This is a pain job. Wear safety goggles, as you will probably have rust falling down on you as you work. The brake line fittings will be difficult to separate. Soak the fittings with some penetrating oil for several days to make them easier to take apart. Get a pair of vise grips on the fitting that you want to loosen, and another pair where it attaches to the next line. Make sure the line you don't want to change doesn't turn, as it is common for the lines to be fused together with rust, and many times the 'good' line breaks off at the connection, requiring you to replace more lines. Parts stores have different sizes and length brake lines, and they are quite cheap. Bring the old line in for them to match up the fitting size on both ends and the length. You will have to bend them to match the original, just do it slowly so you don't 'kink' them (they are junk if that happens, and you will have to start over). You will then have to bleed the brakes to remove air in the lines. Good luck.

How to reset the proportioning valve in brake master cylinder for 1989 Ford F150?

to reset the proportioning valve try bleeding the master by applying pressure and slowly opening one line at the master until the valve centres. you may have to do the same with the other line to get it to centre, sometimes you have to hit the area where the valve is as it may be stuck to get it to move.

Hi I have a 1989 F150 and none of the brake lights work. I checked the fuse, the brake peddle switch. Oh and the emergency flashers only work in the front.
