• Prevents brake fluid leaks that reduce braking efficiency
• Ensures proper bleeding to remove air from the brake system
• Prevents corrosion-related failures in old or damaged screws
• Maintains consistent hydraulic pressure for safe braking

Brake caliper bleed screws are essential for maintaining a responsive braking system by allowing the removal of air from brake lines. Over time, they can corrode, strip, or seize, leading to brake fluid leaks or ineffective bleeding. Replacing worn-out screws ensures a proper seal, preventing air entry and maintaining consistent hydraulic pressure. For Defender, Discovery 1, and Range Rover Classic models, timely replacement helps avoid braking inefficiencies and potential safety hazards.
