Mercedes-Benz 400SEL brake goes to floor requiring pumping to stop on Mercedes-Benz 400SEL

Some Mercedes-Benz 400SEL owners report experiencing issues with the brake pedal going all the way to the floor, which may require pumping to stop. This problem can indicate the presence of air in the brake lines, resulting in a spongy pedal feel. Additionally, a leaking brake fluid can lead to a loss of hydraulic pressure in the braking system. Other potential causes include sticking brake calipers, a plugged rubber brake hose, or a faulty master cylinder, all of which can contribute to soft brakes. Owners are advised to check for leaks in the brake lines, inspect the brake calipers and hoses, and ensure the master cylinder is functioning correctly. In some cases, replacing calipers and brake hoses may be necessary if a bad caliper piston seal or brake hose is identified. Prompt attention to these issues is crucial for maintaining the safety and proper functioning of the vehicle's braking system.
