brakes lost, 86 coupe GT, part II

["kevin kraus" <kevinkraus@usa.net>]

More about the  3 time loss of brakes in my 86 coupe GT.

What I noticed was the fluid leaking out at the right rear wheel.
All three times.
First time they replaced the line, 
telling me that another section of the line broke
once they filled the system....
second time they repaired the line at the same break, gratis,
but said that this was the fault of the parking brake cable,
charging me for that.

Today who knows.
The only symptoms that I experienced
were these...

I saw that the brake fluid reservoir was low,
so I refilled it.  
I was travelling and waited to get back to my local shop.
I did not notice any leakage at that time, but only did a cursory check.
I traveled for a thousand more miles that week.
I did not drive for a few days afterwards.
When I started the car, 
I immediately noticed a sagging as I depressed the brake pedal.
I could still slow and stop the car, but I knew there was trouble.
So I went to the shop.  the trouble was only beginning.
THe symptoms the second and third times were the same,
ie., sagging, leaking.

This shop is Advantage Auto at 14th and R NW, DC
Know a good shop in the DC area for Audi brakes?
THanks for your response.
