Good To Know

Q: How many magnets come in this kit? A: The kit includes two magnets, enough to service both brake assemblies on a single axle. Confirm your axle rating and brake size before ordering.

Q: Do I need to replace magnets in pairs? A: Replacing both magnets on an axle keeps braking force even from side to side. Pair them with fresh springs and shoes for the best result.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
