Another clutch bleeding tale
#1

My recent posting reported that I sometimes felt my clutch pedal tap my foot after release. I was experiencing no real trouble and just completed a trouble free 400 mile romp. However, I was three years out from my last brake fluid change, so I decided to start with the clutch slave cyclinder. I used my Mighty Vac, which had successfully drawn the old fluid from both the brakes and separate clutch hydraulic systems on my '62 Jag Mark II. I used a baster to remove all of the brake fluid, refilled the reservoir with new fluid, and jacked up the car on the driver's side. I found a 7 mm wrench fit the clutch bleeder, attached the Might Vac connector to the bleeder, pressurized it, cracked open the bleeder and began drawing out fluid. I hadn't removed the starter to perform this job, and also failed to release the clip that holds the wiring running next to the bleeder, so I had touble closing the bleeder rapidly. Sure enough, I found the clutch pedal had dropped to the floor.

At age 70 (almost 71), I'm not anxious to do much real mechanical work. My goal now is restore enough clutch function to allow me to drive the car to a repair shop. It doesn't seem feasible to attach a line to the slave cylinder with the tubing immersed in a container of brake fluid, since I suspect pumping the pedal, holding it down, etc., the usual bleeding system, won't work. I'm considering elevating the rear of the car--something recommended here and elsewhere and ignored by the writer--and trying again with the Might Vac. Or I may just have the car lifted and hauled a long way to the shop. Cost wise not an attractive alternative. Suggestions!

Do you have someone that can pump the pedal for you? If so just have them pump the pedal and hold it, crack the bleeder, close the bleeder and release the pedal, then repeat a few times. It is also best to have the rear end up in the air, you can get to the bleeder with the front on the ground and the rear up.

do yourself a favor and save yourself a ton of misery - throw away the mity-vac - buy a motive - vacuum bleeders do not work well, for obvious design reasons

I 2nd that early and often...



Motive bleeder works very well on this job, and it's is very smart to "recruit" a "volunteer" to pump that pedal. Before the Motive, I must tried for hours with my dad, jacking, elevating, working the pedal. Futility, and no reasonable explanation.... <img src="/forum/images/smilies/968/mad.gif" class="smilie" alt="" /> But after the Motive, I moved fluid through with no problem and bled it just fine. (I also added the RS Barn stainless steel braided clutch cable while I was under there and the clutch feels more solid than ever.) I highly recommend it because if you have not changed out that old clutch hose, it's one of those things that is going to go, and it's not about if, but when. Murphy's Law will have it happen at 5pm in Midtown Manhattan at the mouth of the Lincoln Tunnel - or something like that. <img src="/forum/images/smilies/968/huh.gif" class="smilie" alt="" />



Best of luck!

lol - true enough - here's murphy's law for you - dan was down here - he picked up a line i had sent here for him while he was here - we ran out of time, and did not install it - he figured he would do it when he got home in the bay area, 400 miles away



45 minutes from here.......................

yup, and a miracle things worked out as well as they did. even though those guys spent an hour manually bleeding the system the clutch was acting up all the way home..had a mind of its own. had it power bled the day after I got home and worked like a charm ! definitely power bleed the damn thing !!
