Lincoln mark viii brake issue.

Asked by Lincolnmarkviii Dec 11, 2015 at 10:57 AM about the 1993 Lincoln Mark VIII 2 Dr STD Coupe

Question type: Maintenance & Repair

I was driving to work last week, and
while I was driving my brake pedal just
started traveling all the way to the floor.
My abs, and brake warning light are
always on now, and I seem to only
receive actual brakes on my passenger
front wheel. There is no more abs either.

I checked the master cylinder and I have
no idea what I'm looking for, but those
internal spaces on the sides of the brake
fluid container seem to be full. Is there
anyone here that can help me? I'm not
sure if I have a bad master cylinder or
what but I'm seeking someone's
wisdom.

A master cylinder can leak internally, pushing past bad seals without resistance, so the fact it still has fluid does not mean it's still good. A caliper can also leak internally back to the MC, meaning no resistance and no sign of an obvious leak.

Don't drive your car until this problem is fixed as it is unsafe to drive. It does sound like the master cylinder has gone bad but it could be other problems.
