EVERYTHING YOU NEED TO KNOW ABOUT FACTS & FIGURES OF BREMBO BRAKES FOR NASCAR CARS
All NASCAR Cup Series enthusiasts have the number of their favorite driver inscribed on their hearts: some love 48 (Jimmie Johnson), some go crazy for 18 (Kyle Busch), others are fans of 78 (Martin Truex Jr.) and still others think the world of 4 (Kevin Harvick).
The only number that has been officially retired from NASCAR is 61, which is the number Richie Evans used before his fatal crash in 1985 at Martinsville Speedway. Evans won more than 400 Whelen Modified races and earned the Nascar National Modified Championship title eight times in a row from 1978 to 1985.
Many believe that Richard Petty’s 43 and Dale Earnhardt’s 3 ought to be retired as well. The same honor should be bestowed on Jeff Gordon’s 24 and number 21 used by the Wood Brothers Racing Team. We at Brembo aren’t sure because some of us think it’s right to retire the numbers of legends, others think the opposite.

But experts all agree on one thing: NASCAR race cars can’t forego use of the brakes, even when competing on oval tracks. To highlight the importance of these components, we have put together a list of 28 numbers having to do with brakes.
0: the times the drivers use the brakes during the race on large size oval tracks such as Indianapolis, Talladega and Daytona for true braking events, except for the lap to return to the pits or for an accident. But the brakes are used on these tracks when a car is right behind another one, in order to avoid a contact. The drivers prefer to apply the brakes just a little and keep the engine at full speed, rather than not touching the brakes and having to release the throttle.
6: The number of pistons in the front calipers for Short Tracks. On these tracks, the braking system is used for both braking and for helping the car to turn within a limited space, which explains the use of 6 pistons.
8: The number of NASCAR Cup Series won by Brembo brakes with six different drivers.
9: The millimeters of wear on the pad registered this year in Martinsville. In Watkins Glen, 11 millimeters were consumed. These figures may be different on other similar tracks depending on the friction material used and the pilot’s driving style.
22: The thickness in millimeters of the disc ventilation channels used in Watkins Glen, the most challenging circuit in the championship for braking systems since it is 3.35 miles long and has 11 turns spaced around it. Besides being the hardest, it’s also the racing circuit in the USA where Brembo has been winning for the longest time. In fact it was here that it collected its first Formula 1 successes in the seventies.
25: Years since the debut in NASCAR Cup Series of a car equipped with Brembo brakes. The first was with P.J. Jones driving a Melling Racing’s Ford at Watkins Glen. He crossed the finish line 8th, leaving behind 30 cars.
72: The maximum number of ventilation channels on each disc. Not much compared to the 1,400 holes on the discs used in Formula 1 or the 430 holes on the discs that equip the prototypes in the LMP1 class.
NASCAR’s drivers have to endure is definitively longer.
308: The diameter in millimeters of the front discs that are usually used for Intermediate Tracks. This value has been scientifically calculated to achieve the best performances possible with these cars on these tracks, minimizing the weight and maximizing the efficiency at the same time. Using larger (or smaller) discs would not provide the same combination of advantages as the 308 mm ones.
635:The degrees in Fahrenheit at which point the Brembo HTC 64T brake fluid boils, a figure that is better than rival products. This ensures greater resistance to Vapor Lock and efficient braking under any conditions.
Now that you’ve got all the numbers, you are all set for an exciting game of Bingo! Playing responsibly and with moderation is a pleasant, positive experience, but going to a NASCAR race is even more fun.
