How do you bleed the breaks pumping them dont work

Bleeding brake lines requires 2 people. If you are sure your problem is air in the brake lines then you need to bleed the air out. First step is to be sure the brake fluid reservoir is full of fluid. Then crawl under the car starting at the right rear tire. There is a small fitting that is near where the brake line enters the back of the wheel assembly. You will need a wrench to fit this fitting. Have someone in the car to pump the brake pedal three times and the last time hold the pedal down firmly. At that point you will loosen the fitting at the wheel and brake fluid will spray from the fitting. If there is air in the lines, it will make a popping sound when it escapes with the brake fluid. The person in the car should hold the brake pedal down until you tighten the fitting back. If they let up on the pedal before you tighten the fitting it will draw air back into the lines. If no air pops out, you may have to repeat the process several times per wheel. Move to the other rear wheel, repeat then to the right wheel, then the left front wheel. During the bleeding process, be sure to keep the brake fluid reservoir full of brake fluid. Obviously, don't get the fluid into your eyes, mouth or nose. Also it can cause rashes and reddening of the skin so you may want to wear rubber gloves. It will leave an oily stain if you let it flow onto your driveway or garage floor, so keep them covered during bleeding.
