I have owned 4 Volvos, including my current 850 wagon and S70, and have never had a problem like I am now with the breaks on my 850 waggon. I had a break job done a year ago while living in TX. I moved to PA this summer. While driving the car from TX to PA I noticed the breaks going very soft. I had the car in to a shop to have it inspected and have them look at my breaks. They said the breaks look fine but I had air in my break lines and bled the air out. That fixed it for about 10 miles. I took the car back in had the break lines pressure checked and found air in the lines but no leaks. Then had the break lines bled again and that fixed it for about 10 miles. I took it to a Volvo mechanic and he said there were metal filings and air in the break fluid lines and replaced my master cylinder to the tune of $600+. They claim they test drove the car for 20 miles and I then drove the car for about 20 more miles. The breaks were fine but now the breaks are soft again. I suspect I have air in the lines again. At no time have I had any drops of break fluid under the car. Any one else experience any thing like this or have any idea what it may be?
Thanks,
Peter
