Nascar: Why is it necessary to use different braking systems at tracks such as Bristol vs Daytona?

The drivers are on the brakes every corner at Bristol and Martinsville. This is why they put heavier duty brakes on the short track cars

They won't hit their brakes at all under normal circumstances on the super speedway tracks, so they put very light brakes on those cars.

What makes the brakes heavier duty is thicker, larger brake rotors and thicker, larger brake pads.

When you add rotating weight to each wheel (larger rotors) then it takes more energy (horsepower) to turn.

This is why they use different brakes on different tracks, they balance out the weight gain/reduction with having a safer, more controllable car.

Brakes are seldom used at Daytona being a RP Track they are full throttle around the whole place. At Short Tracks like Bristol & Martinsville & Road Courses drivers are using the brakes all the time to slow the car down to get into the turns.

Brakes are used way more at Bristol than Daytona

the same goes for the cookie cutter tracks

Because you don't need to brake at Daytona, unless you try to avoid a wreck, so a better brake system is not neccesary, it can affect the weight of your car and affect overall performance.

Daytona, it has extra history with the and the Firecracker/Pepsi/Coke 0 4 hundred and it is the international center of Racing. Plus there's a lot to do with Volusia Mall around the line and all of the attractions like the coastline being some miles away. Talladega is actual interior the middle of nowhere.
