5k steering and brake retrofit

[blarson@zeiss.com]

    Below is my btdt comments on the pentosin removal conversion described by me
a little while ago on the list.  Thanks to Charles Lamphier and Scott Mockry for
the information that helped me complete this swap.  Please let me know if anyone
has questions, or needs more detail on this conversion.
    I have been driving my 1987 5kcstq after a successful conversion to 1983
steering rack, power steering pump, hoses, and vacuum brake booster.  I am now
completely pentosin free, and happily running on $1.50 per quart automatic
transmission fluid.  The conversion was done due to a bad rack, bad pump, bad
bomb, and leaking hoses.  

The total cost of my conversion is listed below;
    1. vacuum brake booster, vacuum lines, hydraulic lines, atf reservoir, and
core steering   rack that I pulled myself $60 at u-pull it yard
    2. Rebuilt steering rack $250 including tax.
    3. 2 quarts atf, $1.50 per quart.
    4. power steering belt $10

The parts needed to do this conversion are;
    From 1983( 81 to 83 should work) Audi 5000 (old style body), turbo or non
turbo;
    steering rack
    atf reservoir
    all 3 hydraulic hoses
    vacuum brake booster
    vacuum line to brake booster with check valve
    power steering pump
    the outer bracket that mounts power steering pump
    power steering belt from 1983 car(new)
    
The instructions for the conversion are;
    remove tie rod ends from car    
    remove rack from car
    remove all hydraulic hoses from car
    remove brake bomb
    remove hydraulic brake booster
    remove pentosin pump and outer bracket
    install new rack into car
    install hydraulic hoses to rack
    install pump with pre 1984 outer bracket
    hook up pump to hoses(I did not remove hoses from pump when taken from parts
car)
    install tie rod ends(I used post 84 tie rods)
    install vacuum brake booster
        (direct bolt in, just push master cylinder forward for clearance)
    plumb vacuum line to intake manifold with check valve from parts car
    install reservoir 
    install hose from reservoir to pump
    fill reservoir with atf and cycle rack per manual to fill system with fluid
    
I made 1 modification other than this to improve clearance between power
steering pump and radiator, this may not be required on your car, but is listed
below;
on inner power steering pivot mount(same on both cars) I had .100 inch removed
from both levels of the surface that mounts to the block.  I have heard from
others that this is not necessary, but to get greater than .125" static
clearance between pump and radiator I needed to add this modification.

Summary;
    The brake assist after this conversion is fine, the ABS still works, no auto
check warning lights are on, and my Pentosin bill is gone forever. 
    After getting rid of the central hydraulic system as it was, I feel much
better about the hydraulic, and braking systems in this car.  
    Before you all start to flame me, remember that I have used all Audi OEM
parts from the same 5k (including turbo) series cars, and this is almost all a
direct bolt in conversion.
    The car is in the Minneapolis/Saint Paul metro area if anyone would like to
take a peek under the hood.

Thanks
