Bosch Brake Disc Set - Vented

Yes, absolutely. The protective oil coating must be thoroughly cleaned off using a dedicated brake cleaner before installation. Failure to do so will compromise braking performance.

These discs are designed for specific Lexus GS models. You must verify compatibility for your exact vehicle model and year using the part number and specifications before purchasing.

Vented rotors have internal passages or vanes that allow air to flow through them. This design helps dissipate heat more effectively, reducing the risk of brake fade during heavy use compared to solid rotors.

It is strongly recommended to replace brake pads whenever you replace brake discs. This ensures optimal performance, even braking surfaces, and prevents premature wear on the new components.

ECE-R90 is a European standard that certifies brake discs meet or exceed the performance, safety, and quality specifications of original equipment manufacturer (OEM) parts.

The bedding-in procedure is critical for new brakes. It typically involves a series of moderate to firm stops from increasing speeds, allowing the brakes to heat up and the pad material to transfer evenly to the disc surface. Always follow the specific instructions provided by the brake pad manufacturer.

The minimum thickness for the Bosch 0986 479 615 brake discs is 16.5 mm. It is crucial to have worn discs machined or replaced if they fall below this limit.

This can sometimes occur after installing new discs and pads. Ensure the bedding-in procedure was followed correctly. Check for proper installation and that the correct pad material is used. Minor noise may subside over time with use.

Verify that the protective oil was completely removed from the new discs before installation. Ensure the brake pads are compatible and correctly installed. Check the brake fluid level and condition, and inspect for any leaks in the brake lines.

This can indicate uneven disc wear or warping, which may be due to overheating or improper installation. Ensure the wheel nuts are torqued correctly. If vibrations persist, the discs or pads may need to be replaced.

A light surface rust can form if the vehicle is not used for extended periods, especially in humid conditions, or if the oiled coating was not fully removed. This usually wears off after normal braking. Significant rust or pitting may indicate a defect or contamination.
