Thanks for the advice JRV - if I were guessing, the most common cause from what you've said would be "improper original break in." I've never driven/ridden or known a 550 which didn't have squealy brakes... Jeffrey - how the hell are you mate - good to see you here too! I hope that 550 is running as sweet as possible! Best Regards Manu | ||

I have several 550 customers and their brakes don't squeal. First I've heard of this. Jeffery is correct that most squeals are caused by vibration. Several things can cause pads to squeal (vibrate), some of the most common are 1) glazed pads, caused from long slow stops that harden pad surface 2) imbeddedness, rust from long sits being embedded into pad surface 3) improper original break in 4) pads vibrating againt the calipers themselves rather that against the rotor In 'almost' every case of Brake Squeal I've ever seen the squeal can be eliminated by the removal of the pads, cleaning of pads & rotors and the use of products specificaly designed to cure brake squeal. | ||

Funny, I have a '97 550 and have never had any squealing problems in any kind of weather or temperature......One of the few high performance cars I've owned where that hasn't been a problem. Brakes are stock as far as I know. Matt, I understand and agree with your statement that the noise is compound-dependent. But I also thought that there was a vibration factor in there too, where the brake shoe vibrated against another component. And that it could be fixed or lessened by putting a dampening pad somewhere. Yes? No? Manu: good to see your name again. Hope you had a Happy New Year! | ||

Manu, again, the squeal is caused by the composition of the brake pad. Change the type of pad, or have one fabricated, and you WILL solve the squeal issue. Just trying to help pal. | ||

550M brakes squeak HORRENDOUSLY.... and as far as I know there's not a damn thing you can do about it - but that's not IMO, a sufficiently good enough reason to be discouraged from the FHP.....The FHP is very serious piece of kit - it makes the 550/575 quite a lot sharper...... it's just a question of whether you can handle the discomfort - Dave (maranelloman) said it's just wayy too much on the road and even I've heard it's just too low at the fron end.... I'd still get it though but then that's me  | ||

Doody...if Ferrari does not sell another compound pad (as they don't make any braking components themselves, they just mark up their suppliers components), I have a thought on what you can do about that squeal. Take a set of used pads, and send them to a pad manufacturer. They will be able to put any material on the metal of your pad. You can try Performance Friction, or Power Pad. Both of them should be able to help you out. These are the companies whose pads I use for racing. And the prices.....you will never go back to your Ferrari Parts dealer again! | ||

Manu made an interesting comment - apparently the previous 575s all suffered from a soggy suspension, which has since been recalibrated (skyhook and computer remapping is cool) - apparently the journalists are all under the impression they are driving FHP cars when they aren't. Should the 'new' suspension actually be revised, then I'd be tempted not to go for the FHP as it simply makes no sense in my driving purposes. --Dan | ||

my 550 brakes squeal like stuck pigs. 1999. no FHP. red calipers instead of stock black, but that shouldn't matter. doody. | ||

Richard, the only reason brakes would squeak is the type of compound used in the pad. If there is an updated brake package (I am not familiar with the package) GET IT!! As brake updates usually translate into bigger calipers and rotors, which result in better braking performance. Actually, after reading again, what you said Kevin said...that is....how do I say this politically correctly....that is one of the dumbest statements I have ever heard from a dealer! So much for politically correctness. Brake squeal comes when the pad hits the rotor. The more metalic the pad, the greater the probability of squealing. I'm sure Kevin is a great guy, but I hope you misunderstood him. Otherwise, I would be VERY cautious about taking his mechanical advise. Just my jaded opinion. | ||

Dan: I just ordered the options for my 575. The dealer, Continental in Chicago, discouraged me from the Fiorano handling package because they change the brakes. And when they do that the brakes squeal a lot. Call Keith at 630.655.3535. He is a very knowledgable fellow. | ||

Doody, Thanks - I read both articles (hence the comment on british mags), but again, I'm dubious as to what EVO knows. I also went through some of the discussion here, but found nothnig definitive. It seems that the dealers are a bit murky on what exactly is changed and what isn't - perhaps some of our brethren across the pond can help? --Dan | ||

Doddy, I am considering hard in trading in my 1999 996 cab into a 550. I test drove a 996tt with the intention to trade in my 2000 996 coupe, and I ended up getting a 360 F1 coupe last year. Still own a 99 996 cab for an everyday driving. Do you think I should do it?? I have been always owning 2 Porsche, now one 360 and one 996. It will be the same story like yours if I trade my 996 to 550. One V8 and one V12 Ferrari | ||

dan, your dealer is probably your best bet. this particular discussion has been done in here a few times, with little to no definitive answer, if memory serves. i can tell you that the FHP was only available on 2000 and 2001 550s. my understanding is that the EVO 575M review (2nd half 2002), and further dicsussions thereupon in their 01/03 COTY issue, had an FHP car. it's different software as well, apparently. the EVO article bashes the standard setup in favor of the FHP, as if they had tested both. doody. | ||

For the 360, the Fiorano package is for Europe only. | ||

Ok - this time it's the Fiorano package. I can't get any definitive answers about what it is, and so I'm forced to resort to (mostly wrong) magazines (and I read the british rags, too!). I'm more interested in the 575, but what is included in the Fiorano package, and does it make any difference? The only definitive thing I can find is that on the 575, the car is lowered slightly with stiffer springs. If that's all, I'd prefer to avoid it as it will be a regularly driven car (albeit on quality CA roads) - comfort is key. If the change isn't that dramatic from a comfort perspective (ie it doesn't become anywhere near 360-stiff, only slightly more so than normal), and yet provides some improvement in high-speed composure (not that I ever exceed 65mph on public freeways :D ), then I might consider it. If it has any bearing, I am *not* going with the F1 transmission. Any input/opinions or definitive answers are most welcome. THanks, --Dan |
