Symptoms of Brake Vibration and Pulsation

1) SYMPTOMS OF BRAKE VIBRATION AND PULSATION

Brake vibration problems generally involve one or both of two phenomena: body vibration and/or pedal pulsation.

A. BRAKE VIBRATION:

Figure 1:

Applying brakes causes vibration to occur in the instrument panel, steering column, steering wheel, and/or body of the vehicle (see Figure 1).

B. PEDAL PULSATION

Figure 2:

Applying brakes causes the brake pedal to pulsate. This brake pulsation sometimes causes the steering wheel to oscillate when the brakes are applied (see Figure 2).
