About this product
When warning contact brake pad wear performance matters, the BREMSI WI0777 delivers — built to the same dimensional and material standards as the original part it replaces. The part is built to the following specification: Fitting Position: Front Axle, Brake Type: Steel, Warning Contact Length [mm]: 450 mm. Each dimension is checked against the OEM reference to ensure the component seats and functions correctly first time. Compatible with AUDI vehicles; use the vehicle selector above to confirm exact fitment for your make, model, and engine variant. Fitment data is sourced from TecDoc, the authoritative European parts catalogue. This part supersedes original equipment references: 1197302300, 17-1416, 1 987 473 566, 1 987 473 583 and 18 more. Matching these numbers confirms a like-for-like replacement with no loss of function. BREMSI is a recognised supplier of automotive braking components to independent workshops and dealer networks across Europe. All parts are sourced from authorised distribution channels and carry full manufacturer traceability — you receive exactly the same component supplied to professional garages and dealer workshops. If fitment or specifications do not match your vehicle, our technical team can help identify the correct alternative — use the vehicle selector or contact us with your VIN for a guaranteed-fit recommendation.
