When I applied my brakes they seemed bumpy so I figured they were warped. I was correct and the brake shop turned the rotors they could and replaced the ones they could not and put on new brakes. Everything seemed fine, but soon after the brake job I noticed my brakes pedal seemed soft and traveled almost to the floor when stopping at a light. Took my truck back to the brake shop and the checked it out and said I needed a new master cylinder.

They replace the master cylinder and called me to tell me it was done, but even though the brakes were better they still seemed a bit soft. The shop said they were afraid I needed a new ABS actuator and that if I did it would cost $1,200.00 to replace it. They told me to try the brakes out and let them know what I thought.

Yes, they are better, but still soft and travel after stopping. I could use your advice as I will be honest I know nothing about any of this. Could it be something else? I have never had any trouble with this kind of thing until now.

Thank you for your help,
Jean

A lot of times when this happens the brakes need bleeding due to air in ABS system if a power bleeder cannot take care of it then a scanner has to be used to open valves on the ABS unit. Of course if the shop only does brakes and not much else he is not going to have the correct scanner to open the valves on the ABS. Have them or a shop that can do this for you.
