Understanding the Tapley Electronic Decelerometer
In the realm of automotive maintenance and safety, accurate brake testing is paramount. The new Tapley Electronic Decelerometer stands as a significant advancement in this field, offering a portable, accurate, and DVSA-approved solution for assessing vehicle braking performance. This device, re-engineered for MTS Connectability, is an essential tool for all classes of MOT testing in the UK, ensuring your vehicle meets the stringent safety standards.
What is a Decelerometer?
A decelerometer, in essence, is an instrument used to measure the rate at which a vehicle slows down. This is commonly referred to as deceleration. For vehicle safety, particularly during the MOT test, measuring a vehicle's braking efficiency is crucial. The Tapley Electronic Decelerometer, specifically the EBM model, houses an accelerometer that precisely measures this deceleration. It goes beyond a simple measurement, allowing for the evaluation of your vehicle’s braking performance by quantifying its forward deceleration, speed, and stopping distance. This provides a comprehensive understanding of how effectively your brakes are functioning.
Key Features and Benefits of the Tapley EBM
The Tapley EBM is designed with the professional mechanic and tester in mind, boasting a range of features that make it both efficient and user-friendly:
- Compact and Portable Design: Weighing very little and designed to be held in the palm of your hand, it’s incredibly convenient for on-the-go testing, especially on difficult-to-access vehicles like many 4x4s.
- DVSA Approval: Critically, it is approved by the DVSA (Driver and Vehicle Standards Agency) for all classes of MOT testing in the UK. This ensures that the results obtained are recognised and meet regulatory requirements. Its approval reference is Tapley EBM ref:EINCBD09863A1019110.
- MTS Connectable: The re-engineered model is MTS Connectable, meaning it can seamlessly integrate with the DVSA’s MTS (Motorcycle Testing System) Connected Network. Test results can be downloaded to a PC via a USB cable and sent directly to the DVSA, streamlining the reporting process.
- Clear LED Display: A bright 3-character LED display clearly indicates Service and Hand Brake efficiency, as well as overall brake test results. This makes it easy to read the data even in varying light conditions.
- Versatile Application: While excellent for cars and light commercial vehicles, it is also approved for Motorcycles, Trikes, and Quads (Class I, II, & III vehicles). For motorcycle testing, a specific DVSA-approved Motorcycle Handle Bar Bracket and Clamp is available as an optional purchase.
- Ease of Use: With simple one-button operation, the Tapley EBM is accurate and straightforward to use, minimising the learning curve and maximising efficiency.
- No Installation Required: This is a significant advantage. The device is a self-contained unit that requires no complex installation, meaning you can start testing almost immediately.
- PC Software Included: It comes supplied with Windows PC software that facilitates communication with the DVSA MTS system, aiding in data management and reporting.
- Warranty: A 12-month warranty is provided, offering peace of mind and assurance of the product's quality and reliability.
How the Tapley EBM Works
The Tapley EBM operates by utilising its internal accelerometer to measure the deceleration of a vehicle during a braking event. When placed in a vehicle and a brake test is initiated, the accelerometer records the rate at which the vehicle's speed decreases. This data is then processed to calculate:
- Service Brake Efficiency: This measures the effectiveness of the primary braking system.
- Hand Brake Efficiency: This assesses the performance of the parking brake.
- Stopping Distance: By analysing the deceleration, the device can also estimate the distance the vehicle takes to come to a complete stop from a given speed.
The device can also be used in conjunction with normal, routine inspections to monitor the condition of brake components over time. By tracking braking performance, potential issues with brake pads, discs, or hydraulic systems can be identified before they become critical safety concerns.

Comparison with Traditional Methods
Historically, brake testing might have involved more rudimentary methods or less precise equipment. The Tapley Electronic Decelerometer offers a significant upgrade:
| Feature | Tapley Electronic Decelerometer (EBM) | Traditional Methods (e.g., Roller Brake Testers) |
|---|---|---|
| Portability | High - handheld, no installation required | Low - fixed installation, requires drive-on |
| Accuracy | High - measures direct deceleration | High - measures force at wheels, but can be affected by tyre slip |
| Ease of Use | Very High - one-button operation | Moderate - requires vehicle positioning and understanding of the machine |
| Data Connectivity | Excellent - MTS Connected, PC download via USB | Varies - some offer printouts, digital output may require integration |
| Vehicle Suitability | All classes, including motorcycles (with bracket) | Primarily 4-wheel vehicles, specific setups for others |
| Cost of Setup | Lower initial purchase cost, no installation | Higher initial investment, installation costs |
