Usually each cylinder is directly in front of its pedal, so the clutch cylinder is the one on the right as you look from the front of the car. The clutch master cylinder is usually found on the bulkhead next to the brake cylinder. , buy one of the same manufacture, and be absolutely sure you get the right model or an approved successor. Check the entire system and repair any leaks. Remove air from the system by bleeding it (See There should be virtually no loss in normal use. , but you still have to find out why the fluid level was low. Lack of fluid is easily fixed by topping up the Trying to smooth the bore with abrasives only makes it worse, and the roughness quickly wears out new seals. In this case, fitting a new cylinder is the only remedy. , absorbing moisture from the atmosphere, which can cause corrosion in the bores. May have worn or become rough - hydraulic fluid is If the system has air in it, the action of the pedal may feel 'spongy', whereas with other faults the pedal may feel normal, although the clutch does not work properly. In either cylinder, so that the slave piston does not travel far enough to disengage the clutch.Īny sort of leak will have the same effect and air might get into the system. May allow hydraulic fluid to leak past the Repeat steps 6-10 as many times necessary til you’ve got good pedal feel.Fails to disengage fully when the pedal is pressed, the problem may be theĬlutch, however, the problem may lie in the master or slave hydraulic Let the car sit 5-10 min to allow any aerated fluid to settle.ġ1. Once the bleeder is closed and clip inserted you can pump the pedal a few times to refill the hydraulic cylinder and get an idea for where you are at with pedal feel.ġ0. Once no more air is coming out, with the clutch pedal pressed in all the way, put the fluid line back in all the way, insert the clip, and have your helper let the pedal out. You may have to vacuum all the way to 25-30” if necessary to get all the air out.ĩ. Continue to have your helper pump the pedal 2-3 times then hold the pedal down as air bubbles start to come out. Pump up your vacuum to about 20” or so, and have your helper push the pedal in all the way and hold it, you should see some air bubbles coming out now.Ĩ. Don’t pull the line out too much or you will introduce more air into the system.ħ. Pull the clip out that holds in the fluid line, then pull out the fluid line just about 1/4” or until you can see the fluid start to flow. Get your vacuum pump set up and attach to the bleeder nipple by the bell housing. Now you can take the cap back off the fluid reservoir. It seemed weird to me the do this with the pedal pressed all the way in, you would think it would be the other way around, but this is the only way I could get it to work.ĥ. At this point with all the bubbles gone and the pedal pressed in all the way to the floor, you can put the cap on the fluid resevoir(to prevent fluid from running out) and go ahead and remove your hose from the bottom of the master then click the clutch line/hydraulic assembly back in and re attach the clip. At this point you can have your helper begin to pump the clutch pedalrepeatedly until no more bubbles can be seen.Ĥ. Be sure your fluid reservoir is topped up with the cap off.ģ. I left the top line connected (the one that feeds from the fluid reservoir to the master), then unhook the bottom line (the one that feeds into the slave cylinder.) so anyways unhook that bottom line then attach a suitable fitting+hose into the hole where the line was and feed the line into a container of brake fluid.Ģ. I could not get the master to bench bleed properly so I chose to bleed it in the vehicle. We spent hours upon hours trying to get the clutch bled properly and I figured I would share my method in hopes that it will help someone.īE ABSOLUTELY SURE to keep the fluid reservoir topped up throughout the entire process otherwise you will introduce more air into the system and restart the whole thing.ġ. I have been working on a 2003 Saturn Ion (non turbo) and we replaced a clutch pedal along with master cylinder.
