    Can anyone tell me how to install this pin back in the clutch pedal that attaches to master cylinder? Is there some sort of trick. I just replaced the clutch master and for the life of my I can’t get the pin to go back. I’ve tried dental floss I’ve tried bending a wire.
    Who the hell designs this stuff?
    Thank you in advance.

    Nice tool. Biggest pain in butt to get that pin in. I got pin it and bled system. Now it seems clutch grabs much much higher to the top. Almost all the way. It has a new clutch. Maybe 500 miles on it. Why would clutch grab so late and before I replaced master it grabbed in middle? Had to change master cause pedal would all of a sudden get mushy. No fluid dripping anywhere but it was original master cylinder so I figured internal seals. Can’t get used to clutch grabbing that high

    I think still some air inside the hydraulic system

    Does that also mean that the throw-out bearing mechanism/seals were also cleaned and refreshed?

    There is a turnbuckle and rest position stop adjustment screw -- see TR WSM page E9. Also, is the "empty pedal travel" in spec? (I.e., were the old and new clutch master cylinder identical?)

    You might have to bleed the clutch master cylinder again if what Steve suggested does not work out.

    I don’t know if the old master and new are the same. I bought master that is for this car. When I did clutch I cleaned but didn’t replace slave cylinder. When I changed clutch the pedal was normal. Grabbed in the middle. Now it grabs all the way at top. Like 3in from top of travel. I bled system again I saw no bubbles but I will try it again part number was 175211

    you may try to bleed under pressure. so 1 is pushing 2 or 3 times the clutch inside the car and let the pedal down. the 2. one opens the bleeder at the clutch and when no more fluid comes closes the bleeder srew and then inside let the clutch pedal back. may be you have to put your shoe under the pedal to get it back I´m sure there will come then again some air bubbles. you may do this min. 7 times. if still some bubbles then repeat until no bubbles anymore.

    That seems like the part is/was initially correct and OK, but something has changed somewhere. Wonder if it is something weird like a blockage in a flexible line is not allowing the pressure to release (like a flexible brake line causing a brake caliper to "stick" on) -- just a thought...

    Did you mistype here? "3in from the top" would be below the mid-travel point of the clutch pedal stroke?

    Does the downstroke of the pedal seem normal (e.g. expected force thru stroke)? Do you have some small amount of "empty pedal travel" at the top?

    Very little pedal travel before stop point. Clutch pedal is firm and feels just like before pressure wise. Maybe the seals were going for a while and caused clutch to catch lower in travel until it let loose completely. Shifts are smooth just might be needing to get used to in would even say three inches. Maybe less travel. It grabs about 3/4 to7/8 of travel
