2017 488 with no braking power! Advice this is my first Ferrari! I just purchased a 488 spyder, 12k miles. I had the car serviced at the dealer and asked them to check it out. Also Had them do a brake flush and bleed! The pedal is firm not mushy. Around town driving the car stops ok. At 100+ this car doesn’t stop for crap. Two feet in, no different, almost blasted into a car at the end of an exit ramp because I could stop the car. Terrible terrible, not safe, unlike my Porsche turbo, it’s got bite, no matter how many months the car sits... I have a fair amount experience ~ 35k Mike’s of track time with Porsche. So I think I understand braking ...there something wrong with this machine. Could it be a vacuum leak, brake servo problem or vac filter ? Ideas pls. cant drive the car like this!!
