A pulsating brake pedal usually means uneven brake rotors. Here’s what causes it, which parts to inspect first, and whether you can keep driving safely.
Why Does the Brake Pedal Pulsate?
A pulsating brake pedal is almost always a sign that your front brake discs — the rotors — have developed uneven surfaces. Over time, heat and hard braking can create high and low spots on the rotor face, and your brake pads 'skip' across these imperfections as the wheel spins. This feels like a rhythmic pulsing or grinding through the pedal. On the Geely Geometry C, this is often caused by repeated hard stops, holding the brake after driving through water, or even over-tightened lug nuts at the last tire change.
