What is the recommended maintenance schedule for Mercedes B-Class brakes?
Mercedes recommends inspecting brake pads and rotors every 10,000 miles or annually, whichever comes first. Brake fluid should be replaced every 20,000 miles or two years. Regular checks for wear, noise, or reduced braking performance are essential. Always follow the maintenance schedule outlined in your owner’s manual to ensure optimal safety and performance.
Q3 How do I replace the brake pads on a 2011-2018 Mercedes B-Class?
How do I replace the brake pads on a 2011-2018 Mercedes B-Class?
To replace brake pads, first, lift the vehicle and remove the wheels. Unbolt the caliper and slide it off the rotor. Remove the old pads and compress the caliper piston using a brake tool. Install the new pads, reassemble the caliper, and reattach the wheel. Torque bolts to manufacturer specifications (e.g., 85 Nm for caliper bolts). Always test the brakes before driving.
Q4 What should I do if my Mercedes B-Class brakes are squeaking?
What should I do if my Mercedes B-Class brakes are squeaking?
Squeaking brakes may indicate worn pads, contaminated rotors, or improper installation. Inspect the brake pads for wear and replace if necessary. Clean the rotors with brake cleaner to remove debris. Ensure all components are properly lubricated and torqued. If the issue persists, consult a professional mechanic for further diagnosis.
Q5 How can I optimize the braking performance of my Mercedes B-Class?
How can I optimize the braking performance of my Mercedes B-Class?
To optimize braking performance, use high-quality brake pads and rotors designed for the Mercedes B-Class. Regularly check and replace brake fluid to maintain hydraulic efficiency.
