Which vehicles are compatible with the BREMBO 09.8004.4X?

For which Alfa Romeo models is the BREMBO 09.8004.4X brake disc suitable?

This brake disc is specifically designed for sporty variants of the Alfa Romeo MiTo 955 (2008–2018), providing enhanced braking performance for this compact vehicle. The perforated design perfectly complements the MiTo's dynamic character while ensuring reliable stopping power in all driving conditions. Most Alfa Romeo MiTo 955 variants do not use these brake discs, however, and you should always check the VIN and PR code to check if your vehicle uses them.

Installation instructions for BREMBO 09.8004.4X

1. Replace brake discs in pairs to ensure balanced braking performance across both front wheels.

2. Consult the vehicle's service manual for the specific removal sequence and torque values.

3. Remove the wheels and carefully detach the brake caliper. Support the caliper with wire to prevent stress on the brake hose.

4. Remove the old disc: Loosen the retaining screw. If seized, apply penetrating oil.

5. Thoroughly clean the hub surface from rust, dirt and brake dust before installing the new BREMBO disc.

6. Install the new perforated disc and fresh brake pads, then tighten the retaining screw and caliper bolts to manufacturer specifications.

7. After installation, pump the brake pedal several times to seat the pads and check brake fluid level.

8. Bedding-in: Follow the vehicle manufacturer's recommendations; if none are provided, drive for at least 200 km using gentle, brief brake applications, avoiding hard braking and ABS activation during this period.

FAQ: BREMBO Xtra Brake Disc 09.8004.4X

Do the brake pads need to be replaced at the same time as the BREMBO brake disc 09.8004.4X?

Yes, it is strongly recommended to replace brake pads together with new BREMBO discs. This ensures optimal surface contact between the new perforated disc and fresh pad material for maximum braking performance.

Is the BREMBO brake disc 09.8004.4X ventilated or solid?

This brake disc is both perforated and ventilated. The internal cooling vanes combined with the perforated surface design provide exceptional heat dissipation, preventing brake fade during aggressive driving.

How should new brake discs be properly bedded in?

During the first 200 km, avoid heavy braking and allow gradual heat cycling. Perform moderate braking cycles to develop an even friction layer on the perforated surface, which optimizes both performance and longevity.

What is the outer diameter and thickness of this brake disc?

The outer diameter is 305 mm with a thickness of 28 mm – specifically engineered for the front brake system of sporty versions of the Alfa Romeo MiTo 955 to provide enhanced stopping power over standard discs.

Is this brake disc suitable for vehicles with ABS?

Yes, the BREMBO Xtra 09.8004.4X is mainly compatible with ABS-equipped Alfa Romeo MiTo models that use 305x28mm brake discs. The perforated design maintains proper ABS sensor operation while providing superior braking performance.

Do I need special tools to install the BREMBO brake disc?

No special tools are required for installation of the BREMBO disc. Standard automotive tools including Torx bits, caliper piston spreaders, and socket wrenches are sufficient, though a torque wrench is essential for proper bolt tightening specifications.

What are the advantages of the BREMBO brake disc 09.8004.4X compared to other models?

The BREMBO Xtra series offers superior heat dissipation through perforated design, a corrosion resistant UV coating, exceptional performance, and BREMBO's racing-proven metallurgy for extended service life and consistent performance.

Can the perforated design cause increased brake pad wear?

When properly bedded in, the perforated surface actually promotes even pad wear distribution. The holes help evacuate brake dust and gases, maintaining consistent friction characteristics throughout the pad's service life.

What is the minimum thickness specification for this brake disc?

The minimum thickness for safe operation should not fall below the manufacturer's specification of 26.5mm. Regular measurement during brake inspections ensures the perforated disc maintains structural integrity and optimal performance.

How does the perforated design affect braking performance in wet conditions?

The perforated surface design significantly improves wet weather braking by quickly evacuating water from the contact area, reducing the risk of brake fade and maintaining consistent stopping power in adverse conditions.
