What maintenance is required for the brakes on a 1997-2001 Infiniti Q45?
Regular maintenance includes inspecting brake pads and rotors every 10,000 miles. Replace pads if thickness is below 3mm. Brake fluid should be flushed every 30,000 miles or every two years. Inspect brake lines for leaks or damage annually. Ensure calipers are functioning properly and lubricate sliding pins every 20,000 miles. Follow the manufacturer's guidelines for specific intervals and procedures.
Q3 How do I replace the brake pads on a 1997-2001 Infiniti Q45?
How do I replace the brake pads on a 1997-2001 Infiniti Q45?
To replace brake pads, first lift the vehicle and remove the wheels. Unbolt the caliper and hang it securely. Remove old pads and compress the caliper piston using a C-clamp. Install new pads and reassemble the caliper. Torque caliper bolts to 22-26 ft-lbs. Repeat for all wheels. Test brakes before driving. Consult the service manual for detailed torque specifications and safety precautions.
Q4 What should I do if my brakes are making noise or vibrating?
What should I do if my brakes are making noise or vibrating?
Noise or vibration often indicates worn pads, warped rotors, or debris in the brake system. Inspect pads for wear and replace if necessary. Check rotors for uneven wear or warping; resurface or replace as needed. Clean calipers and ensure proper lubrication. If issues persist, inspect wheel bearings and suspension components. Always address brake issues promptly to ensure safety.
Q5 How can I optimize the braking performance of my 1997-2001 Infiniti Q45?
How can I optimize the braking performance of my 1997-2001 Infiniti Q45?
To optimize braking, use high-quality brake pads and rotors designed for your vehicle. Upgrade to slotted or drilled rotors for better heat dissipation. Use DOT 4 brake fluid for improved performance under high temperatures. Ensure proper bedding of new pads and rotors. Regularly inspect and maintain the brake system. Avoid aggressive driving to reduce wear and extend brake life.
