Any advice on how to properly bleed clutch? I'm at a loss at what do to next. Any advice or help greatly appreciated? I'm trying to imagine, if there's a way to remove clutch cover, remove slave get it horizontal and fill that part?

Anyone have experience, after removing this style of slave? Sting32Jul 9, at PM. You do the bleeding exactly like I normally do. But just for knowledge and fun, bleed it like this.

I have to take a tiny amount of grease to hold the throwout bearing and washer in place when putting the cover back on. Mine's a TRS but parts look basically the same in most reguards let us know what you find. ADV Sponsors. Dirty bikeJul 9, at PM. Clutch bleed with new lines or parts can be a pain. I used to get a bubble right down at the bottom of the line before it went to the slave that just wouldn't come out with any amount of bleeding, tapping, reverse bleeding, etc.

Tying down the lever works. Use a zip tie or bungee cord, what ever works for you. Give it a good 12 hours before you check it again. Hope that helps! Joined: Oct 1, Oddometer: 11, Location: nm. Sting was close.If your car's clutch is not releasing fully the clutch master cylinder needs to have air bled out of it.

You will need a helper to depress the clutch in the car at stages of this operation. Be sure to have extra brake fluid on hand to top up the master cylinder afterward. Follow the steps outlined below to bleed a clutch master cylinder. The clutch slave cylinder is usually below and to the right of the master cylinder.

Find the bleeder valve, a small bolt that is used to discharge air pressure buildup. Have your assistant step down firmly on the clutch pedal inside the vehicle, holding it down to the floor. Using a wrench, loosen the bleeder valve on the slave cylinder till hydraulic fluid comes out. Have a container handy to catch the fluid.

A bubble of air will come out first, followed by a spurt of fluid. Tighten the bleeder valve again, and tell your assistant to release pressure on the clutch pedal slowly till it is in its normal rest position. Check the master cylinder to ensure it still has ample fluid. If it drains out and air enters the clutch slave cylinder or clutch hose, you will need to perform the air bleed operation a few more times.

Check for any leakage from the cylinders or the clutch hose. If these parts have pinhole leaks, you will need to replace them. Repeat the air-bleeding cycle again, with your assistant pressing the clutch pedal down all the way.

Loosen the bleeder valve again and check for more air escaping. Continue to repeat the bleed cycle until only brake fluid drips out of the bleeder valve. Tighten the bleeder valve for the final time, tell your helper to let off the clutch, and open up the top of the master cylinder to add hydraulic brake fluid till it is topped up. Do not overfill the clutch master cylinder. Clean up your workspace of all tools and fluid containers.

Wipe off any brake fluid that is on the paintwork and chrome trim, as it can damage painted and chrome surfaces. Clean off your tools of all brake fluid and gunk they may have on them, and put them away.

Start the vehicle and use the clutch to engage the forward gears. The pedal should feel firm as you press it down, and the gears should change smoothly without slipping or grinding. Test the reverse gear as well for correct engagement. We welcome your comments and suggestions.

To ensure our content is always up-to-date with current information, best practices, and professional advice, articles are routinely reviewed by industry experts with years of hands-on experience.

What You'll Need. Vehicle owner's manual. An assistant. Socket wrenches. Brake fluid, 1 liter.A clutch master cylinder contains a reservoir with brake fluid. It is connected to the clutch slave cylinder through hoses.

When you push the clutch pedal, brake fluid flows from the clutch master cylinder to the slave cylinder, applying the pressure necessary to move engage the clutch and this in turn changes the gears on your manual transmission. A hydraulic clutch system offers greater ease and comfort while pressing the clutch pedal to change gears than opposed to a cable activated system. Most hydraulic clutch systems have their own dedicated master cylinder; however, some vehicles use one master cylinder for both the brake system and the clutch system.

Any time you open the hydraulic system you will need to bleed it to remove air pockets. Air pockets prevent the hydraulic system from functioning properly. You may need to bleed the slave cylinder as part of routine maintenance procedures, such as replacing vehicle fluids or because you need to replace the slave cylinder. For the remainder of this article, we will assume that the hydraulic clutch system has its own dedicated master cylinder.

Use the following steps to locate the slave cylinder and open the bleeder valve. Here is how to bleed a clutch slave cylinder:. Locate the brake master cylinder - Open the hood and locate the brake master cylinder on the driver's side of the vehicle, close to the firewall.

Tip : If you are performing routine maintenancebegin by opening the cover to the master cylinder reservoir and use a turkey baster to suck out the old brake fluid before replacing first and then replace it with fresh fluid. Fill the clutch master cylinder - Check your owner's manual to find the brake fluid specific to your vehicle.

Pour the fluid into the clutch master cylinder. Locate the slave cylinder - On most vehicles, it will be bolted externally on the transmission. In others the slave cylinder is inside the transmission but the bleeding valve can be easily accessed on the outside.

The quickest way to locate the slave cylinder is to follow the hydraulic line from the clutch master cylinder. Verify the location of the bleeding valve or bleed nipple - In some situations, it may be necessary to use a floor jack and safety jack stands to lift off the ground and secure it in order to gain access to the slave cylinder. Open the bleeder valve - Use a line wrench to open the bleeder valve to the slave cylinder. Place a drain pan under the slave cylinder to catch the brake fluid.

Bleed the brake fluid - Leave the bleeder open and allow gravity to bleed the slave cylinder for one to three minutes. Warning : While gravity bleeding, keep an eye on the brake fluid level in the master cylinder. It is important to prevent the brake fluid from becoming too low as it will cause air to be sucked back into the system.

Tip : You can use your line wrench and tap on the slave cylinder to move any more air pockets that may be trapped inside.

Attach tubing to the bleeder nipple - Close the bleeder valve on the slave cylinder and attach a piece of aquarium tubing to the bleeder nipple. Place the other end in an empty water bottle and top off the master cylinder with brake fluid. Pump the clutch pedal - If you have a friend with you, have them get in the driver's seat and pump the clutch pedal 10 to 15 times to build pressure.

Then have them press and hold the clutch pedal completely down. Test the bleeder - While the clutch pedal is held to the floor, use your line wrench and open the bleeder. Observe the air bubbles and brake fluid exiting the slave cylinder. When the flow of brake fluid stops, close the bleeder and have your helper release the clutch pedal.

Repeat steps as needed - Repeat steps 4 and 5 until only the brake fluid comes out of the bleeder on the slave cylinder. Warning : Never release the clutch pedal with the bleeder valve open. Doing so will suck air into the system.There are three methods used by auto manufacturers to actuate the clutch diaphragm in manual transmission vehicles: push rod, cable, and hydraulic.

Adjusting push rod and cable-type linkages is fairly simple, but hydraulic clutches require bleeding when installing a new hydraulic throwout bearing. There are two types of hydraulic clutch actuators: the ram type and the bearing-type. This system is a hybrid of a push-rod mechanism, where it uses a typical mechanical clutch fork and throwout bearing to operate the clutch diaphragm.

The push rod linkage is replaced with a hydraulic system, where the pedal operates a master cylinder which drives a slave cylinder mounted outside the bellhousing. The slave cylinder or ram, moves the clutch fork, operating the clutch engagement. Most modern vehicles have gone to the fully-integrated hydraulic system, which eliminates the mechanical fork and bearing and replaces it with a hydraulic throwout bearing. When the clutch master cylinder pressurizes the fluid in the lines, the bearing ram expands, pushing on the clutch diaphragm, disengaging the clutch.

This is a hydraulic bearing. Most of these units have two lines- one goes to the master cylinder, the other is the bleed line. The bearing rides on a stub that goes around the input shaft of the transmission.

This hydraulic bearing, from a Dodge Challenger, is a self-bleeding unit. When replacing it or if the master goes dry, you simply pump the pedal to bleed it. Bleeding the clutch is a little different from bleeding brakes. The main difference is that there is only point where the fluid is utilized, so air is less likely to be trapped in a T-fitting or caliper. Because of this, the process is very simple and can be handled by one person. Start off with plenty of fluid in the reservoir.

Always start with the reservoir topped off. You will lose some fluid during this process, keep an eye on the level. Locate the bleed port on the ram or the line coming off the hydraulic bearing. If you are working with a bearing, you will need two wrenches, one to hold the line and one to open the bleeder.

The bleed line is often hanging loose, so you need two wrenches, one to hold the fitting and one to operate the bleeder. Crack the bleeder open and let it drip. Because the fluid is above the master cylinder and the lowest point in the system is the bleeder, it should push all of the air out of the lines and out of the ram or bearing. Close the bleeder screw, and top off the reservoir. Just let it drip. This is called gravity bleeding. It can take a while, but most of the air will come out naturally.

Now you can check the clutch pedal.Got car issues? Well, we've got the answers!

The clutch system in your vehicle most likely works very similarly to your brake system. In most cases, it may even use brake fluid as its working fluid.

If you drive a classic car or truck you may have a mechanical clutch meaning it operates by a system of levers, pivot points and connecting rods to translate the movement of the clutch pedal into movement of your clutch pressure plate releasing the clutch.

New cars use hydraulic clutch systems because they are much simpler to install, take up less space and do not require adjustment as your clutch wears down. If you have replaced the clutch slave or master cylinder, the lines, or simply changed the fluid, you need to do an adequate job removing the air from the system before your clutch will work properly.

As you press the clutch pedal, the master cylinder forces hydraulic fluid, in this case brake fluid, down through the line into the slave cylinder. The pressure of this fluid will cause the slave cylinder to activate, pushing your clutch fork and disengaging your clutch.

If there is air in the system, that air bubble can compress. This compressing air bubble will absorb much of the fluid being sent from the master cylinder to the slave cylinder keeping the slave cylinder from actuating as far as it should, or even at all. If the slave cylinder does not travel as far as it should, your clutch will not fully disengage making it difficult to shift your transmission, especially into 1 st gear from a stop.

To remove the air from your clutch system you need to push or pull the air down through the fluid line to the bleeder valve on the slave cylinder. To keep things clean you should attach a tube to the nipple on the bleeder valve. If you use a clear tube it can be easy to see when all the air has exited the system.October 31, References.

Learn more The slave cylinder is part of the hydraulic clutch system in vehicles with manual transmissions.

When the master cylinder or the slave cylinder starts leaking fluid, it must be replaced along with the fluid. Adding the new parts introduces air into the system, which creates a soft or non-existent clutch action when you press the pedal. To bleed air from the hydraulic clutch system, you must release air from the slave cylinder.
