I went out to resurrect my old Ford. Started backing out of the driveway and the and the brake pedal hit the floor. Wide eyed I quickly put the car in neutral and engaged the handbrake. Luckily this was done before the downhill slope begins in my driveway. So once I got it back up on level ground I went ahead and added some fluid to the master cylinder and pump the brakes. The the fluid quickly went down the master cylinder into the lines and subsequently on the floor. I found the source of the leak. Which I suspect is common in these cars. If you guess the source of the leak was that little box right above the rear axle you are correct. So I have a couple . X 2 questions. I should mention this is non abs with rear drum brakes. one the manual clearly states that using copper lines is not recommend in this car. This was at the time the manual was printed did they mean copper as in regular copper lines NOT the new copper zinc lines we have today that don't rust? Cuz that's what I plan on buying. Two. the fittings themselves are they the m10 1.0 fittings all around at the wheels and the master cylinder or do I need two sizes. 3 should I try to route them along the original lines removing the old ones; or is there a better way to route out the lines? 4 finally beside some type of tube cutter and a flare what other tools might I need also is this use a single flare or a double flare? thanks in advance for all your help I am completely new to installing brake lines.I never had to do it before cuz I lived California. And honestly I'm just glad this all happened in my driveway rather than coming off the off-ramp of a highway.
