Manual
WARNING: Brake fluid contains polyglycol ethers and polyglycols. Avoid contact with eyes. Wash hands thoroughly after handling. If brake fluid contacts eyes, flush eyes with running water for 15 minutes. Get medical attention if irritation persists. If taken internally, drink water and induce vomiting. Get medical attention immediately.
CAUTION: Do not allow the brake master cylinder reservoir to run dry during the bleeding operation. Keep the brake master cylinder reservoir filled with the specified brake fluid. Never reuse the brake fluid that has been drained from the hydraulic system.
CAUTION: Brake fluid is harmful to painted and plastic surface's. If brake fluid is spilled onto a painted or plastic surface, immediately wash it with water.
NOTE: When any part of the hydraulic system has been disconnected for repair or installation of new components, air can get into the system and cause spongy brake pedal action. This requires bleeding of the hydraulic system after it has been correctly connected. The hydraulic system can be bled manually or with pressure bleeding equipment.
SOURCE: 04 Focus SVT- All brakes will bleed out except the right rear..??
Have somone help you as you bleed the brakes. Have them pump the pedal 3 times and hold the pedal down with constant pressure while you crack the bleed valve open to the problem caliper. Don't let them release the pedal until you have closed the bleeder valve. Continue this process until you have fluid coming out without air. Periodacillay check the master cylinder to be sure it remains full enough so as not to allow more air in because the resivouir ran to low during the bleeding process. If when you are done and the brake light continues to be on then you will need to bleed the proportioning valve until the system balances out on line pressure.
If this works can you please give me a rating??? Thank you.

Ok the reason I ask is that will help to pinpoint the concern. See ABS system when you first turn the ignition on will do a self test on itself,light turns on for a few seconds then turns off if everything proves out. Then when you start driving once you reach about 12 mph it will activate the pump and perform a 2nd self test.If everything is ok light stays off,if it see's a problem it turns on the light and disables the ABS.
Since yours comes on after you start driving then problem is most likely a wheel speed sensor concern. Since you just did a rear brake job and the problem started after this I would say it is one of the rear sensors.You need to look at the sensors and make sure the sensor and ring look ok and that you didn't get grease or dirt in the teeth of the sensor ring or maybe bent the end of one of the sensors and make the gap larger between sensor and ring.

John, My 99 F150 had an abs light on and I found the right side front wheel sensor wire had fallen off of the inner fender mount and burned the insulation and grounded the wires together, I taped up the wires and tied it up and the light went out. Your ABS module is located directly beneath your air cleaner next to and just above the steering gear box. It is black plastic and silver alumnium. Says Kelsey-Hayes right on and has six brake lines attached to it. As for the rear brake take that drum off again and have someone help by pushing the brake pedal down while the drum is off press lightly and very slowly, verify that the brake cylinder is moving, do not push hard and fast as it will probably blow the pistons out of the cylinder! If is is frozen replace it and bleed and it should be fine. The brake light is probably on for low fluid. Let me know how it goes.
