SINOTRUK HOWO A7 HOWO T7 SITRAK C7 Brake Pad Set WG9100444150
Installation Location
1. Dual-drive models (6×4 trucks): Installed within the disc brakes on both the left and right sides of the second axle (middle axle) and third axle (rear axle).
2. Single-drive models (4×2 or 6×2 trucks): Installed within the disc brakes on both the left and right sides of the rear axle (drive axle).
3. Wheel allocation: Each kit contains 4 brake pads, sufficient for a complete installation on one axle (2 pads for the left wheel and 2 pads for the right wheel).
Replacement Recommendations
1. Brake Pad Thickness Limit: The total thickness of a new brake pad is approximately 30mm. When the friction material wears down to a remaining thickness of less than 2mm, or when the brake wear warning light on the dashboard illuminates, the pads across the entire axle must be replaced immediately.
2. Brake Disc Measurement: The thickness of a new brake disc is 45mm. Measure the disc thickness with an outside micrometer whenever replacing brake pads; if the thickness falls below 37mm, or if annular grooves deeper than 1mm or through-cracks appear on the surface, the brake discs must be replaced in pairs.
3. Paired Replacement Principle: Brake pads on the same axle (left and right wheels) must be replaced simultaneously. Replacing pads on only one side is strictly prohibited, as this can cause the vehicle to veer sharply during emergency braking.
