Had an odd experience with my 2001 210 wagon. Was out of town for several weeks. Car sat at home in the garage, undriven the entire time. When I returned the brakes were very soft and the pedal travel was very long. Normal driving required taking the brake pedal to within an inch or two of the floor.

The car is about due for an "A" service and brake fluid flush anyways, so I got started on the work. Rotated the tires and inspected the brake components at all four corners. No signs of any damage, flexible hoses in good shape, no fluid leaks, pads are at least 75% at all four corners, bleed valves were all tight. Brake fluid reservoir was full. Brakes were last bled 2.5 years ago.

So I bled the brakes, and all is well. Pedal feel is firm, pedal travel is short, the brakes work, well, like Mercedes brakes again.

Anyone ever experience this? Or have an explanation? In the past I've had brakes get squishy over time - a matter of years. But this has me a bit worried there is some fault in the brake system. Is there anything else which should be checked out?

Thx,
