Detailed Description

Part number 97P17277A is a front left disc brake caliper for a wide range of early-1990s Buick, Cadillac, Chevrolet, Oldsmobile, and Pontiac vehicles. The TechShield 360 line identifies this caliper as part of Nugeon’s corrosion-focused product family, and the E-coat finish supports long-term surface protection in demanding brake environments. The housing cast numbers 515, 201, and 831 are listed for identification purposes.

With a cast iron body, steel piston, and included dust boots, this caliper is built around the core hydraulic and sealing components needed for brake service. The banjo bolt inlet, M10-1.5 bleeder thread, and included bleeder screw help match the original brake plumbing used on the confirmed applications. Part number 97P17277A is a direct fit for the listed front left vehicles, including Buick Park Avenue and Cadillac DeVille applications.

What It Helps Address

• Leaking or sticking brake caliper housing
• Uneven brake pad contact from worn hydraulic components
• Corrosion on the caliper body or finish
• Brake service needs involving the bleeder screw or inlet connection
• Brake drag caused by internal caliper wear

Installation Notes

Verify the vehicle’s front left fitment, brake configuration notes, and inlet connection before installation. This caliper uses a banjo bolt inlet and M10-1.5 thread sizing, so the brake line connection must match the original setup. Confirm pad number D505 and the listed application details before completing service on the Buick, Cadillac, Chevrolet, Oldsmobile, or Pontiac vehicle.

Quality Assurance

Nugeon TechShield 360 calipers are built with corrosion-resistant finishing and OE-style construction details for service replacement use. The caliper manufacturer is listed as Akebono, and the part includes the core service features needed for brake hydraulic replacement.
