What Are Backing Plates? A Professional Classification Guide
If you have ever asked "what are backing plates," you already know they are essential to brake safety.
But not all backing plates are the same. Understanding the different types helps you choose the right
component for your vehicle, fleet, or aftermarket business.
At Bainuo Brake, we manufacture high-quality backing plates for drum brake systems worldwide. Below,
we classify backing plates by design, application, and material — so you can make an informed decision.
1. By Brake System Type
Drum Brake Backing Plates
– These are the large, circular metal plates fixed to the axle hub. They hold all
internal components: brake shoes, wheel cylinder, springs, and adjusters. When people ask "what are
backing plates," this is the most common answer.

Disc Brake Backing Plates
– These are the steel plates bonded to disc brake pads. They provide rigidity
and reduce noise. Though smaller, they are equally critical for performance.


2. By Vehicle Application
Passenger Vehicle Backing Plates – Lighter, precision-stamped for cars and SUVs.

Commercial Truck Backing Plates – Heavy-duty, thicker steel for high torque and heat.

Off-Road & Agricultural Backing Plates – Corrosion-resistant coatings to withstand mud, water, and debris.
3. By Material & Coating
Standard Steel Backing Plates – Economical, suitable for normal conditions.
Zinc-Plated Backing Plates – Rust-resistant, ideal for wet environments.
High-Strength Alloy Backing Plates – For extreme loads and long service life.
