Brake pedal going to floor?

[Mother]

Man do not get it I Installed new pads from europe with ceramic in them forget the name but after 25 miles or so they seem spongy and go almost to the floor so I reblead and retest same thing. Well took wheels off again and there is allot of black buildup looks like dust so I cleaned rotors (did not remove pads) installed new fluid (Gold) and rebled brakes with no leaks noticed and they pump up but when I drive they are still soft and want to go to floor. The fluid level never drops. I am rebleeding using the brake pedal with assistant which always worked on my other cars. At a loss anyone?

Are you using a pressure bleeder or the pedal?

You are bleeding both fittings on each wheel?

Another possibility is that the master cylinder is leaking back (or other leak).

Thanks Loren,

Pedal pressure old fashion (open valve on down pedal and closed on pedal up then pump up and redo) with assistant pumping brake and clear bottle and clear bleed line. Bleeding both first outside then inside valves per wheel. Would I see bubbles in master cylinder fill resvoir if I was leaking back in master cyl? I could have gotten the pads dirty or slightly oiley during cleaning and installation could this cause the pedal to go down? When my master cyl went out on other cars if I was holding the brake down I could feel the pedal leak to the foor but in this case it just seems to go along way down before any braking action occurs.

Sounds like air in the system to me.

Anyone nearby that you can borrow a power bleeder from?

[Mother]

No, not off hand but will try to get a hold of one. thanks

When you replace brake pads there is no need to open the Hydraulic system. If this is the case and you never had issue before then maybe its just coincidence and the Master cylinder is bypassing. If you did open up the hydraulic system then you will need a brake pressure bleeder and a TEXA Scan tool or the factory scan tool to do the Abs bleed Procedure.

Not sure how the brakes where before doing the brake job, when I got the car it was the first thing I did during my inspection, so did not have a chance to drive it. The pads and fluid needed to be replaced. Not sure if my car has ABS, but do not think so, but how can I check.
