2. Inspect and Replace Brake Components

Inspect Brake Shoes and Rotors:

- Check the rotors for grooves or damage; replace if necessary.
Replace Brake Shoes (if needed):
- Remove the retaining springs and adjuster from the old shoes.
- Install new brake shoes in reverse order of removal.
- Ensure all components are seated properly.

3. Adjust Emergency Brake Cable

Locate the emergency brake cable under the vehicle.
Adjust the tension using the adjustment nut until the cable is taut but not overly tight.
Test the engagement by pulling the emergency brake lever; it should hold firmly.

4. Reassemble and Test

Reattach the wheels and torque them to the manufacturer's specifications.
Reconnect the battery.
Test the emergency brake by engaging it on a flat surface to ensure it holds the vehicle.
