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.

Resource Highlights

In this article, you will learn about our tech tips and recommendations for servicing brakes. 

When performing a braking service, it is recommended to fit new braking accessories with every replacement as re-using the old items can jeopardize braking performance.

By replacing accessory kits when changing brake pads, you ensure a reduction in potential warranty claims, a reduction in possible brake noise, and increased customer satisfaction.

Worn Pads

If the inside pad is worn more than the outside one, the caliper needs to be serviced or replaced because the caliper piston has not retracted properly.

If the outside pad is worn more than the inside one, the mounting hardware is causing the caliper to hang up and not slide. If this is the case, replace the mounting hardware and lubricate the slides.

Even wear is desirable although a slight variation in thickness from one pad to the other is considered to be acceptable.

Brake Fluid

Brake fluid with a dry boiling point of 200°Celsius or less should be replaced, and anything under 180°Celsius is potentially harmful and requires immediate action.

The problem is not linked to age or mileage. Regular testing on all vehicles is critical. 

Routinely Test

Routinely test all vehicles that come into your workshop.

This two-minute check could generate extra revenue for your shop and help to ensure safer vehicles.

DS Diagnostics Tool

To ensure the vehicle's braking system is working to its optimum performance, use your Delphi DS Diagnostics tool.
