Installation instructions for ATE 24.0124-0232.2

1. Replace brake discs in pairs to ensure balanced braking performance and maintain vehicle stability.
2. Remove the wheels and carefully detach the brake calliper. Support the calliper with wire to prevent stress on the brake hose.
3. Remove the old disc: loosen the retaining screw using appropriate Torx bits. If seized, apply penetrating oil and gently tap with a rubber mallet.
4. Thoroughly clean the hub surface from rust, dirt and old adhesive residue before installing the new two-part disc.
5. Install the new perforated disc ensuring proper alignment of the two-part construction, then install new brake pads and tighten all bolts to BMW specified torque values.
6. After installation, pump the brake pedal several times until firm, check brake fluid level and top up if necessary.
7. Bedding-in: perform 8–12 progressive braking cycles from 80 to 30 km/h to allow proper friction layer formation on the perforated surface.

Do the brake pads need to be replaced at the same time as the ATE 24.0124-0232.2 Brake Disc?

It is strongly recommended to replace brake pads when fitting new brake discs, especially with two-part perforated discs. This ensures optimal surface contact and prevents uneven wear patterns that could compromise the perforated design's effectiveness.

Is the ATE 24.0124-0232.2 Brake Disc ventilated or solid?

This brake disc features both perforated and ventilated design. The two-part construction with internal cooling channels and surface perforations provides superior heat dissipation, making it ideal for high-performance BMW applications.

How should new brake discs be properly bedded in?

During the first 300 km, perform frequent progressive braking while avoiding heavy braking and overheating. Brake lightly but often, ideally slowing from moderate speeds without coming to complete stops when possible. The perforated surface requires careful bedding-in to develop an even friction layer across all contact areas, maximising the disc's performance potential.

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

The ATE 24.0124-0232.2 brake disc has an outer diameter of 350.0 mm and thickness of 24.0 mm with 5x120.0 bolt pattern – specifically engineered for BMW's high-performance rear brake systems requiring larger diameter discs.

Is this brake disc suitable for vehicles with ABS?

Yes, the ATE 24.0124-0232.2 is compatible with vehicles equipped with ABS, DSC and other BMW safety systems. The two-part perforated design maintains consistent surface characteristics required for proper ABS function.

Do I need special tools to install the ATE 24.0124-0232.2 Brake Disc?

Standard BMW service tools are required including Torx bits, socket wrenches, and most importantly a calibrated torque wrench. The two-part construction requires precise torque specifications to ensure proper assembly and performance.

What are the advantages of the ATE 24.0124-0232.2 Brake Disc compared to other models?

The two-part perforated design offers superior heat dissipation, reduced weight, improved pedal feel, and enhanced braking performance. The perforations help evacuate brake dust and water while the ventilated channels prevent heat buildup during aggressive driving.

Can the ATE 424232 Brake Disc be used for track driving?

Yes, the two-part perforated and ventilated design makes this disc suitable for track use. The enhanced cooling properties and robust construction can handle the thermal stress of repeated hard braking on BMW E90, E92, E93, and E82 M models.

How long do ATE brake discs typically last?

With proper maintenance and normal driving habits, the ATE brake disc 350.0x24.0 mm can last 60,000-120,000 km. Lifespan varies significantly depending on driving style, with city driving, aggressive braking, or track use substantially reducing disc life to 40,000-60,000 km or less. Regular thickness measurements are essential for safety, particularly when operating under demanding conditions.

What is the minimum thickness specification for this brake disc?

The minimum thickness for the ATE two-part brake disc is typically 22.4 mm. When the disc wears below this specification, it must be replaced immediately to maintain safe braking performance and prevent potential failure.
