Wagner Brake BD180390E Rear Rotor

Wagner Brake BD180390E is a rear disc brake rotor built for vehicles that use a 315mm vented rotor and a 5-lug wheel pattern. It combines cast iron construction with a rust-resistant coating for dependable braking performance and easier installation.

Key Features

  • Cast iron, full-cast rotor construction
  • Vented design for rear brake applications
  • Rust-resistant coating on the non-braking surface
  • Smooth, directional brake surface
  • 315.0 mm outside diameter and 23.0 mm nominal thickness
  • 5 stud / lug hole pattern

Detailed Description

This Wagner Brake disc brake rotor is engineered for rear brake service where a vented, directional rotor is specified. The cast iron build provides a stable braking surface, while the corrosion-resistant coating helps protect exposed areas from rust during daily driving and seasonal exposure. For buyers searching for a rear brake rotor for Chevrolet Impala, Cadillac XTS, Buick Regal, or Buick LaCrosse applications, BD180390E matches the listed fitment requirements and dimensions.

It cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

  • Brake pulsation caused by worn or uneven rotor surfaces
  • Reduced braking consistency from heat-worn rear rotors
  • Rust buildup on exposed rotor surfaces
  • Noise or vibration linked to rotor wear
  • Incorrect rotor sizing on 315mm rear brake setups

Installation Notes and Tips

Compatible With rear positions only on the listed applications. Verify 315mm rotor diameter, vented rotor configuration, and 5-stud wheel fitment before installation. The rotor uses a directional brake surface, so orientation matters during service. Pairing Wagner rotors with Wagner brake pads supports matched brake system service.

Quality Assurance

Wagner Brake premium rotors are engineered with a focus on performance, corrosion resistance, and straightforward installation. BD180390E is built to the published specifications for the listed vehicle applications.

This part fits 37 vehicles
Always verify fitment with your vehicle's VIN if unsure. Submodel & trim restrictions may apply.
