Default Clutch Problems-88FS Blazer

OK before we started was difficult to get into gear with the clutch only being 2 months old.Replaced the slave with a new one,still no pedal.Replaced the hydrolic line and a master cylinder rebuild kit,still no pedal.At this point the pedal releases only 1/2 inch from the floor.Next we installed a brand new clutch and had the flywheel machined,so now everything is new.Bleed the system again,absolutly no air but still no pedal,truck moves when pedal is only 1/2 in. from floor.This has got us beat ,any ideas.

I have drove myself crazy with these. so if I remember right you have to unbolt the slave and bleed it from the bottom up. if you let the slave extend while someone pours in fluid on top you will suck down any air thats in the system. after it its done extending itself then open the bleeder and let the bubbles out. DO NOT PUMP THE PEDAL!!! then you need to push the slave cylinder back in so as not to loose the charge of fluid you just got. when you compress the slave some fluid will over flow from the masters resivoir but thats ok. once installed top off and close the cap. then test your pedal to see if it worked. I have had to remove these from the truck and bench bleed to make work. when you buy them at the dealer they come assembled and pre bled.

You might also want to check and see how far the flywheel can be turned. Some can only be cut very little before needing a shim behind the flywheel to compensate for the amount taken off the flywheel. Have you tried a mightyvac to bleed the clutch with.

Dude what are you smoke'n?

when you cut a fly wheel you take the material off the face on the clutch side. if you remove to much then the disc touchs the flywheel bolts and the disc doesn't work. it bends the disc and it blows apart. Secondly there is no such thing and flywheel shims!

the only thing you got right is that you can use a vacuum bleeder but it only holds 3 oz.s of fluid. it would take about 2 seconds and the resivoir would be sucked dry.

i had this problem with my 90 take the whole assembly off line slave and master bleed it as one unit with the slave up in the air master at the lowest point done a couple this way since also if it is the same setup as mine which i think it is go get a ford linkage kit local parts store will have it has a threaded rod and a piece looks like a bullet put the bullet piece on the end of your slave and you will get a pedal thats what i did with mine works great if you cant find it let me know i will get you a part number try bleeding it first watch for very small leaks around the fittings

OK took everything out conected as one unit-reservior,master cyl,hyd line, slave cyl.Did the bench bleed and re-installed without disconnecting anything and still no pedal.Then went back underneath and unbolted the slave to rebleed again.This time my son could not push down the pedal and when it finnally went down the push rod bent.Were going to set it on fire.

Yeah kinda thinking it was not sitting right because after that i could move the fork further into the bellhousing.Straightened it out and tried again but we are right back to the beginning again with no pedal pressure.

these things can be a pain there is no adjustment on the slave use the piece i was talking about it just slip on the end of the rod on the slave if it is bled good you will get a pedal looks like a bullet is actually for a ford dodge also used these it comes with a threaded rod but you wont need that just the bullet shaped piece slide it right on your slave and go here is a link to the part might solve your problem for around 5 bucks https://www.dormanproducts.com/cgi-b...ist=1378:166:0
