For North American truck fleets, frequent replacement of brake shoes and repair kits will greatly increase operating costs. Scientific and standardized daily maintenance can effectively extend the service life of brake parts by 30% to 50%. First, develop standardized braking habits: avoid continuous heavy braking during long downhill sections to reduce brake high-temperature aging and glazing. Second, complete pre-trip brake inspection every day: check brake shoe surface wear, accessory tightness and oil contamination, and eliminate hidden dangers in advance. Third, replace accessories in sets: always replace brake shoes in complete axle sets, and update matching repair kits synchronously to avoid performance imbalance of new and old parts. Fourth, regular system debugging: check and adjust slack adjuster clearance regularly to ensure synchronous operation of left and right brakes. Fifth, avoid oil and grease contamination: inspect wheel seals regularly to prevent oil leakage from polluting brake linings. Sixth, run-in new parts gently: perform gradual low-load braking for new brake shoes before heavy-load operation to stabilize friction performance.
