Is there a problem with the ABS unit on a Mazda?
This is a Mazda and Ford problem. You do not have air that just appeared in the system, this is a ABS actuator fault allowing pressure to bleed past the valves in the actuator. The fault has been known to go away at times when reactivating the abs on gravel or icy roads. If it does not go away you need to replace the very expensive abs unit.
What happens if you don’t isolate the brake pedal?
If the ABS unit activates but does NOT isolate the brake pedal, the brake fluid will flow directly into the the accumulator, a spring-loaded brake fluid container for ABS systems. This lets the pedal sink to the floor. If the brake pedal sinks to the floor only when the ABS unit activates, then your isolation valves may be the problem.
