- Brake shoes should be larger than a quarter on the steering axle.Coin diameter is not the handbook inspection criterion.
- Brake shoes should have the same thickness as a penny.A penny is not a brake-lining specification.
Test-Day Checklist
- Read the question once for the topic, then read it again for the exact CDL action being tested in General Knowledge.
- Eliminate answers that sound convenient but skip an inspection, warning sign, or safety step.
- Say the correct rule out loud before moving on so you can recognize it when the exam changes the wording.
