1994 Jeep Wrangler 4cyl - Bleeding slave cylinder

Hi Bruce
I advise you to check the flexible hose first, if its ok, so the problem is the master/slave cylinders.
Good luck

You wont need a photo its super easy, but it is under the jeep follow the line from resivior to the clutch master cylinder (holds fluid) then the other end located on the trannsmission is the slave cylinder the bleeder is on it usually has a rubber cap on it! hope this helps. p.s. dont let the resivoir get empty it will leave air in the system and make bleeding almost impossible.

yes it is inside of the bellhousing of the transmission and does require transmission removal for replacement

leaky slave or master cylinder - if you have someone listen to the slave cylinder while you press the pedal is should "squelch" if there is air in there, if the slave cylinder doesn't make a squelching sound then the master cylinder or a hydraulic line between the two cylinders is leaking - slave cylinder isn't very expensive but the master cylinder can be rather pricey. and any good parts shop or motor-factor can source or make-up a new hydraulic line if it is the line itself that is leaking.

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.

The bleeder valve will be on the slave cylinder. Follow the hydraulic line from the Master Clutch cylinder down to the slave cylinder by the transmission.

If you have an internal slave cylinder check it for leaks or if an external slave cylinder check it for leaks. Check the back side of the master cylinder where it attaches to the firewall and see if the seals are leaking. If so replace the master or rebuild it. Same with the slave cylinder.

U have what is called a hydraulic clutch, one of the hydraulic cylinders hs failed, there is a master and a slave cylinder. The most likely and most common cylinder to fail is the slave cylinder, this requires the transmission to be pulled out to replace it. the art is around $125.00, while the trans is out u might as well replace the clutch, the labor is about the same. Here is a picture of the part, let me know if u can see it.

Try unbolting the slave from the bellhousing, leave the fluid line attached. Bleed the slave, then bolt it back on. Make sure that when you are bleeding it, hold the slave so the bleeder is up.

hello usaully it is on the slave if not try to hold the clutch pedal in overnight with a stick or something take the cover off the master for the slave so air can escape thru the top goodluck
