FAQs

Do I need to replace both brake discs at the same time?

Yes, brake discs must always be replaced in pairs on the same axle to ensure balanced braking performance and prevent uneven wear.

Do I need to replace brake pads when changing discs?

Yes, it is a requirement and highly recommended to fit new brake pads whenever brake discs are replaced to ensure optimal performance and safety.

What does 'ECE-R90 certified' mean for these brake discs?

ECE-R90 certification means that these brake discs meet or exceed the performance standards set by the European Economic Commission for original equipment replacement parts, ensuring safety and quality.

How do I clean the oiled coating from the discs before installation?

Use a dedicated brake cleaner spray and a clean cloth to thoroughly remove the protective oil coating from the braking surfaces of the disc before mounting.

Are these brake discs suitable for all vehicles?

No, compatibility must be verified using your vehicle's identification details. These discs have specific dimensions (239mm diameter, 20mm thickness, 4 holes) for particular vehicle makes and models.

What is the main benefit of the vented disc design?

The vented design allows for better airflow through the disc, which helps to dissipate heat more effectively, reducing the risk of brake fade and improving consistent braking performance, especially under heavy use.

Can I install these brake discs myself?

Bosch recommends that all brake system work should only be carried out by trained specialists due to the critical nature of safety components.

Troubleshooting

Brake judder or vibration during braking

This could indicate uneven disc wear or a problem with the wheel hub. Ensure discs were properly torqued and that the hub is clean and free of damage. If the issue persists, the discs may need replacement.

Squealing or grinding noises during braking

This often relates to brake pads. Ensure new pads were installed with the new discs and that they are compatible. Check for debris lodged between the pad and disc, or ensure the pad mounting hardware is correctly installed.

Reduced braking effectiveness

Check for excessive heat buildup (brake fade), which can be caused by overheating. Ensure the brake pads are properly seated and that there are no leaks in the brake lines. Verify that the correct disc and pad combination is used.

Corrosion on new brake discs

A light surface rust from the oiled coating is normal and should be cleaned off with brake cleaner before installation. Significant rust or pitting may indicate improper storage or handling.

Setup, Compatibility & Care

Compatibility: Before purchasing, it is essential to use the vehicle identification to confirm that the Bosch BD28 brake discs (0986478017) are compatible with your specific vehicle. Always observe any listed restrictions.

Installation: Brake discs must be replaced in pairs. When replacing brake discs, new brake pads must also be fitted concurrently. Due to the critical nature of braking systems, all work should only be carried out by trained specialists.

Preparation: The oiled surface treatment on the brake discs is designed to protect against corrosion. This oil must be thoroughly cleaned off using a suitable brake cleaner before installation to ensure optimal braking performance and prevent contamination of the new brake pads.

Care: Regular visual inspection of brake discs for wear, damage, or signs of corrosion is recommended during routine vehicle maintenance. Ensure that brake pads are also inspected and replaced as needed to maintain system integrity.
