When Should Brake Pads Be Replaced on Commercial Vehicles?

Why Brake Pads Wear on Commercial Vehicles

Commercial vehicle brake pads experience high friction, heat, and pressure, especially under heavy-duty conditions. Factors that accelerate wear include:

• Heavy vehicle loads

• Frequent stop-start driving

• Long-distance operation

• Demanding road conditions (including off-road use)

These conditions mean commercial brake pads wear faster than those on passenger cars.

How Often Should Brake Pads Be Checked?

Safety inspections should follow a time-based schedule, typically every 4–13 weeks depending on vehicle usage. Operators may also consider intermediate checks for high-wear components.

Operating Conditions	Recommended Inspection Frequency
Lightly loaded vehicles – easy operating conditions	10–13 weeks
General haulage – trunking	6–10 weeks
Arduous work – constant heavy loads	4–6 weeks
Off-road – difficult conditions	4 weeks
Vehicle/trailer 12 years or older	6 weeks

Important Update: From April 2025, laden roller brake tests or electronic brake performance monitoring systems (EBPMS) will, in most cases, be the only accepted methods for brake testing. A laden roller brake test is strongly advised at every safety inspection.

Signs Brake Pads May Need Replacing

1. Reduced Braking Performance

Indicators include longer stopping distances, more pedal effort, or declining roller brake test results. Always investigate reduced braking efficiency during routine maintenance.

2. Uneven Brake Pad Wear

Uneven wear may point to:

• Caliper problems

• Misalignment

• Other braking system faults

Early detection prevents further damage to the braking system.

3. Visible Pad Wear

During servicing, check friction material. Pads worn close to the backing plate should be replaced to maintain effective braking.
