The shoe width measures 36.9 mm, and the listed drum diameter is 230.124 mm, matching the specified 9.06 x 1.45 inch brake setup. This part number, PMB945B, also carries FMSI reference S945-1635 for identification during brake service.

What It Is Used For

• Replacing worn rear drum brake shoes.
• Restoring braking response when lining material is thin or uneven.
• Addressing brake noise caused by worn shoe friction surfaces.
• Correcting reduced parking brake effectiveness in drum brake systems.
• Servicing rear brake assemblies that match the specified drum size.

Installation Notes and Tips

Verify the brake drum diameter, shoe width, and FMSI number before installation. Confirm rear application and compare the existing hardware layout, including parking brake lever requirements, against the product listing. Use the vehicle's brake specification rather than model name alone to confirm fitment for Toyota Corolla, Toyota Prius C, Toyota Yaris R, or Scion xD applications.

Quality Assurance
