What Causes a Vibrating or Pulsating Brake Pedal?
Have you ever felt your brake pedal vibrating or pulsing under your foot when braking? In some cases, this vibration may even extend to the steering wheel. This is a warning sign of a common braking issue known as “brake judder” — a symptom of potential brake system malfunction that could compromise your driving safety. What Causes Brake Rotors to Warp? 1. Heat-Induced Warping of Brake Discs Low-quality or non-standard brake discs may fail to withstand high temperatures generated during intense braking or long downhill driving. Excessive heat can distort the metal, causing the disc surface to become uneven. 2. Sudden Temperature Change When a hot brake disc is suddenly exposed to cold water — such as from driving through a puddle — the metal may warp due to rapid contraction and uneven thermal expansion, resulting in brake judder. This can sometimes be temporarily resolved by resurfacing (machining) the disc, but not always. How to Fix a Pulsating Brake Pedal 1. Brake Disc
