Re: Stiff brake pedal when starting
It´s not that easy any more, if you have front assist the brake has additional sources for activation, interfering with the brake booster.
You can empty the booster by rapid pumping of the pedal (pedal stiffens up)
Basically, as long as you feel the pedal getting "softer" once the engine is running, everything should be alright. Don´t worry if its more rigid in the morning,no problem.
