Phillip Posted February 5, 2005 Share Posted February 5, 2005 I have a 1987 subaru GL-10 and recently my PHV (Pressure hold valve) has begun to leak on me. I discovered this on a weekend so i have not had a chance to call subaru to see if i have to sell my kidneys to get the part. does anyone know if there is a rebuild kit or a way to bypass this system and still have the brakes function properly. If not does anyone have an idea what it will put me out for. Link to comment Share on other sites More sharing options...
Skip Posted February 5, 2005 Share Posted February 5, 2005 Phillip, By chance are you referring to the check valve in the large vacuum line to the power brake booster? Link to comment Share on other sites More sharing options...
Phillip Posted February 5, 2005 Author Share Posted February 5, 2005 no, not that it is the whole cylender, at the top of it when i took the seal off i could see an abundance of brake fluid. my car has been using brake fluid at an alarming rate for a while now and after i cleaned it up it began leaking agian. i will post a website with the part(except for being off a 2003).http://websearch.cs.com/cs/boomframe.jsp?query=%22pressure+hold+valve%22+subaru&page=1&offset=0&result_url=redir%3Fsrc%3Dwebsearch%26requestId%3D880650274f639a35%26clickedItemRank%3D1%26userQuery%3D%2522pressure%2Bhold%2Bvalve%2522%2Bsubaru%26clickedItemURN%3Dhttp%253A%252F%252Fwww.drive.subaru.com%252FSpr03_HillHolder.htm%26invocationType%3D-%26fromPage%3DCSResults%26amp%3BampTest%3D1&remove_url=http%3A%2F%2Fwww.drive.subaru.com%2FSpr03_HillHolder.htm Thank you for you help Link to comment Share on other sites More sharing options...
Skip Posted February 5, 2005 Share Posted February 5, 2005 This item as the web site show is commonly called a "hill holder" If you look above the "camshaft" in this shot you will see an 0 ring. This is the part that normally causes the leak. Do you have the facilities to replace it? If not you could probably find one on the market place I guy, Scrapdaddytatum, is tearing down a GL-10 right now that should have one. Hope this helps Link to comment Share on other sites More sharing options...
Phillip Posted February 6, 2005 Author Share Posted February 6, 2005 Thanks for the quick response Skip. It was my son who posted the question. We picked up a used hill holder at a wrecking yard for $12 and he's back in business. Thanks again.
