Technical Description and Features

The L4792 caliper features a lightweight aluminum casting that helps reduce unsprung weight while maintaining structural integrity. Its single 38.10 mm phenolic piston offers improved heat resistance compared to traditional metal pistons, reducing the risk of brake fluid boiling under heavy use. The floating caliper design allows for smooth, even pad wear and reliable braking response. Included caliper slides and mounting bracket facilitate proper alignment and installation. The gray finish provides corrosion protection and a clean appearance.

Compatible Vehicles and Common Applications

• Replacement for front disc brake calipers on Ford Thunderbird models
• Compatible with Jaguar S-Type front brake systems
• Suitable for Lincoln LS front brake hydraulic repairs
• Ideal for addressing caliper leaks, sticking pistons, or uneven brake pad wear
• Used to restore proper brake function and pedal feel

Installation Notes and Tips

Ensure the brake system is properly bled after installation to remove air and maintain braking efficiency. Verify that the mounting bracket is securely fastened and that caliper slides move freely to prevent uneven pad wear. Use the correct bleeder screw size (M10 x 1.0) for brake fluid evacuation. This caliper does not include mounting hardware, so retain original components or source separately if needed.
