FAQs

Do these brake discs come with new brake pads?

No, this set includes only two solid rear brake discs. New brake pads must be purchased and installed separately.

Why must brake discs be replaced in pairs?

Replacing brake discs in pairs ensures balanced braking performance between the left and right sides of the vehicle. Replacing only one disc can lead to uneven braking, reduced control, and potential safety hazards.

What does ECE-R90 certification mean?

ECE-R90 certification means that these brake discs have met or exceeded the performance standards set by the European Economic Commission for original equipment parts. This ensures they offer equivalent safety and performance.

How do I clean the oiled surface before installation?

The oiled surface is a protective coating. It is designed to be compatible with brake pads and usually does not require cleaning before installation. However, follow the specific instructions provided by the installer or the vehicle manufacturer's service manual.

What is the lifespan of these brake discs?

The lifespan of brake discs varies greatly depending on driving habits, vehicle load, and environmental conditions. However, Bosch products are engineered for durability and extended service life when properly installed and maintained.

Can I install these myself?

No, Bosch strongly recommends that brake system components, including brake discs, should only be installed by trained automotive specialists due to the critical safety implications.

What is the diameter and thickness of these discs?

Each brake disc in this set has a diameter of 259.7 mm and a thickness of 9.2 mm.

Troubleshooting

Brake judder or vibration

This can be caused by uneven disc wear, contamination, or improper installation. Ensure discs were installed correctly in pairs and that the mating surfaces on the hub are clean. Bedding-in procedure might also need to be repeated.

Noise during braking (squealing or grinding)

Ensure new brake pads were installed with the discs and that all components are correctly seated. Check for debris caught between the pad and disc. Persistent noise may indicate a manufacturing defect or an issue with the brake system.

Reduced braking effectiveness

Verify that new brake pads were installed and are properly bedded in. Check brake fluid level and condition. Ensure no air is present in the brake lines. Professional inspection of the entire braking system is recommended.

Visible rust on the surface

A light surface rust film is normal on oiled discs, especially after exposure to moisture. This should disappear after the first few braking applications. Heavy or persistent rust may indicate a deeper issue or prolonged exposure to harsh conditions.
