Clutch pedal no pressure, brand new master cylinder
Hey guys, new to the forums so sorry if noob. Anyway so was trying to bleed my clutch on my 05 Z, and I guess my friend disconnected the banjo bolt right next to the bleeder bolt instead. So we connected it back and bled it. But the clutch pedal had ZERO pressure ( stays stuck on the floor). So I thought maybe there's air in the line. So I kept bleeding it for a long time and nothing changed.
Then I figured maybe my master cylinder's seals just messed up. So I bought a new one. Then bled it again, and nothing changed. The only thing that I can think of is the slave. But wouldn't it be leaking if it was bad?
Help my car is screwed. Thanks

I think so? Pumping the pedal 5 times, holding it on the fifth pump, then crack open the bleeder to let some of the brake fluid out, close it. Then repeat right?

So you think it just takes more time? Cause I feel like I was bleeding it for forever. Haha there's no other problem it could be? I'll try bleeding it longer today

So that's basically adjusting the bolt on the cylinder to change the travel of the piston to what the fsm says right?
It can't be any other problems right? Some other threads say could be the slave but I think it would leak right?

Try taking the MC out and doing what they call "bench bleeding" first to get fluid in the MC.
I had the same problem, I replaced with new MC and no pedal. I took out the MC and bench bleed it and BAM. I have so much pedal now I had to order the RJM Performance clutch pedal to help out with the extremely tight pedal.

I am not even supposed to be here to today...
I will try and help. Helps to have 2 people so you can walk away when you get mad.
Ok pull the MC out the car with the reservoir still attached. pull the line off the slave cylinder on the trans.Put MC in a vice, put the line that was going to the slave cylinder into the MC reservoir while still hooked up to the MC. put fluid in the res and pump the rod/plunger all the way a couple times you should here see/here it work(fluid level drop in reservior). Then with help from a buddy very carfully put the MC back in while trying to keep as much fluid in the MC as you can. Some will come out so don't worry just don't swing it around.
By doing this your pushing the MC plunger/piston all the back which you will never be able to do with just air. you need pressure and the fluid creates pressure.
Hope that helps you.

Auto mechanics is a game of ruling things out. So go down the line until you find the problem.
Not to sound like an A-hole but are you sure you bench bleed the MC?. Did you hear/see air escape into the MC reservoir? you need to get all the air out of the MC. like 3-6-10 pumps. The fluid in the reservoir should almost all drain into the MC once you give it a couple of pumps.
I did the same thing and once hooked up it took 1 minute to get pedal so if your at it for 30 you didn't do it right.
Your clutch master should have 1 line/hose going to the reservoir and 1 line going to the slave cylinder on the trans. Take the line off the slave and put it in to the MC reservoir. Fill the reservoir put MC in a vice and pump/push in the rod on the MC.
If your talking about the banjo going to the slave cylinder on trans, If no fluid is coming out/going to the slave. then you didn't bleed the clutch mater cylinder.
If you did do the bleed right and fluid is coming out/going to the slave and still no pedal. then you have a bad slave cylinder. You can also bench bleed the slave cylinder. But if all you did was take off the line on the slave cylinder, fluid should still be in the plunger/piston area on the slave.
I believe you still have air in your system and you need to get it out.
