[TR] New brake master and servo question/issue/safety

[Acekraut11]

 Craig,

My brakes work the exact same each time.  You absolutely should take the car
back again, and again, until they get it right.  If necessary they should
replace the servo and see if that is the problem.  Regardless, you have been
lucky a couple times.  It could happen again when you try to brake because
someone stops quickly in front of you or a kid runs out in front of you.  You
might not be as lucky the next time.

Subject: [TR] New brake master and servo question/issue/safety


To the list,

1972 Triumph TR6, returned from some work at local British car shop.

Had leaking brake master cylinder.  They evaluated the brake master, it was
toast.  Evaluated servo unit, it was full of fluid.  They do not do rebuilds.

So, new master, new brake server, new fluid, bled the brakes.  Drove for a
week,
was really surprised on how soft the brake was since before the repair it was
hard as a rock.  The servo is nice and gives you better control of brake
pressure.

Issue, went to a car show last weekend about 45 miles out.  Came back, got off
the highway, came to the first stoplight, pressed on the brakes and I had no
servo assist.  Did get stopped but just barely.  Notified the shop, they have
a
45 day parts and labor warranty and they were very nice as always.

So, I have been driving the car as much as possible to test it out.  The servo
has cut out on me maybe 4 times in the past two weeks, usually if I come off
the
brake and then go back in, it is ok.  Where I have had a problem is coming
home
tonight pulling into a parking spot, hit the brakes, no assist and I almost
hit
the concrete in front of me.

I am concerned by the fact that I do not do brakes because they need to be
right
and I drive both of my kids in the car.  When I hit the brakes, I expect them
to
be the same each time I hit them.  This issue seems to be (at least to me)
related to the vacuum boost that comes from the engine because it seems to
happen the most at low speed.

What do you say list?  Should I expect the brakes to react and "feel" the same
each time I depress them with this new equipment or is it another one of those
fun "British car things".  Any input is appreciated, if it is not right, I
will
let them deal with it.

Thanks,
