PowerStop B197 Drum Brake Shoe - Front or Rear

Overview

PowerStop Autospecialty brake shoes are built for classic drum brake applications that call for precise drum contact and consistent pedal feel. This B197 brake shoe uses a semi-metallic friction formula, post-cured construction, and a riveted attachment style for a direct replacement on supported Buick and Pontiac applications.

Compatible With Buick and Pontiac drum brake setups, this B197 part number is engineered for fitment across front and rear positions where the listed 11x2-1/4 inch and 12x2-1/4 inch brake configurations apply.

Key Features

• Semi-metallic friction material for strong braking response.
• Post-cured construction for shorter break-in time.
• Precision cam-ground for drum fitment.
• Chamfered edges to reduce noise and chatter.
• New steel construction with rust-resistant coating.
• Asbestos-free and copper-free friction material.
• Riveted friction material attachment.

Detailed Description

The PowerStop Autospecialty brake shoe line focuses on OE-style precision for drum brake service. The B197 is made with a semi-metallic compound that is post cured to improve initial braking performance, while cam grinding helps the shoe seat properly against the drum surface. Chamfered edges further support quieter operation during stop-and-go use.

This part number, B197, cross-references Centric Parts 111.01970 and Raybestos Brakes 197PG for the same application. It is a practical choice for restoring braking performance on Buick Roadmaster, Buick Century, and Pontiac Catalina applications where the original drum brake dimensions match the listed fitment.

What It Helps Address

• Reduced braking response from worn drum brake shoes.
• Noise and chatter caused by uneven shoe contact.
• Longer break-in time after brake service.
• Rust-related wear on exposed shoe components.
• Poor drum fitment from aged or out-of-spec shoes.
