I have a mleod adjustable MC. the car was fine 3 days ago. now I have this problem. is it possible that the master cylinder needs to be adjusted. I already checked fluid level, it was fine. thanks guys Jim

I would adjust the rod on the MC so that it engages right about even with the brake pedal or to wherever you like it, but that's a good starting point. If it starts acting up after that or goes back to engaging funny you probably will have to rebleed which hopefully you did after you put in the new MC.

The adjuster nut is inside the vehicle. Look at your clutch pedal under the dash and you can see a rod connecting to it. There will be a nut on the end with a eyelet on the end, loosen the nut and adjust it in or out by just screwing in or out. To bleed it you will need a friend to help you. One underneath the car and one working the clutch. If you look at the transmission you can see a steel braided line coming into it. Just above it will be a whole with the bleeder valve inside of it. Use a 7/16" socket on a 1/4 drive ratchet to open and close it while you bleed it.

Unfortunately, this is something that happens with the McLeod sometimes. When I first installed mine, I adjusted it where it needed to be. I had the car up on jack stands, and put it in gear and pressed the clutch in to make sure it fully dis-engaged. Everything seemed great! Took her for a spin, and it was awesome!
Now fast forward to a few days later. I get in the car, and push the clutch in, and there is excess free play before the master began to actually move fluid. I was confused. I pumped up the "free play" by pressing it in ONLY the amount that was "loose", which wasnt pushing it all the way to the floor, only a few inches max. This solved the problem, and it did this every once in a while.
I contacted McLeod, and talked to Fred. He had never heard of such, and was mind boggled by it. He said to send it back if I couldn't get it figured out. Well that was over a yr ago, and I can't remember the last time I had that occur.
I would try doing what I just said, see what happens, and go from there. Now I know this shouldnt happen at all, but, it's better than nothing. Maybe try calling McLeod and see what the say about it now. I'm sure more cases like this have happened since mine. Ask for Fred, he was very nice.

So you loosen the nut, and twist the rod itself to screw in or out?
My pedal has a lot of excess play before engaging (depending on the temperature of the car). Cold = Lots of play Warm = a little bit of play

I bled the MC 2 days ago. and drove the car that night everything was fine. then I wen too drive it today and I had the same problem... does the MC just need to be adjusted?

It's possible. Where is the clutch pedal in relation to the brake pedal? I understand it should be just forward (toward the driver) relative to the brake. If it's not, you should adjust the rod end on the master outwards towards the driver.

ok I spoke to mcleod and they told me to use a mighty-vac to bleed the MC. I have done that and I am still having this problem. I drove the car yesterday and it was ok at first, then it went back to having about 1in. of play before it would start to disengage and continued to get worse the more I pressed it in . and have a sloppy feel . I pressed the pedal down the amount it was loose and it would tighten up as if there was nothing wrong. so Im asking for your opinions,experiences anything will help. thanks

I know that's bullshit, but it's all I could figure out, and they weren't any help in solving the issue. At least they were nice when I talked to them...

I thought about it more. And realized that it started happening when it the weather started getting colder. Im not sure if you noticed it when the weather started getting colder or not. if anyone else has any input please add... thanks
