12 million reasons to trust TRW brake discs

TRW produces over 12 million brake discs every year, both for original equipment and the independent aftermarket worldwide, so you can put your trust in the market leaders. And because we’re always at the forefront of innovation, you’ll get the very latest new developments in brake disc technology that make sure you can give better service to more customers.

 

Black Painted Brake Discs

TRW original equipment is never just a copy of an existing model – it’s designed and built from the ground up to meet the real world challenges your customers face every day. To provide increased corrosion resistance and performance, our product development division has created an industry first – Black Painted Brake Discs.

By coating parts of the disc in a special black paint, a unique surface is created that adds a protective barrier against corrosion. The paint has been specifically developed by TRW’s original equipment business and provides a gloss finish to the disc (and for the discerning motorist, it looks good, too).

We like to ensure that installers do a great job for customers by helping them to fit fast. That’s another benefit of our Black Painted range. These brake discs are packed in a VCI paper, which is moisture inhibiting. That means we don’t need to coat the discs in oil or rust preventative that has to be cleaned off before fitting. You just take them out of the box and get to work, which saves both time and money.

This innovation is based on the latest insights, discovered through the direct research and development relationships that TRW maintains with major vehicle manufacturers around the world, so that our customers can give added value to theirs.

 

High Carbon Discs

Because they are designed not just to meet standards but also to be the best real world solution, our High Carbon Discs can exceed manufacturer specifications. They provide improved thermal behaviour, great stability and best performance.

High Carbon Discs help meet the ever increasing demands on brake discs in terms of weight, braking performance and NVH (noise vibration harshness) properties. With more vehicle manufacturers introducing High Carbon discs as standard, we’re making sure you can rely on strong coverage from our aftermarket range.

Here’s why:

• Discs produced with High Carbon have optimal thermal conductivity, allowing the discs to run cooler and, as a result, ensure more consistent brake performance

• A High Carbon brake disc is less likely to distort, which means less performance-related problems

• High Carbon improves the thermal behaviour of the discs, giving better stability and increased resistance to distortion and thermal cracking

• High Carbon discs also help to provide a noise and judder-free performance

Boost business with faster brake disc fitting

There’s a wide range of TRW discs that come with fitting screws so that old, worn and corroded fixings never have to be re-used. Fixing screws often get damaged during a brake disc change and cannot be re-used. By including fixing screws with our brake discs, we’ve made it easier, faster and safer than ever for you to replace brake discs. For most of our products, you’ll be provided with all you need in one TRW box. That means you can give the same excellent service, every time – and your customer can rely on the best performance, every time.

 

Tighter tolerances on brake discs

When we design our Original Equipment, we control every detail of every part, and we don’t compromise on raw materials, or on machining tolerances. All our castings are made of top-quality GG20 material or GG15HC for High Carbon. And we keep tight control on three other machining tolerances: the DTV (Disc Thickness Variation) never exceeds 12 µm; the Run Out never exceeds 30 µm; and the central hole is fixed at H8 norm. That means hassle free fitment and comfortable performance without surprises.

 

Disc brakes with cast iron safety

Because we’re committed to producing the safest and highest quality brake discs, a carefully controlled mixture of raw materials is used to produce the finest grey cast iron. Machining process quality isn’t enough – it has to be the best possible mix from the initial casting for the best end performance quality.

Our exhaustive tests ensure:

• High carbon content (the fluidity allows easier casting and machining, plus a low degree of shrinkage)

• Low melting temperature (1140°C- 1200°C)

• High wear resistance

• High thermal capacity

• High tensile and compressive strength, giving high levels of rigidity

The castings then undertake a variety of stringent tests and controls before being released for machining to ensure the highest levels of safety.

 

Enhanced safety with bearings and the ABS sensor ring

We also offer a range of brake discs with integrated bearings, ABS sensor rings and fixing accessories. This makes life much easier when it comes to fitting, as these critical safety components are often damaged when replacing the disc. Using an old, worn or damaged bearing can also increase the risk of damage to the disc itself. TRW’s brake discs with mounted wheel bearings are assembled to ensure the correct pressing in of the bearing. We’ll deliver both toothed and magnetic ABS sensor rings, depending on what is required.

 

All-round safety for TRW brake pads and discs

Because we produce not just discs and brake pads but every type of vehicle safety solution, no one knows better than we do how components works together to maximize the power of the braking system and protect the passengers inside the vehicle. We design and build our discs to be a balanced part of the braking system. That’s why TRW brake discs and pads mean the most efficient fit for you, best quality for your customer, and the best results for your business.
