First gen Civic (1975) 1.5l 4spd CVCC

I frequently visit his channel. I just used ATF because I already have it and am trying to make my dollar stretch.

Rebuilt a wheel cylinder. It came apart fairly easily. I forgot to grab a before picture, but you can probably imagine what it looked like.




The center cap I powder coated is fighting to keep the red on the cap. I had to turn the psi up all the way to get it to start budging. It's slowly coming off. The chrome came off pretty quickly. I'd assume it has to do with the thickness though. I also lost the center cap in the bottom of the blast cabinet. When something is taking forever to clean off I like to break it up and do something smaller for a little bit. Well I was cleaning up the wheel cylinder and parts and when I went to start on the center cap again it was missing. I had to open the trapdoor and start draining the media out to find it.

I started removing the front brake parts. At first I couldn't figure out how to remove the wheel bearing. Then I remembered to check the chilton and not just the assembly diagrams on CMSNL.com. The chilton says to remove the caliper. Then undo the ball joint, tie rod, and strut and remove the knuckle. Then I can start dis assembly to change the rotor and wheel bearings.

Getting the axle out was actually very easy though. Used an impact on the axle nut and a single hit with a hammer and it popped out of the knuckle.

Master cylinder is apart!! I decided to drill and tap the piston (#3) so I could use a bolt as a puller. As I was threading the hole the piston started to spin. A little upward force on the tap and the secondary piston (#3) came out. The primary (#2) was a little bit of a pain. I ended up stuffing a paper towel in the reservoir opening and my finger over the piston retaining bolt hole (#5 is the bolt, hole between the outputs). Applied a little too much air pressure and bang, something launches across the garage. My hands were occupied blocking the holes and I told myself it didn't matter if I lost it. Now that its missing I really want to find it .



A little something showed up in the mail today as well...

I only scanned the pages I want some opinions about. What would be the best way to upload the manual? Not necessarily on Ecomodder, but where I can link to. I scanned it in as a pdf, but I have some other options too. I probably won't scan the whole thing in one sitting. So either upload sections or I could just wait until I scan all the pages and upload at once.

So the chilton says to remove the knuckle. On the first page it says I can remove with a slide hammer. Thoughts? I was hoping to not mess with the suspension yet so I think I'd rather use the slide hammer to pull the hub. If I can get the knuckle off easily though I think I risk less damage and where the car is parked right now getting the slide hammer on might be a little difficult.

Master cylinder is rebuilt! I think it turned out really good. I'm pretty confident that I won't have any issues with the new guts in the old body. Assembly went fine. The seals made good resistance as I was putting it in.








Edit: After looking at these pictures I realized I put the clamps on backwards.

Oh yeah. Look at that 1970s hardware! You're starting out strong on this restore. I like. I assume the Master Cylinder is not yet reinstalled. You're confident it'll work?

[M_a_t_t]

Not installed yet. I think I am going to remove the booster and clean it up first. It's covered in dirt like the master was and would really detract from the master cylinder. I'll grab some pictures when I pull it. Then reinstall the booster and master cylinder.

I am confident because of the fit the new seals had. The internals matched the original internals and the pictures of the rebuild kit for the original body I found at CMSNL.com. When I get the chance to find out for sure I will be excited because I will be bleeding the brakes!

If it sounded like I wasn't confident in the master cylinder it's because I have never done anything like this before.

Here is a dude who is doing some nice patient work on this CVCC. YouTube suggested it to me. Seems to belong in this thread.

Very cool. I watch his videos when it recommends one with a neat car. I haven't seen that one. Notice 1 handed steering with no power steering as well. When I got mine 2 of the tires held air so I put them on the front and the back 2 on dollies. I was surprised at how easy it is to turn at a stand still. Also his car is missing the original intake. I was leafing through the service manual and its actually temperature controlled. If intake air temp is below 100 F then it pulls air by the exhaust. Once above it switches to an intake thats open in the fender well. There is another where he drives a Honda-matic equipped car. I am excited to drive my car, but I have a lot of work cut out for me before that happens.

Does anyone have any experience with older radios? Mine has an AM radio that doesn't appear to work. I hooked a battery up to the car just to see what I was dealing with and I couldn't get any sound. Fixing it sounds like fun, but I'm not much of an electronics guy to know how to fix it beyond obvious signs.

I left a comment about the missing ring topper things (part #17 in diagram a few posts up). His were missing maybe he'll see the comment. Here is the scanned pdf file.

I have been having problems with my scanner. I've been just emailing the scan to myself instead of direct connection to my PC. It will only let me email 6 pages (3 front and back) at a time so it will be awhile until I get everything scanned in. Just a heads up

Fixing the original radio would be a restoration plus. You could work out a stealthy aux port as you repair so you might plug in a device and not be stuck with crap talk radio stations all the time. If you can't fix the radio, you could leave it in the dash and bypass it entirely with an aux cable for your phone. But the best is having the original unit installed at the factory in 1975 and still working. Pretty amazing after 45 years, if it can be fixed.

The scanned file looks like the two plastic rings in your photos that name the brake fluid. What am I not understanding? There is a missing piece of hardware?
