The best method to test hoses is to have:
- The engine running for maximum boost.
- Have somebody pumping the brake pedal while somebody is inspecting the brake hoses.
- A torch to ensure plenty of light.
Brake hoses are inspected by visal inspection and feeling the hoses.

- Cracks in the outer ‘skin’ of the hose. Hoses may need to be bent for this test
- Blisters or Bubbles in the hose.
- Chafe marks from where it has been rubbing against something.
- Any wet marks where a hose is starting to leak.
- Any obvious bulging or expansion of the hose.
- Loose hose mounts or twisted hoses.

- Soft and weak hoses.

- Intermittent Brake Problem. This problem can be caused by a hose with an internal fracture creating a one-way check valve effect.
