This 997 GT3 gets a lesson in Brembo Technology

The Porsche 997 GT3 was made to race. The enhanced model of the 997 is built to beat opponents on the track or road. With a faster engine comes the need for better performance breaks. That’s why this GT3 customer contacted Ahmed (Ahmed@vividracing.com ext. 231) our sales guy. He ordered the Brembo Iron Tyoe III Rotor Conversion with Performance Friction Brake Pads. Once this customer recieved his Rotors, he noticed that the hardware seemed loose. This was the customer’s question to our sales guy.

“The Brembo rotors and PFC brake pads installed fine. One question on the rotors. I noticed that some of the hardware that secure the discs to the aluminum hats appear to be “loose”, but a printed sheet in each shipping carton said not to tighten the hardware. Were the rotors assembled by Brembo? Attached are several photos to show that the hardware appears to be tightened a different amount depending on the location of the fastener on the hat. I don’t want to run the car at track speeds if the rotor hardware is installed incorrectly. Is the brake torque on the discs carried by the fastener hardware?”

This is question is more common than one would think. We reached out to our friends at Brembo to see what the exact protocol is and what a good explanation for our customer would be. Here was his response,

“Do NOT to touch those bolts! That is the way they are supposed to be. Here is a paragraph from the FAQ section on our www.racetechnologies.com web site: Some of the bushings in the two-piece disc assembly seem to be loose.” 

“The two-piece disc assemblies utilize a floating disc. The mounting system of the disc is designed to allow a specific amount of float in both the radial and axial directions. Brembo has engineered special springs that are used on every other fastener in order to slightly preload the assembly. This has been done to prevent excessive noise from the system during street use, while still maintaining the benefits of a floating disc. These springs can be seen when looking at the backside of the disc. The small screws on the backside of the disc are properly torqued during assembly and utilize thread lock compound to prevent loosening. They must not be tightened further.”

This a great lesson for anyone new to Brembo or those who are trying their hand out at the two-piece rotor set.
