Can I test brake efficiency on a walkaround?

No — that needs a roller brake test or equivalent. The daily check confirms the brakes function and that there are no leaks or warning lamps indicating a fault.

What if the ABS light stays on?

An ABS or EBS warning that doesn't clear is a defect and should be investigated before use — including where the warning relates to a coupled trailer.

How long should air pressure take to build?

It varies by vehicle, but slow build-up or pressure that won't hold points to a leak and should be reported as a defect.

How to check brakes on a daily walkaround

You can't test brake efficiency on a walkaround, but you can catch the warning signs — and a brake defect is never one to wave through.

In short

The daily brake check is about function and warnings, not a full brake test. It confirms the service and parking brakes operate, that air pressure builds and holds where fitted, and that no warning lamps or noises point to a fault before the vehicle moves.

What to check

Checking brakes, step by step

Service (foot) brake operates and feels normal
Parking / secondary brake holds the vehicle
Air pressure builds to normal and low-pressure warnings clear (where fitted)
No audible air leaks with the system charged
Brake warning lamps go out as they should
ABS/EBS warning lamp behaves correctly, including on any trailer

Common defects

Slow air build-up or leaks

Parking brake that won't hold

ABS/EBS warning lamp staying on

Binding or dragging brakes

When to fail it

Fail the item for any air leak that stops pressure holding, a parking brake that won't hold the vehicle, or an ABS/EBS warning that stays lit. Brake defects should take the vehicle off the road.

Why it matters

Braking defects are safety-critical and a priority at roadside checks. A vehicle that can't stop as intended endangers everyone around it, and brake faults feature heavily in serious-incident investigations.
