FF - CCM brake wear light

This light just came on my 2014 FF, 26k miles. Pads look fine.

I did have the wheels re-powder coated a day ago. Wonder if in that process, they knocked the pad wear wire.

Anything else I should consider before putting up on the lift?

 

Inner pads wear much faster than outers. So unless you’ve inspected the inners, a cursory examination of the outside pads is not enough.

I can’t remember the mileage but my rear pads were toast at a much lower mileage than you have on your car. It was the inner pads which were worn.

Apparently, too much use of stability/TC wears the rear pads out very quickly.

These came on with mine too, and the dealer will recommend you change all discs. However when I had the actual discs and pads checked (and weighted) by the same dealer, they’re all fine. Apparently it’s an ECU thing which has an algorithm that calculates the brake wear (not sure if it is based on the number of times you step on the brake pedal or if you keep driving in a certain mode like wet).

There is no way the discs (assuming the pads are fine as you mentioned) should be worn down to the point of replacement with that kind of mileage unless the car was tracked / driven very hard.

 

What was the outcome of this for you? I somehow don't think Ferrari can set the wear amount in software. Maybe reset it to zero which they likely would not do since they have wear and its a safety thing.

 

Has passed all tests including weighing and inspecting brakes, except for annoying CCM warning light. The ECU’s estimate of brake wear does not correspond to the actual brake wear - solution suggested is to change the discs, which is not a cheap solution for a software issue.

Mine just checked out fine as well. They said they can’t reset the morning light. Do you know whether or not this can be done if you have a Leonardo?

 

I haven’t asked around. Please let me know if you find a solution!

 

The car is going to get looked at again later next week. The long time Ferrari mechanic here says he’s never run into this issue, so he wants to check the brake pads. I know there’s plenty left on there, but he believes even if it is reset it will just light back up again. I will keep you posted.

 

It should be possible to do a reset and see. CCM is not the only option out there. What if the owner decides to change to GiroDisc?...It's now available for this car since last year.

 

Had my FF in to get the CCM light/brakes checked out. Prior look said plenty of pad. He said there is a timer/wear built in their indicator. I am at the 10 year mark on age of the car. You can re-set the CCM light. He stated recommended service is to remove discs, wash, and then weigh them. If within acceptable parameters, then put them back on. My car has 26k in miles. I passed on the disc treatment service.

 

i had to change my rears at 39K miles...no light came on

 

Yeah, I was told rear pads wear down quicker compared to front due to the brake's role in traction control, etc. Interesting re: warning light. My 2013 458 has never had light come on due to "age" of discs.

 

Thanks for the additional info. Did you manage to have the light reset?

 

You don't have to take anyone's work for it. Just take her out for a short drive. Stay off the brakes and give enough throttle to partially slip the rears in a couple corners. Use the trans to slow and keep off the brakes. Take her in and touch the front discs (be VERY careful). They will be cold. Touch the rears and they will be anywhere from hot to really hot.

Try the same with every setting of the manettino and you will find that only in ESC OFF do the rear discs stay cool. I have learned to drive in this mode when tires and road surface permit. It saves unnecessary wear and is a blast knowing the real strength of the drivetrain. Humbling is the word that comes to mind.

 

Picking up this afternoon, but he said it will re-set.

 

They remove brake discs and clean. Everything weighed out just fine. Brake pads are fine. All they have to do is reset the light on the Leonardo.

 

Thanks for the update! Was this at a Ferrari dealer or independent?

 

It was independent, but I confirmed approach with dealer the following (which my independent said as well):

The brake sensor has an algorythm in it that measures age, brake usage, etc. It will eventually go off at some point for a one or a variety of these reasons. But, it does not necessary mean your pads or discs are bad in any way. So, the recommended approach by Ferrari is to check pads (if okay), pull rotors, clean, weigh and measure rotors and make sure they are within acceptable factor specs.

My pads had plenty and my discs were very healthy.

I am sure you can reset the CCM warning light without doing any of these things if you want.

 

Thank you very much! This is very helpful

 

Hi what would be a average level for the discs at 27k miles? Looking to purchase an FF and don't want to be hit with replacement costs in the first year of ownership

 

Welcome to the forum Chris. Don’t sweat the pad change - it’s about £1100-€1200-$1400.
You can obtain a computer readout before purchase to check the disc wear and pad wear.

 

Thanks for the reply, I've had an inspection done and they have come back with 80% wear to rear discs and 75% to front after 27k miles asked to have the disc weighed to confirm. Just wondering what you expect as normal wear rate at that mileage

 

Ferrari claim a disc life of c.80k miles. At 27k miles, I’d expect the discs to have 80% and 75% life left, which is the inverse of what the computer readout is telling you.

We bought my wife’s F12 with 25k miles on the clock and the front discs were 15% worn and the rears were 19% worn.

 

My official dealer Kroymans said a few days ago that my discs (92% +95% worn) and pads should be replaced, which would set me back around 18keuro, which I consider a lot of money. My car has 90kkm (75k by me; 15k by former owner) and I 'never' break in the sense that I always keep quite some distance and I anticipate eagerly. So I expect that my discs are fairly OK. However, I have some remarks and questions:

1) Kroymans says that if I have the pads only replaced and have the discs replaced later, I will have to renew the pads again. Does that sound familiar to you?

2) Kroymans confirmed that the wear indication comes from some algoritm and I guess that it is programmed to always be on the safe side, so I think I have still some time left to renew. And there are ways to measure the actual wear. Info I couldn't find on FC is that the front discs may loose 300 grams max (weight when new indicated on the discs) and may be 36,3mm thick minimum (indicated on the disk); rear discs may loose 70 grams max and may be 31,5mm minimum. So I guess I just take one front and one rear disc off and weigh and measure them. Is this a way to go?

3) GiroDiscs are imported in The Netherlands and I can get a complete set via brakes-shop.com for 5,5keuro which would save me a lot of money. However, the site states "These GiroDisc front rotors are a direct replacement for the OE disc however a different brake pad with an annulus (pad swept area) of 66mm or less must be used. This is done to keep the rotor weight at a reasonable level. The necessary pad shape is FMSI 1405 which are very common and found on the Nissan GT-R, Cadillac CTS-V and most AMG Mercedes equipped with 6 piston calipers." So, as has been mentioned by others on FC I cannot use the 'standard' Brembo pads, but I have no clue which pads I should then use. Does somebody have a parts nr of the pads I will be able to use?

Thanks for your attention!

Best, Wieger
