trw Brake Rotor

Brake Rotors

With a continuous research and development program driving a wide range of remanufactured brake calipers, pads, and rotors designed for heavy duty vehicles, you can rely on TRW to provide you with HCV brake rotors that satisfy your customers and help you to build business. We’ll give you exceptional coverage for truck brake rotors, pads, and calipers. Rely on our 100 years of TRW experience and fit it right the first time with TRW commercial vehicle brake pads, rotors, and calipers.

Our truck brake rotors and pads give you:

  • Tight tolerances for hassle-free fitment and comfortable performance
  • HCV Brake rotors and pads that meet and beat OE standards

We supply vehicle manufacturers and the independent aftermarket with more than 12 million brake rotors every year worldwide, so you can put your trust in us when it comes to truck brakes and pads — now and in the future. That’s because we invest in innovation, which brings you not just premium quality parts, but also the latest developments in brake rotor technology so that you can give your customers the best possible service.

Our High Carbon rotors exceed the OE specifications expected by manufacturers; that’s because we design them not just to meet standards but to beat them and be the best real world solution for today’s vehicles. With these rotors, you’ll get great stability, improved thermal behavior, and best performance all round.

Demands on the specification of brake rotors – from weight to braking performance to NVH (noise vibration harshness) properties – are increasing but our High Carbon Rotors will help you to meet them. A growing number of vehicle manufacturers are now introducing High Carbon rotors as standard, so to keep pace with commercial vehicle makers and users, you can rely on strong coverage from our aftermarket range.

Here’s why:

  • High Carbon rotors have optimal thermal conductivity, which ensures more consistent brake performance by enabling the rotors to run cooler.
  • High Carbon rotors are more resistant to distortion, which maintains vehicle performance.
  • High Carbon rotors give better stability and increased resistance to distortion and thermal cracking because of the improved thermal behavior.
  • High Carbon rotors improve the driving experience, with a quieter, vibration-free performance.

One reason why so many businesses rely on us to achieve a faster fit is because our replacement brake pads and disc brake parts come complete with all the essential accessories and fitting kits required. Our Heavy Duty Line range of brake pads is completed by a set of accessories which, combined with the basic product, make it possible to cover the great majority of variations in each individual market. We offer you market-leading coverage from a refined range. That means you can spend less time searching for parts and more time fitting them, keeping jobs moving through the garage to increase business.

We make the safest and highest quality truck brake rotors because we match machining process quality with a finely controlled mixture of raw materials. TRW produces the finest gray cast iron to ensure the best possible mix from the initial casting – and, ultimately, the best end performance quality.

Through exhaustive testing, we ensure:

  • A high carbon content (for a fluidity that enables easier casting and machining, and less shrinkage).
  • A low melting temperature of 2084°F - 2192°F.
  • Robust resistance to wear.
  • A high thermal capacity.
  • Optimised rigidity through high tensile and compressive strength.

Stringent testing of castings before we release them for machining, ensuring the highest possible levels of safety.

We continue to lead the market with a range that provides excellent vehicle coverage and exceptional part quality through precision machining as well as material strength. Machining takes place on CNC production lines capable of maintaining the correct parallelism and flatness. It is controlled by sophisticated measuring instruments, and rotor positioning is ensured by the precise placement of the central and radial holes. The observance of strict tolerances is an absolute guarantee for a minimum DTV (Disc Thickness Variation) and also for a comfortable braking maneuver free of squealing and judder. That’s yet another reason why TRW Aftermarket HCV brake rotors are reliable, dependent, everyday components that you can fit with confidence.

No one knows better than we do how components work together to maximize the power of the braking system; that’s because we produce not only rotors and brake pads but every type of vehicle safety solution, and we understand the best ways to protect the passengers inside every vehicle. Each element is designed and built to be a balanced part of the braking system. That’s why TRW HCV brake rotors and pads mean an easier fit for you, reliable quality for your customer, and a range of robust products that you can use to build your business with confidence.

TRW hcv Brake Pads

Brake pads

As a world leader in part design, manufacture and production, we can produce brake pads that meet the needs of all the major commercial vehicles in the world. With TRW, you can offer drivers performance and safety enhancing brake pads for trucks, trailers, buses and many other heavy commercial vehicles.

The key benefits of TRW brake pads are:

  • One of the most advanced friction material in the world for better efficiency
  • They outperform Original Equipment Service (OES) parts in independent tests
  • High performance testing tracks to test bedding in period and fading and ensure exceptional safety
  • Fitting accessories included in the box
  • Compatibility with state-of-the-art anti-lock braking technology

Importance of brake pads

Brake pads are incredibly important to the output and safety performance of any heavy commercial vehicle. With tougher demands compared to regular cars and vans, heavy commercial vehicle brake pads need to be more robust. By using the latest manufacturing techniques, and with our stringent testing processes, we can provide this. TRW even offers a backing plate part that has been patented and produced completely in-house – resulting in significant improvements in the shear and material contraction properties.

Additional benefits of TRW pads include:

  • Relatively high resistance to brake fade caused by overheating of brake components
  • Ability to recover quickly when wet
  • Braking force is always proportional to the pressure placed on braking pedal

Top of Class

The most important element of the brake pad is the friction material and, through years of research and development we understand what makes the perfect mix for heavy commercial vehicles.

Advancement of brake pad

Disc brakes were only introduced in heavy commercial vehicles in the 1980s, with Renault being the first manufacturer to upgrade from the traditional drum and shoe braking system. With disc brakes needing high quality brake pads, this development has seen a whole host of opportunities open up for manufacturers with TRW at the forefront of all brake pad development.

Growing Market

Europe is the global leader in the Commercial Vehicle (CV) industry and in 2014 vehicle registrations grew by 10.8%, with vans, buses and coaches all increasing significantly. This highlights the need for you to offer quality solutions in the heavy commercial vehicle market.

TRW brake parts are the some of the most respected and trusted automotive components in the world. To maintain this trust we have to consistently provide high quality products, which we achieve through our rigorous testing process.

Many of our tests focus on the fading of brake pads, which is the most critical characteristic of heavy commercial vehicle friction material. We test our products above and beyond the intended use, which means drivers will never find themselves in a situation where they can’t trust the brake pads in their heavy commercial vehicle. Evaluated by independent authorities in the Netherlands, our testing processes include:

  • High performance testing – this assesses the bedding-in behaviour and fading
  • Alpine simulation testing – measuring the downhill braking performance after 12 minutes of continuous braking on a 20% incline
  • Dynamometer test – in conjunction with ECE R90 homologation

The 2014 tests carried out by FRAUNHOFER-INSTITUT in Germany delivered exceptional results, with TRW products lasting longer than any other competitive products under extreme pressure.

We also checked the amount of wear on all parts after every test and, in doing so, discovered that our products can perform better than OE products. This means we not only meet the international regulations, we exceed them.

All TRW products are designed to be as simple and easy to use as possible, including our brake pads. With fitting accessories included in the box you’ll always be able to achieve a fast, efficient fit.

Because heat causes wear and failure in brake pads, we’ve created and patented a system to prevent cracking and deformation occurring between metal support and friction material.

Cavities on the metallic support, help disperse heat from the surface not directly in contact with the pistons. This arrangement improves cooling of the entire braking assembly by increasing both the surface contact between the friction material and backing plate and the dissipation surface of the backing plate itself.
