    Tracked my 360 for the first time a few days ago. Was warned about the likelihood of brake fade and took care to bleed brakes before the track day. Also mounted Pagid Orange pads to minimize risk of pad fade. Still ended up in the gravel on my 5th lap after overcooking the brakes and flooring the brake pedal. For the record, 2 out of 3 360s out there that day lost their brakes (on the 5th lap out) - the 3rd car was resigned to driving 3 lap cycles.

    Can someone please offer advice on how best to prep the stock brakes to avoid premature fade? Did I do a bad thing by putting race pads on the stock calipers/rotors - excessive heat in the system? Will stainless steel hoses and Castrol SRF do the trick? Where can I buy SS hoses for the stock brakes? FYI, it's hot out here - typically 35 degC ambient and 55 degC track temps - and the F1 track I drive on is heavy on the brakes.

    If I choose to upgrade the brakes, what is the best upgrade option available (don't want to pay the $$ for CS brakes) that fits under (1) the stock, and (2) 360 Challenge wheels. I understand that a Brembo GT kit (355mm rotors w/ 4 pot calipers) is available but the upgrade is only available for the front. What, if anything do I need to do with the rears?

    Another mildly related question. Had to tow the car back home after the alternator fried itself after the track session. Has anyone else had their alternator give way?

    Don't mean to go on ranting but I would truly appreciate useful advice on how to make the car a bit more bulletproof. I track my GT3 without any problems whatsoever and my first outing in the 360 turned out quite miserable.

    Club Fiorano, UK Track Club run by Ferrari/Maranello, run a number of 360's on the track. I've been to several days and each car is driven all day by a number of differetn drivers on different tracks and I've never seen a car suffer badly from brake fade and the car's relaibility has been great.

    Perhaps you could drop Fiorano a line and ask if they do anything special with the brakes.

    Weng is experiencing far higher ambient temps in Singapore than the UK guys will ever see.

    Basic upgrades for the braking system should include better brake fluid, lines, pads and temperature management.

    ATE Super Blue (and the amber version too), Motul 600, and of course Castrol SRF are good fluids. I use ATE and Motul- the price advantage outweighs the advantage of SRF, especially if you maintain your brakes on a regular basis.

    Pagid Orange... if you are having problems with the Orange go to the Black 14 compound. I use that on a 3500lb car w/660whp and braking is not an issue.

    More brake ducting. I think that really isn't your problem- I think a soft pedal is usually a fluid issue. If you use the right fluid and right pad the OEM ducting should be enough, but I don't have a 360 (355 owner) so I don't really have a point of reference to go by.

    If, after all that, you still have braking issues, go to the Challenge spec brake system w/ wheels etc. It's a known system that has been sorted out by the teams so if you still have brake issues with that system there should be known fixes too. I wouldn't bother with a street based aftermarket kit if you're having problems with a hopped up OEM street system (after doing all the suggestions I made above).

    Hope that helps...

    The biggest problem with the stock brake system is the fluid. If you were going to change just one component, you would have been wise to flush the fluid and replace with a higher boiling point fluid. The stock pads would probably last one or two track days, then you should go to DS2500 or something like it. The Pagid Orange may be a bit too extreme for the street, although you could change them for each event. The DS2500 is a good street/track compromise pad. Were you running street or race tires? Race tires definitely put more stress on the brake system with their superior traction. Most 360 owners find with street tires they can run Ate Super Blue or equivalent fluid, and DS2500 pads, and do fine. If you run race tires on a brake-intensive track, you may have to upgrade the brakes. A friend of mine just fitted F50 brakes to his 360, but it's not cheap.

    Sorry you had such a miserable time. I haven't heard of alternator problems on any of the local cars that see the track quite often.

    I echo the other sentiments here. The 360 brake system is fine. A couple of relatively easy, and far less expensive, fixes should solve your problem:

    1) better fluid; use Motul 600 or Castrol SRF. The will not boil.

    2) Pagid Oranges are fine, with the right fluid, since they generate mucho heat

    3) get fresh air to the front rotors; the 355 had front rotor air ducting (as does my 550), but for some reason, Ferrari cheaped out on the 360 & did not include them; add that to hot radiator air exiting in front of the front wheels & you have a real heat situation; have some ducts fitted, drawing air fron underneath the front valence & directing it at the inside of the front rotors

    I regularly track my 3,900 lb (according ot the owner's manual, not including the 200 lb driver!) 550 in 90-100 degree F Texas heat, with no problems. I use SRF fluid, and Ferodo DS2500 pads. I never lose braking at all. And I drive HARD.

    Let me reinforce the prior with some concrete evidence.

    I brake hard... hard enough that I evaporated the stock pads on my Modena.
    I put on race pads for the next track day... boiled the fluid.
    I replaced the fluid with Castrol SRF... no more problems with the brakes.

    Just 2 weekends ago I experienced the same issues in my 360 with the fluid...it was boiling after just a few laps on Saturday. I had already changed over to better pads (Porterfield R4) and had what I thought was decent fluid put in (ATE Type 200). Dave Helms was fortunately at the event and provided me with some much better fluid (can't recall the name) and I bled the system Saturday night. The result was that on Sunday I drove harder (after finally building up confidence in the brakes again) and never even felt the slightest bit of fade, even running back to back to back sessions. There are definitely options to gain MORE braking if you want that, but to get the car to the point where you can enjoy it on the track with confidence in your brakes, the fluid and pads are all you need.

    I'm surprised the Ate 200 wasn't good enough, I thought it would have done the job.

    Thanks a bunch for the feedback. I'm running semi-slicks and brake hard. I intend to swap the Pagid Oranges in and out before/after track days. Based on your advice, I'll try out better fluid and braided brake lines before I invest in a brake system upgrade. I run ATE Super Blue (Dot 4) in my GT3 and have no problems with boiling fluid. Maybe the Shell fluid the Ferrari dealer's using just doesn't cut it for track use.

    Any idea where I can buy a set of stainless steel brake lines for the 360?

    3 points:

    1) if you're swapping pads back & forth, are you bedding in your Pagid's BEFORE going on track? You need to do this EVERY time you swap them back in, or else you will not get the braking you want, and you will find yourself pushing the pedal to the firewall every time

    2) the Shell brake fluid is for street use only; it will NOT hold up to hard stops (ask me how I know). Get rid of it ASAP. Super Blue is OK, but if you're running R-compounds or slicks, on a car with that much power, I would consider Motul 600 or Castrol SRF. Expensive...but worth it

    3) brake less hard, but just firmly & smoothly...and then come off the brakes to settle the car; no need to late brake unless you are racing; better to brake firmly & then come off, and then bacl on the power earlier with a settled chassis...plus, less brake heat to deal with

    I have found the opposite to be true. R compound tires are stickier and allow more efficient braking (at least for me), and less engagement of ABS. I now use ATE blue and DS2500 and have had no brake problems since. The stock set up lasted about 30 minutes for me. Things got so hot the wheel center melted.

    1) Yup - bedding in per Pagid instructions every time.

    2) Just came back from the dealer - chief mechanic was mumbling something about how the stock seals may not be designed to cope with fluids like the SRF. What is he going on about? I take it that none of you have had any problems running the Castrol or Motul fluids?

    3) Understand that my braking technique is OK. Hard threshold braking (not too late) and right before the ABS trigger followed by progressive trail braking to keep the nose tracking towards the apex.

    Castrol SRF not available in Singapore - I've just ordered a batch from the US. Still trying to locate the steel brake lines though.

    Thanks. Putting in an inquiry to stoptech to see whether they can ship international.

    Don't believe that Motul is available in Singapore.

    maranelloman,

    Have you tried other pads like the Pagid RS19 Yellow? Are they suitable for daily and track use?

    The orange pagids and stock pads are the only ones recommended by Ferrari but not the yellow ones.

    Weng,
    I experienced the same thing with my 360 with stock fluid and pads. I installed Ferodo DS2500 pads and Castrol SRF fluid and now I can run very hard on the track all day with zero fade. There is no need to go to bigger rotors and calipers. The DS2500's are a good compromise Track/street pad. They squeal a little sometimes but hold up to a full track day. I don't want the hassle of switching race pads in and out every time.

    I'm running Pirelli P-Zero Corsa's 235/18 f, 295/18 r on Challenge rims.

    You may want to try: www.movit.de

    They dont have an application listed for the 360, but the company could probably take care of your particular application.

    No, I have not. But I have had very good luck with the Ferodo DS2500's. And Mitch Alsup, who also posts here & who I know tracks his 355 hard has as well.

    Just for the record, I use DS2500 Ferrodo pads. I went through 5 sets last year, getting about 5 track days per set. After 32 track days the original rotors were toast. I consider this pretty good rotor life for tracked cars (driven as hard as I drive them). DS2500s are streetable down here in Texas winters.

    I use ATE super[Blue/Gold] and flush it 4 times per year (not bleed, a whole system flush). This fluid and the DS2500 pads are sell matched to each other, and my braking <ahem> events have gone away since arriving at this setup.

    I routinely chase down, pass and lap F360F1s on r-compound tires in my F355B on street tires (S03s).

    Considering that the F355 brakes are not as big as the 360 brakes rotors, and that the 360 is lighter than the F355. I can't see any reason to need bigger brakes on a 360. However some air ducting might be appropriate. The 360C cars have a nice little Carbon Fiber scoop that mounts on the lower a-arm and has a duct blowing air on the caliper and rotor. I would try better fluid and pads first, then if braking is still an issue a set of these before trying more expensive options.

    Note: I have noticed the load on my brakes has gone down as my driving skills improve.

    Phil,

    I've attached a description of the Orange and RS19 Yellow compounds.

    "RS 4-4 ORANGE

    This compound has a very good fade resistance and a higher average friction value than the RS 4-2. It is rotor friendly with a predictable, non-aggressive friction behaviour (stable torque). Fading resistance up to 560°C (1.050°F). It is a very good rear compound for Touring Car applications in combination with RS 14 front pads. It’s main application is Porsche 911 racing. It is used on either Short Track or Long Distance; also for front and rear axles. It is also used on BMW Showroom Stock, all other Touring-Cars and Single- Seater up to F3.

    RS 19 YELLOW

    Best compound for endurance racing on the basis of the RS 14. A slight reduction of the friction value improves the modulation. Nevertheless, the friction value is enough for cars without power-assisted brake system and ensures comfortable low effort on the brake pedal. Constant temperatures up to 600°C (1.100°F) are possible. The combination of friction value, fading stability and low wear rates on pads and discs realised with this pad compound is unmatched up to now. Due to its outstanding wear rate and driveability also used at many sprint races. Application: All endurance racing cars from group N (Speed-WC, Grand Am Cup) up to GT and Sport-Prototypes. A multiple winner of Daytona 24h, Le Mans 24h, Sebring 12h, Spa 24 h, Nürburgring 24h, often with no pad change and usually no disc change. "

    Based on a graph I've seen from Pagid, the RS19's have better cold and hot temp friction characteristics than the Orange. They cost more, last longer but are a bit more rotor hungry. I've been using them on the GT3 and they're the best compound I've tested to date - particularly with the temperatures that we see at Sepang.
