It is true that a new one can be faulty... I have seen that... but I am playing the odds in my guessing.. way more likely not good bleeding...which of course would include someone not bench bleeding the master cylinder properly...

Brake work is relatively simple and requires no special expertise, especially for a car as old as yours. Old leaks require a lot more effort to diagnose. That's why they decided to hit you for an exhorbitantly priced brake job, I suppose. This is a typical strategy to bilk the customer: you tell him that you will fic his car. but it won't be cheap, blah, blah, but when you have paid, your car will be just like new. Then you go to pick it up and it is far from perfect, so you return it, and surprise! you get to pay even more!

You need to make them fix the brakes as promised, and never, never return.

I totally agree with Richard....

Brake pedal intermittently slowly goes to the floor after M/C replacement? Screams fauly M/C to me or at the very least poor workmanship.
No question the shop should fix it. This is a real safety issue and if they balk at fixing the brakes correctly I would not take no for an answer.
Don't take a chance on an accident and possibly hurting yourself or someone else.
Complaints to the BBB and media would be a part of the discussion I had with the service manager at the repair shop.

Alright, she goes in tomorrow for the oil leak fix. I've been mixing Lucas oil stabilizer with the oil and that seems to be slowing the leak substantially so I don't have to run to autozone every day and buy oil. If Lucas sucks, they're changing the oil tomorrow anyways so having it in for a few days won't do anything.

they're also going to check out the brakes. He said that he thinks that pressure in the system built up and is leaking out through another weak spot in the brakes eg old crumbling lines or rubber seals.... there is brake fluid leaking from where the brake booster and the M/C meet. Not dripping but it's wet. Arrrgh just want the brakes and the oil leak fixed!!!!! All i'll need is some new tires and I can take a nice long well deserved drive. I can't wait. she needs to be ready to do a 2,000 mile trip to Texas in the next few months.

I just hope I don't get shot at... Imagine: A slow car, blowing smoke at everyone with California plates in Texas... Might get to my friends house in Austin with a few bullet holes in the body It's all good though, I have a big ol' Texas flag sticker on my rear window, so it should minimize the shooting

Anywho, it goes in tomorrow so I'm excited. they told me it would be same day so I hoping that's the case. About the leaking injector I looks like it's coming from those small hoses. I'll try the vacuum line and see what happens. It's been such a good car though, it's really a trooper, i've already put 1,500 miles on her!
