Road Test

NOTE: A road test will confirm or deny the existence of a problem. The final diagnosis procedure involves road test analysis and a visual inspection of brake components.

1. If the complaint involves a low brake pedal, make several low speed stops and note whether pedal returns to normal height. If pedal drops off, or brake action is impaired, immediately return to shop and begin repair.
2. Check brake pedal response with transmission in Neutral and engine running. Pedal should remain firm under steady foot pressure.
3. During road test, make normal and firm brake stops in 20-35 mph range. Note faulty brake operation such as pull, grab, drag, noise, low pedal, hard pedal, fade, pedal pulsation etc.
4. Inspect brake components and refer to Diagnosis by Symptom for causes of various brake conditions. Symptom Related Diagnostic Procedures
