I'm having fun with my 4x100 conversion right now

Those wheels look awesome Hazwan! Great work on those. Color looks damn near identical to the wheels I painted for my Miata. The dark wheels looks great with the polished lip. And the 15's look so good on your car!

So yeah, I've been finding that the 81-82 Preludes use the same wheel bearings as my 81 Accord. But now I have to start my search all over. Maybe you're right about the 82-83 Accord hubs working though. Making up a spreadsheet of wheel bearing sizes and spline counts. Probably going to make a couple stickies after I get it all figured out. One with Hazwan's swap info for overseas people, and one with the USDM info.

Those turned out awesome!

If you were going for 2g Prelude rear discs I'd go with the 2g Accord hubs (& maybe early 2g Prelude) just for the wheel studs, though I guess they could be pressed into either Hub before assembly?
Still surprised hubs/driveshafts were different for US for '81 but there had been hints of this in Hazwans earlier 4x100 query post where we found their part numbers differed in US online partbooks for that year & the experiences of others with swapping driveshafts on '81's.
But Honda can be inscrutable. I found that Honda's Quintet; the Preludes closest cousin, kept the old driveshafts into '82-4!

Loving the color!

kso I've bought myself a pair of front brakes off an EF. I have no idea what the trim level was but it belongs to a friend of mine and I got them off for pretty cheap. Still have decent amount of pad left too



Heres where I fail:


Its exactly the same size grrrr. Oh well at least the new rotors are vented vs solid dick errr disk and the pad area is tiny bit bigger.

And A PROPER WORKING CALIPER WOOT!

Did I mention that my current calipers are junk? Its missing the anti-rattle clip(s), the sliders are junk. That alone is definitely worth all the effort in upgrading the brakes haha

PICS to follow soon.

[2ndGenGuy]

Just getting good calipers is going to be a huge improvement! And being able to buy new slider pin kits, and have them properly greased is a godsend. And vented rotors FTW! I don't think the size of the rotors is that big of a deal, though the CRX rotors I have do seem to be slightly bigger. But I doubt they'd fit under those calipers anyways.

[Hazwan]

Prettyyyy

[2ndGenGuy]

Pretty!!!

[Hazwan]

Had the calipers rebuilt with brand new seals, pistons and stuff.


Wire brushed the rotors.

Keep the PICS coming!

[SylusMk2]

hellz yeah i wanna see ALL the pix! lol i wanna see how these work

[79cord]

Very nice!
I thought almost all '88-00 Civic were 242mm Dia, except for Vtec models 262mm & maybe 282mm foe last Type-R models.

I have no idea myself, maybe its different between the markets? I believe mine came off a low end EF so that explains the 9" rotor? Either way its not a huge loss seeing how the EF calipers have a bigger piston in it not to mention THE WORKING SLIDERS <3 hahah. Its still a huge upgrade from the stock setup either way so its well worth the $$ I paid for them (cheap btw!)

Anyway onto the PICS update!

EF caliper bracket on top vs 1g bracket on the bottom


1g lude rotor vs EF




Yes, I repainted the used rotor haha.

EF on the left, 1g on the right. Similar pad surface area (N)


Ew die!


EF dick err disk.. on


BUT! Theres an issue:


NOES IT RUBS (N)

3mm washer fixed it though

[Hazwan]

Pads (used, because I'm cheap) on


Plenty of life left haha


All bolted up


Proper working sliders <3


My 5yo niece freaked out when I told her that I'm bleeding


HUGE piston compared to stock 1g. That alone should be a good upgrade from stock no?


All done




So how does it work? Who the fuck knows. I need a friend to help me bleed them -.- I tried building the pressure bleeder but it turned out to be a disaster lolol

[Hazwan]

Just installed the EK booster and master cylinder....


FUCK I need to stop buying things that "just because it looks like it might fit". I didn't realize that the EK booster is actually 9" vs 8" for the EG booster that I'm currently using.

I've managed to squeeze the booster in except it hits my accelerator cable and broke the tab thinggy that held the cable on the firewall FFUUUUUUUUUUUUUUUU gotta sort that out tomorrow. I don't want my car to go LOLTOYOTA on me or something dfsdfsd I am so stupid dfsfs.

And I still need to bleed the brakes. Its kinda hard to do so without friends around lol.

Oh and the main reason for the EK booster/master cylinder is my EG booster is leaking and this EK booster/master cylinder popped up for sale last week for real cheap. I thought "hmm that looks like it might fit!!" thinking that I can reuse my EG master cylinder. WRONG! The base is different, forcing me to use the EK master cylinder as well.

What a pita it was. There is basically no room under the dash to get the nuts out.

BTW whats the size of the stock 1g master cylinder? I had 13/16 for both my EG and EK master cylinder and I'm curious if the added front caliper piston size have any effect on my pedal effort. Is the bigger booster gonna do anything at all?

[lostscotiaguy]

Assuming that your master cylinder (Piston) is the exact same size I would imagine that the larger brake pistons would require more fluid when being used. However I bet the difference probably wont be noticeable. A larger brake booster (Bigger in circumference) should = less pedal effort. The larger diaphragm in it will allow for more "vacuum assistance" from the manifold vacuum while pushing the pedal. I may be talking out my ass but I think you would end up having a little more pedal travel, but less pedal effort. Not to scare you but I'm also wondering about your brake proportioning valve...it's tricky to explain why (It would take too long) but that valve may cause you troubles when you get everything back together. I might have just missed it on here but are you doing anything with the rear brakes as well?

[2ndGenGuy]

Hmm, well I just picked up an EG brake booster along with a 7/8 master cylinder. The stock master cylinder is 13/16, so I think the slightly bigger booster along with the bigger master cylinder should work well together. So just to be sure, you had no problem fitting the EG booster? Mine seems bigger than stock, so I guess I'll find out. Worst case, I guess I'll just run the stock parts, which seem to stop the car great, other than the fact that I have no power assist.

I also had to space out the 86 Accord calipers that I used. No big deal. I believe 79Cord also had to space out his CRX calipers.

So 7/5 is bigger or smaller than 13/16? Stupid numbers confusing the fuck outta me ahaha.

I'm gonna bleed the brakes today so I'll keep you guys updated.

looks like SEX. dafuq is up with red brake fulid??

[Hazwan]

LMAO who the fuck knows. Apparently its common over here so idk? And yes its brake fluid and NOT ATF LOL.

Anyway so I've got my nephew who happen to be into cars (and love the classic Hondas too!) to bleed my brakes. Took for a drive... OH FUCK feels sooo much better now.

Theres a slight issue: my right caliper seems to lock first when I do a hard braking. Frozen caliper? But it seems to drive straight without any pulls

I still gotta jack the car and check if its stuck/rubbing or something on that side but in normal braking, it feels great. Pedal effort is pretty much the same, if not better but overall, it feels great. Its nice to have working brakes again Worth the effort IMO I can imagine 2ndGenGuy's brakes gonna be a lot better than mine. Oh and my tires have like 15% thread left :p

[79cord]

Yep mine has washers too, probably only 2mm though.
Looking beautiful all freshly painted.
I was wondering about your front/rear proportioning as well if the front brake wheel cylinder/piston was that much bigger; more fluid required to move it. I guess that should make the rear lock up first though.
I never looked at mine when fitting so don't know how it compares, but thankfully never had any problems.

Glad to hear it stops great!

Yeah, 7/8 is bigger. I just convert everything to 16ths in my head. So 7/8 = 14/16. It's not a lot bigger, but we'll see. Just hope this junkyard booster is good.

[Hazwan]

Anybody have any idea why the front right wheel seem to lock up first under hard braking? I've jacked the car and checked for frozen caliper and what not and everything seems fine. The wheel would spin freely for about 2 turns before it went to full stop, just like the left side. I'm suspecting that its my tires though. I'm gonna swap them to the back and see if it would make any difference.

So far everything seem and feels fine. Drives straight without any pulls. Just had a long overdue alignment earlier today too haha.

EG booster


EK booster


dfdsf


Okay wheres my hammer? Yes I'll repaint the part where I hacked with my hammer lolol


There it fits

[2ndGenGuy]

Hay your brake booster is on the wrong side!
