Ceramic Brake Pads

Selecting Front vs. Rear Axle Specifications

Fleet technicians must select pads based on the specific axle placement and caliper design. Front axle brake pads, such as those for the Jetour X90 Plus, often require configurations designed for big brake calipers to handle higher thermal loads. Rear axle pads, like those for the BYD Dolphin or Hyundai Creta, have different dimensional profiles and often smaller surface areas.

• Front Axle Sets: Sized for high-load friction areas, often packaged as 4-piece sets for big calipers.
• Rear Axle Sets: Designed for stabilizing braking force, with typical widths ranging from 99.6 mm to 101.6 mm.

Verifying Dimensional Tolerances and OEM Compatibility

To prevent brake squeal and uneven wear, match the exact physical dimensions of the existing pad. Precision engineering is critical here. For instance, a rear pad set for a Hyundai Elantra AD or Creta ix25 requires a width of 99.6 mm and a height of 41.7 mm, whereas a BYD Seal or Tang rear pad requires a width of 101.6 mm and a height of 48.9 mm.

• Width and Height: Always measure the backing plate, not just the friction material, to ensure caliper slide alignment.
• Part Number Cross-Referencing: Utilize direct OEM numbers, such as 4H0698451A for Audi A6 platforms, to guarantee compatibility with the vehicle's electronic wear sensors.
