How to bleed hydraulic slave/master cylinder on 1989chevy s10 pickup?

Not absolutely certain, but on most, you remove and plug the hydraulic line, unbolt the cylinder, replace it with the new unit, hook up the hydraulic line, top up fluid in the master and bleed the air out. With that said, some of the later models have a hydraulic throw out bearing which takes the place of a slave cylinder. In order to replace one of those it is necessary to remove the transmission to access the unit.

Check the hydraulic clutch operation. This is a clutch master cylinder with a reservoir on the firewall, and a clutch slave cylinder down on the bell housing of the transmission, with a steel tube running from the master to the slave cylinder. When clutch pedal is depressed, hydraulic fluid (brake fluid) is forced from the master to the slave. The slave cylinder should push out a little plunger that contacts the clutch fork lever-pushing it forward to engage the clutch.
Add brake fluid to the reservoir if needed. Watch the plunger on the slave cylinder: if it moves little, or not enough, try bleeding the slave from the bleeder valve. They are bled just like brakes. If bleeding doesn't help, your clutch master or the slave may need replacing. The master cylinder, like a brake master, has internal seals that hold hydraulic pressure, so force can be applied to the plunger on the slave cylinder.

If you need to bleed the clutch, you should notice a soft clutch pedal getting firmer when you pump it (the air that you need to bleed out of the system compresses as you pump, and the pedal gets firmer, just like brakes).

A hydraulic system for a clutch (or your brakes) has a master cylinder component and a slave cylinder component. If you compress fluid in the master cylinder, it exerts force on a (more than one for your brakes) slave cylinder that causes a mechanical component to move.

Recommend you lean into the engine compartment on the drive side at the firewall or crawl under the car and have someone depress and release your clutch a few times. You should be able to find the master cylinder because the mechanical clutch linkage has to be attached to it. The same at the bellhousing, where the slave cylinder has to mechanically cause the throwout bearing to be moved. It is possible (but not probable) that your clutch master cylinder is located on the inside of the firewall, not the outside.

this symptom would typically be solved with a new cluth slave cylinder. Check to make sure the fluid is full in the master cylinder reservoir. If the fluid is empty then there is either a leak, or the clutch is has worn. filling the reservoir and bleeding the system may get you back on the road.

your truck has a hydraulic clutch, which has a master cylinder next to the brake master cylinder. Check the fluid level. If it is low or empty, you have a leak in the master or slave cylinder (at the transmission).
Replace the leaking part and bleed the system to restore clutch pedal.

Your S10 has a clutch master cylinder and slave cylinder, a hydraulic clutch system.

You need to fill the master cylinder and bleed both the master and slave cylinders in order for the clutch mechanism to work properly.

If you are leaking fluid from the clutch master cylinder then you have air in the system. You could try and bleed the air out of the clutch slave cylinder to get the gears but it would not last. The only way is to replace the defective master cylinder, replace all of the fluid and bleed out the air through the slave cylinder.

To determine which type of clutch you have, servo hydraulic or cable.
Look down past the engine bell housing and determine the existance of a hydraulic clutch slave cylinder.(a piece of casting with a rod facing towards the rear of the vehicle pocket into a bracket protruding out of the gearbox bell housing. As well as a pipe and bleed nipple to be crude)
(which I believe you have).The hydraulic fluid for this unit is sourced from the brake master cylinder reservoir via a sneaky pipe partially obscured to the clutch master cylinder on the internal firewall.If you have no clutch slave cylinder near the bell housing there would be an obvious bounden cable running from the firewall down to the outer of which will be stopped at a bracket hanging off the engine.The inner will continue to a bracket protruding from the gearbox bell housing.

i have a ktm 125 wich all ktms have hydraulic cluthcs and i have the same problem as all these fellas even when im riding it just sucks right down all the fluid reply to me on [email protected] ok thanks fellas
