I bought two clutch master cylinders for my pontiac 2004 grandam. I followed the instructions on both, i filled up the reservior, pump the clutch 20 times, pushed the peddle to the floor, open the bleed screw and let fluid out. then i tighten the bleed screw and the plunger in the clutch master cylinder got stuck again..... I repeated it on the old clutch cylinder and it stuck too.... What am i doing wrong? How do I make the plunger come back out.Ken

Replace Clutch Master cylinder twice.
Replaced the Clutch slave cylinder
when you say clutch plunger what do you mean?when you bleed it the pedal gets stuck down to the floor and you have to pull it back by hand ?
Yes that is what happens... when you disconect the plunger, the part under the enigine that pushes in when you push the clutch in..... got stuck all the way in...... Which means when you push the clutch down and lifts back up it does nothing..... That is why i said the plunger gets stuck in...... It pushes the fluid....
you replaced the clutch slave cylinder ?you removed the transmsiion and changed it?
im confused on which plunger you are talking about.you mean the slave inside the transmission will stick all the way out and not return ?even when you pull back on the pedal by hand?
Oh My Gosh....
You know where you pour the fluid in the Plastic Container?
THere is a hose that runs down to a Plunger/pump section/ what ever you want to call it and it mounts on the wall on the oposite side of the clutch in the car. When you push the clutch down a rod goes through the Fire wall a pushins against a plunger that moves with the clutch.... However..... The plunger does not come back out.
ok so the plunger you are talking about is the back part of the clutch master cylinder ?
yep........ and it is stuck all the way in.... can't bleed the system..... I explained in detail above what happened.
i have never seen this before lets see if another expert has.hang on another expert will reply back to you
Relist: Other.I had to explain things to him... it took about 5 or 6 replies before he got what i was saying.... THEN HE FINALY said he didn't know
Thank you for using just answer.com,I look forward to helping you, Doug. First thing we need to do is get the plunger to return ,you can try tapping the end of the clutch master if it returns then we need bleed the system, this has been a problem with these vehicles , what you will need to do is buy a vacuum pump kit that comes with the adapters to pull the air up out of the system they cost $ 75.00 make sure the clutch master is full apply adapter and put system under a 25 inch vacuum, and wait ten minutes then remove vacuum adapter and lightly push down on clutch pedal but not push all the way down this is what causes the piston in master to stick in pump'push pedal three times then fill master and put under vacuum again you will need to do these steps two or three times , then try clutch and let me know , how it turns out please, Thanks Doug
I know that autozone rents/loans out the vacuum pump for the AC.... don't remember if there is a setting to 25 in ..... and the adapter, it plugs into the bleeder screw?
What puzzles me is the manufactor didn't state anything about having to apply vacuum... What type of Vacuum device are you refering to, a manual or electric?
Sorry but ac vacuum pump is not what you need , you will need a hand vacuum pump or a brake bleeder pump, with adapters , as far as manufacture of part thy don't give you all the info. needed I have done this numerous times with great end results. Doug

Please discard Corporate Bulletin Number 01-07-31-002A (Section 07 - Transmission/Transaxle). This bulletin is being issued to inform dealers of an improved procedure to aid in the ease of bleeding the clutch hydraulic system for the above listed vehicles. This procedure can be used anytime air is introduced into the hydraulic system. Following this procedure may also reduce the number of unnecessary parts replaced for low clutch pedal reserve and high shift effort.Verify that all the lines and fittings are dry and secure.Clean the dirt and grease from the reservoir cap in order to ensure that no foreign substances enter the system.Remove the reservoir cap.Fill the reservoir to the proper level with the required fluid.Attach the J 43485 (Adapter) to the J 35555 (Mity Vac), or equivalent.Brake fluid will deteriorate the rubber on J 43485. Use a clean shop cloth to wipe away the fluid after each use.Place and hold the adapter on the reservoir filler neck to ensure a tight fit. In some cases, the adapter will fit into the reservoir opening.Apply a vacuum of 51-68 kPa (15-20 hg) and remove the adapter.Refill the reservoir to the proper level.Repeat Steps 6 and 7.If needed, refill the reservoir and continue to pull a vacuum until no more bubbles can be seen in the reservoir or until the fluid level no longer drops.The vehicle will move if started in gear before the Actuator Cylinder is refilled and operational. Start the vehicle the first time in neutral to help prevent personal injury from vehicle movement and see if the transmission will shift easily into gear.Pump the clutch pedal until firm (to refill actuator cylinder).Add additional fluid if needed.Test drive vehicle to ensure proper operation.
