Autospecialty Brake Shoe Line

The PowerStop Autospecialty brake shoe line focuses on OEM-standard fit and material consistency for drum brake service. For rear drum brake applications such as the Porsche 924 and Volkswagen Beetle, the B315 combines a semi-metallic compound with precision shaping to support reliable contact inside the drum and stable parking brake operation.

This part cross-references Raybestos Brakes 315PG and Wagner Brake Z315 for the same application.

Detailed Description

PowerStop B315 is a rear drum brake shoe set engineered for 1979-1982 Porsche 924 and 1967-1979 Volkswagen Beetle models. The bonded lining and semi-metallic friction formula are post cured to help deliver stronger initial braking response and reduce the time needed for break-in. Precision cam grinding helps the shoe sit correctly in the drum, while chamfered edges are used to limit brake noise and chatter. The steel backing is coated to resist rust, and the friction material is asbestos-free and copper-free.

What It Helps Address

• Rear brake noise or chatter from worn drum shoes
• Reduced parking brake performance on drum brake systems
• Uneven shoe-to-drum contact from aged or out-of-spec shoes
• Brake fade or inconsistent response from worn friction material
• Rust-related deterioration of the shoe backing plate

Installation Notes and Tips

Inspect the drum, wheel cylinder, return springs, and hardware condition before installation. Clean the backing plate contact points and verify drum diameter and shoe fitment before reassembly. Because mounting hardware is not included, reuse only serviceable components or replace worn brake hardware as needed. After installation, follow a proper brake-in procedure to seat the lining evenly.

Quality Assurance

PowerStop manufactures this brake shoe to strict OEM-style standards for fit, finish, and material consistency. The B315 uses new steel, rust-resistant coating, and copper-free, asbestos-free friction material to support dependable service in rear drum brake applications.
