Locate your caliper and follow the lines coming off of it.
Front: Left hand caliper, the line runs from the caliper to a T fitting. One line goes to the right brake caliper, the other runs up into the engine compartment to the master cylinder. Back breaks run from the master cylinder, T off and run down the left hand side of the frame. Then one goes to the left rear break and one runs down the read axle to the right rear brake.
Your local auto parts store can sell you brake lines of various length and diameter at a small cost, it is the labor to replace them that will add up.
Check your brake power booster
You have air in your brake lines. Have the brakes bled.
You will need to use the universal brake lines sold at auto stores. You can check at a Chrysler dealer but I think they are discontinued there.
change the wheel cylinders or the brake lines
With fuel line quick release tools available from your local auto parts store.
Sounds like the brake system needs bleeding. There may be air in the brake lines the brakes have been blead by a ford dealer twice
Open the bleeder valve on the 1990 F150 wheel that needs a line replaced. When the fluid stops flowing, loosen the line connections and remove the line. Install the new line, and bleed the brake lines after the reservoir has been refilled.
Before repairing the brake lines the brake fluid must be drained. The car should be safely lifted and supported. With the wheels off unbolt the line from the caliper to the hardline. Replace the line.
Should be passenger kick panel, if not look up behind the brake pedal on the fire wall.
