A pulsing brake pedal on a Jetour X70 almost always points to disc thickness variation — warped rotors or uneven pad deposits — rather than a sensor fault. Here’s what to check and whether you can keep driving.
If your Jetour X70's brake pedal kicks back or shudders as you slow down, you're feeling something real — and it's usually not your imagination or the road surface. The most common culprit is the front brake discs, specifically something called disc thickness variation (DTV). What people call "warped discs" is often not a bent piece of metal at all, but an uneven transfer layer of pad material baked onto the rotor face. Once one spot is thicker than the rest, the caliper gets pushed and released with every wheel rotation, and that rhythmic push travels straight up through the hydraulic lines into your foot. If the steering wheel also shakes, the fronts are the prime suspect; if only the pedal pulses and the wheel stays calm, look at the rear discs.
