Brake pedal it goes normal until close to the bottom and then continues about a quarter inch with a clunk at the bottom?

Okay now I think the brakes are working I am able to move them and when somebody puts on the brakes I cannot move them. If I charge up the battery and turn the key do you think the pedal will sink to the floor?

Was everything replaced on the driver's side too? Does it release when you open the bleeder on the caliper? As far as the vehicle running vs not running, you will get power assist and it will be easier to depress, but it shouldn't go to the floor.

Let me know.

Yes everything was replaced on the driver's side. I put the old caliper bracket on the driverside and greased up the caliper pins and everything seems to have worked and the pedal is staying solid so far.

Welcome back Chad,
Open the bleeder on the caliper when the drag is on it and let me know if the drag goes away.

Hi:
In the picture, number 2 is the push rod (brake booster side) and number 1 is the distance. Is that what you needed?

Let me know,

Never mind that last question. Maybe I screwed it all the way back in bled the brakes when I got to to rear driver's side I kept pumping with hose and bottle and a lot of air came out. I don't know if it was getting empty in the reservoir. But I filled it back up. And kept pumping so I move on to the next brake no air bubble came out the drivers front and no air came out.

Okay:
It sounds like the brakes are releasing now. Is that correct? And the numbers listed are tolerance allowances for adjusting the push rod.

Replaced front brake pads, after which the pedal had extreme slack and had to pump to stop. Bled brakes to no avail. So I was going to bleed again but bleeder valve (driver side) wouldn't budge. Went to drive back home to attempt further to loosen it and low and behold I had no brakes at all. I have checked booster, master cylinder, brake lines, proportion valve, ABS module and all seem in fine working order. I bled the brakes again from passenger side and then tried the driver side to realize I'm getting no fluid to driver side. So again checked lines by blowing through both ways with air hose. Still no fluid and no pedal at all.

Good afternoon,

The pressure comes from the master cylinder. Most likely you need that and the caliper that you cannot bleed.

I would start there.

Hello thanks for using 2CarPros.

it seems complete brake system is trapped by air bubbles. you must follow bleeding process by sequence starting from rear right then rear left, front right finally front left. check picture.

Follow our guide:

Please let us know what happens with you.
Thank you.

Okay, so after bleeding repeatedly in sequence (including bleeding master cylinder) we had fluid to all but left (passenger) rear. A friend said to open all and let flow until fluid at all. Done that but still no pedal. Re-bled in sequence but now have nothing to front calipers but steady stream to rear.
