Rear Brake Drums | 4WD (1984-85 4Runner)

Rear Brake Drums | 4WD

For 1984–1985 Toyota 4Runner 4WD rear drum brake applications

Overview

The DFC OE Replacement Rear Brake Drum is a True Balanced direct-fit replacement for the factory rear drum brake system used on 1984–1985 1st Gen Toyota 4Runner 4WD models. It uses a 254.2 mm nominal braking diameter, a 6-hole 139.7 mm bolt circle, and application-specific Toyota 4WD dimensions.

The drum is precision machined and mill balanced to support smooth braking and reduce vibration or pedal pulsation. A black high-temperature coating protects exposed surfaces from corrosion.
