How do you change brake master cylinder on 1988 ford ranger?

Answer 1

This isn't a difficult job to do. The first thing is to prepare. Purchase the masterclinder first. Most will come with a brake bleeding hose assembly. It should have two plastic fittings with a length of hose. Screw the fittings in the right holes where the brakes hoses will be. Attach the hoses to the fittings. Place the mastercylinder in a vise or stabilize it somehow. Pour brake fluid into it. Place the ends of the hose's into the mastercylinder with the brake fluid. The ends need to stay under the fluid level. Use a screwdriver or something like it and pump the mastercylinder in the end. It will be stiff. As you pump it gently, air bubbles will come out of the hose ends. Keep the mastercylinder full. keep pumping until there are no more air bubbles coming out. Leave it in your vise. remove the old mastercylinder by removing the two brake lines (metal) and any wires. Remove the two nuts that attach the mastercylinder to the truck. Place the new mastercylinder on the studs and tighten the nuts. Remove the plastic fittings and hoses. Install the brake lines. If your pedal is spongy, have someone pump the brake pedal until it's hard and hold it. Loosen the brake bleeder fitting on the wheel farthest from the mastercylinder (rear, right). Fluid will come out. Keep holding the pedal down until you have tightened the bleeder screw. Repeat this several times remembering the make sure the mastercylinder doesn't run out of brake fluid. Do the same thing on the other side several times. Move to the front brakes and do it again, both sides. This will remove any air trapped in the lines and remove the old brake fluid that might corrode your system. Be sure to clean and drain the old mastercylinder and return it for your core charge if there is one. Good luck.
