I recently had my 2000 360 on the local track and drove it pretty hard. Late in the day I noticed that my brakes were fading badly. I immediately did a few cool-down laps and called it a day. However, I noticed on the way home that the brakes did not feel right. I was getting some vibration and extra 'texture' to the pedal feel. The car sat idle for some weeks while I was away on vacation. I now took the car out on a short drive and found that the rear brake vibration and such is still there AND now the brakes are also quite squeaky. I am concerned that I may have warped my rear rotors. If so, can anyone give me an idea how much it will cost to replace the rotors? I can have them looked at locally by a good non-dealer, or wait to get the car to the dealer (which is 375 miles away) for the 15K service, which is due soon. Thoughts?

Is your warranty still in effect. I believe it will cover this unless they [the dealer] looks at the RPM history and determines you were on a track. Also are you sure it is only the rear? Most breaking power comes from the front. I think you are looking at about a $3000 repair.

Welcome to the site, I hope you enjoy it.

Sounds to me like it's a warped rotor. A mid engine car works the rear brakes more than a front one does. Combine that with the fact that rear brakes get little to no ventilation for cooling and you can see how they can warp before the fronts.

Sorry to hear it happened to you. But, play hard pay hard! The harder you push a car toward its limits the quicker the components are going to wear out. That's why it's called pushing to the limit... these components are designed with performance parameters. If you go over their limits you have to replace them.

You might want to check into some aftermarket discs if you plan on doing track events again. An upgrade seems to be in store for you. Talk to some of the Ferrari Challenge guys to see what they run and also to others who do a lot of track day events. I’m sure you’re not the first to run into this problem. Someone’s already found a solution, you just have to find out what it is.

Warping discs from everyday use shouldn’t happen. Warping discs from throttling the car on the track is going to happen quite consistently. These are parts that will have a specific life span if you plan to continue to track the car and you need to start calculating it into your yearly cost if you want to continue.

Also, if you go with aftermarket discs and begin to think about slotted or cross drilled, go with slotted. Cross drilled look cool as hell but they crack. You’ll get better performance from slotted and they’ll last longer. Also go with Motul brake fluid.

Just my .02

The rotors could be worped. Just skim then and snadpaper the pads. No need to change the rotors yet.

What I did to my Modena was to replace all the factory brake with steel braided hoses. The brakes becomes better and they last as many laps as you want to drive. The factroy brakes last about 4 or 5 laps and then you have to come in already.

If the rotors are warped they need to be changed. Machining down warped rotors won't help you out. It'll cause more problems than you have now in the long run.

FULLY AGREE!!! Also consider installing front brake cooling ducts to the rotors and use them during track days (close/remove them for street driving).
