I am getting troubles with my toyota avensis verso: since 2002, when I got it, after 8000-10000 km I feel bad vibration from the front of the car breaking from 120 km/h to 60 km/h. These vibrations are so hard that all the car vibrates till I release the breaks. Everytime I go to the toyota service, they refinish the discs and, after further 8000 km they change discs (not always the pads). After 4 years I feel bored: toyota italia says is my driving style, but I drove several other car in this years and I didn't face the same problem.
What do you think about?
The reason your Toyota shakes under braking, is due to warped rotors. Sometimes it is the fault of the material in the rotors, but more often than not it is the way the wheels are mounted onto the brake rotors that cause the rotor to warp. The next time you take your brakes in for service, inquire about the method the technician uses to mount your front tires after brake service is completed. If they tighten the wheels up with an impact wrench and in a circle pattern; that is often the reason your brake rotors become warped and generate the shaking feeling. The wheel lugs should be tightened with a torque wrench, by hand, and using a star pattern to tighten them up. If they object to this procedure. Just have your service work done elsewhere, where they do.
If that isn't the case, then it IS your Driving Style! Stepping harder on the brakes for shorter, quicker stops, are better than the soft, foot dragging, excessive heat generating type of stopping that causes brakes to warp, and should be avoided.
Hope you experience better luck now that you know the facts!
