Brake Discs

The mechanical and thermal stresses acting on the brake disc are extremely high. So it’s important they’re up to the job, and perform just as intended. Like all of our braking products, our discs are made to mirror the OE. So whatever the technology, you can be assured that every Delphi disc has been designed, engineered and manufactured to provide the very best braking performance. Just like the OE. Be it coated, cross drilled or high-carbon…it’s a given.

ECE R90 certified brake discs

It should come as no surprise that our brake discs for new vehicles launched post 1 st November 2016 are R90 certified, alongside a range for popular older applications. After all, we’ve been meeting these quality standards for many years. The only difference today: our discs now undergo official ECE R90 testing schedules including performance, dynamic friction comparison, high load integrity and thermal fatigue analysis to certify that they perform to a prescribed tolerance of the OE part.

Fully coated brake discs

Thanks to a special zinc-flake, silver Geomet coating, our coated brake discs offer greater and longer-lasting corrosion protection compared with many oil-dipped or partially painted and coated equivalents, whilst also being more cosmetically appealing. And because they have no oil to clean off, they save valuable labour and service time. All this makes for a better protected disc that’s easier to install, easier to dismount as well as being easy on the eye too.

High-carbon brake discs

The added carbon content in our high-carbon discs helps to both reduce the risk of thermal cracking under high-temperature loads, and allows the discs to operate at a cooler temperature, for a more consistent braking performance. It also increases their resistance to distortion or warping for added durability, while delivering noise and judder free braking.

Cross-drilled brake discs

As well as looking cool from behind your wheels, our cross-drilled discs will keep your brakes feeling the same way – cool. The cross-drilled holes dissipate heat, brake dust and gases, helping to keep the pad surface cool and clean and reducing the risk of thermal distortion and warping. These same holes also prevent a film of water forming during wet conditions for improved braked response.

Vented brake discs

Our vented discs feature special internal cooling passages to maximise airflow. By continually moving air across the disc’s surface or through the disc itself, they allow more heat to be dissipated, improving both cooling capacity and resistance to cracking from thermal shock.

Brake discs with bearings

To avoid damage to the bearing during removal, and ensure the correct pressing in into the new, we offer a range of discs with these safety critical components already pre-mounted. They also include both toothed and magnetic ABS sensor rings, as per the OE, and the relevant fixing accessories. All for quick and accurate installation.

One-piece cast iron brake discs

Our one-piece cast iron discs offer an aftermarket alternative to BMW’s patented two-piece bi-metallic composite disc. Engineered from a single piece of cast iron, they deliver the same standards of consistency, longevity and braking performance as the two-piece disc, but at a fraction of the price. And to top it off, they come with fixing screws for quicker and easier fitting.

In this article, you will find out about Delphi's Braking systems.

When it comes to braking, speed is a must. In an emergency situation, every second counts – it could make the difference between you having an accident, or not. We apply the same philosophy to our new-to-range braking parts. Making sure we get the right parts to the workshop bay as quickly as we possibly can. Ok, so we’re talking weeks rather than seconds, but timing still matters. Why?

Well, it’s simple. Every time a driver hits the brake pedal, a tiny fragment of friction material wears off the pad. Now think about how many times they might apply their brakes in a typical journey. Especially in stop-go-traffic. And it’s no wonder that they’re often one of the first critical items to be replaced.

Whilst this might be bad news for the vehicle owner, it’s a great opportunity for you, the independent garage. Because unlike other routine service procedures, most vehicle owners will have their pads, inspected, and replaced by a qualified technician. But this is more than just a one-time brake job. Do it well and you could tie in a new vehicle, with plenty more repairs in it, for its entire lifetime. So, you’re going to want to make sure that you have both the right part for the vehicle, and a proven quality part too.

And that’s where we can help. As a manufacturer of the pioneering propulsion technology fitted as OE to many of these vehicles, we work hand-in-hand with the world’s leading automakers, years before launch. Knowing exactly what’s coming and when, means that we can always be one step ahead of the game in terms of new product introductions.

Last year, for example, we introduced new braking parts for the Land Rover Evoque (06/19), Volvo S60 (05/19>), BMW 7 series (03/19>), Mercedes B-class (01/19>) and EQC400 (05/19>), Mazda 3 (01/19>), Toyota Corolla (02/19>) and Supra (06/19>) and Nissan Qashqai (04/19>) and Leaf (01/19>). This year we were first to market on brake pads for the brand new Landrover Defender (2020>) and Volkswagen Golf MK8 (2020>), meaning you can access the repair opportunity even sooner.

This is never at the expense of quality, however. Every one of our braking parts is designed, engineered, and manufactured to very highest OE standards - for brakes that are proven to stop quicker, brake quieter, and last longer. Take our pads; unlike some of our competitors, they feature a special OE underlayer technology that reduces noise, lowers heat transfer and increases the pad’s shear strength. Just like the OE.

The same goes for our discs. Our engineers consider every possible variable when developing a new one, resulting in a range of different disc castings and/or configurations that mirror the OE for fit, form, and function...even if, like the vented vanes in our discs, they are more complicated and costly to cast. In a nutshell, if the OE does it, we do it too.

This winning combination – providing the right parts, for very latest vehicles, in the quickest possible timeframe – means that technicians can fit Delphi’s brakes with complete confidence. Knowing that they’ll be able to perform a best-practice, OE-quality repair, that will guarantee 100 percent customer satisfaction, and with it, safeguard repeat business for years to come.
