Important Safety Note: Always engage the parking brake before working under the vehicle to prevent it from rolling. Use jack stands and follow all safety precautions for working on a vehicle.
The Process Generally Involves These Steps (but consult your manual):
1. Locate the Emergency Brake Cables: Trace the cables from the emergency brake handle inside the cab, under the vehicle towards the rear wheels. You'll likely find them running along the frame rails.
2. Access the Rear Calipers: You'll need to access the rear brake calipers. This often involves removing a wheel.
3. Locate the Adjustment Mechanism: Each rear caliper likely has a small ratchet-style adjuster for the emergency brake. This is often a small, threaded wheel or a similar mechanism. It may be partially or fully covered by a dust shield or other components. You may need to remove a small access panel or carefully manipulate the dust shield to reach it.
4. Adjust the Cable(s): Using a small wrench or screwdriver (depending on the design), carefully turn the adjuster to tighten the emergency brake cable. You should be able to feel resistance as you turn it. Do this slowly and in small increments.
5. Test the Brake: After making adjustments at each caliper, test the emergency brake to see how many clicks it takes to fully engage. It should hold the vehicle securely on a slight incline. If the brakes grab too soon or are too tight, back off the adjuster.
6. Repeat if Necessary: Continue adjusting, testing, and readjusting at each rear caliper until you achieve the desired level of engagement.
Important Considerations:
* Wear: If your emergency brake is very loose or doesn't engage, it may be due to worn-out brake pads or components in the caliper, and not just cable adjustment. The adjuster may be at its maximum and still not engage properly.
* Professional Help: If you're uncomfortable working on your brakes or can't locate the adjustment mechanism, it's best to take your vehicle to a qualified mechanic. Improper brake adjustments can compromise your safety.
* Manual is Crucial: The precise location and type of adjustment mechanism will vary depending on the exact model and configuration of your 1999 E-350. Your owner's manual will provide the most accurate and safe instructions. Searching online for a "1999 Ford E-350 brake system diagram" might also help you visualize the components involved.
Remember, brake systems are crucial for safety. If you're unsure about any step, seek professional assistance.
