While driving in hot temp days when I step in the brakes the brakes do not fully release causing the front end to shake abs the pads start to smoke. The front end vibrates. Eventually they release. This is something progressive as I drive and the car gets hotter. If I pull over the it stops but eventually it happens again. I have has pads and calipers replaced. 4 different mechanics have looked at it. No solution. Driving no but this summer I will replace the car if I can’t fix it. I really like the car and do not want to replace it
