Hello everyone. I need some major help. I own a 06 Tahoe 5.3 2wd. I just changed my brake booster along with the brake cylinder added brake fluid and bled the brakes 3 times. My brake pedal is still stuck in the floor. I don’t know what else to do. Has anyone else had this similar problem? How did u resolve it?

Thank You.

 

Welcome to the forum. Did you bleed the new master cylinder? If so, then you might have a bad master cylinder.

 

I replaced the master cylinder too. I bled the brakes again. My driver front brake line bleeds really slow let’s some air out and then almost stops dripping as if it has no more pressure.

I had a mechanic bleed the abs module. However my brake pedal is still stuck in the floor and won’t come to place on its own.

any suggestions? Ty.

 

You have air someplace in the system. I'd back bleed it myself. Might be able to rent one at an auto parts store. Make sure to take the M/C cap off or loose, if you do so. And once you do so, get the brake fluid off your paint.

 

What about loosing pressure in the brake line? Does that indicate air too?
