Understanding the E-Break System
The E-brake system is designed to provide an additional layer of safety by allowing the driver to apply the brakes in the event of an emergency. The system typically consists of a lever or pedal that is connected to a cable or linkage that activates the brake shoes. The brake shoes are designed to apply pressure to the drum, causing the vehicle to slow down or come to a stop.
The E-brake system is typically adjusted by adjusting the length of the cable or linkage. This is done by turning the adjusting nut or screw that is located at the end of the cable or linkage. Turning the nut or screw in a clockwise direction will tighten the cable or linkage, while turning it in a counterclockwise direction will loosen it.
Tools and Materials Needed
Before attempting to adjust the E-brake, it is essential to have the following tools and materials:
- A socket wrench or ratchet and socket set
- A torque wrench
- A brake adjustment tool (if available)
- A pair of gloves
- A safety glasses
It is also recommended to have a repair manual or a diagram of the E-brake system to help guide the adjustment process.
Step-by-Step Instructions
The following are the step-by-step instructions for adjusting the E-brake on drum brakes:
Step 1: Locate the E-Break Adjusting Nut or Screw

Step 5: Check the Brake Pedal Height Again
After tightening the nut or screw, check the brake pedal height again. The brake pedal should still be at the recommended height.
Step 6: Test the E-Break
Test the E-brake by pulling the brake lever or pedal. The vehicle should come to a stop or slow down significantly. If the E-brake does not function properly, it may be necessary to adjust the brake shoes or other components of the drum brake system.
