Preparation:
1. Park the truck on a level surface and apply the parking brake.
2. Ensure that the truck is in neutral gear.
3. Have the necessary tools and safety gear ready, including a lug wrench, a brake spoon or adjuster, and gloves.
Adjusting the Rear Brakes:
1. Locate the brake drums on the rear wheels of the truck. They are usually behind the wheels and can be identified by their cylindrical shape.
2. Remove the hubcaps or wheel covers if necessary to access the brake drums.
3. Loosen the lug nuts on the rear wheels but do not remove them completely.
4. Jack up the rear of the truck using a jack and place jack stands under the frame for safety.
5. Remove the lug nuts and take off the rear wheel.
6. Inspect the brake pads inside the brake drum. If they are worn out or below the recommended thickness, they need to be replaced.
7. If adjusting the brake shoes is necessary, locate the brake adjuster, which is usually a small wheel or star-shaped adjuster visible through a hole in the backing plate.
8. Insert the brake spoon or adjuster into the hole and turn it clockwise to tighten the brake shoes. This will move the brake shoes closer to the brake drum, increasing the braking power.
9. Continue adjusting the brake shoes until you feel a slight drag when spinning the wheel by hand.
10. Repeat the adjustment for the other brake shoe on the same wheel.
11. Reinstall the wheel, tighten the lug nuts, and lower the truck.
Adjusting the Front Brakes:
1. Remove the front wheel in a similar manner as described for the rear wheels.
2. Locate the caliper that holds the brake pads in place. It is usually attached to the wheel hub or suspension component.
3. Use a wrench to loosen the bolts that hold the caliper in place. Do not remove the bolts completely.
4. Slide the caliper off the brake rotor and inspect the brake pads. If they are worn out, replace them with new ones.
5. If adjusting the brake pads is necessary, locate the caliper piston, which is a cylindrical component that moves the brake pads against the rotor.
6. Use a C-clamp or brake piston tool to carefully push the caliper piston back into its housing, creating more clearance for the brake pads.
7. Slide the caliper back into position over the brake rotor and secure it with the bolts you loosened earlier.
8. Reinstall the wheel, tighten the lug nuts, and lower the vehicle.
Testing the Brakes:
1. Start the truck and allow it to idle.
2. Press the brake pedal several times to check the brake response. The pedal should feel firm and provide adequate braking power.
3. If you notice any issues or irregularities, recheck the brake adjustment and ensure that everything is properly aligned.
Note:
1. Always follow the brake adjustment procedures provided in the truck's service manual specific to your Mitsubishi Fuso model.
2. If you are not comfortable performing brake adjustments yourself, it is recommended to seek assistance from a trained mechanic or take the vehicle to a reputable auto repair shop.
3. Properly maintained brakes are crucial for safety, so it is important to inspect and adjust them regularly.
