The brake master cylinder plays an integral role in your Land Rover brake system, so it is important to ensure that your part is in proper working order. Brake fluid absorbs water and water can loosen tiny particles along your brake lines, causing damage to your brake master cylinder. The seals on the brake master cylinder are often the first areas to fail. If your brake system is not working properly and you suspect a brake master cylinder issue, replace it immediately.
