So I bought a 4 door 90 Accord.... I didn't expect for it to run for much longer, so I sat in on the driveway until I managed to get a JDM F22B . I did my research did the swap myself. In the next week or so I hope to install a custom exhaust system and take her on the road for the first time. My clutch was working before I did the swap and now I can push my pedal to the floor and it will stay down. While I was doing the swap I noticed that the hose from my master cylinder was connected to the inake manifold and had the words "brake booster" written on it. Are the brakes somehow connected to the clutch? What do I have to do to get my clutch pedal to work? Sorry I know if I was kinda long winded

 

which master cylinder (clutch or brake) is connected to the brake booster vaccuum port on the back of the manifold ???

your clutch should not be connected to the brake booster at all, and the two systems are not connected at all...my guess is that it is either not connected right (via the slave cylinder on the tranny) or either your master or slave cylinder went out on you...try to post some pics of the engine bay (detailed) so that we can see if everything is connected right

 

The clutch hydraulics operate the same as the brakes - a master cylinder and slave (or wheel) cylinders and good old hydraulic pressure.

The clutch master cylinder may or may not share the same fluid reservoir. Check to see if there is any hydraulic oil in the system and, of course that all is connected.
I cannot imagine a Honda unit going south, unless it is 10 to 15 years old !.
Check also that a leaking slave cylinder has not lost lost all the fluid.

 

I'll have those pics up in a few min. I pretty much matched up everything b4 i connected it since the two engine blocks were almost identical. Since the pedal was working b4 the swap should I assume the slave cylinder is faulty first. How should I go about checking. There are no noticeble leaks on my tranny.

 

I'm not sure how to post the pics or if im allowed to?!

 

the hose i was refering to is the on at the top connecting to the master power cyclinder with the red label on the black cover. Both resevoirs pictured contain brake fluid. Which one is for the clutch?

 

Here are some more pics. I can get some more if you need me to get a better shot of something.

 

did you bleed your clutch master cyl?

 

no i didn't. Ive been searchin online for instructions, but can only find them for different makes, not honda

 

I had a similar problem recently. See here > https://honda-tech.com/zerothread?id=896551

More than likely, your clutch needs to be bled. It's simply a matter of connecting a hose to the nipple on the slave cylinder, and placing that hose down into a container with some brake/clutch fluid in it. It is just like bleeding the brakes. However, it sounds like you're in the situation I was in.
I had a ton of air in the line and had to manually push the pedal down with my hand and then pull it back up in an extremely rapid motion until the system began to build pressure. Remember to open the nipple every so often and let the air out. When the bubbles slow, close the nipple and began pumping again.
This is definately a two person job but some type of brake bleeding pump would work wonders for you.
