I just got a new to me 2010 2.3 manual 2wd ranger. I bought it knowing of a clutch issue, no further details. Upon receiving it, I realized the clutch hydraulics were in need of bleeding - if not eventually replacing the slave.

I took off the master and bench bleed it and then gravity bleed the slave. It's all working for the time being.

What I don't know is, how do I fill the clutch master cylinder properly? There's a rubber insert in the reservoir that I haven't had on any other car. It hangs deep into the reservoir and has no holes in it. Do I remove it then fill the reservoir, or do I put fluid on-top of the rubber insert?

Thanks

 

You remove the rubber "air block" add fluid then put it back in, don't overfill

The rubber piece is there so less air touches the fluid, the fluid absorbs moisture in the air, it is not needed for operation, just there to limit fluids air contact

Master brake cylinder is the same, should have a rubber seal in the cap for the same reason, and also why you want to keep brake master full, so less contact with the air

 

So no fluid should be in between the rubber insert and cap correct?

Thanks again

 

Yes, correct
