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

Brake fluid is an essential part of the braking system. It acts as part of the hydraulic system which allows the brakes to function correctly. There’s a lot to remember about testing and checking brake fluid, so here’s a reminder.

Brush up on brake fluid with this helpful video from the expert technicians at Delphi. We’ll go over some of the most important information ready for the next time you tackle these issues, including:

Where to locate the brake fluid reservoir
What the different DOT ratings mean
When to check and when to change brake fluid.

What brake fluid do I need?

You can find out which brake fluid the vehicle in question needs by looking at the cap on the brake fluid reservoir. There should be a DOT number written on there, which will tell you which specification you need.

How often should brake fluid be changed?

We recommend checking a vehicle’s brake fluid once a year, and changing it every two years to help your brakes stay in good shape.

What does brake fluid do?

Through hydraulic pipe, brake fluid converts the moment of the brake pedal, to the movement of the pad or shoe, on to the disc or drum. It also acts as a lubricant to keep the moving parts of the system working effectively.

How do I check brake fluid level?

Simply find the brake fluid reservoir in the engine bay. You can check the level of the brake fluid with a look at the clearly marked level indicators for Min and Max level. The ideal level is between these two markers.

The fluid should also be checked for water content, as brake fluid will absorb water over time.
