Customer Question

***** *****, trying to find the location of. The rabs valve. On a 97 ford f-150
JA: Thanks. Can you give me any more details about your issue?
Customer: Brake pedal will go down almost to the floor, but they will stop the truck. Worked security at a mechanic expo today and they say it is my rabs valve

is the abs light on? how did you diagnose? any leaks?
Customer: replied 1 year ago.
No the light is not on, adjusted rear brakes checked wheel cylinders no leaks, new pads on back, no air in lines. I have had this problem since I bought the truck new. After brake jobs, a few days later the pedal will start going down to about 3" before the floor

that sounds more like a master cylinder fade.... is the master original?
Customer: replied 1 year ago.
I have tried two master cyl's just to make sure. I want to test the rabs valve, but I can't find it
