Subaru Outback/Legacy Brakes



  • paisanpaisan Posts: 21,181
    I'm pretty much a brake guru for subies, having done 1000s of brakes and race my subaru regularly. Slotted or drilled are a waste of money.

    Mountain Rotors if you can find them are great quality. For pads I really like the Hawk HPs pads on the street. Also make sure to flush your brakes every 2 years.

  • I'm looking at a 2000 Legacy Wagon and the brakes feel pretty soft. The dealer is telling me that this is normal for this model, does that make sense?

    No, I don't think it is. Can you more fully describe the experience that resulted in the decision of "pretty soft?"

  • Thank you for replying. I drove the car and the brake pedal just feels really soft. They are saying that that is a characteristic of a 2000 Legacy. It stopped fine and didn't get substantially stiffer if I pumped the brake, so it seems possible, but I've never heard that before. My frame of reference is a Volvo XC90 and a 2007 Civic, so I'm wondering if I just got used to a newer, higher pedal. They've agreed to turn the rotors and bleed them, hopefully that helps.

    Yeah, I have to say that I never felt my Subaru brake pedals felt "soft" at all, at least not compared to any other make/model I have driven (and that is quite a few!). My guess is that the lines need to be bled or the pads are very low. Even if the pads were low, though, that might result in more pedal travel, but once the brakes connect, the pedal should feel firm.

    You might test it on a gravel road to try locking up the brakes (engaging the ABS), just to see how the whole system behaves.

    The original brake fluid on this car may never have been replaced, and at that age, it is certainly due.

  • I have a 2000 Legacy Outback wagon and definitely have noticed the brakes feel very soft or spongy compared to my previous 92 Subi legacy wagon. It was incredibly noticeable at first, to the point of being concerned I would not be able to stop in time if i needed to. I even had my mechanic check them out. He did find a substantial amount of rust on the rotors which were causing some noise, however he didn't think that would cause them to feel spongy. Maybe this is normal for this model...

    I believe they use a dual-stage brake booster, which allows for smoother stops (as opposed to sudden, jerky stops) but does cause some people to complain about a spongy feel.

    Have them bled to make sure there is no air in the lines, and you should be fine.

    Brakes should be fully flushed every 2-3 years.

  • My year 2000 Legacy AWD had a bit of a brake moment this morning, light snow fall on the local roads and when I hit the brakes all they did was whistle at me which was most un-nerving. There are no indications that the ABS is faulty, and when I tried them out on a downward slope a bit further along the road all seemed fine and dandy.

    Has anyone else had any similar problems? I have browsed the web and have come across ice related abs problems but nothing conclusive.

  • xwesxxwesx Fairbanks, AlaskaPosts: 11,226
    Were there *any* other symptoms? No differences with pedal feel, etc? Did the brakes pulsate at all, indicating that ABS engaged?

    What were the temperatures at the time? Far colder than normal?

    I wonder, perhaps, if old brake fluid is the culprit here....

  • Yes the pedal feel was different, usually the brakes are quite 'spongy' unless the ABS is active, this morning however when this incident occurred there was a really solid feel to them, and no the ABS didn't kick in.

    The ABS had been working as it had activated when I slowed up turning out of our road on a slight down slope in the snow and the ABS also activated moments afterwards when I tested them on a snow covered downhill slope, also checked again numerous time this evening.

    The temperature this morning was actually slightly warmer than it has been for the last few days, around freezing, the outside temperature gauge on the Subaru said 0 C.

    This car is a new one for me, only about 2 months old, so I don't know the state of any of it's fluids, when I've got some spare cash I'll propbably take it to a Subaru dealer for a complete service.
  • xwesxxwesx Fairbanks, AlaskaPosts: 11,226
    Yes, I would gauge by your description of a "really solid feel" that it is likely a problem with your fluid being old (probably original). Brake fluid is hydroscopic, meaning that it likes to imbibe water, so old fluid will have a higher water content than new. If it has enough water in it, ice can form in the lines, and ice in the right place can cause a line blockage. I experienced this many times on my '96 Outback, but replacing the fluid cleared up the problem immediately. The only problem was finding a place warm enough to change it.... :D

    Usually, I found that if I let off the brakes, tapped the pedal a few times, then pressed real hard again, it would let loose and go back to normal operation. Quite disconcerting when it happened though. The hand brake comes in... handy... during those moments.

  • Excellent, as you say just need to find somewhere warm, or give it to a man who has somewhere warm to do it!
  • Have an 05 Legacy GT. Car shaking on braking. Dealer cut rotors under warranty. Happens again 3K miles later. Dealer recuts. Happens again. Dealer replaces under warranty. Now less than 20K miles later, guess what. Happening again. Is it possible that I have some other problem that is causing the rotors to have issues? Any thoughts appreciated.
  • ateixeiraateixeira Posts: 72,587
    I thought rotors could only be resurfaced once.

    I'd just replace them at this point, they're probably too thin anyway.
  • xwesxxwesx Fairbanks, AlaskaPosts: 11,226
    It may have as much to do with braking habits as with the rotors themselves.

    However, given the recurrence of the warp, I expect the stock rotors are insufficient for your application. I agree with AJ - you should consider replacing the rotors with something aftermarket that can handle the added heat.

    I am pretty sure my wife's 2005 Legacy 2.5i Limited Wagon needs new brakes. The pedal is shuddering pretty good when she hits the brakes; does the same for me so it's not just her driving. What I don't know is if she only needs new pads or whether she might also need new rotors too. She has almost 50,000 miles on the car, and still original pads/rotors. With the stop-and-go Austin driving I think they're just wearing out faster.

    Question - my research online shows that this car has 293.5 mm rotors in the front and 289.7mm in the rear. Looks like you can get 255mm rear discs also, but I think the larger ones also fit.are these the right size rotors? My understanding when we got the car was that the Limited model wagon got a bit bigger rotors than the standard 2.5i model. But now I can't find that piece of info anywhere.

    Thanks -

    I would measure them to be sure.

    If the rotors are bigger than most likely the mounting brackets would be different. I doubt they'd be interchangeable.

    Going to change the Brake Fluid. Is this the way to go with it?

    Bleed each brake cylinder starting with front right, rear left, front left, rear right. Keeping main reservoir topped up and keep bleeding till new fluid comes out of nipple.

    Is that it?
  • I am having the same problem with my 99 Legacy GT, 100k. But it doesn't take a steep grade. A moderate grade will cause it, as will simple deceleration. ( I know when it's supposed to downshift and when it's not, and this is not normal.) I haven't tried to fix it yet because it hasn't been a big issue. Thanks.
