0 986 479 H40 Brake Disc (BOSCH OE-Spec Replacement)

The 0 986 479 H40 Brake Disc is a BOSCH brake discs listed under our
Brake Discs category at
CG Auto Parts Shop. Every listing includes a full manufacturer cross-reference
table so you can confirm fitment by part number before you order.

How the 0 986 479 H40 Brake Disc Works

A brake disc (rotor) is the rotating cast-iron surface clamped by the brake pads to decelerate the wheel. Heat generated by friction is dissipated through the disc mass and, on vented rotors, through internal cooling vanes that pull airflow through the disc centre as it spins. Disc thickness, runout (lateral wobble), and surface finish directly determine brake feel, stopping distance, and noise behaviour.

Signs You Need a 0 986 479 H40 Brake Disc Replacement

Pedal pulsation felt through the brake pedal or steering wheel signals disc warping or uneven wear. A grooved or heavily scored surface is visible on inspection. Any disc measured below the minimum thickness stamped on its hat is a hard replacement threshold — below-spec discs can crack under heavy braking loads.

Brand & Manufacturing Authority

This brake discs is manufactured by BOSCH, a recognised supplier to the automotive aftermarket. The part number 0 986 479 H40 identifies this specific unit in the manufacturer’s own catalog. It is supplied new — not remanufactured — and is backed by our
warranty policy.

Material & Construction

Built from grey cast iron with a precision-machined friction surface; new discs typically arrive with a corrosion-inhibiting coating on the non-friction surfaces that wears off during bed-in. This construction is chosen to match or exceed the OE
specification it replaces under the same load, temperature, and service conditions.

Fitment Confidence for Your 0 986 479 H40 Brake Disc

Year-make-model filters alone can miss mid-year production changes that affect fitment. The safest
method is to match the part number stamped on your existing brake discs against the
cross-reference table below. If you can’t locate your existing part number, send your vehicle VIN
through our contact page and we’ll confirm before you order.

Product Specifications

Cross-Reference Compatibility Table

Match your existing part number against this table before ordering. All data is drawn directly
from the manufacturer’s own cross-reference documentation.

Installation & Safety Notes

Always replace discs as an axle pair with fresh brake pads, since worn pads have worn into a profile that doesn’t match the fresh disc surface. Torque the disc to the hub in a star pattern and perform a proper bed-in procedure with graduated stops from road speed. Always follow your vehicle manufacturer’s torque specifications and service manual procedure. For the engineering standards that govern this part category, see the SAE International brake system standards.

Quality Assurance

We verify every listing’s cross-reference data against the manufacturer’s own catalog before publishing. We sell BOSCH parts because the brand has a documented track record in the brake discs category. If a part number doesn’t match your vehicle after checking the table above, contact us and we’ll find the correct one.

Choosing the Right 0 986 479 H40 Brake Disc — A Buyer’s Guide

Shopping for a brake discs by part number rather than by vehicle model alone is the most reliable way to avoid a fitment mismatch. A year-make-model filter is a starting point, but the same vehicle model can use different component specifications depending on trim level, engine variant, and production date. The cross-reference table above is built from the manufacturer’s own part-number data, which means the relationship between this part and the vehicle application is confirmed at the component level rather than inferred from model data.

When you receive the new brake discs, compare it physically against the old part before installation — check overall dimensions, mounting hole positions, and connector orientation. A direct visual comparison catches any discrepancy before time is invested in
disassembly. If anything doesn’t match despite the part number confirming correctly, contact us before installing, since we can usually resolve fitment questions the same day.

We source our BOSCH parts directly through authorised supply channels to ensure you receive the genuine part that the cross-reference table confirms. Aftermarket quality varies enormously by brand; listing the actual manufacturer — rather than a generic
“compatible with” label — is how we give you the information needed to make a confident buying decision. The About Us page explains our approach to sourcing and part-number verification in more detail.

After Installation — What to Check

Once the new 0 986 479 H40 brake discs is fitted and torqued to specification, a brief test drive under controlled conditions is the best way to confirm the repair is successful before returning the vehicle to normal use. Listen for any new noises from the affected area at low speed over a rough surface, and confirm that the system behaviour feels correct.

For suspension and steering components, a wheel alignment check immediately after installation is strongly recommended, since even a correctly fitted new part can require alignment correction compared to the worn part it replaced. For braking components, a proper bed-in procedure — a series of graduated stops from road speed — transfers an even layer of friction material and settles the new components before maximum braking loads are applied.

Keep the installation date and part number noted in your service records. This information is required if a warranty claim becomes necessary, and it makes future parts sourcing straightforward since you’ll have a confirmed part number on file. Our warranty
policy page specifies the documentation needed to support a claim.
