Any idea on what might be the problem with my hydraulic clutch system (and what/how to fix)?
-Loosing about a 1/2 quart of clutch/brake fluid a week.
-Can't find any leaks.
-Engine frequently stalls when sitting at a stop light in gear with clutch pushed all the way to the floor as if I just let up on the clutch while in gear.
-Starting to get a little chatter when releasing the clutch to start and when releasing the clutch while shifting gears.
-Replaced the clutch master cylinder about 6 months ago. had to bleed the line a couple times even after replacing. also, had to clean the fluid reservoir because seemed to be clogged.

Hi,if you are loosing clutch flued the most likely place is the slave cylinder as you have already replaced the master cylinder,its proberly leaking inside so you cant see it.
I mean all you have is one slave cylinder atached to a pipe wich attaches to the slave cylinder so if theres a leak it has to be from one of these parts.
let me know when you find out,all the best.
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

Not sure of the model EX, but it probably has a clutch hydraulic slave and master cylinder that has leaked out the hydraulic fluid. Fill the clutch master cylinder (near the brake master cylinder) with brake fluid and pump the clutch pedal several times. The clutch work again until the fluid leaks out, so the permanent fix is to replace the master and or slave cylinders and bleed the system. Other models have a clutch cable that would need replacing in this case
No, the clutch and brake hydraulic systems are not connected.
If you are loosing fluid, you should be able to tell if it is leaking from the master cylinder where you add fluid, or the slave cylinder on the transmission.
The Clutch Master Cylinder is located on the firewall inside the engine
bay, and usually next to the brake master cylinder as the brake and
clutch pedals are usually very close to one another. The Clutch Master
Cylinder is responsible for transferring the clutch pedal pressure
hydraulically to the slave cylinder to release the clutch. You can tell
when your clutch master cylinder is dying or needs repair when you
depress your clutch pedal and it slowly sinks to the floor and does not
return. Since the entire system is a hydraulic one, the master cylinder
also has a reservoir that holds the fluid used in the clutch hydraulic
system. If you decide to change the clutch master cylinder it is a good
idea to also get a clutch slave cylinder at the same time, as both units
typically fail around the same time. When replacing your master or
slave cylinder, its always a good idea to flush your entire system to
prevent water buildup or air pockets from being present when you are
driving. Also always keep an eye on the fluid in your reservoir, dirty
fluid may mean that the internal seals are allowing dirt and
contaminants into your master cylinder.
It might be the brake & clutch fluid wrong because it is too old inside. First time change the brake & clutch fluid. If the problem persists then replace both clutch master hydraulic cylinder and clutch receiver hydraulic cylinder. Bleed also correctly the clutch hydraulic line!
HYDRAULIC SYSTEM BLEEDING
The clutch hydraulic assembly has been filled with fluid and bled of air at the factory. Do not attempt to bleed the hydraulic system. While the unit does not require periodic checking, it must be serviced, when necessary, as a complete assembly. The system is full when the reservoir is half full.
Only DOT 3 brake fluid should be added to the system. If the fluid level drops, inspect the system, including the slave cylinder, for leakage. A slight wetting of the slave cylinder surface is normal. Fill the clutch master cylinder reservoir with brake fluid. Be careful not to spill brake fluid on the painted surface of the vehicle.
Hydraulic Clutch System BLEEDING
The clutch system can be bled using a pressure bleeder. Follow the instructions that come with the pressure bleeder for the proper pressure bleeding procedure. The maximum line pressure while pressure bleeding must not exceed 36 psi (248 kPa).
NOTE: To bleed a clutch manually requires the assistance of a second person, a section of hose that is compatible with brake fluid (preferably clear) and fits the slave cylinder bleed screw snugly and a container to catch the fluid that is bled through the system. As brake hydraulic fluid easily absorbs moisture, always use fresh fluid when bleeding a hydraulic system.
Before servicing the vehicle, refer to the precautions in the beginning of this section.
To bleed the system perform the following:
Top off the hydraulic fluid reservoir using a fluid that meets the standards of the vehicle's hydraulic system.
Open the clutch slave cylinder bleed screw and press the clutch pedal to the floor and hold the pedal down.
Close the clutch slave cylinder bleed screw.
Release the clutch pedal.
Check the hydraulic fluid level and top off as necessary.
Repeat the above steps until the discharged fluid is clean and no air bubbles appear during the bleeding process.
This is probably a hydraulic clutch. check for fluid at the clutch master cylinder, if empty check for a leak at either master or slave cylinder (on the side of the transmission) if fluid is present in the reservoir try loosing the fitting on the slave and have an assistant pump the pedal while adding fluid ( this is called "bleeding", just like with a brake system). don't allow the master cyl. reservoir to run dry. Hope this helps
