!992 GMC - were is the bleeder on the clutch slave cylinder to bleed the clutch ?

There is a bleed valve on the slave cylinder that is on the transmission bell housing. Use an 8 or 10 mm wrench and loosen the valve, then snug it just hand tight. Now have someone depress the clutch pedal. As the pedal is depressed, loosen the bleeder and let air or fluid out. Close the valve as the pedal hits the floor, then repeat until a steady stream of brake fluid comes out of the bleeder as the clutch is depressed.

In many cases, the hydraulic clutch will gravity bleed when the bleeder valve is open. This is especially true if the fluid line from the clutch master cylinder (on the firewall) down to the slave cylinder is not bent up or around any objects, but is pretty much a straight drop down to the slave cylinder. If it won't gravity bleed by just opening the valve, have a helper work the clutch pedal as described. Remember to close the bleeder before letting the pedal up, so that air won't be sucked back in through the bleeder valve.

your clutch master cylinder is right beside your brake master cylinder. I would advise you to replace the master cylinder and the slave cylinder together. The slave cylinder is on the side of the transmission. The slave cylinder does have a bleeder screw on it after the parts are bolted in place fill with dot 3 brake fluid and open the bleeder on the slave cylinder until fluid starts dripping out. Then tighten bleeder then open bleeder and have someone push down on clutch pedal while the pedal is pushed down tighten the bleeder the release pedal. Repeat this procedure until you get no air and the pedal feels normal and you should be good to go. Good luck!

Hi, if you didn't bench-bleed the slave, it can have trapped air away from the bleeder. What I do is to bleed the slave by pushing the cylinder in with the bleeder open (close the bleeder before releasing the piston). Depending on the type of slave, you can usually get a screwdriver between the clutch lever and the piston to compress it. You need to compress it fully to get the bubbles out of the bleeder port. OK?

bleeder valve on slave cylinder at transmission

does the slave cylinder have a bleeder? it should. auto parts stores sell hand-operated vacuum pumps for bleeding brakes. i have used mine to pull fluid through clutch hydraulics to get enough pressure to commence the regular bleeding process. hope this helps.

all clutch slave cylinders have a bleed screw,one pipe in,the other hole is the bleed screw hole,should be tapered at the bottom,for the screw to deal against,also sits above the pipe,to let the air out

1. Fill master cylinder reservoir with DOT 3 brake fluid. Raise and support vehicle. Attach bleeder hose to bleeder screw on bleed line of slave cylinder. See Fig. 1 (attached in link) . Place other end of hose in glass container 1/2 full of brake fluid. Loosen bleeder screw while holding bleeder screw fitting.

2. Have an assistant depress clutch pedal to the floor. Tighten bleeder screw and release clutch pedal. Repeat bleeding procedure until fluid entering container is free of bubbles. DO NOT allow reservoir to run out of fluid during bleeding. Refill clutch master cylinder reservoir.

CAUTION: DO NOT allow bleed line to bend or flex when loosening
bleeder screw.

Drain or bleed? The bleeder nipple is on the slave cylinder. Fill master cylinder,leave the cap loose, open the bleed nipple at the slave cylinder,and let gravity do the rest. whe vo more aie bibbles come out and it drips steady. Close the bleeder, top of the master cylinder and you are done.

you have to bleed the air out of it. If there is not fluid leaking from the master cylinder on the firewall.it can leak on the inside of car or the out side if the master cylinder is bad.first make sure the reservoir stays full then open the bleeder on slave cylinder. this is called gravity bleeding. once fluid comes out, tighten bleeder, pump pedal one time loosen bleeder while holding clutch pedal down and then tighten. do this repeatedly until no air comes out. you can pump pedal several times,then hold and bleed however you like but I have better luck with individual pumps. just make sure that the lines hooked to slave cylinder are tight and there are no air leaks. and that the line does not go below the slave cylinder because sometimes air gets trapped in the lowest part of system.

Try opening bleeder screw on slave cylinder and let it GRAVITY BLEED, just open clutch mater and fill with fluid and then open slave cylinder bleeder screw and let it gravity bleed( run out by itself) When it does close bleeder screw and you should get pressure.(make sure master doesn't run out of fluid during this preocess).If pedal not good enough bleed as usual. PUMP PEDAL ABOUT 6 time then hold down to the floor using wrench open slave bleed screw and close back up with pedal still being held DOWN. Repeat until fluid comes out with out air.However if all this doesn't work, YOU WILL NEED TO REPLACE CLUTCH MATER CYLINDER. Conatct if you need more help and Good Luck. Thanks for using FIX YA
