My 1995 Chevy Astro Van is:
Has Power steering, A/C and Curise control
1995 Chevy Astro Van, 52,000 Miles, (thatís right 10 years old and 52,000
miles). Has ABS Brakes, Original owner.
1st time: Brakes felt spongy, and had a lot of movement but stopped fine,
only happened once and did not happen again for months. I do not remember
if the ABS came into use at all just before this or not.
2nd time: While running on a very bumpy area approaching a stop sign, I
applied brakes and ABS kicked in. Stopped fine, no other symptoms. At the
very next intersection when I applied the brakes they were spongy and
traveled quite a bit before I felt I had brakes. It stopped fine, but I
was very concerned that I wasn't going to stop in time. (Good thing that I
have a habit of stopping with leaving at least a car length between me and
the next car.) I had brakes but it scared me. The next time I needed to
use the brakes, they felt normal. My husband checked them out and found
everything seemed normal. Couldn't get them to do anything wrong. He
checked: Brake Fluids- fine, Power steering fluid-fine, shoes and discs
were fine, no leaks, lines seemed fine and the brakes worked fine. Then
with in two weeks later number 3.
3rd time: Husband driving-Towing trailer, entering camp ground, big dip
and ABS brakes kicked in again, brake went spongy again, peddle traveled
as before, was able to stop OK very concerned though. Since this episode,
the brakes have not returned to normal. First chance into the shop it
Van is in the shop now, at a Chevy dealer (6 days now), they replaced the
Master Cylinder. Did not help. They talked about contaminated fluid, or
air in line. They said they bled the brakes. They were going to do it
again. When I asked if they replaced the fluids they really didn't answer
They said that the symptoms are intermittent, HE said that he can get it
to act up. They are talking about replacing the Brake Pressure Module
Valve (BPMV) next. Said it was a $1200 part. They are trying everything
they could think of before doing that, they say.
They said the Chevy rep was in the shop today, and they asked him about it
being 10 years old with only 50,000 miles if they could help me out (I
understood it as help with the cost), and he told them it's 10 years old.
They then told me that the head mechanic was going to take a look at it
I can't find the BPMV part that they are talking about in my manual, or so
far on the internet.
Did I even need a new master cylinder at all. Both my husband and I are
wondering if they are just trying on parts until they get it to work.
Since the Master Cylinder didn't fix the problem, should I have to pay for
I asked the service guy, when or if they plugged it into the computer did
it give them any answers, He really didn't answer me there either.
I drive this Auto 99% of the time, the Front Disc brakes were replaced
once at 20,000 miles. A piece of fishing line had wrapped around an area
and caused one wheel Disc to wear a lot, never noticed any pulling at all.
(6 years ago). The rear shoes are original with, at least 50% wear left. I
start and stop gently. (Yes I'm a grandma).
Any ideas? Appreciate your input.
