Brake squeak again- bedding them is only temporary- HELP!

Wash them with water. Do not use silicone product as these may damage the rotors and pads.

The squeeking will get better for a while then get worse again.

 

The service manager told me the same thing. Embarrassing in stop and go traffic or parking garage. Happy with no brake dust however the rims of my 911 with steel rotors would be filthy.

 

Speculation on my part, but perhaps 65 to 20 mph isn't fast enough to generate the braking force required to remove surface glazing. I've read elsewhere that people stomp the brakes @ 80+ mph to improve bed-in.

BTW, I had my pads changed shortly after I took delivery, and apply firmer braking pressure to avoid squeal. Someone once told me the carbon ceramic brakes are meant to be used to quickly slow down, not brake like a limo driver.

 

70mph then a very hard brake a couple of times does the trick, but needs to be repeated regularly.

Ive not owned a car with ceramic brakes before and I had a scare when I used the car for the 1st time after 4 weeks in the garage and the first time I needed to brake I nearly over shot the junction. Take care to bed the brakes in if the car has not been used for a while.

 

I've read the optimal operating temperature for carbon ceramics is higher than regular iron brakes, so its a good idea to warm them up with some moderate braking before trying to quickly stop.

Markjr's story eminds me of the first time I borrowed a friend's 1950s-era car in college. He told me the brakes were "worn." I almost peed my pants at the first traffic light when I pressed the brake pedal and it went almost all the way to the floor, and I didn't roll to a stop until 1/3 of the way into the intersection.

 

I would tell you after somewhat warming them up, 80 mph to stop and braking hard enough to be in the ABS the ENTIRE TIME! Works every time. 42,000 miles + over two Cali's and this procedure worked every time and lasts quite a while. Don't be a woosie ... get it into the ABS to get the max wear to clean them up.

I always drive fairly gently until the engine oil gets fully up to normal temperature (nothing to do with the brakes I know that ), then start having a bit of fun. That initial drive usually includes some braking so the brakes will be slightly warmed by then. If I have had squeaking I do a very hard stop from 60, and pull out listening to them, if there is any squeak left I do a full ABS stop from 80 (while in Michigan if the Ohio Highway Patrol is listening ... in Ohio if the Michigan cops are listening ). That always seems to work.

At one time I had the break-in procedure for new pads, it is particularly brutal on the brakes to get them seated properly, you would be very surprised!

FYI.

My car had 10 kms on the odometer when it arrived for pickup. My salesman assured me the pads would already be bedded and the brakes quite capable of performing a "nose plant". They work just fine. He was right.

I am pretty sure the factory beds the pads when they test drive each new car. These cars are meant to be driven very fast and not all customers know how CCM brakes work. So they certainly don't want a customer to have a "loss of braking" accident the day they pick up their new car! Easy enough to do with the Fiorano track being right next to the factory. It would account for a few of the 10 kms. Base on current output, on average the factory would complete about 30 cars per day (250 work days). If it takes 10 minutes per car, it translates to 5 hours of the track for 30 cars (Ferrari would soon need an extra track if they increased capacity ).

New replacement pads are a different story. I suspect the factory does not expect owners to need new pads unless they track their cars, in which case it would be easy for them to do several high speed stops to quickly bed the new pads at the track. I think if you do several consecutive stops, the pads would be bedded for good. If you only do one or two stops, you have to re-do the bedding occasionally because the bed that you lay down is too thin. CCM pad manufacturers all recommend multiple stops from high speeds for bedding. So you may want to check with them for what they recommend.

Maybe it's time to book some practice time at your nearby race track.

 

Had similar issues.... followed Rick's suggestions and brakes are now silent... question is for how long???

 

+1 on the race track suggestion

wow, 10kms is about as low delivery miles as I have seen or heard. Our cars averaged around 60, which I'd imagine is a mix of factory test drive, loading, unloading and dealer PDI test driving.

While the factory test drives the cars, and dyno runs each engine, I have yet to see any of our new Ferraris come with properly bedded brakes, though compared to most cars poorly bedded CCMs still stop well.

My understanding is that almost zero new cars out of the factory today are run at Fiorano, the "road test" is purely a functional test on local roads on a predefined route. When we checked the computers on each car at delivery, it matched the km on the odo, max speed was 100 kph. (will defer to the 101 threads on break-in and brake bedding).

Brake bedding is easy....as outlined above....CCM's really need to be warm and stomped on to get max performance, I'd speculate that (many) brake complaints are from improper bedding or soft braking habits. CCM's reward hard initial pressure, which is the opposite of how most of us were taught to brake (on the street, anyway).

 

There is nothing wrong with "squeaky" brakes, especially CCM. Carbon brakes like to be hot. They wear on the number of applications not energy absorbed. If you brake gently when they are cold they will most likely "squeak". So what, it's only a problem if your embarrassed.

I think there was a comment that the factory doesn't think you will need new pads unless you track. This is not true. Although you may never need to replace the rotors (unless you track), you will definitely need new pads at some point. then you will have to "bed" the pads. I do not think that the California's are normally tracked before being sent to the dealers.

 

My back brake squeaks all the time regardless of braking or accelerating. Is this the same thing or should I be worried?

 

CC brakes are never going to be silent. Or at least they're not supposed to. Unless they're squealing like a scalded pig, it's normal. There's no need to beat the crap out of them folks. They only need to be bedded (if at all) if you're going to subject them to track duty. And then, you only have to do that ONCE. Otherwise, you're unnecessarily wearing them out. And if you haven't checked, those suckers are not cheap .

 

I am going on a track day with my Cali on Thursday so I should finally manage to clean the brakes by getting them really hot!
From last time I did it the brake squeal stopped for a few months

 

When i had my '10 in last month the service rep mentioned there is a pad replacement that will reduce the squeaking. He suggested this is for guys that drive the cars less aggressively. I believe he mentioned it uses a different material. May be worth checking out.

 

^^

Yes, that is what I meant to say in my post #4 - I got a different set of pads to help reduce squeaking. They do not completely eliminate it if braking too softly - once the brakes are adequately warmed, one can brake later applying firmer pressure.

 

My 430 carbon brakes some times squeal when they are a tad dirty or dusty. Just spraying the wheel and caliper with hose water washes them out and the noise goes away until they get dusty again. Obviously I never spray water on a warm or hot wheel only cold for me.
