Controlling brake rotor temperatures is the easiest way to improve lap times, by allowing the brake pads and rotors to operate in their optimal temperature range, therefore increasing the frictional coefficient and decreasing stopping distances. Rotor and pad temperatures greatly affect the braking performance of the vehicle.
Most race and semi-race compound pads require a temperature range of 300° to 800° C (572° to 1470° F) for optimal braking performance. This Brake Temperature Paint delivers the widest temperature range in one bottle. Temperature readings ranging from 0° to 800°+ C (0° to 1471° F) are displayed over a six color change from cold to hot.
Simply apply paint evenly to a clean, grease free surface, allowing to dry to touch, and to remove used paint off of surface, use a disposable towel or rag and wipe off remaining paint material. Brake temperature color code guide on the bottle for quick temperature reference.
Know your brake temperature and use it as a guidline for compound change/modification to improve the longevity of your brake components and lap time.
Price: $64.95/1oz bottle. Good for approx 30-40 applications.
Assembly Procedure - This is for Alcon Extreme brake kits with the semi-gloating style Bobbins.
1. Insert bushing into the aluminum hat and press in.
2. Insert wavo springs into location diameter on every other bushing so that there are an even spread of springs. Ensure correct orientation of spring (see fig.1).
3. Insert bobbin into bushing and push the bobbin through so that it engages with the disc.
4. Push bolt through bobbin.
5. Apply a small amount of thread retainer, (Loctite 243 Blue) enough to cover 2-4 threads, to portion of bolt protruding from the disc. Hand assemble a nut onto each bolt so that they are finger tight.
6. Tighten the nuts (not the bolt) in a start sequence. Tightening Torques: M6 10-11 nM or 7.4-8.1 ftl-lbs
7. Apply a small amount of red paint to the end of each bolt to indicate that the nuts have been torqued correctly.
8. Ensure that all the springs are located under the bobbin flange and located securely in the recess of the bushing and not trapped between the bobbin flange and the bell.

Torque Specs for NAS Nuts: 120 in-lbs
Special Notes: Note orientation of mounting hardware in figure 1. Install Bellville washers on every other bolt, and note washer orientation as seen in figure 2.
Refer to the to the diagrams below. Note the orientation of the Belleville washers. They are located on the Bobbin. The Belleville washers are designed to provide spring force against the rotor to prevent rattling of the rotor and float capability.
Note the parts used for your rotor installation.
1. Insert bolts (1) into Bobbins (2)
2. Install Belleville washers (3) onto bobbins (2) as shown in figure 1.
3. Insert Bolts/Bobbin/Washer assembly into the rotor as shown in figure 2.
4. Install hardened washers (4) onto bolts on the outside of the rotor
5. Place hat over bolts. The hardened washers may create a gap.
6. Install jet nuts onto bolts over hats and tighten loosely by hand.
7. Torque jet nuts in a star pattern to final torque. (120-in-lbs).
Two types of bobbin are available:
