Millions rely on TRW True Originals brake discs
As industry-recognised global braking specialists, TRW produce over 12 million brake discs every year for vehicle manufacturers and the independent aftermarket. TRW True Originals are just that; originals that are never just a copy of an existing model. TRW design and build everything from the ground up to meet the real world challenges your customers face, and because they never stop researching and developing new safety and performance features, you’ll always have access to the latest developments in braking technology for your vehicle.
No cleaning, no delays
Did you know that TRW pack all their brake discs in VCI (volatile corrosion inhibator) paper rather than coating them in oil or rust preventative? You just take them out of the box and get to work - no need to waste time cleaning it off before fitting.
To provide increased corrosion resistance and performance, TRW product developers devised a new industry concept; black painted brake discs. By coating parts of the disc in their specially formulated black paint, we create a unique surface that acts as a protective barrier against corrosion.
Tight tolerances for cast iron disc performance
When TRW manufacture their 'True Originals', they control every detail of every part. Because they’re committed to producing the safest and highest quality brake discs, they use a carefully controlled mixture of raw materials to produce the finest grey cast iron. By undertaking this process, it means that they can be sure of the best possible casting for the best performance quality.
All TRW castings are made to tight tolerances using top-quality EN-GJL-150 or EN-GJL-200 cast iron material.
- Disc thickness variation (DTV) never exceeds 10mu
- Runout never exceeds 30mu
- The central hole is fixed at H8 norm
Castings are subject to stringent safety tests and controls before being released for machining. These close tolerances provide hassle-free fitting for you, and comfortable performance for your customer.
Disc brakes with cast iron safety
Because TRW are 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.
Exhaustive tests ensure:
- High carbon content (the fluidity allows easier casting and machining, plus a low degree of shrinkage)
- Low melting temperature (1140 degrees C- 1200 degrees 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, giving you outstanding performance and safety for your journey.
