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
Hello, I need your advice on 488Gtb. Car has under 1,500miles. Brakes are bad, soon gonna replace vacuum booster assembly. My pads are making loud noise when i release them, seems like they touch rotor in specific place. I want to change pads, and saw you were saying about Pagid. Shall I go for RSL yellow for street use? Pair them with Motul 600 dot4? Appreciate your help , thank you
1500 miles and brakes are worn out? That's not adding up. If you use Pagid use RSC1 not RSL29 yellows. Motel RBF700 infield is awesome fluid too. RSB600 is fine as well just the 700 is there latest greatest fluid. Be sure to notch out the pads so they match the oem pads and not touch the small inner part about 12mm wide in the rotor that's right by the rotor hat.
Well, i don't think they are worn out. I have extremely poor braking power since day 1 Attached pic my braking pads. I am annoyed of squealing noise when I let off gas pedal. Either pistons are stuck and can't pull pads back or it's vacuum booster.

For a car that has not been used much, it could be that the pads have not been properly bedded. Correct shapes for the Pagid RSC1 (for the 488) are 4580 front and 4581 rear. The Pagid pads do not come with the pad wear sensors that are included with the OEM Brembo pads, so you need to take the existing ones if they're still usable - Brembo does not supply the sensors separately for the Ferrari pads.
Those pads look new! You'll get brake squeal with these brakes. Either they are not bedded in correctly and rotor is glazed up and pad material transfer is not optimal...or... some one detailed your car and sprayed tire shine on the tires and hit overspray on the rotor. Tire shine will attach to a ccm rotor.
Hard to tell from your photos but the photo of the 2 pads in the caliper the one pad on the right looks considerably thinner than the other pad. That's not right if i'm looking at this correctly. Have you checked your caliper pistons operation?
That is my another concern regarding that circle surface around wheel hub. Have attached photos from same rotor. It's not symmetrical, some place its wider another place it's looks like non touched at all Maybe "cut" pad on that area? Bedding-in procedure was performed few times according to Ferrari/Pagid/EBC manuals Squealing goes away for 2 days and comes back. My main concern is still why noise from NOT braking(releasing pedal) comes back. I do not use any chemicals or tire shine. Only water on wheels and high pressure air to clean. Have attached few more photos. Caliper pistons have not been checked. I doubt something can happen at such mileage to them
Interestingly enough just had my final "free" service from Ferrari on my "new" to me 2018 488 spider 15k miles. Brake fluid changed. Practically locked all 4 wheels when I left the dealer. Definitely feel much tighter and responsive. I believe all they did was the fluid to the brakes but hmmm....
Recently bought a pista, and can completely relate to some of the comments. My first drive in the pista i was exiting a freeway onramp at 70mph and the car wouldnt stop, thankfully it was a huge onramp. I took the car in to Ferrari to dig deeper and they took me everything is perfect after a diagnosis, even said car had a break flush last year. Ive heard mixed things such as the pads need to be warmed up and this is how 488 brakes are. Mine feel very hard to press. I came from Porsche ceramics and never felt this way. One of these days im going to go 80mph and cautiously slam on the brakes and see if they really do work right. Ferrari checking everything sort of put my mind to ease though. If a booster was giving out, or had a leak would it throw a check engine or fault?
In theory there has been a recall supposed to address the booster issue - it's not a fundamental change though, a new cap on the brake fluid tank (supposed to avoid excess pressure in the tank, that could lead to fluid leaking into the booster, as far as I understand), and a more severe monitoring of the brake fluid level. There are separate issues though : one is the documented potential booster issue (object of the recall), the other is the subpar performance of the OEM Ferrari braking system on the 458 / 488 / F8 (the 296 seems to be better).
Have done bedding-in process for few more times using different methods. Squeaking when breaking went away. However, squealing when driving idle (no acceleration , no braking) noise is incredibly loud. And it gets louder with more speed.
