Group A Brake Performance and Test Method
Choose and interpret the correct motorcycle brake performance method, including roller results, efficiencies, linked systems and decelerometer use.
How to prepare for this year's assessment
Start with group and vehicle class, confirm whether a rule applies, follow the prescribed inspection or administration method, and classify only the evidence permitted by the live source.
Core concepts
Concept 1
Choose and interpret the correct motorcycle brake performance method, including roller results, efficiencies, linked systems and decelerometer use.
Exam cue: Identify whether the scenario belongs to Group A or Group B before selecting a manual.
Concept 2
Identify the brake arrangement and test suitability before calculating or comparing performance with the applicable minimum.
Exam cue: Identify the brake arrangement and test suitability before calculating or comparing performance with the applicable minimum.
Concept 3
DVSA's current public example highlights linked hand- and foot-operated systems and when a decelerometer test is needed.
Exam cue: Use the source version and effective date that apply during the live 2026–27 training year.
Concept 4
The public example illustrates item form but is not reproduced or used as future question content.
Risk pitfalls and guardrails
Adding or comparing brake readings without first identifying how the linked system is operated and assessed.
Guardrail: Do not replace current manual wording with workshop preference, memory from an earlier year or an assumption based on appearance.
Treating workshop repair preference as the statutory MOT test outcome.
Guardrail: Do not replace current manual wording with workshop preference, memory from an earlier year or an assumption based on appearance.
Reproducing a sample answer without checking current application and evidence.
Guardrail: Use public examples to identify concepts only; the live source and current facts control the result.
Memory anchors
System Before Numbers
Identify which control operates which wheel or linked circuit.
Method Must Be Suitable
Use the roller or decelerometer route required by the manual.
Calculate Then Classify
Compare valid performance evidence with the current minimum.
Group A Brake Performance and Test Method: Source
Confirm the answer in the live DVSA guide, inspection manual or applicable special notice.
Group A Brake Performance and Test Method: Sequence
Identify group and class, confirm application, use the prescribed method, then classify the evidence.
Group A Brake Performance and Test Method: Annual Boundary
Keep the 2026–27 assessed topic allocation separate from live rule changes and earlier training years.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.

Check-up Questions
What minimum efficiencies apply to a Group A motorcycle with two service-brake controls?
On the roller brake tester, one wheel locks under a control before a higher reading can be obtained. What does that demonstrate?
