1. Safety Precautions:
- Engage the parking brake and chock the wheels to ensure the mower won't move during the process.
- Disconnect the spark plug wire to prevent the engine from accidentally starting.
2. Raise the Mower Deck:
- Engage the "Raise the Deck" lever until it's lifted as high as possible, providing access to the brake mechanism.
3. Remove the Brake Adjustment Cap:
- Locate the brake adjustment cap underneath the mower deck, near the brake lever.
- Remove the cap using a screwdriver or a spanner.
4. Adjust the Brake Lever:
- Push down the brake lever by hand until it's released.
- Locate the brake shoe adjuster at the end of the brake lever.
- Turn the adjuster clockwise until it almost entirely blocks the brake rotor, preventing its movement.
5. Remove the Wheel Assembly:
- Loosen the lug nuts on one of the rear wheels that need new brake pads.
- Use a jack (or similar tool) to raise the mower deck on that side sufficiently to remove the wheel.
- Remove the lug nuts and take off the wheel.
6. Remove the Brake Caliper:
- On some models, you may find two brake calipers — one for the parking brake and another for the foot brake.
- Locate the brake caliper related to the wheel you're working on.
- There are typically two bolts holding the brake caliper in place. Use a wrench to remove these bolts.
- Once the bolts are removed, gently lift the caliper off the rotor.
7. Remove the Old Brake Pads:
- Inside the caliper, you'll find two brake pads.
- Inspect the old brake pads for wear and replace them if they are worn or damaged.
8. Install New Brake Pads:
- Slide the new brake pads into the caliper.
- Make sure they are properly seated and secured.
9. Reattach the Brake Caliper:
- Place the brake caliper back onto the brake rotor.
- Secure it by reinstalling the two bolts that you removed earlier.
10. Reinstall the Wheel:
- Place the wheel back onto the axle and secure it with the lug nuts. Ensure that the lug nuts are tightened securely.
11. Lower the Mower Deck:
- Disengage the "Raise the Deck" lever to lower the mower deck.
12. Adjust the Brake Lever (Optional):
- If the brake pedal feels spongy, you may need to adjust the brake lever.
- Refer to your John Deere GX75 mower's manual for instructions on brake adjustment.
13. Reconnect the Spark Plug Wire:
- Reconnect the spark plug wire to its original position.
14. Test the Brakes:
- Check if the foot brake is working properly by pressing it down firmly and ensuring the mower stops.
Remember, these steps are general guidelines and may vary slightly based on your specific model. Always refer to the John Deere GX75 Mower's operator manual for accurate instructions.
