During deceleration, expanding brake shoes press against the drum interior to create friction and convert motion into heat. Designed with a 10-hole bolt configuration and a 16.5 x 8.6 in. size profile, this unit fits wheel ends that require these dimensions. Proper installation helps maintain steady contact between the shoes and the drum during operation. Technicians position the drum over the studs and secure it before adjusting brake components. The Webb 66854B supports consistent braking response in compatible hydraulic setups.
