Product Information

Full details

This Bosch 2 x Vented Brake Disc Set is designed for the front axle of vehicles requiring reliable and durable braking performance. It offers a key benefit of OE-quality replacement for enhanced safety and stopping power. A caveat is that precise vehicle fitment must be confirmed using the make and model tool or by contacting support, as direct visual compatibility is insufficient. Key features include a 320mm outer diameter, 28mm thickness, 5-hole bolt pattern, 68mm centering diameter, and an oiled surface finish meeting ECE-R90 norm.

Extended Product Information

FAQs

Are these discs a direct replacement for my original front brake discs?

These discs are designed as direct OE replacements for vehicles that originally came with 320mm vented front brake discs with the specified bolt pattern and dimensions. You must confirm fitment for your specific vehicle using the make and model tool or by contacting us.

What does 'vented' mean for brake discs?

Vented brake discs have internal vanes or air channels that help to dissipate heat more effectively than solid discs. This is crucial for preventing brake fade during heavy or prolonged braking.

What is the ECE-R90 norm?

The ECE-R90 norm is a European regulation that ensures replacement brake parts meet or exceed the performance of original equipment parts in terms of safety, performance, and durability.

How do I clean the oiled surface before installation?

The oiled surface is a protective coating. It should be cleaned off using a dedicated brake cleaner and a lint-free cloth before installation to ensure proper contact between the brake pads and the disc surface.

What is the bolt hole circle diameter?

The bolt hole circle diameter (PCD) is the diameter of the imaginary circle that passes through the center of the bolt holes. For this disc, it is 114.3mm, which is a critical measurement for ensuring the disc fits the vehicle's hub correctly.

Can I use these discs on the rear axle?

No, these discs are specifically designed and listed for the front axle of compatible vehicles. Rear axle brake components are different and require specific parts.

How long does the oiled finish last?

The oiled finish is primarily for protection during shipping and storage. It should be cleaned off prior to installation. Once installed and used, the disc surface will be exposed to the elements and braking friction.

Troubleshooting

Brake judder or vibration

This can be caused by uneven disc wear, improper installation, or debris. Ensure the hub face is clean, the discs are torqued correctly, and the brake pads are properly bedded in. If the issue persists, the discs may need replacement.

Squealing or grinding noise

Typically indicates worn brake pads or debris between the pad and disc. Inspect brake pads for wear and check for any foreign objects. Ensure the correct type of brake pads are used for the disc.

Reduced braking performance

Check for brake fluid leaks, air in the brake lines, worn pads, or glazed discs. Ensure the discs and pads are compatible and have been properly bedded in. Consider a full brake system inspection if performance does not improve.

Disc surface appears rusted

A light surface rust is normal on oiled discs, especially after exposure to moisture. This will typically be removed during the first few braking applications after installation. Heavy, pitted rust may indicate a defect or prolonged exposure to harsh conditions.

Setup, Compatibility & Care Instructions

Setup & Installation:

These brake discs are designed for the front axle and require professional installation. Ensure the vehicle is properly supported on jack stands and the wheels are removed. The old brake discs and pads should be removed according to the vehicle manufacturer's specifications. Before fitting the new Bosch discs, clean the oiled surface lightly with a brake cleaner to ensure optimal pad contact. Install the new discs onto the hub, ensuring correct seating. Reassemble the brake caliper and pads. It is highly recommended to bed in new brake pads and discs according to the pad manufacturer's instructions to achieve optimal performance and longevity.

Compatibility:

  • Dimensions: 320mm Outer Diameter, 28mm Thickness, 68mm Centering Diameter.
  • Bolt Pattern: 5-Hole.
  • Bolt Hole Circle Diameter: 114.3mm.
  • ECE Norm: ECE-R90 compliant.
  • Axle: Front.

*Crucially, always use the vehicle make, model, and year selection tool on the product page or consult your vehicle's manual to confirm fitment. Cross-references are available for brands including APEC, ATE, Bendix, Brembo, Delphi, Ferodo, FTE, and Girling, but direct confirmation is essential.* If you are unsure, please contact customer support for assistance before purchasing.

Care:

After installation, avoid heavy braking for the first 100-200 miles (bedding-in period). Regular checks of brake pad wear and disc condition are recommended during routine vehicle maintenance. If any unusual noises or vibrations occur during braking, inspect the braking system immediately.
