Please find out where the replacement parts came from and post here. 
Frankly, I am concerned about the quality of some of the parts out there, and we are talking brakes.

Done. Not only does the servo not work correctly, I have fluid coming out from the master cylinder CAP. This happened to me last Sunday at a car show, and it took me 20 minutes to get the cap off and one blister. Cleaned up, put cap on gently, and tonight there is more fluid leaking from the CAP. Attempted to remove it again, have another blister, and it is still not off. It is clearly also defective.

I have asked them to replace both parts at their expense and do a quality control check to make sure the servo is good and that a human can acutally remove the cap that never leaked on the original part when I took it in.

Thanks Aaron,

Craig

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.

Aaron

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,

Craig H. Nicholls
