I have reduced strength in my legs and would like to know how the IS250 brake pedal effort compares to other symilar cars like BMW, Audi, MB. Honda, etc. Is it light? Have you ever noticed the BAS brake assist working when braking suddenly? Did it require much pedal force to "engage" its helping action? I am placing my order in two days and can´t try the brakes by myself. I have posted this question in the UK Lexus Club before.
