You are bleed the system from a valve similar to what you find on a brake system, located at the slave cylinder on the bellhousing.However, just like your brakes, the system is not supposed to loose fluid, therefore you need to find the leak and correct it or you will be right back where you started in a couple of hours or days. check master, fluid line and slave for leaks. Good luck with it.

    Just a note on that...if you can't find the bleed valve, then it hasn't been bled before. You will find a small fitting in the slave with an allen key opening. You need to replace it with a bleed valve.

I have a 2003 Ford Focus lx and the clutch pedal has no resistance on it and it will not go into gear. Please help I need this car to get to work

Check the clutch fluid level. It will be a small reservoir close to the brake master cylinder. If the clutch reservoir is empty, add fluid.( brake fluid ) You may have to perform a bleed procedure at the clutch slave cylinder attached to the transmission Pump the clutch pedal several times and have someone open the bleeder screw until fluid comes out and the clutch pedal has its resistance back

Need help bleeding clutch on my 05 v-rod

As the clutch wears the fluid level in the reservoir will rise so the initial fluid level should not exceed the FILL LEVEL. And the motorcycle must be upright and the handlebars set to level the fluid in the clutch reservoir.

When filling an empty clutch fluid line, a VACUUM BRAKE BLEEDER with a fitting that mates to the secondary clutch actuator bleeder screw threads can be used to draw the fluid down the clutch line and the air out of the system.

Take off the clutch fluid reservoir cover and then initially loosen the banjo bolt just enough to allow air bubbles to escape. Be careful because clutch fluid under pressure can squirt a steady stream a long way.

Hold the reservoir cover in place and pump the clutch hand lever 5 times or so and then hold the clutch hand lever against the handlebar and with a shop towel under the fitting loosen the banjo bolt and watch fro air bubbles to be released and then retighten the banjo fitting and only after it is tight release the hand lever. Check and refill the reservoir with fluid to the FILL LEVEL line and repeat the previous step three or more times and until only a steady flow of clutch fluid without air bubbles escapes from the banjo fitting at all times keeping the clutch fluid level in the reservoir at the FILL LEVEL with motorcycle in an upright position.

THEN remove the secondary clutch actuator cover, cover the exhaust pipe(s) with towels and place a suitable pan under the right side case to catch excess clutch fluid THEN while holding the reservoir cover in place pump the clutch hand lever 5 or more times, then hold the clutch hand lever against the handlebar and loosen the secondary clutch actuator bleed screw and watch the bleed screw for air bubbles. When the hand lever touches the hand grip hold it there without releasing it until the bleed screw has been tightened again and then release the hand lever., refill the fluid reservoir to the FILL LINE and repeat the previous steps, always keeping the fluid reservoir full of fluid, until a steady stream of fluid with no air bubbles coming from the bleed screw. When there is no more air coming out leave the bleeder screw tight and fill the reservoir with fluid to the FILL LINE.AUTION

THEN test pressure by squeezing clutch hand lever repeatedly does not build pressure in the hand lever and the fluid level does not remain at the FILL LINE then there is a leak somewhere and it will have to be located and fixed. If there is no visible leak check the secondary clutch actuator boot for leakage.

When there is no evidence of leakage and the clutch lever works properly and the fluid in the reservoir is at the FILL LINE install the reservoir cap and insert and tighten the fasteners to 0.7-0.9 Nm (6-8 in-lbs); the reservoir banjo bolt to 23-31 Nm (17-23 ft-lbs); the bleed screw to 9-11 Nm (80-100 in-lbs); the secondary clutch actuator cover fasteners to 6-10 Nm (53-88 in-lbs) and then test ride the motorcycle.

If the clutch does not have correct pressure you may have a dragging clutch and/or hard shifting.

Bike has been sitting up for a year or two. I squeezed the front brake lever, which was really tight. It broke free but now there is no pressure at all. Not sure where to start.

Open your brake reservoir and check fluid level. Add fluid to proper level and slowly squeeze the lever, watching for bubbles or fluid flow in the reservoir. Check the brake calipers to ensure there is not a leak in that area. If no leaks, continue squeezing the brake until it is fully operational. May have to add fluid while doing this. Close reservoir.

My clutch reservoir is empty of fluid. I believe there is air in the lines, how do I bleed the line and where is the nipple to do the bleeding?

okay..I replied to your other post on the bleeder...but anyway...right behind the base of your left rear cylinder is a square rubber flap...lift the flap and the flap is teethered to the bleeder nipple.

Okay....add fluid to aware dripped brake fluid will destroy paint, fairing plastic have a pail of warm sudsy water to cleanoff any spilled fluid ASAP.

Replace lid ....attach a hose to bleeder nipple to a waste container. Pump the lever slowly a few times.....then pull lever partway in, and crack open the bleeder.....slowly pull lever in and hold...close bleeder. release lever. Pump lever ....hold partially in...crack bleeder....pull in , close bleeder, release bleeder.
Add fluid as needed to reservoir.
Never release lever with bleeder open or you will draw air back into bleeder from hose...always close bleeder first.
Continue this till clear new bubble free fluid exits the bleeder.
Refill reservoir leaving some room for expansion as the fluid heats up. Reinstall cap.

Aside from an obvious line leak....main cause of fluid loss from clutch reservoir is the slave cylinder seals are weeping....should consider rebuilding or replacing the slave...about $70 for a new slave.

Clutch wont work after sitting all winter. Shop says to take off reservoir top, straighten the bike so reservoir is straight, pump the clutch handle a few time and it should work. No luck so far

You probably need to bleed the sytem. Might as well start with fresh fluid.
Get a syringe without the needle, draw the old fluid from reservoir.....then refill with new fluid from a new container (brake fluid absorbs moisture from the air). Sit the diaphram back on the reservoir so that as you pump lever...fluid doesn't squirt over the side...brake fluid will destroy paint and fairing plastic if not cleaned immediately with warm sudsy water...always have a pail handy when handling brake fluid.
Find the bleeder bolt on your clutch slave.....on Yamaha its under a rubber flap on left side...Suzuki might be different). Attach a hose to bleeder and route to a waste container.Pump the lever a few times and while holding lever partially in...crack bleeder and squeeze lever to force the old fluid out....close bleeder, release lever....repeat the bleeding until new clear bubble free fluid is exiting. Monitor the reservoir level as you push out the old fluid and replenish as needed...if you run it will be fighting to rid the air out for some time.
You want the reservoir level to be about 60% full so it can expand with engine heat, before reinstalling the lid when done.

I noticed my clutch resovoir appears to be very low, if not empty. n reading the owner's manual, it states the fluid will "rise" as the clutch wears. Should I be able to see any fluid in the resovoir? What...

Do NOT add brake fluid to the clutch reservoir. The BMW clutch uses mineral hydraulic fluid which will not mix with brake fluid.

If your fluid is dropping, the chances are good that the slave cylinder is leaking. If not attended to soon, it will eventually contaminate the clutch, which will then also need to be replaced.

The clutch on my 1995 suziki vs 800 slips under power,it disengages

Keep the bike upright and place the handlebars straight. Check the clutch fluid level in the reservoir. If it's below the lower mark, take the cap off and fill it to the upper level. Use D.O.T. 3 or 4 brake fluid. If this doesn't solve the problem you may have air bubbles in the line or dirty fluid. If so, make sure the reservoir is at the top level and replace the cap and tighten it back up. Remove the secondary gear cover.(just ahead of the driveshaft) Attach a pipe or hose to the bleeder valve and run the other end into a pan or something similiar so you don't get fluid everywhere.Squeeze and release the clutch lever several times in rapid succession, and squeeze the lever fully without releasing it.Loosen the bleeder valve by turninmg it a quarter of a turn so that the fluid runs into the resepticle; this will remove the tension of the clutch lever causing it to touch the handlebar grip. Then,close the valve,pump and squeeze the lever, and open the valve again. Do this as many times as needed to get the air out of the system and nothing but clear brake fluid running through the line You may have to add fluid to the reservoir during this process. When the air bubbles are gone and the fluid is running clear, top off the reservoir to the upper level. Also, you may know that brake fluid will peel the paint off of your paint job so be careful not to get any on the painted surfaces.
If all of this fails, then you probably need new clutches but most likely not. I have an '86 model (same bike) and it still has the original clutches. Hope this helps; John

Check the fluid level in the reservoir for the slave cylinder, or look underneath to find a leak. If the reservoir is empty then you need to replace the clutch slave cylinder. A quick fix is also try to bleed the clutch slave like you would bleed brakes, open the bleeeder push the pedal down and hold it until the bleeder is closed, repeat until solid fluid comes out...will take 2 people.
