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.

What you need to know for a complete brake inspection and service

Correctly inspecting and servicing brakes is one of the critical jobs for any mechanic or technician to master. The lifetime of a brake pad can vary dramatically, so it’s essential to be able to identify when they need replacing.

Your 12 essential tips for a thorough brake inspection

Heat cracks
When you’re inspecting discs, keep an eye out for heat cracks. You can do more in-depth tests if you find them with a dial indicator gauge.
Brake fluid level
Always check the brake fluid level and condition. If needed, change the fluids and drain a small amount to allow for the fluid returning from the pistons as they’re retracted . Remove the brake fluid reservoir cap when returning piston to avoid resistance and damaging the system.
Inspect surrounding areas
On brake disc and pad replacement, you should inspect all of the surrounding parts and components for wear and damage. These include steering and suspension parts, bushes, bearings, brake hoses and pipes. Also look at wiring and connectors, shock absorbers and springs, and ABS sensors. If you’re replacing only pads, be sure to remove excess corrosion from brake discs.
Pad thickness
Certain marks on the discs can be a sign of issues with the pad. You should always use a pad thickness gauge to assess levels of wear. It’s typically recommended that brake pads should be replaced if the friction material has worn down to a thickness of 3mm or less. However, your benchmark should always be the manufacturer’s guidelines. Check old pads and discs for signs of overheating and excess dust after a drive.
Symptoms of pad wear
An outboard brake pad with heavy wear can often be a sign of issues with guide pins, bushings and even sliders. If it’s the inner pad that’s showing more wear, you might want to check for a seized piston, or problems with the master cylinder.
Advice on grease
Don’t use copper-based grease on modern brake pads, because it can cause the pads to stick in the caliper. It also has a tendency to attack rubber anti-noise coatings on the pad. Consider using Delphi Anti Seize Braking compound instead.
Anti-noise pads
Anti-noise brake pad components lose their strength over time, which can cause not only increased noise, but also unequal wear and uneven braking. Whenever you replace pads or shoes, you should also renew ancillary parts, including springs, clips and shims.
Brake shoe wear
If you want to know whether brake shoes are worn, look for inconsistent brake pedal feel, or vibration when under braking. The parking brake travel can also be excessive.
Check the springs
Brake shoe return springs don’t last for ever, and they can get weaker with age. If they’re not returning shoes to their original and correct positions, they can cause increase lining wear.
Ensure lubrication
Brake shoe self-adjusting mechanisms should be kept free and lubricated properly.
Brake hose lifespan
Brake hoses are made from rubber, which means they can degrade over time. Typically, you don’t need to replace a brake hose in service until it perishes, cracks or becomes constricted.
Brake fluid temperature
Test the heat of the brake fluid to check that its water content offers the best performance and economy. For the best possible reliability it needs regular calibration.

Don’t forget...

If new brake parts are fitted, you should advise your customers to drive gently for the first 200 miles until they ‘bed in’. This is because excessive braking can potentially damage new parts, and lead to a loss of braking efficiency and performance.

You should also recommend that brake discs or drums are replaced in axle sets, as replacing only one side can cause imbalanced braking performance that leads to premature wear.
