Technical Description and Features

The L4970 caliper features a floating design with a single phenolic piston measuring 41.91 mm in diameter. The use of phenolic material for the piston helps reduce heat transfer to the brake fluid, minimizing the risk of brake fade under normal driving conditions. The aluminum caliper casting offers a balance of strength and corrosion resistance, contributing to the longevity of the part. Included caliper slides and mounting bracket facilitate proper installation and alignment on the rear brake assembly. The gray finish provides a neutral appearance suitable for most brake setups.

Common Applications and Problem Solving

• Replacement for worn or seized rear calipers on Chrysler 300 and Dodge Charger
• Restores proper brake pad alignment and caliper movement on Dodge Challenger
• Addresses brake fluid leaks caused by damaged phenolic pistons
• Resolves uneven brake pad wear due to faulty caliper slides
• Improves rear braking performance on Dodge Magnum with original equipment specifications

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 1.5) when performing brake bleeding procedures. This caliper does not include mounting hardware, so reuse existing hardware or acquire appropriate replacements as needed.
