Got a '17 488 GTB, picked it up in June (11k miles) and put 3,000 miles on it (not tracked). First exotic, so I could be worrying over nothing, but would appreciate your thoughts on possible brake issues. MAJOR SYMPTOM: - Braking hard from high speed, it has happened to me around twice that the brake pedal has gone 'hard' - a small amount of travel, then it will not depress any further despite applying maximum force - and stopping power is considerably diminished. This is NOT a regular occurrence, but then again I rarely brake hard from high speeds - maybe it would happen regularly if I did. Was a bit of a scare when I found myself hurtling toward a twisty off-ramp WAY faster than intended. MINOR SYMPTOM: - Brake squeal / hiss at low speeds. Function is fine. No big deal, I figured. Not unusual for CCs. Even some reviews mention it in passing without citing it as a defect. POSSIBLE CAUSES (from researching other threads): - Brakes were cold when applied at high speed. I was driving for 1hr+ on the highway, and moderating my speed mainly by lifting off the gas, not braking. Solution is simply to get some heat into them before smashing them from 100mp/h+. - Glazed brake pads / brakes not bedded in properly by the original owner. - Brake booster valve vacuum leak. OTHER INFO: - In normal city driving, the brakes work fine (despite the squeal). - In spirited driving on twisty roads, where I am accelerating hard and braking hard constantly, I have not experienced the 'wooden pedal' sensation - the brakes work as expected. - The car is due for service in January. I can ask them to flush the brake fluid / check the booster valve. MY QUESTIONS... 1. Even though the car now has 14,000 miles, would it be of any use to do a (belated) bedding in procedure? I would assume it's way too late if the discs are actually glazed, but no harm in a second opinion... Now, the big one... 2. The car is under full-cover warranty... For another 16 days. I can renew until the end of 2020. Service is not due until late January '21. I wasn't planning on paying the $6k to extend the warranty (not to open that can of worms here). Do you think, given the information set out above, that I should reconsider? Wouldn't want to cheap out on the $6k warranty in December and then be hit with a $20k brake replacement in January.
