DFC True Balanced 1-Ton Rear Brake Drum

For 1979–1992 Toyota Pickup 1-Ton / Cab & Chassis SRW Applications

Overview

The Dynamic Friction Company (DFC) True Balanced Rear Brake Drum is a direct-fit replacement for specific heavy-duty Toyota Pickup rear brake applications. Within the 1979–1992 range, this drum is primarily cataloged for 1-ton, Cab & Chassis, camper, and single-rear-wheel (SRW) configurations rather than standard 1/2-ton or 3/4-ton pickups.

DFC machines and balances its True Balanced drums to help maintain smooth braking operation and reduce vibration or pedal pulsation. The uses a 254 mm nominal braking diameter, 5-lug 114.3 mm bolt circle, 67 mm center bore, and a deeper 78 mm overall height suited to these heavy-duty brake applications.

This is not the standard 1979–1983 2WD drum or the 6-lug 4WD drum. Verify the truck's load rating and rear brake configuration before ordering.
