What It Helps Address

• Brake drag or uneven braking from a worn front left caliper
• Hydraulic leakage at the caliper body or piston area
• Reduced braking response caused by caliper wear or corrosion
• Restoration work on a Porsche 911 front brake system
• Replacement of a damaged ATE Disc Brake Fixed Caliper 230129 unit

Installation Notes

Verify front left position, caliper type, and model-year fitment before installation. This caliper does not include pads, so confirm pad selection separately.
