As a car enthusiast, you understand the importance of caring for your vehicle. Beyond regular maintenance, there are specific vehicle parts and system inspections that should be at the top of your checklist. While the inspection can end simply by completing the eye and computed diagnosis, it still has a big effect in the long run. 1. BRAKE SYSTEM INSPECTION Your vehicle's brakes are its most critical safety feature, and neglecting them can have dire consequences. Regularly inspecting the brake system is essential to ensure it functions optimally. Here's what you should check: Brake Pads: Examine the thickness of your brake pads. If they're worn down to 3mm or less, it's time to replace them. Brake Fluid: Check the brake fluid level and condition. Brake fluid should be clear and free from contaminants. Low fluid levels or dirty fluid can compromise braking efficiency. Brake Lines and Hoses: Look for signs of leakage or damage in the brake lines and hoses . Any issues should be addressed immediately. Rotors and Drums: Inspect the brake rotors (disc brakes) or drums (drum brakes) for signs of wear, scoring, or warping.
