I totally agree with Kikemec and with 22, here in Mexico we call Boster, when the pedal gets hard it is for the servo since it uses the vessel that generates the engine to help the pedal this soft and be easier, comfortable and more powerful the braking, and also as our friends say they can be repaired, even if you inform how much it costs to see if you see if you see if you see if you see if you see if you see it.
