  1. NG900 & OG9-3 Workshop
    Howdy. My brakes are feeling a little weak, so I thought in case I might need a booster I got a remanufactured one from Rock Auto. In a bench test, when I sealed tight my vacuum tester tube on the vacuum grommet, there is no vacuum. Does this mean what I just got isn't good? Am I testing it...
  2. 99 & 90 Workshop
    Bad day. I want to weep. I took about three very carefully spent hours to swap in a newly rebuilt, correct model brake booster in my 99. When my work was complete, I got in, started the car, stepped on the brake pedal, stepped a little harder, and then felt an odd "give". I stood up to look at...
  3. 99 & 90 Workshop
    Hi. In the past two months, three professionally remanufactured SAAB 99 brake boosters have failed shortly after being installed on my 1976 99 GL. They are all Centric 160.88043. The brake calipers and brake cylinder seem fine, all also recently remanufactured. I believe the vacuum line valve is...
  4. 9-5 Workshop
    2003 SAAB 9-5 Aero wagon here. Brake system has TCS/ECS So I just replaced my brake booster/servo and all vacuum lines - including the hard plastic line/assembly with the check valves between the brake booster, throttle body, and vacuum pump - and now I have no power brakes! There's no air in...
  5. 9-5 Workshop
    Hi all, 2003 SAAB Aero wagon question: I just replaced my brake servo (added my two cents to this post here), and discovered that the nipple/fitting on the vacuum pump is broken. I need to replace the entire nipple, and not just the red piece and o-ring (as discussed in other posts). I'm...
  6. 9-5 Workshop
    Hi all, I've read the "Brake Booster 101" post here and the procedure in the WIS, but I'm spun out on whether I have to mess with the ABS and ESP systems. The Booster 101 post I think was written for a 9-5 without ESP if I understand it correctly. The WIS says to remove the ABS unit, and...
  7. 9-5 Workshop
    I've got a 2002 9-5 Aero wagon. It's got a series of vacuum hoses for the brake booster that attach using hard plastic nipples with red plastic clips that hold the lines in. The red plastic clips get brittle with age and fail. The line coming off the vacuum pump popped out when I was doing...
  8. 99 & 90 Workshop
    Hi folks. I have a sweet Topaz 4-door 1976 SAAB 99 GL. Outside the main engine compartment, on the back of the wheel well on the driver's side (USA), there is a device with two hoses coming and going, and an electrical contact. Two of the hoses are 7/32 vacuum hoses. They go through the engine...
  9. 9-3 Sedan, Cabrio '04+, Combi, 9-3X Workshop
    I am recent owner of a beautiful convertible blk on blk and would love to make this car the best it can be, buttt lets just say Im not the most saavy. I could use the additional help it could take in removing the top permanently. Or until I have moneys to fix the broken side brace. I heard...
  10. 9-3 Sedan, Cabrio '04+, Combi, 9-3X Workshop
    So I've gone through the forum here, found that brake booster vacuum loss is common. I go to my regular mechanic (I just bought this car, he used to work on my Grand Cherokee) and he said he doesn't touch Saabs. (Only works on the easy stuff I guess). He recommends another shop. They want to...
  11. 9-5 Workshop
    Hi. Before I go for the problem, I want to ask a question. Does SAAB 9-5 with AT brake pedal must be as soft as with manual? Because my father was saying that my brake pedal was very hard (that was before my problem). So, I have a SAAB 9-5 MY2000 with AT. A few days back I lost my braking...
  12. NG900 & OG9-3 Workshop
    Hello, I recently ordered a new brake booster for my 2000 Saab 9-3 (Base, VIN code H). The one I received looks nothing like the one that was on my car. The one I bought is a Centric 160.88084 I cannot find good photos to confirm that the part in the box is actually 160.88084 A picture of...
  13. 9-3 Sedan, Cabrio '04+, Combi, 9-3X Workshop
    Hi All, Like many of you I have been having ongoing issues related to braking performance with my 9-3 Aero V6. After doing a bunch of diagnostics I was able to isolate the cause of my vacuum leak in the brake booster circuit and the answer is not good...the booster itself is leaking vacuum...
  14. NG900 & OG9-3 Workshop
    Hi all, I am going to be doing a revamp on the braking system soon, and I would like to buy the components. I have run into a part availability issue. It seems nobody stocks the vacuum hose that runs from the throttle body to brake boaster for the 2000 with manual transmission. I have found...
  15. 9-5 Workshop
    So a little backstory here: Purchased a 2002 9-5 Aero wagon about 2 months ago and it has tuned out to be quite a fixer-upper. Right off the bat I replaced a cracked fuel tank and also had the head gasket done by my indy mechanic that I have been taking my SAABs to for years. Since then the car...
  16. NG900 & OG9-3 Workshop
    After going through and replacing all the vacuum hoses on my 2000 9-3, I have come to the Brake Booster Vacuum hose, and I have a quick question This is what EEuro Parts has for the correct hose for my car - it feels like a rip off to get this - $240.00...
  17. NG900 & OG9-3 Workshop
    I recently returned from a vacation and haven't driven my 1997 Saab 900SE in a while. After starting the car, I realized that the brake pedal stuck in the down position without returning on its own. I went and got it checked out and the mechanic (not a Saab mechanic, mind you) said that there...
  18. NG900 & OG9-3 Workshop
    Hello SaabCentral, I am a new member and I need help diagnosing a problem with my Saab. My 2000 Saab 9-3 2.0 turbo has a big problem I cannot figure out. The brake pedal is stiff when I push down on the pedal and I can hear a hissing noise. I thought it should be a bad booster, but then I...
  19. NG900 & OG9-3 Workshop
    when braking I get a hissing noise that can be heard inside the car better than under the hood, also more brake pedal pressure is required to stop. I've removed the kick panel under the dashboard and if i hold my hand in front of the brake pedal rod access on the fire wall and press the brake...
  20. 9-5 Workshop
    Hi guys, The brake booster (a.ka. servo) on the 9-5 MY 2000-2001 is prone to leak at some point. As it is not serviceable in or out of the car, if it leaks it has to be replaced. With some borrowed knowledge, I was able to change mine in a more straightforward manner than I saw written up on...
