I have a problem with a soft brake pedal. The pedal goes 1/2 way to the floor before engaging - it did not do this before the last brake job. I replaced the Rf caliper, pads and rotors both sides. Bled the front bleeders and had a soft pedal. I then bled the rear lines in sequence and bled the anti lock brake bleeders. Getting fluid out of all bleeders. Still have a soft pedal. What can I do next?
If I have to replace the antilock assy can I replace it with a standard brake master cylinder from a salvage yard?
Do you

SPONGY OR SOFT BRAKE PEDAL Means there is air in the brake system either as a result of improper bleeding, fluid loss or a very low fluid level. The cure is to bleed the brakes using the sequence recommended for the specific vehicle. Another possible cause is a rubber brake hose that is "ballooning" when the brakes are applied.
