2004 E-450 brakes . Because of some serious wear we did a complete rear brake job w/rotors ,calipers,pads on our motor home and bleed properly . Before this we had good pedal , pedal is now soft after initial firm press , thinking some dirt got into master cylinder we changed it and put in all new fluid and we still have SOFT PEDAL , any idea what to look for next ? Diagnosis procedure ? TY

 

Welcome to the site..
If you introduced air into the system, master cylinder, you'll need a capable diagnostic tool to bleed the brakes of trapped air...

 

Thanks 👍
in my searches about the problem I came across the special tool to bleed correctly , is this because front my be abs ?
