Actually switching to Motul. The Castrol is great, but want something with a bit less comparability. So going to give RBF700 a try. Sent from my SM-G930F using FerrariChat.com mobile app
Do you mean “compressibility”? SRF has higher boiling points dry or wet, but doesn’t have as good “feel” like Motul. FWIW, I use Motul RBF 600 and haven’t had boiling issues, even on the track (albeit a technical track that’s not that hard on brakes). I could go to RBF 660 or SRF, but why?

Yep that's what I meant. Auto correct rears its ugly little head... I like as high a boiling poit as possible. My experience is, that the higher the boiling point, the more consistent the pedal feels through the operating range. I choose 700 because I get it for the same price as 660.

I too have a 488S and the braking power at high speed doesn’t feel right to me. I just took my Huracan out for a blast tonight and the difference in braking on the Huracan compared to the 488 is noticeable. Is it the brakes or the difference in weight that I’m feeling. I feel way more confident in my abilities behind the wheel of the Huracan than I do with the 488. That’s for sure.
There is a 488 Ferrari recall on breaks. Your breaks have a problem ! Sent from my iPhone using FerrariChat
Looks like I've been feeling the weight and you really need to work the 488 brakes to get the most out of them. It's just different from the Hurcan. Overall all is well. Sent from my iPhone using FerrariChat
I believe the recall is the same for the Pista. It’s just a replacement cap for the reservoir and a software tweak. I doubt that could be the issue in this case. Been using SRF in my other cars with great success.
Braking test Ferrari wins ) https://fastestlaps.com/comparisons/gvoe9o1efs35 Compare from magazine’s tests, Ferrari wins I had both 488 and Huracan, Ferrari brakes better IMO
Right. Braking should be at least comparable. If it’s weak, there’s a good chance some detailer used silicone-based tire dressing and got overspray on the rotors. Contaminated rotors will not stop well, and driving on them will just bake in the contaminants. The only way to clean it off is to use a solvent and even then, it’s not easy to remove it. Best not to use any tire dressings, or if you do, apply it to a sponge or rag and wipe it on. If the pedal is spongy, there’s probably air in the line. If the pedal is hard and a lot of foot pressure is needed, the booster or vacuum check valve might be compromised. But weak brakes on any Ferrari is not normal, and unless the prior owner or the dealer put in track or race pads, they shouldn’t need much warm up to bite well. OEM street pads have good cold bite.

Yes, agreed. I have taken my 488 spider through the car wash about 7 times this year. Today, after exiting the car wash the brakes felt like they had lost all pressure and the brake pedal completely sank in. Luckily I always drive in manual and was in 1st gear so I was able slow down a bit. I figured that the tire shine or solution the car wash uses on the tires got on the brake rotors or pads and caused the brakes to ultimately fail. Fixed the problem by going 100 a couple of times and pumping the brakes to rid what ever was on them causing the issue. never going through a car wash again. will stick to hand washes.
In your case it may be something other than, or in addition to tire dressing contamination. The brake pedal should not sink to the floor. You should get it checked. Sent from my iPad using FerrariChat
