Brake pad wear on FF

Rear one is gone after only 10000km. No track day at all. Guess driving too aggressive and hard cornering in comfort mode was the reason. Anyway, i will keep driving hard.

10,000 km = 6,213 miles.

not much at all!

 

that is pretty rapid wear.

The stability and traction control on the FF in Comfort is relatively aggressive, coupled with the way that system works, the amount of torque from the engine and the weight of the car, I can imagine the rear brakes get worked.

Did you get a brake wear warning, or was this a visual inspection?

We have 6K on ours - driven briskly, but more in Sport (Comfort on highways) - curious how that manifests into rear pad wear. Ours are still relatively fresh (though well, well bedded which makes a big difference!)

 

Can you tell me how to bed pads? Warning light came on and I did visual inspection.

lots of threads here to search on CCB brake bedding, especially in the 458 forum. There are a lot of differing philosophies.

here is mine

1) just know you'll need to get the brakes hotter than you think is sane, and then be able to let them cool all the way down to ambient.
2) on a clear, dry, open, safe (etc) piece of road, accelerate as fast as you can go (100mph?) and pound the brake pedal as hard as you can, get into ABS, and slow all the way down (this is good practice for max braking;again make sure it's safe and nobody is around you)
3) repeat the accelerate/brake cycle 6-7-8 times. with new pads, you should clearly be able to smell the brakes
4) drive slowly and gently on the brakes, and let them cool down to ambient (either park and let it rest or take a highway cruise to get a lot of airflow over the brakes to cool them).

If you're only changing the rear pads, you "might" be able to "re-bed" the fronts in the same process....hard/impossible to do on race pads, street pads you can try. The bedding process physically seats and sets the pad/rotor surface, but the heat cycle also changes the pads chemically/structurally. If you have ever felt your CCB's aren't working, chances are they are not warm enough or more likely the brakes were never properly bedded for max performance.

 

Correct me if I'm incorrect but on #2, I think you do not want to come to a complete stop- correct? Go from like 100 to ~10 and then get off the brakes, and repeat several times.

 

29,000 miles on my FF with no brake problems and I drive it like I stole it. No track time though.

Previous bed in suggestions are spot on. When you first replace the pads be VERY VERY careful, the brakes barely work at all until you get them bedded in! Changed pads on my California after 22,000 miles and 2.5 hours track time at the Mid-Ohio race track. That gobbled up about half of the brake life. I would bet any normal Cali driver would get 45,000+ miles on a set if there was no track time at all.

Very interesting. So it pays to run in sport mode if you want to drive aggressively.

 

Is the wear even between both sides?

 

Good catch, sorry - I usually go down to 20 or so and go again. However, the idea is to build the heat and then let them cool down. It's the heat, not the stop-and-go. You really need to pound on the brakes, very hard and steady pedal pressure.

OF COURSE - do it someplace safely...and brake in a STRAIGHT line....if need be you can keep the speeds lower, just really get the brakes worked.

 

As I remember the Ferrari instructions that I received from my dealer the first bunch of stops were from less than 35 MPH because the brakes would be VERY unreliable at first. There were a bunch of stops, then a driving cool down period, then a bunch of stops from higher speed (45 or so) then cool down then a bunch from 60 or 80 ... maybe I need to ask for that detailed instruction set again

Not perfectly even I would say but yes one can say it is almost even.

 

That seems like exceedingly low mileage for a CCB life. I would be a bit upset about that and use the W word.

 

Well, I finally took a CLOSE look at my brakes, 28,000 miles and the fronts are OK, the rears are just about gone! The right side of the car is significantly worse then the left side so I ordered a set of rear pads from my dealer. I switched to winter tires also and after maybe 15,000 miles the rears are near the wear bars, not in them, but pretty well gone. The fronts are really worn on the inside edge! The right front is even showing cord along the inside edge. So, I am having the rear pads replaced and having the front alignment checked. More news when that work is done.

Rick // When was your last annual maintenance (which should have caught the brakes and alignment issue)?

 

So you have aroung 15K miles on your summer tires? That's pretty amazing. I feel like I'm seeing similar wear, and am really amazed at how long the tires are lasting (pothole damage notwithstanding). If I got 10K on a set of tires in our 612 we were lucky, often more like 6K.

Definitely curious about the brake pad wear. Just got our car back from its first service at 15K miles, and no note of wear on the service forms, but I'll have a chat with the shop to see if they have any comments to add..

 

15K on these tires is normal. On the wheel alignment, a good heads up. After all these years, I still neglect to look ACROSS the entire tire to check wear, being content just to inspect the outside part. A no-no.

The asymmetric wear on the right rear is interesting. Can I assume that you are making more hard left turns than right? I'm thinking that normally in a left turn the e-diff will apply more power to the right rear wheel to help you around the turn, but if there is an incipient slide, the brake will be applied there instead. (Of course I could have it completely backwards).

 

I have 12K miles on my tires and plenty of meat left

 

I am quite amazed too, need to double check my figures I guess. But with 28K on it and with the snows on since last the beginning in October 2012 the numbers work. I am used to getting 6K out of the rears on my California with PZeros. PZeros on the FF too. The Michelins on the Cali are lasting much longer but they are stupid slippery.

I will check my records to see when I got my last oil change.
