What are Brake Pads Backing Plates?

Drum braking systems are used as the rear brakes in many modern cars as well as the front brakes in larger trucks and older cars. The backing plate forms a base or foundation for a drum brake, allowing it to slow your car down effectively.

Brake backing plates are usually made of durable steel. Mounted to the backing plate is the wheel cylinder, which has the brake shoe attached to it. Without a backing plate, the rest of the braking system would have nothing to grip onto.

Purpose of the Brake Pads Backing Plates

Made of cast iron, commercial backing plates are what the wheel cylinder mounts onto. The brake shoes are then firmly attached to the backing plate unit, providing them with the required grip to stop a vehicle, using friction as a force.

Backing plates can also refer to the comma-shaped component within disc brake systems. In this instance, the brake shoes have a backing plate consisting of a friction surface which is riveted or glued into place.

The Functions of Brake Backing Plates

Mounting

It has mounting points that securely hold the brake shoes or pads and allow the friction material to apply even pressure to the drum or disc.

Alignment

The backing plate precisely positions the friction material onto the drum or disc for optimum braking performance.

Shielding

The backplate protects your hubs, bearings, and calipers from debris and dirt created during braking, extending their life.

Noise Reduction

It isolates vibration between disc and caliper, reducing squeal and grinding noise during braking.

Dust Resistant

The back plate traps most brake dust particles, preventing them from escaping into the wheel wells, and keeping the wheels and underbody clean.

The Type of Steel Backing Plate

Stamped Hole Backing Plates

Brake pad backing plates with holes are also called stamped hole backing plates or punched hole steel plates. They are widely used backing plates for car brake pads and medium, heavy duty truck trailer brake pads. Now, more than 95% of passenger vehicle brake pads are made of stamped hole back plate.

Wire Mesh Backing Plate

Generally, Wire mesh backing plates are also called steel mesh backing plates or weld mesh steel plates. They are widely used backing plates for medium, heavy duty brake pads. Wire mesh steel plate is constituted by steel wire mesh welded to the backing plate to help provide mechanical retention for friction material.

Casting Iron Backing Plates

Cast iron backing plates for brake pads are also called casting back plates or cased plates. Brake pads cast backing plates is made of cast iron material by foundry progress. With the perfect design, the cast iron backing plate can provide excellent shear strength for the brake pad. So they are widely used in Commercial vehicle brake pads.

Handling Process of the Backing Plate

Stamping of the Backing Plate

Stamp the backing plate form high-grade steel into the exact design shape to fit vehicle caliper.

Surface Blasting

Roughen the surface of backing plate for increasing the adhesion to avoid material breaking away from the backing plate.

Applying the Adhesive to the Surface

Apply the adhesive to the backing plate and get ready to bond the friction materials.

Symptoms of Worn Brake Backing Plates

Grinding Noises

The backing plates can produce loud grinding noises when they are damaged. This is often caused by the abnormalities or warping which cause other parts to grind against the plate. This results in increased friction, which can cause wear to multiple parts.

Uneven Braking

Uneven braking occurs when one side of your car generates more brake pressure than the other. As a result, the car will often pull to one side when brakes are applied.

Brakes Loose or Rattling

A damaged backing plate can cause the brake shoe or wheel cylinder to become loose. This can result in audible shaking from the corresponding wheel.

Increased Stopping Distance

As well as causing rattling, a loose brake shoe will result in reduced stopping distance, which can affect the safety of your car.

Why Your Brake Pad Backing Plate Fell Off

What Causes a Brake Pad to Fall Out

1. Rust Jacking: One of the primary causes of brake pad separation is rust jacking. Over time, the backing plate can rust, leading to the expansion of rust and subsequent separation of the friction material from the pad. In a study focusing on brake pad failures, it was found that low-quality steel backing plates were the main culprits behind this issue.

2. Backing Plate Flex: Another factor contributing to brake pad separation is the flexing of the backing plate. Inferior backing plate thickness can cause flexing, leading to a separation of the friction material from the pad. This flexing motion puts stress on the bonding adhesive, making it more susceptible to failure.

3. Inferior Friction Material and Bonding Adhesive: The quality of the friction material and bonding adhesive used in the manufacturing process also plays a significant role in brake pad durability. Inferior materials can result in inadequate bonding strength, leading to the separation of the friction material from the backing plate.

Preventive Measures

1. Choose Premium Quality Brake Pads: When replacing your brake pads, it is advisable to opt for premium quality name brand pads. These pads often utilize higher-grade materials and superior construction techniques, reducing the likelihood of separation issues. Consider brands that have a reputation for providing reliable and durable brake pads.

2. Consider Galvanized Steel Backing Plates: To combat rust-related problems, you may want to explore brake pads that feature galvanized steel backing plates. These plates have enhanced corrosion resistance, minimizing the risk of rust jacking and subsequent separation.

3.Research Manufacturer Warranties: If you encounter brake pad separation issues, reach out to the manufacturer. Many reputable manufacturers offer warranties on their products, providing you with potential recourse in case of premature failure. Contacting the manufacturer can help you understand if your specific situation is covered by the warranty.

Common Problems of Brake Pads Backing Plates

Q: What is a back plate on a brake?

A: Backing Plates are also known as Brake Plates. Backing Plates act as a heat shield for non-metal parts like ball joints which can be damaged from heat caused by braking friction. Backing plates, often paired with topping plates, play a critical role in spreading load across the substrate to which hardware is bolted.

Q: How does the back plate work?

A: Commercial backing plates hold the entire brake system together. They come into action when a driver pushes down the brake pedal, which apples pressure on the hydraulic fluid found in the brake lines. As the hydraulic fluid enters the brake cylinder, its pistons are forced outwards. This then triggers the outside edge of the brake shoes to come into contact with the inner surface of the brake drum. The friction of this process will slow the vehicle down, before it eventually comes to a stop.

Q: Do disc brakes need a backing plate?

A: Yes. The backing plate is critical for reliable braking performance. Zhongwei engineers all backing plates, regardless of type, to meet critical dimensions. All disc plates are designed to follow the OE for form, fit and function. The steel is designed to last the life of the brake pad, reduce the chance of rust and operate with proper brake pad movement and quiet operation.

Q: When should the backing plate be replaced?

A: The best time to have brake backing plates replaced is when you start to notice symptoms, or when a mechanic point the problem out to you. The longer the damage to the plates is ignored, the worse it can become. Eventually, the backing plate may be unable to support the rest of the braking system and this can greatly affect your car’s safety.

Q: Why does my backing plate make a noise?

A: Backing plates can get weak and damaged over time. This can be general wear and tear, or incorrect or forceful fitting. A worn back plate can cause noise and even brake failure. If you can see tapered pads, this will be caused by the caliper. Either the caliper slides are sticking, the caliper has become distorted or there may be excessive caliper clearance.

Q: What are the different types of backing plates?

A: In a new installation or retrofit, the choice of backing-plate material is the first step. There are four main types of backing plate materials: plywood, aluminum, stainless steel, and G10 fiberglass board.

Q: How often should you change brake plates?

A: Generally, your car's brake pads should be replaced every 25,000 to 65,000 miles, while your rotors should be replaced between 30,000 and 70,000 miles. However, the exact figure can vary depending on your terrain, weather conditions, and driving style.

Q: How do you bend a backing plate?

A: You can bend it back by using your hands. Take off the wheel and you will see the backing plate right behind the brake rotor. Grab it by the edge and bend it back.

Q: Are backing plates necessary?

A: Without cast iron backing plates, all the hardware attached to the brake unit would have nothing to grip to. In addition, backing plates act as a shield for non-metal components which would otherwise be damaged by the heat that braking friction causes. Thanks to the design of the brake systems, any excessive heat build-up is dispersed, preventing any harm.

Q: Why does my brake backing plate squeak?

A: Sometimes, squealing can result from a lack of adequate lubrication around the pins that attach the brake pad to the caliper cavity or insufficient lubrication on the backing plates of the brake pads. Other times, a squeal can be caused by brake pads rubbing rust off a rotor. In either case, it’s a good idea to check the lubrication of your braking system.

Q: Does a bent backing plate cause brake grabbing?

A: Drum brake backing plates can also be bent. Improper service, like prying brake drums off, often bends the backing plate. When the plate is bent, the shoes are not supported and do not slide properly. Noise, lockup, grabbing brakes and front brake issues are often the symptoms. Bent backing plates can be identified with a dial indicator or run-out gauge.

Q: Can you drive without a brake backing plate?

A: Technically a brake backing plate is what the brake shoes are attached to on a DRUM brake system. The plate, along with the anchor pin, is what retains the brake shoes to the vehicle. So in this application it is not only necessary the system does not exist without it.

Q: Are brake backing plates necessary for mot?

A: Yep. Drum brake back plate definitely need to be solid. Disc brake back plates are just heat/dust Shields. Definitely advise that they are still fitted, but don't worry about that one on yours, for the mot.

Q: What holds the brake shoe against the backing plate?

A: Springs hold the brake shoes in place so they don't contact the drum when the brakes aren't active. When the driver pushes down on the brake pedal, this places pressure on the hydraulic fluid in the brake lines. At the top of the backing plate is a wheel cylinder containing two pistons, one at either end. The pressure from the brake fluid enters the wheel cylinder and forces the spring-loaded pistons to move outward from the wheel cylinder, pushing the brake shoes against the inside of the brake drum.

Q: What is located on the top of a backing plate?

A: A wheel cylinder containing two pistons at the top and bottom can be found at the top of the backing plate. As the hydraulic fluid enters the cylinder forcing the pistons to move outward, the brake shoes are pushed against the inside of the brake’s drum. This action causes the friction component found on the outside edge of the brake shoes to come into contact with the brake drum’s inner surface.

Q: What is the difference between a backing plate and a dust shield?

A: A dust shield is different from a backing plate. The backing plate holds the caliper. A dust shield is used to keep the dust from the pad friction on the rotors off of your wheels. Personally I would not want the dust shield. You must have the backing plate, but a dust shield is optional.

Q: What material is used for backing plates?

A: There are four main types of backing plate materials: plywood, aluminum, stainless steel, and G10 fiberglass board. The average boat has plenty of hardware, all requiring backing plates. A common choice for making backing plates is marine plywood. The plywood should have no voids and multiple thinner plies.

Q: How should backing plates struts levers and other metal brake parts be cleaned?

A: Backing plates must be dry cleaned using a cotton cloth to remove the dirt, dust or any other dry contaminant. Struts can be wet cleaned by applying alcoholic solvent. Levers can be cleaned using a mineral spirit. Metallic plates can be cleaned using water based solution or water.

Q: Which of the following components is usually mounted directly to the backing plate?

A: The brakeshoes are generally mounted on a backing plate and are located inside the brakedrum. When expanded by the brake mechanism, the brakeshoes press the brake lining against the brakedrum, which creates friction to stop the rotation of the wheels, which in turn stops the vehicle.

Q: How big should a backing plate be?

A: We suggest either a backing plate extending 1 inches beyond each fastener, or a minimum of 3 inches in diameter for high-load applications. These minimum dimensions increase proportionately for larger bolts. Thick metal washers (a half-bolt diameter) must be used with every backing plate material other than stainless steel.

Q: How thick is a brake pad backing plate?

A: 1/16” thick. The brake pad backing plate should be at least 1/16” thick. If it's thinner than that, it can cause damage to the braking system.

Q: What does a bad backing plate sound like?

A: A scraping or grinding noise from your car or truck's wheels is one. sign there might be something wrong!

Q: What is the best material for a backing plate?

A: The most important factor is the material properties of the backing plates and their expected operating temperatures. Copper, Aluminum, Molybdenum, and Stainless Steel are the main materials used for backing plates. They each have different properties that make them better suited for certain applications.
