What kinds of ceramic brake rotors are there?
The industry differentiates between CCB discs, which are manufactured by Brembo SGL (Porsche PCCB, AMG-Mercedes, AUDI). They feature a thin, but hardened top layer. This layer protects the ceramic rotor from wear, making the brake pads the main wearout component.
The second kind are CCM rotors (Ferrari,Maserati), still using outdated technology, these discs do NOT have a hardened top layer and thus wear extremely fast.
Can REBRAKE refurbish both kinds of ceramic rotors?
Yes, because the basic structure is the same. Although we provide a hardened top layer for all brake discs, because we only produce state of the art. The surface is made from silicon-carbonate, and at 90-110 Vickers, is even harder then the OEM parts at about 70 Vickers.
Are refurbished brake rotors under warranty?
A lot of customers believe, that the new layer, that is applied onto the worn rotor, could brake away under high stress. Due to the pyrolysis infiltration, which creates a strong structural bond between the two materials, this is not possible.
This is the reason why we grant you warranty of 12 month for the structural durability of our work.
Do refurbished discs work as well as the OEM parts?
Yes they do! We have tested our refurbishes rotors on the racetrack and the road. During the stress test, 20 emergency braking maneuvers, from 180-0 KM/h were performed. We have not experienced any problems during this test.
How long do refurbished brake discs last?
Because of the improved degree of hardness, the lifespan of our refurbished rotors is equal, if not better than OEM. In the best case they can last up to more than 100.000 km!
Compared to a new OEM product, are there any drawbacks when using refurbished rotors?
All brake rotors are x-rayed, weighed and balanced before they are shipped out to our customers. It is also very important, that only new brake pads are used as soon as you install new or refurbished rotors, because used pads can contain contaminates that can damage the rotor.
How long does it take to refurbish my used rotors?
The refurbishment process can take about 30 working days.
I depend on my car – is there a faster way to get refurbished discs?
If this is the case, please contact us for further information. In some cases we have, already refurbished, rotors in stock for immediate delivery. We will charge you a core deposit (700,00 € per disc), which we will refund in full as soon as we have received the used rotors.
This way your car can be ready again immediately! If we do not have your specific rotors on stock, we can try to obtain a used set. Of course this will add time to your order!
What is the advantage of carbon ceramic brakes?
Carbon ceramic brakes (often just called “ceramic brakes”) have several advantages, so that today more and more high-performance cars are fitted as standard with it.
1. Reduced fading tendency
A lot less “fading” ceramic brake discs are heat resistant up to 1400°C, where steel rotors can only be used up to ca. 800°C. Due to this ceramic rotors have a much higher energy capacity and are a lot more durable under hard use. An overheated steel-rotor will curl up, the pads start to smear and the brake fluid will overheat. All of these things will cause your brakes to fade or, in the worst case, fail completely. However, with ceramic brakes you can even use racing brake pads, with very high friction value, because the additional heat is no problem for a ceramic rotor.
2. Less weight
The weight savings of using lightweight carbon ceramic brakes can amount up to 35 kg per car. The important fact is, that this mass is part of the rotating and unsprung mass. Saving weight at these masses is critical, because they are subject to the moment of inertia. Rotating brake discs, that have to be accelerated or braked, or suspension that moves up and down are subject to the law of inertia. In professional Motorsport there is a saying: “1kg saved at the rotating/unsprung mass is equivalent to about 5kg at the chassis.” Saving up to 35 kg at the brakes alone would mean a theoretical weight loss of up to 175 kg at the chassis.
3. Better Handling
4. Less wear
Why should I invest in high performance brakes?
There are two main reasons why you should: Is your car tuned, has a lot of HP, or are you just a very sporty driver? If one or all are the case, then your stock brakes quickly reach their limits. The heat capacity of steel brakes is very limited – especially on cars without sufficient brake cooling. Furthermore the friction coefficient of metal and steel alloys decreases immensely as soon as it reaches higher temperatures. In essence this means that stock brakes are often very inefficient as soon as they heat up, because of their limited heat capacity and their inability to absorb more heat. All of these problems occur even faster with semi-slick tires, because more braking power can be transferred to the road through the better level of grip of these tires. But upgraded brakes are not only useful to overcome overheating problems, but also improve the stopping distance dramatically, especially when you use your car on the track. With better brakes you can brake later into corners and improve your laptimes.
Is a front-kit sufficient for my car?
It really depends on the concept of your car. Usually the main braking forces are needed at the front axle, due to the dynamic axle load distribution. Therefore one could say a front-kit would be sufficient. But cars who are mid- or rear-engined, or cars whose electronic driving aids intervene at the rear axle, should definitely be equipped with an adequately proportioned braking system at the rear axle as well.
