Good day, My volvo850(1995) failed to pass the annual technical test due to worned break lines. There are visible cracks in the rubber that covers these lines. I've never did break lines replacement before and I think its wise to ask about how to do it before starting doing it. I have the procedure for bleeding the system took it from Haynes repair manual. But, i still lack the step by step instructions for break lines replacement. Anybody knows how to do it? thanks in advance, Husam
