Changed MC & Brake Booster--Now No Pedal

[modernsportscar]

As stated--had a brake booster issue in wife's 2008 CX-9 (AWD GT). 117k miles--bought 5k miles ago from original owner. No known maintenance history.

Replaced both booster and master cylinder (just to be sure). Thought I bench bled MC, but apparently did not do a good job. Bled all four corners--driver rear had quite a bit of air. Now I have *maybe* an inch of brake pedal travel--that is, goes all the way down to an inch from the floor. I'm getting nothing but fluid every time I bleed. Gone through almost a quart of fluid so far trying to bleed.

Is there something obvious I might be missing?

Thanks in advance for any help.

You might have to bleed the abs to get it right and for that a scan tool is need to activate the abs while bleeding is done.

Thanks, I'll look into that.

Yes, the ABS module usually holds a bit of air.
