Wagner Brake Z151R Drum Brake Shoe - Front or Rear

Wagner Z151R Rear Drum Brake Shoe

The Wagner Z151R is a rear drum brake shoe built for vehicles using 10-inch x 1-3/4-inch rear drum brakes. It uses OE-matched friction material and precision-ground surfaces to promote consistent drum contact and predictable braking response.

Compatible with select Ford Mustang, Mercury Cougar, and other rear drum brake applications, this Wagner brake shoe is built around the friction and fit details that matter for service work on classic and late-model platforms.

Detailed Description

Wagner Brake Z151R is a rear drum brake shoe engineered for vehicles that use a 10-inch by 1-3/4-inch brake setup. The organic friction material is matched to OE-style performance expectations, while the precision-ground construction helps maximize contact between the shoe and drum for more even braking action. This makes the Z151R a practical service part for restoring rear brake function on applications such as Ford Mustang, Mercury Cougar, and Ford Thunderbird models listed in the fitment data.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. The Wagner Z151R also cross-references 151SG and R151.

What It Helps Fix

• Rear brake noise caused by worn drum shoe friction material
• Reduced braking performance from thin or glazed shoes
• Uneven drum contact that can affect pedal feel
• Service issues on 10-inch x 1-3/4-inch rear drum brake systems
• Brake maintenance needs on classic Ford Mustang and Mercury Cougar rear drum setups

Installation Notes

Verify drum diameter, shoe width, and rear position before installation. This Z151R brake shoe is for rear applications with 10-inch x 1-3/4-inch brakes, and mounting hardware is not included. Inspect the brake drum, wheel cylinders, return springs, and adjuster components during service, and replace any worn parts before final assembly. Confirm fitment against the vehicle’s brake configuration, especially on Ford Mustang and Mercury Cougar applications.

Quality Assurance

Wagner Brake uses OE-matched friction materials and precision-ground surfaces to support consistent brake performance and drum contact. The Z151R is built to the FMSI S151R specification for the listed rear drum brake applications.
