Rebrake PCCB Refurbishment - 997.2 GT3 - Page 2 - 911/Carrera GT - PistonHeads UK

Has anyone got any first-hand experience of Rebrake and their ceramic disc refurbishment service? I understand JZM offer PCCB refurbishment via this company too. I was advised today that my rear disc thickness on my 997.2 GT3 is now 27.8mm (min thickness 27.7mm). I’m surprised that the rear discs have worn at this rate TBH since the car has covered 34k miles and has only been used for occasional track days. However, as documented at length, PCCBs of this vintage are far from bulletproof. Anyhow, in the not too distant future they will require replacing and Rebrake would appear to offer a cost effective option for rejuvenating my rear discs, as and when they are finally worn to limits. Any recommendations out there for this company?

They seem good, but had bad issues, now seem resolved. “Delivery times – important information!!! In the past, we have unfortunately experienced some delivery delays. The company, that owned the patent for carbon-ceramic brake discs refurbishment and produced for us, has turned out to be an unreliable partner many times. In June 2019 REBRAKE bought the technology as well as worldwide marketing rights and took over the production. After two months, we can now reassure, that the cycle time of appx. 30 workdays can and will be met”

How on earth have the disks worn out after 34k miles and few track days?

I remember these being marketed as lasting the lifetime of the car, obviously not.

If you drive on track with the old PCCb's and PSM on, the systems brakes the rears to help a over driven car, hence you see many cars with worn rears over fronts, this causes heat and more wear which then needs 2 cool down laps. the cars been over driven and the system has had to brake the rear of the car to keep it on the road, it's that simple. its was a basic design in the 997 and now they call it PTV and is just as bad and should not be on GT type cars imo.

I think solutions include to turn off all support systems when on track....and ideally uprate the diff to a 996 type diff. Also as the std diff weakens with use the car will lean more and more on rear brakes when the systems are on.

I tuned ABS, ESP and traction control on some very heavy cars equipped with PCCB. I remember being shocked at how slowly they wore. I was sometimes going through a set of pads a day, the center caps of the wheels melted. But I never needed to change the discs. Cool story, bro!

Interesting, does the 997.1 GT3 have the same system? I've old got a sport button. Bert

A sweeping assumption in this instance but I can’t agree that over-diving my car has resulted in any premature wear. Notwithstanding that the car has been subject to very few track days, the conditions have always been ideal and I have driven either with SC off or both TC + SC off. If I’m relying on the aids as a safety net in the dry, there’s an accident coming! The limits of the car in the dry are so very high, I can trust myself to drive comfortably within them. Note both front and rear pads lasted for 30k+ miles before requiring replacement and neither triggered the wear indicators. I was therefore very surprised to hear the OPC Service advisor tell me that my rear discs needed replacing! I queried this with the main Porsche tech, who also said there’s a lot of confusion over PCCBs, particularly regarding visual wear indicators etc. In the end he said there was nothing to be concerned about. When I checked I was told that the rear disc thickness measurement last year was 27.8mm too. Since then I have done 4K miles, including a very spirited 2500 Mile euro road trip to Spain (where the car got a good workout and my wife complained about the smell it was making on the tortuous downhill runs) and a Donington Park trackday. So apparently zero wear since last year’s MOT according to measurements taken during this last ‘health check’ as part of it’s annual MOT. I question the measurements taken as well as the ultimate longevity of the PCCBs, which I why I was asking around to see if anyone has actually had their discs refurbed by Rebrake (previously SICOM). It appears not so far. One thing is for certain, I don’t intend on buying 2 x replacement rear PCCBs rotors anytime soon

Rear brakes do take a pounding on the 997s (and later ones I guess). I had a pair of rear PCCBs refurbed by Sicom (rebrake’s previous incarnation) a few years ago on a 3.8rs. As said the actual product was perfect. Dealing with them was less than perfect. And just to highlight that rear wear is normal, I also bought a 4.0rs that had heat discoloured rear callipers from all the work they were doing on track. These ended up being replaced with new ones.

Thanks for the feedback.

The 997 diff is the weak link and the electronic aids are programmed to assist it’s short comings whether turned off or not (according to rennlist threads I’ve read). So first thing, is your diff working, at the mileage you quote above I doubt it, get it checked out if not already done so. If it is worn out upgrade to either motorsport diff plates or a guard transmission diff. I personally also change ramp angles to 40/60 (same as 996) this really does help with the rear brake compensation issue the 997s have. I now get double the life out of rear brake pads now I have 40/60 ramp angles. Out of interest how worn are the front discs?

Cunno, Thanks for the advice on the diff. As you say a known weak point so worth looking into as it can affect the rear brake life, as well as stability etc. Re the front discs they were measured at 34.1mm (min thickness 33.7mm).

Thanks John (Cunno) Good information. I had a set of PCCB's refurbished by SICOM. For me they were good ... of course ST's in Porsche fit are a completely different proposition ...

I normally drive on track with TC off but last week I was at a drenched Goodwood and with a passenger on board, left it on. Between Fordwater and No Name I could feel the rear brakes grabbing. (I will also get my diff checked (30k miles)).

Paid an exchange Depsoit and still can’t get them to pay it back.

In that case sounds like the new partner has not solved the issue. It would seem to me that the inefficiency (eg of returning deposits) is not an issue of supplying partner but more general admin in the owning company (which is still the same)

Exchange is a bad idea imo anyway esp if you only have worn disks and want to do preventative work over some of the really nackered chipped disks you see. I would want my own disks back, and they now state 30days. Will get mine done over winter and then also no money up front then to try and claim back.

I thought PCCB discs are weighed to measure wear rather thickness?

SFO said: I thought PCCB discs are weighed to measure wear rather thickness? The brembo ones ie Ferrari/Mclaren/Corvette ones are weighed I think. The Porsche ones from SGL have a measurement tool these days for rotor thickness.

Sorry, pedant mode on ; The Carboteq measuring device avoids the need for removing the rotors for weighing them and and measures the interlacing and oxidisation of the rotor rather than thickness ; https://m.youtube.com/watch?v=asnGXOmQsYU

I know people who had their car on ramps for months waiting for their discs to return...there are risks both ways. Would be good if the process is now fixed - however they have a big mountain to climb to regain consumer trust (as I do not believe the problem was just at the partner factory).

Or you could talk to Steve at JZM about ST discs. Weight ? Thickness ? They can be skimmed up to five times if they get chipped and they are fantastic. Great braking performance, very good cooling, very long life, big savings on brake pad wear ... Porsche really should fit them as standard ... but then they would not profit from replacements .. what a shame.

I also need to fix my ceramic rotors.. Any idea?

Could have a look at these guys.. https://www.redisc.si/en/

I was very happy with the SICOM refurbed discs on my CR and am now having my ST discs first skimmed ... hopefully with no problems because there are no guarantees

Hi, thanks. I have already contacted Redisc.. My discs are already in the process. I will let you know how it goes.

Cool, look forward to seeing how you get on… How they were to deal with and end results.

Hi, just seen our name here. If someone has any question, please ask us Have a great day

Thanks, ... I see on race cars Direct that the cost is Euros 1800 +vat ... is this per disc ? Also, do you offer an exchange basis with a deposit per disc repayable when the old discs are returned in refurbish able condition ... or ?? How does this work Thanks, Chris

Hi Chris, I did not see this post and would like to apologize for that. So if anyone wants to refurb their discs, then we arrange for the shipping (or you can do it yourself). We need 30 - 45 days to do the process. in the meantime, I do inform you how everything is going and send you pics. We do not take any deposits. Payment is done, after discs are done and you get all the info. For the replacement: we can offer - if we have on stock. It really depends on the car /discs. We have lots of Ferrari 458 and 997. Pricewise, some discount is available, price is per piece.

What are the chances of being able to take them apart and replace the bolts if they are in this condition? Thank you

Hi, we can take them out. Really depends on the situation. If you do not mind, please send me pictures at [email removed] or Whats app +386 31 561 725 and we discuss your case.
