A pulsating brake pedal on your Kaiyi X7 usually points to uneven brake disc wear, pad deposits, or caliper issues. Here is what to check first and when to stop driving.
Why your Kaiyi X7 brake pedal pulses
When you press the brake pedal and feel a rhythmical pulsing, the most common culprit is uneven brake disc thickness or lateral runout, often described as warped discs. On a Kaiyi X7, this can happen after repeated hard stops, holding the pads against hot discs, cheap brake pads that leave uneven deposits, or corrosion and dirt between the disc and hub. A sticking caliper or seized slide pin can also keep a pad dragging, overheating one area of the disc. Less often, a worn wheel bearing, loose wheel, or an ABS issue can mimic the same feeling.
