[s-cars] argh...first the brake servo, now the rack...

[Peter Schulz]

Folks:

need the list wisdom advice on three issues...

    * Brake assist issue which I believe to be the brake servo...- I 
replaced the bomb with a recharged unit and drained and replaced most of 
the fluid...After the R&R of the bomb, the brake light finally went off 
after a few minutes....but the hard brake pedal after startup did not go 
away, and soon the brake light was on again, constantly now.   I checked 
all the connections at the bomb ( line to brake servo, high pressure J 
hose, return line to the hydraulic reservoir) and see no leakage.  At this 
point, at idle, there is little brake assist, and if I rev the engine for a 
few minutes, I'll get more assist, but after three-5 hard pushes on the 
brake pedal, I get some feedback like pulsing, then eventually the brake 
pedal gets very hard to push....
    * I'm thinking servo, but how does one test the pump, and what led the 
servo to go bad AFTER I replaced the bomb? Did some crap get dislodged?
    * Also observed that rack and servo return line to the pump reservoir ( 
hard T shaped line) on the driver's side rail behind the ABS pump looks 
pretty rusty, will likely have to replace. any BTDTs?
    * Now for the fun part...steering rack clunks hard when turning - 
observed the rack move 1/8 inch on the driver's side against the inner 
fender well - the well looks intact, have to check the other side, but it 
at the very least needs some re enforcement...any BTDTs?


thanks..

Happy monday....NOT
