Hi

4cyl 98 gl auto. What are the early signs of brake master cyl failure ?

I have a weird "thump" that i feel in the ball of my right foot as go from park to drive 1st thing in the am.

I think that I get a thump for the 1st few times I stop at stop signs.

After the car warms up a bit, there is no "thump".

Ideas ? Car didn't do this 20,000 miles ago.

Thanks,

jim
