I was on way out of town when I got your reply and couldn't follow up as I also didn't have car at home.
Just got home and a.) I am answering your questions and providing results of the test you requested.to be performed.
1. How did brake feel before it went to floor. ? Soft ! But brakes never actually went
to floor, but felt like it was about to go to floor.
2.. Master Cylinder was not empty when I first took car to shop.
3. Vehicle has ABS (anti brake lock system ).
4. Brake Test:
a. Started engine in Park position.
Pushed brake pedal down and it went to about 2" above floor from
height of 6" above floor.
Pumped brake pedal 2-3 times and pedal came up to a higher position,
kept pressure on pedal and it settled to about 3" ABOVE FLOOR
KEPT PRESSURE ON PEDAL AND IT HELD AT 2.5" OFF THE FLOOR
B I repeated Brake test above a couple more times and got the same result.
Pardon the late response.
Look forward to your reply.
