This is a set of Brass Scale Brake Disc Set for BRX70/80/90/AR44Front Axle.

The set includes a pair of aluminum knuckles with detachable arm levers. You have the option to run behind the axle steering. It is a direct replacement of the stock AR44 knuckle. The knuckles will fit Boom Racing AR44 axle and plastic stock AR44 axle, as well as BRX70, BRX80 and BRX90 axles.

A brass adapter (black anodized) attaches to the knuckle and the brass caliper attaches to the brass adapter. On the front, it can take up to two calipers on each adapter (for weight adjustments).

The stainless steel brake disc is machined together with a 12mm standard hex. The hex uses a drive pin and has two set screws to lock down the drive shaft securely.

This brake system is not designed for 1.55" wheels. Will fit Boom Racing 1.55" 16-Hole Steelies if used in deep-dish setup.
