Brake System Inspection
After fresh oil and a new filter protect the engine, shift focus to the brakes—your primary safety system. You’ll inspect front and rear discs, pads, and perform a caliper inspection to confirm even wear and free movement. Check brake fluid level and clarity; low or contaminated fluid undermines hydraulic response and freedom from unexpected failure. Verify the parking brake engages and releases reliably so the car won’t betray you when parked. Spotting wear early saves you from costly repairs and keeps control in your hands. Stick to the recommended schedule—this disciplined check at 7,500 miles preserves the Sonata’s long-term reliability and lets you drive liberated, confident the braking system will do its job.
Tire Rotation & Pressure
Rotate your tires every 7,500 miles and check pressure regularly to preserve even tread wear and maintain fuel efficiency. You’ll protect grip, avoid premature replacements, and keep control when it matters. Use the driver-side door placard for exact tire pressure specs and confirm PSI before long trips.
- Set rotation frequency at 7,500 miles to match oil changes.
- Check tire pressure (about 32–35 PSI) when cold for accuracy.
- Inspect tread depth and look for uneven wear during rotations.
- Correct underinflation immediately to prevent poor economy and blowouts.
- Record each rotation and pressure check to track trends and act early.
You’re taking deliberate steps to stay free from breakdowns and costly surprises.
