Vehicle maintenance is required at some point in time. Checking for wear and tear typically necessitates immediate attention. Sometimes a routine repair is required for the automobile to work properly. It is critical to repair worn-out and damaged parts in order to prevent additional harm to the vehicle.
If you want your car to perform smoothly, you must use Car service Harlow items that use cutting-edge technology and services. There are several producers of car test products that satisfy the highest quality, durability, dependability, and safety criteria. These are definitely the drivers of any successful auto industry, representing the basic features that come to any customer's mind.
One very popular auto test product being used is the Roller Brake Tester, widely used in calculating the braking efforts and efficiencies of vehicles. A Roller brake tester consists of a chassis with a driven roller system. The other two brake testers are the hand-held decelerometers and the plate brake testers, which have two parallel measuring plates.
A Roller Brake Tester (RBT) 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, will be shown in due course. RBT also allows for 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, and additional safety sensors.
Correct Brake Testing helps the technician determine the performance of the brakes, in addition to effectively and efficiently locating possible faults in the braking system that often go undetected.
It is imperative to reduce the rolling resistance of wheels. Approximately 40% of total fuel consumption is attributed to overcoming 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 or disk
Foreign matter rubbing on wheel
Leak in pressure valve
Under-inflated tires
Tight bearing
Organizations that mostly use Roller Brake Testers include:
Heavy Vehicle manufacturing in production lines
Heavy Vehicle Manufacturing in research
Heavy Vehicle Repair Workshops
Heavy Vehicle Inspection Stations
Bus and Coach Companies
Mining Companies
Airline Companies
Road Police and Armed forces
Roller Brake Testing helps to show and measure the following values:
Crack pressure and Threshold
Brake force on each wheel
Time Lag or reaction time
Service line pressure (Pm)
Rolling resistance (Px)
Ovality / Disc run-out
Cylinder pressure (Px)
Imbalance in %
Axle Weight
Efficiency
Graphical presentation of test results
The benefit of undertaking Roller Brake Testing lies in the simultaneous presentation of all key values.
