1. Air in the brake lines: Air in the brake lines can cause the brakes to feel spongy and unresponsive. To fix this issue, you will need to bleed the brakes to remove the air.
2. Low brake fluid: Low brake fluid can also cause spongy brakes. Check the brake fluid reservoir and add more fluid if necessary.
3. Worn brake pads or rotors: Worn brake pads or rotors can cause the brakes to feel spongy. Inspect the brake pads and rotors and replace them if necessary.
4. Faulty master cylinder or brake booster: A faulty master cylinder or brake booster can also cause spongy brakes. Have these components inspected by a qualified mechanic and replaced if necessary.
5. Damaged or leaking brake lines: Damaged or leaking brake lines can cause the brakes to feel spongy. Inspect the brake lines for any damage and replace them if necessary.
If you are not comfortable performing any of these repairs yourself, you should take your Land Rover to a qualified mechanic for diagnosis and repair.
