I have a problem with my Nissan X-Trail T31 (October 2007). If I go slowly and push the brake it feels like brakes in waves, and if I drive at speed and then brake tracing the sensation of braking waves are transformed into powerful vibrations.
I changed the brake discs and pads on the front, front arms also have changed, I have changed all joints - I have nothing to spare - but the problem remains the same.
