The maintenance of the brake system requires targeted measures based on specific issues. If decreased braking performance, abnormal noises, or a spongy brake pedal are observed, the brake pad thickness should be prioritized for inspection. When wear is below 2 mm, replacement is mandatory. Simultaneously, examine the brake discs for deep grooves (exceeding 0.5 mm), cracks, or warping - these conditions necessitate immediate repair or disc replacement. Brake fluid should be replaced every 2 years or 20,000 km as it readily absorbs moisture, leading to performance deterioration. During replacement, ensure complete air bleeding from the system and maintain the fluid level within specified limits, using either OEM fluid or DOT4-compliant products. Apply ceramic-based protective coating (rated for 1400°C) to brake pads and lubricate caliper guide pins with full-synthetic grease to maintain mobility. Routine maintenance should include regular cleaning of brake disc surfaces and rust-proof treatment (using 1100°C-resistant aluminum-based compound) for wheel bolt contact areas. If the ABS warning light illuminates or steering wheel vibration occurs during braking, perform professional diagnostics on sensors and control modules. Typical service life is approximately 30,000 km for brake pads and 50,000 km for discs, though actual wear depends on driving habits and road conditions. Inspection every 10,000 km is recommended.
