By the way if you ever need.
Abs brakes drop to floor intermittent.
Either that or excessive amounts of air may exist within.
Without any warning i lose my brakes.

This problem has occurred five times in.
The sensors detect wheel speed and will send a message to the abs module to rapidly pump the brakes when it is detected that the vehicle is skidding or has lost traction.
I have had the master cylinder replaced and the brakes flushed and replaced twice.
Pump brake pedal several times with engine off then push down brake pedal very slowly to see if it goes to the floor.

The leak may coming from a brake line or one of the brake calipers on your vehicle.
The brake fluid has a lot to do with controlling the braking pressure within an anti lock braking system.
Sometimes there could be a leak from this reservoir which will cause the fluid levels to drop.
Here s some brake service history that may also be relevant.
When the abs system is not functioning then loss of traction skidding and hydroplaning are far more likely to occur under heavy braking conditions.
