Here are specific application scenarios of brake pad:
Post-Installation Break-In: Run 300-500km at moderate speeds (avoid sudden hard braking) to ensure full contact between pads and discs—this boosts friction stability by 15% (per ECE R90 guidelines).
Routine Checks: Inspect pad thickness monthly; replace when it drops below 3mm (critical for safety). Wipe off brake dust/debris with a dry cloth—oil stains on friction surfaces can reduce braking efficiency by 30%.
Avoid Overheating: Don’t keep brakes engaged during long downhill drives; intermittent braking prevents temps from exceeding 400℃ (the pad’s max operating limit, per ISO 7884).
