle repair workshops, heavy vehicle inspection stations, bus and coach companies, mining companies, airline companies and road police. Roller Brake Testing helps to show and measure the values including crack pressure, brake force on each wheel, time lag, service line pressure Pm, rolling resistance Px, Disc run-out, cylinder pressure Px, imbalance in %, axle weight and efficiency.

MAHA MBT 5251 Portable Roller Brake Tester

The MAHA MBT 5251 portable roller brake tester meets the current challenge of taking safety to any location. These were designed especially for the mobile application of brake and suspension tests on cars, vans and commercial vehicles, anywhere and anytime.

Maha have achieved this by utilising the main internal parts of the already world proven MBT 5250 above ground brake tester and fitting the rollers and a single action suspension test plate system into an all new purpose built trailer. The entire system can be towed to virtually any location. Set up is a simple one man operation, as the main test bed is lifted on and off the trailer via its own internal hydraulic driven rams.

Low drive-over height of only 150 mm allows for almost any vehicle with up to an axle load of 18tonne to be tested, even those with low ground clearance. Another advantage of the low drive-over height is that only short and light-weight ramps are required. The 3 tonne trailer is also equipped with shaker plates for forward and lateral movement operated by a cordless controller with built-in LED light. The unit is operated off its built in generator which drives the computer and the two 11kw motors.

The MBT 5251 series utilises digital data storage for recording and storage of measurement values. The display of data with the EUROSYSTEM software is via the radio touch screen and includes large easy-to-read dials displaying colour coded measurement values. Axle weight, deceleration and percentages of force are all measured or calculated and clearly displayed or printed. The Maha MBT 5251 is perfect for truck and bus companies with several depots, the unit can quickly be packed up and transported from one depot to another allowing compliance testing of the entire fleet with a single unit. The quality and accuracy is guaranteed, as are all German made Maha units, numbering over 60,000 brake tester units worldwide since the company’s inception in 1969.
