Steering Wheel Shakes When Braking
The steering wheel vibrates or shakes during braking, which typically indicates a brake-related issue, most commonly warped brake rotors or uneven brake pad deposition on the front rotors.
Diagnosis Details
Possible Causes
Warped or unevenly worn front brake rotors (discs) causing pulsation felt through the steering wheel.
Brake pad material unevenly transferred to the rotor surface (pad glazing or deposition).
Loose or worn suspension components (e.g., tie rod ends, ball joints) that amplify brake-induced vibrations.

What You Should Do
Inspect front brake rotors for runout, thickness variation, and warping.
Measure rotor thickness with a micrometer and check lateral runout with a dial indicator.
If rotors are warped or below minimum thickness, replace them and install new brake pads.
Also check suspension components for looseness.
A brake lathe can resurface rotors if they have sufficient material, but replacement is often recommended for modern vehicles.
