Alright guys I didn’t buy the hand vacuum bleeder, I just went back out today with my water bottle with a hose.
I started by cracking the bleeder and observing what happened, I waited until I got a little stream of brake fluid coming into the hose but not enough that air would be able to get back in. I went into the Tahoe and pumped the brakes a few times and did this until the hose was full of fluid without air bubbles, then I tighten the bleeder and did the same on all 4 corners.
After that I took it for a drive and it wasn’t right still.
I decided to do the same thing but had my daughter help me with the brake pedal, somewhere along the way I realized that when I was telling her to “hold the brake” she wasn’t actually holding the brake and I went and felt the brake pedal and it just went to the floor…
So I caught my kid up to speed on what we are supposed to be doing and told her she needs to hold that brake pedal down until I tell her she can let go.
We pumped a crap ton of air out of the lines, and then I ran out of fresh brake fluid so I went to get a new bottle.
I came back and it was pretty hot out so I told my kid to go in the house, I continued to bleed the brakes myself with my Tahoe running, cracking the bleeder just barely, and using a broom stick to push the brake pedal while I laid on the ground so that I could watch what was happening with the bleeder hose and if there was air still.
Finally my pedal was solid! But I had a stabilitrak light with a “service brake system” message??!!
I cycled the motor a couple times and the message went away and now my brakes feel better than ever.
