Where does the emergency brake cable go in a rear drum?
In a rear drum situation, the emergency brake cable runs directly to the brake shoes, bypassing the hydraulic brake system. In this simple, mechanical bypass, the emergency brake system requires no extra parts to control the brakes [source: Owen ].
Where is the emergency brake cable on a hot rod?

How do I reinstall the emergency brake cable?
On reinstallation, it’s a good idea to feed the cable with the ball end through the stub frame first, get the ball hooked through the spreader, and then feed the other end through the drum. After that you can install the outside retaining clip, then hook the cable up to the lever that gets reinstalled on the shoe.
What causes rear drum brakes to engage too soon?
If the parking brake system is not de-adjusted properly before the brake shoes are adjusted it will cause the rear brakes to engage too soon. This is especially true of vehicles equipped with duo-servo rear drum brakes (see Figure 61.1).
