Brake Test

WARNING: This page is about a different car, the 2019 Ford F-550 Super Duty, 2019 Ford F-450 Super Duty, 2019 Ford F-350 Super Duty, and 2019 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

To carry out this test, proceed as follows:

Warm the brakes by slowing the vehicle a few times from 80-32 km/h (50-20 mph) using light braking applications. At highway speeds of 89-97 km/h (50-60 mph), apply the brake using a light pedal force.
Accelerate to 89-97 km/h (55-60 mph).
Lightly apply the brakes and slow the vehicle to 30 km/h (20 mph).
A brake vibration noise can be felt in the steering wheel, seat or brake pedal. A brake noise can be heard upon brake application and diminish when the brake is released.
If the source of the symptom has been identified as a result of this test, proceed to the appropriate brake information for further diagnosis and repair. If the source has not been identified, continue with the road test.
