If this runout exceeds the threshold, usually around 0. Unlike low-speed shuddering, which points to warped rotors, this specific scenario suggests that the energy generated by the brake force is exciting a frequency in the steering column or hub assembly.
Understanding Rotor Face Damage from Uneven Brake Pad Wear
Brake Rotor Tolerances and Runout While general warpage often causes vibration at lower speeds, high-speed braking introduces extreme thermal stresses that can reveal subtle manufacturing defects. The hub must be measured for runout with a dial indicator, and the suspension components need to be checked for any play or damage that compromises the geometry during loading.
Severely under-inflated tires can develop excessive sidewall flex during hard braking, which can create a waving action that translates into steering vibration. 003 inches, the caliper piston will push against a surface that is not perfectly flat relative to the hub.
How Uneven Brake Pad Wear Leads to Rotor Face Damage and High-Speed Vibration
Even new rotors must meet strict specifications for lateral runout, which is the side-to-side movement of the rotor surface relative to the hub. Decoding the Specific Symptom To understand the root cause, you must first accurately describe the feeling.
