Rear brakes are traditional twin-shoe type.

Contents

Overview

The same rear brake drum was used 1967-1994. It is an 8" diameter cast iron drum, that fits 1-3/8 wide brake shoes.

Starting from Oct 1989, Sunny Trucks started using a different brake shoe -- while still using the same drum as early 1200s. These late model 1200s use a self-adjusting rear brake system. Aside from the drum, all the parts differ from earlier rear brakes.
