Hi,
Thought I had a no brainer. Had a brake pedal (99 Mazda 626) going to the floor so I put a new master cylinder on.
It did not help at all. The pedal still goes to the floor with no resistance. Usually with a bad MC you can stomp on the pedal and get some pressure on the pedal. But that was not the case with the new MC. I've bought bought bad ones before so I thought maybe I got a bad rebuild. (bought from Napa)
The brakes still stop the car pretty decent, but the pedal is on the floor.
The plumbing is a little strange on this car, so wasn't sure if something else is going on. There are 3 lines coming from the MC (no ABS). The line on the bottom of the MC goes to the LF brake. The other 2 lines go to a valve on the firewall where it is distributed to the remaining wheels.
I bled the MC on the car, but didn't have time to bleed the wheels. But something tells me, it is not going to help. Maybe I'm wrong.
Any advice ?
thanks

After having the master cylinder off you should bleed all the wheels too.
Bleed the entire system real good then see if you still have the problem.
Start with the wheel farthest away from the MC (right rear, left rear, right front,left front).
