What is Brake Tester

A brake tester is a device used to measure the efficiency and effectiveness of automotive braking systems. It ensures that the brakes on a vehicle are performing within acceptable safety parameters as set by regulatory bodies. Brake testers are essential tools for vehicle inspection stations, garages, and workshops to ensure compliance with roadworthiness standards. They help identify issues such as worn brake pads, disc rotor problems, air in the brake lines, or malfunctioning brake components. Regular brake testing is crucial for maintaining vehicle safety and preventing accidents caused by brake failure.

Features of Brake Tester

Testing Can Be Done in 10-15 Minutes

Brake Tester reduces service time by automating brake system inspection so testing takes less than 15 minutes. Quicker testing allows your technicians to perform other work, thereby increasing productivity.

Improved Safety

Brake Tester can help prevent accidents by ensuring that the vehicles you are working on have properly functioning brakes.

Reduced Liability

By identifying and repairing brake problems before they cause an accident, a garage can reduce its liability risk.

Increased Efficiency

Brake Tester can help garages complete brake inspections more quickly and easily, compared to, for example, Decelerometers. This can free up technicians to work on other vehicles, which can improve efficiency and profitability.

Types of Brake Tester

Roller Brake Tester

Roller brake testers use a floor-mounted set of rollers to measure brake force. Two wheels of the vehicle are mounted on to each of the rollers, which are covered with a plastic material that provides friction. A third roller, located by each of the primary rollers, detects the presence of the vehicle and whether there is tire slippage. The wheels are turned at a constant speed over the rollers as the vehicle sets motionless. Measurement is calculated by the torque force produced by the deceleration of the wheels against the rollers, which operate at low speed to avoid stress on the wheels or vehicle.

Plate Tester

The plate tester is somewhat similar to the roller brake test. As with the roller version, two parallel plates are installed in the ground and mounted on a force transducer that measures force, weight, and pressure. The data collected by the transducer is sent to a computer. Force inducers are perfectly suited for computers since they produce either analog or digital data and come in several sizes. As the wheels cross the skid plates, the brakes are applied to cause the plates to slip producing a calculation of braking force.

Decelerometer

The decelerometer test is a road test where a devise is strapped to the passenger seat of the vehicle. The equipment measures inertial force as the vehicle decelerates. The speed of the vehicle is predetermined prior to beginning the test and must be constant for it to be accurate. Regardless of brand of decelerometer being used, the g-force principle or gravitational force equivalent, the reaction of one force against another, is used to measure the efficiency of the brakes.

Parts of Brake Tester

Structural Steel
The frame and base of a brake tester are typically made from high-strength structural steel, which provides stability and durability. The steel must be able to withstand the forces exerted by heavy vehicles during braking tests.

Rollers or Drums
Roller brake testers use a set of rollers that the vehicle's wheels drive over. These rollers are often made from cast iron or steel, which can handle the high torque and friction generated during braking tests.

Load Cells
Load cells or force transducers are used in both roller and in-ground brake testers to measure the force exerted by the vehicle's brakes on the rollers or drums. These are precision instruments made from metal alloys and contain strain gauges that convert mechanical force into an electrical signal for measurement.

Electronics
Modern brake testers are equipped with electronic control units (ECUs), microprocessors, and software that analyze the data collected from the load cells and other sensors. These components are made from silicon and various metals and plastics.

Control Panel and Display
The operator interface typically includes a control panel with buttons, switches, and a display screen. The control panel may be made from plastic or metal, and the display screen is usually an LCD or LED panel.

Sensors
Additional sensors may be used in brake testers to measure variables such as wheel speed, temperature, and deceleration rate. These sensors are made from a variety of materials including metal, ceramic, and plastic.

Pneumatic or Hydraulic Systems
Some brake testers use pneumatic or hydraulic systems to apply a consistent force to the rollers or drums during testing. The components of these systems, such as cylinders, hoses, and valves, are made from metal, rubber, and synthetic plastics.

Fasteners and Hardware
The assembly of a brake tester requires various fasteners and hardware components such as bolts, screws, nuts, and washers. These are typically made from steel, stainless steel, or brass to ensure durability and resistance to corrosion.

How to Choose Brake Tester

Operation

Brake Tester will measure the torque reaction generated by the vehicle brakes against a roller turned by a motor, while the plate brake testers have strain gauges attached to a plate supported on bearings, and measure the forces required to hold the plate, when a vehicle is braked on top of it. Decelerometers are placed in the vehicle and have a pendulum (more recently, airbag type accelerators) that moves when a vehicle is braked. The amount of ‘swing’ on the pendulum is measured to indicate deceleration during braking.

Safety

Brake Tester is a comparatively safe method of testing, as the vehicle does not move during the brake test. Instead the rollers act as the road and turn under the wheels. With both the plate brake tester and the decelerometer, testing requires the vehicle to be driven and braked on the plates, usually within the confined space of a vehicle workshop or roadside. This could be a hazard to other road or workshop users.

Accuracy

Brake Tester use the same braking surfaces to test all of the wheels, on all of the vehicles; ensuring accurate comparative tests. Plate brake testers use the same braking surfaces for all of the wheels, on all of the vehicles, while the decelerometer tests on-road so the braking surface can vary from very good to very bad, depending on conditions. While roller brake testers test all vehicles at a consistent test speed, both the Decelerometer and Plate Brake Testers tend to test at variable test speeds; depending on how the vehicle is driven.

Adaptability

Brake Tester can test the entire range of every brake fitted to the vehicle, from zero to full braking, or wheel lock, consistently and repeatedly, without the influence of momentum or weight transfer. The plate brake testers and decelerometers cannot test the entire range of a vehicles brake successfully. Decelerometers cannot test individual axles, plate brake testers can compare the balance of brakes across individual axles, while roller brake testers are able to consistently and repeatedly compare the balance of the brakes across individual axles.

How to Use Brake Tester

Prepare

Make sure the vehicle is parked on a level surface in a safe and suitable location for the brake test. Verify that the vehicle's parking brake is released and the transmission is in Neutral (for manual transmission vehicles) or Park (for automatic transmission vehicles).

Position

Properly position the vehicle on the brake tester equipment. Align the vehicle with the brake tester according to the manufacturer's instructions, making sure the wheel is centered on the roller or sensor.

Initialization

Turn on power to the brake tester device and allow it to complete the initialization process. Some brake testers may require calibration or setup procedures before testing can begin.

Implement

Follow the on-screen prompts or instructions provided with the brake tester device to initiate a brake test. This may involve activating the vehicle's brakes using the brake pedal or the parking brake lever, depending on the test mode selected.

Monitor

Monitor the brake tester device's display or readings during the test to observe brake performance indicators such as braking force, brake balance, braking distance, and any warning indicators or error messages.

How to Maintain Brake Tester

Daily Checks

Inspect the tester before each use for any signs of damage or wear. Check that all components are securely attached and that there are no fluid leaks.

Cleaning

Keep the tester clean. After each use, wipe down the rollers or drums to remove brake dust and debris. Clean the control panel and display screen as needed.

Calibration

Periodically calibrate the brake tester according to the manufacturer's recommendations. This ensures that the measurements remain accurate.

Lubrication

Apply lubricant to moving parts, such as the rollers or drums, and any other components that require it to reduce wear and prevent binding.
