Product Details
Wagner Brake Z315 is a drum brake shoe designed around OE-matched friction characteristics and accurate surface finishing. The organic friction compound supports predictable pedal feel, while the precision-ground material helps the shoe seat properly against the drum. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. It fits 1977-1982 Porsche 924, rear, except Sport or Special Equipment Package; with 9-1/16 in. x 1-37/64 in. brakes, and fits 1968-1979 Volkswagen Beetle, rear, with 9-1/16 in. x 1-37/64 in. brakes. The Wagner Z315 is a direct-fit choice for owners servicing rear drum brake systems on classic Porsche 924 and Volkswagen Beetle models.
What It Helps Address
- Reduced braking response from worn rear drum shoes
- Uneven shoe-to-drum contact
- Brake noise caused by aged friction surfaces
- Loss of consistent rear brake performance
- Service needs on 9-1/16 in. x 1-37/64 in. rear drum brake setups
Installation Notes and Tips
Verify drum diameter, shoe width, and FMSI S315 match the vehicle before installation. Inspect the brake drum for scoring, taper, or out-of-round wear, and replace or machine the drum as needed to restore proper contact. Because mounting hardware is not included, reuse or replace related brake hardware separately if required by the service procedure. After installation, adjust the rear drum brakes and perform a careful road test to confirm proper pedal feel and balance.
