Toyota lydenburg Hilux bakkie purchase

My bakkie started to shudder when I brake. I called toyota and the took my car and ther Skimmed the brakes.After repair the car still shudderd. After that I took the bakkie back to toyouta lydenburg agen and thet conducted testes. The did well balancing a d shaped the wheels around.And thet noted after ther tests that the bakkie was in good condition. The shuddering was stil thear after thet allegedly fixed the problem I took the bakkie personally for a a Dekra testing station. The attendance said that thear was shuddering in the bakkie. The report fount two flualts.That the front shok was worn and the sondar sensor in die back of the car wasn't working. I belive the the shuddering is ither coming from the breack system of from the Shock that is worn at the front. Greeting Henry
