Since i've had my IS i've noticed a strange 'judder' when i break, i assume it's the ABS though i have to admit it seems odd for the ABS to be kicking in so soon. i drive at a leisurely pace but when i step on the breaks at say , medium strength, it judders and feels like the ABS engaging and dissengaging the breaks, no big thing i suppose, i just wanted to know if everyone elses IS200 is the same? cos this ABS feels different from my previous cars' ABS systems...
