The Cradock brake discs are manufactured from a space age composite material which is resistant to incredibly high temperatures, which in terms of RC is only going to be a good thing to enable fade-free braking in those long A-Mains. The brakes themselves offer tremendous ammounts of braking friction while maintaining a linear braking curve with plenty of progression. The brakes are available in two designs, these are the 'Anti-Lock' type which is a staggered disc which is designed to offer further progression to the braking feel, in turn maximizing traction on low grip dusty/dirty surfaces. The brake discs are sold in pairs of two discs, which on the majority of 1/8 buggys and truggys on the market is the correct ammount in order to directly replace both discs.
Please Note: For use on the Xray 808 you will need to remove a slight ammount of material from where the disks passes over the pin in the end of the driveshaft, this is because on the 808 the pin is slightly over sized. If your not confident enough to do this yourself, just ask and we will do it for you.
