The car:

1986 300E
200,000+ miles
abs system

The parking brake was always loose- would hold on small hills, but not on large hills. I rarely use it, and have not used it in the last month.
What are the symptoms of master cylinder failure? How does the pedal feel (change)? The brake pedal felt normal before the problem, although normal for me may have not been normal. Is there any way to check the master cylinder? The part is not too expensive, so I may replace that too....any suggestions
