The most common bleeding procedure is to bleed the ABS brake furthest from the master cylinder first, then bleed the other brake that shares the same hydraulic circuit (which may be the other rear brake on a rear-wheel drive car, or the opposite front brake on a front-wheel drive car or minivan). After these have been bled, you then bleed the other brake circuit starting with the furthest brake from the master cylinder.
Air can be very difficult to remove from an ABS modulator assembly because of all the nooks and crannies inside the unit. The modulator may have eight to 10, or more, ABS/traction control solenoid
valves, plus various check valves and dead-end ports. Some ABS modulators have special bleed screws to help you vent the trapped air when bleeding the system. Others do not and require the use of a scan tool to cycle the ABS solenoids while you bleed the system. 1. To bleed the isolation valves in the modulator, there are two bleeder screws. Start with the one toward the engine. Turn the ignition on and apply light pressure on the brake pedal. Open the bleeder screw and allow the fluid to flow until clear. Close the screw and do the same at the second bleeder screw. 2. Depressurize the accumulator by pumping the pedal 40 times with the key off. Wait about two minutes for the brake fluid to de-aerate, then refill the fluid reservoir with DOT 3 brake fluid. 3. Now you can bleed the boost section. This is done by applying moderate pressure on the brake pedal and turning the ignition on for three seconds, then off. Repeat this a total of 10 times. Make sure the pedal feels firm when you have finished, and give the car a road test to make sure the brakes are working properly.
SOURCE: It's a 98 Taurus, Wagon, the brake fluid line leaks
common problem, youll need a flare kit. and some brak line,unions, find a good spot of line in frt, and cut , remove other end at hose, then flair frt, make line the size you need install and bleed system, then check for leaks good luck,

The brake pads and shoes are not elec., your abs light is on because your abs computer pick up a bad signal from one of your abs sensor's,, take it to any auto parts or some one like autozone where they can do a code reading and get back us with the code so we can help you diag. your trouble code.

try bleeding them more,start with the right rear,then left rear,then right front ,then left front, always bleed the brake that is furthest from the master cylinder, sometimes you have to bleed them several times until you get a steady stream of brake fluid.
