I have a 1997 chev camaro and i just bought a cluck master cylinder for it and when i installed it. It started leaking in to my car when put fluid in it is it bad?

did you bleed the slave cylinder when you replaced it? if so check the clutch master cylinder it could have bad seals and the seals are not pushing the fluid like it should.

fill master cylinder, start at right rear. the way I do it is make sure cap is back on master cylinder. pump the brakes a few times then hold them. have another person open the bleeder valve at the tires until brakes go to floor. hold them down until bleeder is retightened but be sure master cylinder is not out of fluid. then go to left rear and do the same procedure, then right front, then left front. check fluid and if air is all out there should be brakes. good-day ! THIS IS HOW I HAVE ALWAYS DONE IT ! heres a little trick of sorts. you can change a master cylinder, and if you bench bleed it first. and no fluid is lost from the master cylinder lines you do not need to bleed the whole system. but make sure cylinder is full of fluid before putting on vehicle and all air is out of master cylinder.

It's your master cylinder. The part is about $55.00. Fluid leaking onto the floor boards is an indication that the seals on the Master cyilinder have failed. I would fix this as soon as possilbe, as the clutch might quit working all together any time.

Bleeder screws are full of rust. Remove then totally and see if fluids comes out. . If it does replace them . If fluid does not come out there is a blockage in caliper ot master cylinder. Or possibley Master may have an internal leak. Try removing bleed screw first and pumping master . Remember fluid is a corrosive place a rag over bleed screw opening prior to pumping master and wear eye protection.

Check the clutch master and slave cylinders for leaks, look behind the rubber boots as the boots can trap the fluid. If all of that is good then you use normal bleeding procedures: step on the clutch, have someone open the slave bleeder to let fluid and any air out, close slave bleeder, repeat.

You will need a set of combo wrenches (SAE), some clear tubing that fits snugly on the bleeder valve, a jar to catch the fluid, brake fluid and a buddy to press the brake pedal. Disconnect the line that comes from the master cylinder from the slave. Use the jar to catch any leaking fluid. Now remove the slave cylinder and install the new one. Reattach the line. Take the clear tubing and push one end on to the bleeder valve. Put the other end in the jar. Fill the jar with a little brake fluid to submerge the end of your tubing. Open the reservoir on the master cylinder and fill as necessary with fresh fluid. Okay, open the bleeder valve and have your buddy pump the brake pedal a few times until the fluid starts to come out of the valve. Close the valve and have them pump the pedal a few more times and then hold it down. Open the valve again and a rush of fluid and bubbles will come out. Close the valve and have your partner release the pedal, then pump and hold it down again. Repeat this process until no more air comes out in the fluid. Make sure you are checking the fluid level while bleeding any hydraulic system so you do not accidentally allow it to empty, which introduces air into the system. If you can get them, use flare nut wrenches on any hydraulic fitting to minimize the chance of stripping the nut. They can be quite soft.

i hope this helps,

What you describe sounds very much like the clutch is failing to disengage.
Fluid level being fine and no leaks under the car is good, but doesnt mean there isnt something wrong with either the master cylinder, slave cylinder, or the associated parts.

Highly unlikely there is a fault with the flywheel or clutch as failures with these would normally give no drive in any gear.

did you bleed the master cylinder before you put it on the car .
New master need to be bench bleed before you install them then bleed all the brakes starting with the furthest one from the master

since the fluid is alcohol based it evaporates, sounds like maybe the fluid reservoir is leaking and the master is ok, in most cases the plastic fluid reservoir is transferred from cylinder to cylinder.

Either a line is ruptured, or the slave cylinder or master cylinder has failed. Is it leaking fluid? If you see puddles under the car, you have a rupture. If not, it's either the slave or master that has failed. Start with the slave, simply because it's less work and usually a lot less money.
