    Hello!

    I hate that my first post is a help request, but here goes.

    I have a 2009 Tacoma. I changed out the brake pads on my front breaks over the weekend. The passenger side went just fine but I've now got a brake fluid leak on the driver side.
    The actual brake pad change went fine but when I was cleaning up I found a small rubber washer on the ground that I hadn't noticed while changing either side. I found it on the driver side so it's pretty clear that's what's causing the leak but I'm not sure exactly where it goes. I've been searching the internet for a diagram but haven't found anything yet. I don't want to take the wheel off until I know exactly where the rubber washer goes.
    Can anyone point me in the right direction?

    TIA!

    Did it look like one of these?

    @98tacoma27

    Thank you! that's exactly what I was looking for. The washers in the second row is what it looks like. From the diagram it looks like a piston seal but I'm not sure that's right.
    I did split the caliper apart while changing the pads.

    Thanks!!

    Next time, there is no need to split the caliper unless you are actually changing those seals. It prevents moments like this. :p Plus you won't have to bleed them.

    I know it's not the recommended way of doing things but it seemed simpler at the time :)
    I'm still not 100% about where the washer goes but at least I've got something to reference now.

    Thanks

    You'll see where it goes when you split the caliper again. It will be plain as day.

    You were right, the second I pulled the caliper apart I saw where it was supposed to go.

    Thanks again!

    Similar problem here...my brother was working on my truck...accidently split the caliper...quickly tightened it and eventually bled the brakes...a couple of weeks later I realized the problem and found a rubber o-ring that fit real tight and so far no leak

    Toyota parts department said it looks like an o-ring on their computer but wasn't sure and the only way to purchase it is as part of a $40 repair kit...Oreilly's sells a similar repair kit for $7...I'm just wondering if the o-ring I bought is similar to the stock part

    My question: Was the original part a copper washer or a rubber o-ring?

    sorry, but this is not accurate for the tacoma. I just rebuilt my calipers using that kit a week ago. it is a square cut "o-ring" that goes between the 2 halves, and there is only 1 per caliper. You could probably get away with just using a normal o-ring of the proper diameter though.

    OP, next time just take the pins out and slide the pads out the top.

    Thank you for your post. We found a normal o-ring that fits snug tight and I'm on day 3 with no leak. I'll keep an eye on it though and I'll probably buy the $7 repair kit from O'Reilly's and throw it in the glove box just in case. Thanks again.
