Question about 1991 Ford Aerostar Extended
Its not as hard as you may think. But you will need some one to help you. First make sure you brake fluid resivor is full and then put the cap back on. Your helper needs to be in the vehicle and have them pump the brake pedal 5 or 6 times and then hold the brake pedal down. Now you need to be able to get undeneath the vehicle Im not sure if you have standard brakes in the front or disc brakes but the procedure is the same for both. If its disc brakes look for the half moon caliper mounted to a round steel disc. On the caliper there will be what appears to be a small nut about 1/2 inch in size its round on the top with a hole in the center of it. its usually mounted half way down to the rear of the caliper. While your freind still has pressure on the brake pedal turn that nut using a box wrench and fluid will stream out and the pedal will go to the floor in your vehicle. Close the nut and have your freind pump again 5 or 6 times then open it again, and liquid should come out. As long as liquid comes out with no air your good. Now if you have brake drums proceedure is the same but that bleeder nut is mounted on the wheel cylinder. On the front brakes in most vehicles its usually mounted at the very top or the very bottom backside of your brake drum. It will look the same as my description of the caliper one I just described. And you bleed it the same way. As long as no air is coming out each time you bleed it off your OK and slowly the person pumping the brakes will feel the pedal getting higher and higher and harder and harder. Each time you complete bleeding a wheel check your master cylinder to make sure its always full of brake fluid other wise you will get air back in the system and you will have to start this whole procedure over again. As far as your back brakes Im pretty sure they are standard brakes not disc brakes but again you just need to locate the bleeder screw on the wheel cylinder and bleed it the same way you bled the front brakes. Once you have finished the last wheel your brake pedal should be high and firm. Take a test drive but go slow first to make sure you did get all the air out of the system and the brakes are grabbing good for you.
I hope this helps you out and if it did leave me some feed back....
