Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Rear Rotor Lateral RUNOUT
Check rotor lateral runout whenever diagnosis indicates pedal pulsation and rapid, uneven brake lining wear.
The rotor must be securely clamped to the hub to ensure an accurate runout measurement. Secure the rotor with the wheel nuts and 4 or 5 large diameter flat washers on each stud.
Use a dial indicator to check rotor lateral runout. Maximum allowable lateral runout is 0.003" (0.76 mm).
