1992 190E 2.6 (201,000 miles)
About once a day the brake peddle travels very near the floor.
I slightly panic, pump the brakes and all is well the rest of the day.
The brake reservoir is full, with no leaks on the parking lot. Brake calibers are dry.
Obviously something is wrong - please provide your suggestions
I'm guessing the Master Cylinder is leaking or something.
About 2,000 miles ago I replaced the front pads and rotor, pushed the piston in and such.
Thanks for the help.
