correlation between bleeding brakes and brake booster leak V70-XC70

Just had a shop bleed my brakes, now I have a leaking sound at the brake pedal when I release it.
From what I can find out it seems to be a problem with the brake booser.

Question is, could the brake booster be damaged during the bleeding procedure.

Thanks.

    "Question is, could the brake booster be damaged during the bleeding procedure."

    Probably not if it's done correctly but there is some special Volvo gizmo that's required to bleed the brakes correctly. Without the tool, my indy non-Volvo shop refused to do the procedure.

      Have you any clue what that gizmo is? V70-XC70

      re: "...there is some special Volvo gizmo that's required to bleed the brakes correctly...."

      Do you have any idea what that gizmo is? I'm thinking of buying an XC, and I like to do all of my brake work myself (I've owned a 164 and many 240's for over 30 years and have worked on their brakes all that time) -- so I'm wondering what novelty and/or hassle I'm in for if I get an XC and can't do it "my way".
      Thanks.

        Not talking about the 7mm hex tool are you for caliper loosening? As far as bleeding the brakes are concerned, I've never had an issue and never needed a special tool. I have heard of a hose that connects to the bleeing nipple that has a ball/check valve in it to keep air out of the system, but I've never found I've needed such a device. The best thing is a "power bleeder" that looks like a big pump you hook up. www.fcpgroton.com sells these as does several other vendors.
        If you do a search on swedespeed.com you'll see a guy made a device that is hooked up to a motorized airpump (normally used to inflate tires) that hooks up to his cigarette lighter that does basically the same thing.

        Here is an eBay item that may be the "gizmo." http://cgi.ebay.com/New-Brake-Bleeding-Kit-all-Saab-Volvo-Skoda-Volkswagen_W0QQitemZ4616457666QQcategoryZ10432QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

          I agree that the PowerBleeder is the best thing yet! I've been using it now for about 3 years, as soon as it started being sold by IPD, and it's a pleasure compared to all the gadgets I've used over the past 30 years, from my '73 164 through a half dozen or so 240s!

          But what I was asking for was about something unknown to me that "Bill the Cat" mentioned -- his message is the one just before my earlier one, and he wrote in it, "...there is some special Volvo gizmo that's required to bleed the brakes correctly. Without the tool, my indy non-Volvo shop refused to do the procedure....", and that piqued my curiousity. I'm as surprised about it as you seem to be -- I'm hoping that Bill the Cat comes back with an answer.

            This was the advice of my local ASE shop (5 minutes away vs. 20 minutes for my Volvo indy and 20 for the dealer) that works on our normal cars. He said he called the dealer to get the procedure and that's what they told him.

            The other thing I recall is that he said that he could bleed the 850 brakes without any problem, this was something new. Something about avoiding excessive pressure when doing the flush. So I took it to the dealer, they bled the brakes and a caliper froze about 2 months later. Probably a coincidence. My indy Volvo shop has done all subsequent brake bleeding, and the other front caliper froze after they worked on the brakes.

            I remember reading something about this here (or on one of the other Volvo boards - unfortunately I don't remember where!)

              I recently replaced my master brake cylinder on my 1998 S70 and used a Mini-vac which I bought from Harbor Freight to bleed the brakes. Everything worked well for me. The Haynes service manual for the S70 did not discuss any special equipment needed.
