Re: 1988 Town Car brake problem

If you didn't bleed the brakes until bubbles and clean fluid came out after
the master cyl. change, air is a good suspect. I hope you are using some
type of service manual for the work. It should tell you the proper way to
bleed brakes. I always invert a fresh bottle of fluid in the master cyl.
and then bleed the right rear first. I used to flush brakes every coulpe of
years to be sure moisture isn't a problem.

A "whoosh" when hitting the brakes is normal, there is a rubber bellows on
the lever at the firewall. The vacuum side of things is under the hood.
Even if the brake booster had no vacuum, the pedal wouldn't go to the floor.
It would be very hard to puch right from the start but it would be solid.

What led you to replace the master cyl. to begin with?

Re: 1988 Town Car brake problem

The reason for the original change was the brake pedal started all of a
sudden going to the floor. I also repleced the front pads because it was
near that time.

Re: 1988 Town Car brake problem

So it would seem the problem remained after the change. Hmmm... I expect
you have checked for leakage so we can bypass tube replacement and such.

I found that any time I had a soft pedal, flushing the system usually fixed
it. It is the same as bleeding the brakes, just more of it. Bleeding works
best with a helper unless you have a machine to help. Always do the
furthest wheel first. On this car, I would do the right rear, then left
rear. Right front, then the left front. Be sure the fluid doesn't get low
in the master cyl. I think I mentioned earlier, I invert a fresh bottle of
DOT3 in the proper chamber before starting.

I had a car not too long ago that had frozen rear pistons. It was drum
brakes on the rear and a new assembly for each side was quite cheap. That
made a huge difference in stopping but the pedal never went soft or hit the
floor.

I am running out of ideas here - I think better when I am staring at the
machine in question - . Bleed / flush the brake lines would be the next
step for me...

Re: 1988 Town Car brake problem

I forgot to ask, does the car have ABS (Anti-lock brakes)?

Re: 1988 Town Car brake problem

Found out the problem. There was still air in the system and I also had to
replace a leaking brake line and heat up the bleeder valves on the rear
drums to get them off.

Thanks everyone for their help and suggestions.
