Spongy Brake Pedal on Mercedes SL
Summary of the thread
A 2003 Mercedes SL with a spongy brake pedal and low brake fluid may indicate worn brakes or a more serious issue. Possible causes include air in the brake lines, a fluid leak, or worn brake pads and rotors. It is advised to inspect the brake system for leaks and check the condition of the pads and rotors. If no leaks are found and the pads are worn, a failing master cylinder could be considered, though it is less likely without complete brake failure. Ultimately, professional inspection and repair are recommended to ensure safety.

Thanks I will check the pads and rotors. If there's no leak and the pads are worn, could the master cylinder be failing? I've heard that can cause similar issues.

A failing master cylinder is possible, but less likely without complete brake failure. With the mileage and low fluid, worn brakes are most likely. Get it checked professionally, as hydraulic brakes are crucial.

I took it to my mechanic, and you were right. The front pads were shot. New pads and rotors, lines bled, and all is normal. Cost 480€, but worth it. Thanks for the help.

Low brake fluid and a spongy pedal usually mean air in the lines or a leak. Check your pads and rotors for wear. Low fluid happens as calipers extend. Inspect brake lines and connections for leaks. Any fluid under the car?
