Default Replacing Clutch Master Cylinder & Possibly Slave.....Questions First

So the clutch as gone soft on me and getting into gear can be a pain. I've got my b16 eg and don't know if i should replace both the slave and the master at the same time.

If I do decide to replace both, am I supposed to upgrade the clutch components from a teg since I have a b-series trans in my car?

Also, for you that have swapped in new components, on average what did it cost you?

Check to be sure which one is leaking (either down the firewall or behind the slave boot) and just replace that component. There is no need to upgrade clutch hydraulic components.

I'd replace both Use the parts from a Civic. Slave Cylinder is ~$40, Master is ~$130. Both are fairly easy to install.

Yeah my title is kinda misleading since I will probably be replacing the faulty part only.

Bought the car with the new ACT clutch installed and last night the pedal started to touch the floor when shifting (something that hasn't been an issue before)

follow the clutch pedal up to the firewall to see if any fluid is leaking, then pull the boot back from the slave to see if theres fluid in it. fluid in the boot=replace slave, fluid by the firewall=replace master. most people will say to replace both cause they tend to go at the same time and it only requires you to bleed the clutch once. you dont need to get any clutch components just the master and slave.

I dont mean to jack the thread...but I figure its a good place to ask, since its on the same topic.

My pedal gets super firm after the car idles for a time, and the clutch will slip when I start to drive it. Ive adjusted the hell out of the piston and bled the thing like 3 times (theres no air in it). After the car sits for a long time, not running, the pedal goes back to being engaged about 1" down and it no longer slips
What the hell is the issue?

Save yourself the return trip and replace both at the same time. They tend to go bad within a year of the other's failure and you'll just have to do it twice.

I had to recently replace my CMC... as it was leaking for a while. I replace the Slave when I did the swap just because the original was absolutely in bad shape.


Just use Civic parts when you replace them.

How do you feel about the NAPA parts? I picked up my slave for $22.

I've heard that NAPA and Autozone parts are fine as long as they aren't on high output applications.

I have ACT clutch and XTreme p/p, and don't know if I should buy OEM, NAPA, or Aftermarket. This is a daily driver and I could care less if the pedal travel was shortened.

Thanks. I'm running an Unorthodox Kevlar clutch. From the little bit I got to drive the car it was great. Stupid frickin trannys...

OP: For the new componets I paid 325 for my clutch (not sure if that's what you were talking about) and $22 from NAPA for a slave cylinder.

Ok so I checked the two spots out and I don't know if I've found anything.

The master cylinder where the clutch pedal meets on the inside of the firewall, I saw come grease and it did look moist but it wasn't dripping fluid while I would press and depress the clutch pedal.

Next was the slave cylinder and at that spot I don't know how far I need to push the rubber boot back but as far as I got it, it showed no sign of fluid.

ive never seen the fluid on a bad MC so i dont know if it looks greasy when the fluid leaks. but i dont think it should be moist. as far as the SC if you pulled the boot back just a little bit fluid would come out if it were there. my guess is your MC is bad IF its one of those two parts thats causing the problem.

Well all of the hose/pipe, looks brand new. Yeah there is grease but it looks like grease that has been wet or moist, if you catch my drift. I guess I should start somewhere and just replace that.

you got a friend with a civic? if so swap his/her MC and SC on your car and see what happens. its not hard to change em out and thatll save you from spending the money if the problem isnt your MC or SC.

Here is a shitty pic I took of what the m/c looks like. The more I see it, the more I think it's leaking so.....

gotta replace that thing soon... its progressively getting worse.

When I was going through my dilema as to why my car would go into gear without the clutch and not go anywhere the guy said a good way to check the MC is to push the rod in on the SC with 1 finger. He said it should be fairly easy.

If it's hard to push back it means the valve to the MC is getting clogged, meaning fluid can't get back, so it should be replaced.
