Default clutch problems already!!!

I just put a new ls6 clutch/new flywheel/ pressure plate/ pilot bearing/ and slave. everything was working ok then at like 700 miles the clutch started engaging like right off the ground. I can no longer get in 1st or reverese with clutch. is it possible the master cylinder **** bed. it has 116 k. also car is surging forward even with clutch all the way to ground. I rebleed the system with mitty vac didn't help. I can get into any gear when driving no problem.

Has it ever been replaced(MC) that you know of? Most likely that is the culprit. Take a light and look up, under dash to see if it is leaking fluid. I bet it is.

no it hasn't been replaced I'm sure of it. the previous owner didn't replace crap and take great care of the car..my slave was shot that's why I replaced that so I bet the mc just followed. if its not leaking could it still be bad? I'm gonna check in a little bit. from the symptoms does that sound like a mc problem ? everything was going well and that is only non replaced part with clutch install. when I got car I did full brakes, rear axles , and rear wheel bearings.

MC and slave usually live and die together. The hydraulic action usually weakens the same way and at the same time a slave does. If it's an original piece(MC), it's been a good one. I'd start there.

Sorry you are having problems. Have you considered the Tick adjustable master cylinder? I am not certain how much benefit it provides over the stock MC when using a LS1 or LS6 clutch assembly. I primarily researched it for use in combination with a Monster level II clutch.

My project is stalled because I am still waiting on my clutch/flywheel/slave from Monster, and I found a single needle bearing stuck to my oil drain plug.

After I installed the new LS7 clutch with new slave and new Master, I couldn't get any gears with the car running. The new Master, like OEM went bad while the car was still on jack stands. Ordered new Tick MC and solved all my problems. It's pricey, but it works, and to fix my car I really didn't care what it cost.

thanks everything was breakin in good. it has to be the dam mc it is now engaging like right off floor so it dosnt have enough strengh to work the slave it my guess. I'm going to replace tommorow with a oem for now. I just dont have the cash for a tick. I'm able to drive . I shift without clutch. I'll update if it fixes problem. I don't see what else it could be as every thing is new except the pos mc. sorry to hear about the needle bearing. for me since I got car been a lot of parts going . gm really makes some ****. is the master a real pain in the ***. it looks not to big of job.

I was only using my new MC (carquest) to pump the air out. On the second day I looked on my floor and saw a wetness on my rubber mat. Once I got on my back and looked at the shaft of the mc, I could see the fluid coming out as I pumped it. It was $90, but because I had such a hard time getting it in, I believe I damaged it. Either way, I had no choice but to order another one. I decided I was not going OEM again. The Tick is a much bigger and the quality is is unreal. But it is well worth the saving up for. Hopefully you will have luck when installing your next mc.

what's it like getting in. any tricks so I don't bust it. do I need to crack the bleeder n the slave to disconnect the hose to slave. another thing I heard if you disconnect the slave if your clutch pedal is hard the master is good. so how u know if its bad it will go to floor? I'm getting one from nap a . can I bleed after with my mitty vac or do I need to prefill and do something to blleed ?

Alot of people had no problems at all, but the OEM one took me a long time. But the Tick I did in under 15 min. For the Tick, I took that clump of wires under the brake booster wrapped in a wire loom, and took a rubber strap and pulled it up EVER SO GENTLY NOT TO SCREW ANYTHING UP! It just gets that clump out of the way.I didn't do it with the OEM one, but it would of helped me. For the Tick I started with it upside down, and once I was down there I flipped it. It worked great for me.Those 2 things I read on here thru a search.
I used the mighty vac, but just to pull the old fluid out. I had installed the Tick speed bleeder which makes bleeding easy. I also did it old school with the Tick just to make sure the check valve worked. I used my wife to pump the clutch while I cracked the check valve, after the pedal was kept on the floor. I pumped atleast a pint of fluid to get it blead. Some did less and some did more. I followed the directions on here above the Manual, where the stickies are for How to bleed the clutch by Tick.
Read the Sticky on how to bleed and dont let your reservor go empty! There is alot of info thru search on here with answers to all questions.

A good read on hydraulic problems (and why the stock master usually isn't up to the task of fully disengaging even a stock clutch): http://tick-performance.com/images/tickshiftfaq.html

My tick mc went in waaaaaay easier than I had read about on here. I installed it, adjusted it, and have not had to think or worry about it again. Great mod.
