Service function guideBrake Vibration Diagnosis

This guide equips motorists and working mechanics with a structured diagnostic procedure to isolate the root cause of brake vibration, commonly felt as judder through the steering wheel, pedal, or seat. It begins with a clear explanation of how the braking system generates and transmits vibration, then moves through preparation, a full step-by-step inspection and measurement routine, and verification testing. Readers will learn to distinguish between rotor thickness variation, wheel-end play, caliper drag, and suspension compliance faults using basic hand tools and a micrometer. By the end, they will be able to perform a repeatable diagnosis, document findings, and decide whether resurfacing, replacement, or further chassis repair is required.
