Product Details

ATE Disc Brake Fixed Caliper 230099 is engineered for brake hydraulic service on Porsche 911 models from 1975-1979 and 1980-1983 in the front left position. The fixed caliper design supports stable pad clamping and predictable braking response, making it a practical replacement when servicing the front brake system on a Porsche 911. ATE subjects its calipers to extensive endurance testing and simulation before release, with a focus on material selection and manufacturing consistency. This part number 230099 is also referenced in aftermarket and OE-style cataloging for the same application.

The ATE Disc Brake Fixed Caliper product line is centered on brake hydraulics and caliper engineering, with a strong emphasis on aluminum and nodular cast iron fixed and floating caliper designs. For Porsche 911 owners and repair shops, that means a brake caliper built around tested construction and application-specific fitment rather than a universal replacement.

This part cross-references 91135142501 and 91135142502 for the same application.

What It Helps Fix

• Front left brake caliper leakage or hydraulic failure
• Uneven braking caused by a sticking or worn caliper
• Poor pad clamping from a damaged fixed caliper body
• Brake pull during front brake service on a Porsche 911
• Restoration or maintenance needs on 1975-1979 and 1980-1983 Porsche 911 front brakes

Installation Notes and Tips

Verify front left position, caliper type, and vehicle year before installation. This caliper does not include pads, so inspect pad condition, rotor wear, and brake hoses during service. After installation, bleed the hydraulic system and confirm proper pedal feel and brake balance before returning the vehicle to service.
