I believe the pan drain and the torque convertor is a 6mm hex bit. I use one that fits on my socket wrench. Craftsman has them. been a while since I drained one, so one of the big guys will straighten me out if Iam wrong on the size .

6 sounds right... but they are the same size, so if you do the pan first, you'll know.

Ok, I was close. I threw a dart at the wall, and it landed on the 6 .

Iam changing everything to manual, so from now on it`s a 14mm .

Where are you? Are you dealing with corrosion? PB anything under there before attempting removal (without squirting it on the brakes).

That is going to be a PITA if not impossible. Tiny bolt, tiny hole, tapered threads, etc... Is there anything left sticking out?

I would probably take the caliper off the car and get it in a vice and go from there.... Very careful drilling can get it out of there. But, try extracting it first.

Small vise grips can often get enough hold to back out what is left of the bleeder after a good soaking with PB.

Barring that even a sharp pair of side cutters or even wire cutters will grab enough to remove the left over piece.

As was said... if those dont work, its time for a screw extractor.

I am in florida and new to the mechanic stuff. The car sat for a while, not sure how long, the rotors and calipers have rust on them but the rotor surface looks good, has a little bit of grooves, when u run your finger over the rotors you can feel a small wave/groove in the rotor, not sure how bad that is??the car was driven to my location.
I have read lots of posts and did try the PB stuff, guess I was just too hard on the bleeder, gonna try again tomorrow, looks like some creatures have crawled up in there and made themselves right at home, all kinds of webs and cocoons! Was hoping I could just bleed the brakes and be done w/ it. The brake pedal is real hard and from what I have read it looks like it could have crud or rust in the lines so was hoping....even went and got the vacuum pump thing so I would not have to have help bleeding
I wanted to change the fluid out and put in synthetic, not sure what is in there, is there any special thing that I need to do to flush between the 2 types of fluids? I really dont know what is in there. But the reservoir looks crusty, should I try to replace w/ the same stuff that is already in there? Or is it a good idea to use the synthetic?
thanks for the help!!

A hard brake pedal is either a large vacuum leak, or a bad brake booster.

Your rotors sound like they have normal wear on them. I would use non-synthetic brake fluid, O-Reilly's still sells non-synthetic brake fluid. I have heard of synthetic BF causing old seals to leak.

Is the booster rebuildable? Guess I will be back at the tool store to get an extracter!

I don't believe the booster is, check for large vacuum leaks first.
