Re: disc brake conversion on 1st gen crv?
what rear disc set up is that from?? last guy that did it here told me it was from a prelude,
the other guy that went out from the tuning scene used a legend rear disc set...
im willing to "donate" or pre order if someone would do this....
thanks!
all what ive been doing in the past was checking w/c trailing arm would work, the ITR ones
did work.. but to buy just the rear 5lug conversion is REALLY hard, i hope that guy in the
pic could mass produce or make extra of this bracket....

Re: disc brake conversion on 1st gen crv?
If we could make contact with the person to do this previously, I could very easily make these brackets / spacers. I just need the CAD file he used, or just dimensions to draw my own. I haven't found a way to get a hold of him yet.

Re: disc brake conversion on 1st gen crv?
I have something in the works as we speak. No CAD drawings though as I am not that fancy and don't need them either LOL! The design mentioned previously won't work on a CRV in my opinion unfortunately due to body design. Who honestly wants the rears pushed out farther than they already are to begin with? Not only that, but using what I assume is a 6061-T6 aluminum sandwiched between two pieces that have essentially a multi-dimension load at all times to add on top of the shear, bending, and compression forces that a brake caliper and bracket already see.
I am no engineer, but have exhaustively researched and read up on this before I decided to do it. My plan is to make it 100% bolt on with zero fab work required. Then there comes the problem of deciding to use aluminium versus steel for the bracket. When using aluminum as a rule of thumb you need at least 1.5x the thickness in material which can pose it's own issues. This considering the added costs associated with using aluminum as well as their finite life cycle, ability to withstand temperature, and corrosion resistance. It tends to turn to powder in short time when compared to steel.
There are many things to be taken into consideration other than just slapping together some garbage, let alone something that performs. With all that being said, I am also trying to improve upon the rear end options (within reason) to make something more affordable. I have been working on it for a years, but my interest in the CRV comes and goes... and right now it's roaring again. That's what usually happens when I don't drive it for months or years at a time HAHA!!!
PS - I wasn't really going to say anything right now about all this, but I guess gauging interest would be smart rather than wasting my effort in sharing. Everything has costs associated with it obviously, but more importantly my time.

Re: disc brake conversion on 1st gen crv?
basically my interest in having rear disc on my crv is 110% I would be willing to pre-buy a set if need be to get this off the ground. If it was all a bolt on affair, I would be very happy. I dont mind fab work, but for ease of installation and removal a bolt on set up would be ideal.
Now with all of this said if there were brackets....what proportioning valve would we be using on these set ups?

Re: disc brake conversion on 1st gen crv?
Well I worked on it (the conversion and the CRV) all weekend. Ended up having some hiccups unfortunately as the last time I had interest in this conversion was over 2 years ago = I kinda forgot where I left off LOL!!! So a few things are changing from my original idea, but it is what it is. I am hoping to finish up most of the swap within the week or two but won't be able to have it driving for a while longer since almost EVERYTHING under the hood and under the car is removed right now.
At this point I don't want to speculate on what will need to be done to use them. The only reason is I don't need people getting upset or start buying things or making modifications until I have a user friendly system that works. I have already bought and returned half a dozen rotors and calipers from various cars. The trailing arms just aren't made for rear calipers so some modifications will need to be made. When I have something worth posting I will definitely share it and keep you updated. Hopefully the brackets will be made by the end of the week. There doesn't seem to be much interest anymore, but either way please understand this is just a hobby for me and work and family comes first.

Re: disc brake conversion on 1st gen crv?
well if you have a fwd crv or want fwd I think its as easy as swapping the trailing arm from another 5 lug integra/civic. they are pretty much the same I know the crv front bushing is slightly bigger because I once got a sent a crv one for a civic and it did not fit.
it does look better and not saying anyone should stop trying because I want rear disc too, but I will say it. its pretty much zero performance gain for anyone wondering.

Re: disc brake conversion on 1st gen crv?
This is true, except if you road race, longer AutoX tracks, higher HP drag racing MPH, or even some spirited driving with higher speed slow downs and have experienced brake fade - you would want to get rid of the drums too. Once they heat soak you are screwed and there are no mulligans in real life. There are more advantages as well, but they have already been discussed in this thread. This conversion is only going to be for the true enthusiasts anyways due to the cost involved.
If you don't plan to track your car, I would highly recommend that you just stick with the stock brake setup anyways. Also, I was looking over the 4 picture collage some more and that is one huge hack job. If you look, half the pad isn't even touching the rotor and I see no e-brake provisions. It's purely cosmetic on that swap; however I do give them props for attempting it.
You say the front bushing is larger, but which one are you talking about exactly? The trailing arm bushing? If so, that's not true with an exception. You must of had the small bushing EF trailing arm. Take a look here (there are many examples but this was the first link):

Re: disc brake conversion on 1st gen crv?
Had some time to finish the fabrication of the prototype bracket tonight!!! I just figured I would post up a teaser picture for those interested. Also, YES, I know all about cross drilled and slotted rotors and their cons, but the price was right (FREE --> Donated) so I am using them for the mock ups and will most likely just run them afterwards anyways.

Re: disc brake conversion on 1st gen crv?
Well I ended up changing it some and reclocked the caliper. As it ends up it won't be exactly a 100% bolt on swap, but I did find a work around to make it the least invasive as possible. Basically at this point just waiting on material to show up for the e-brake cable connection. Have a few different ideas at this point but we shall see what I end up with. My goal is to not cut the e-brake cables as they are expensive and "rare" but it may not be astheticly pleasing LOL...
There doesn't seem to be much interest so I have been working on other parts of my car in my off time instead of focusing on the brake conversion. However I will say this much, the brackets will be made of steel. I tried aluminum and I refuse to push the wheel bearing outwards and the brackets would need to be MUCH too thick plus costs would go up significantly. I do have the ability to powder coat though and everything would be coated for rust resistance.

Re: disc brake conversion on 1st gen crv?
very nice, I would love a rear disc conversion if it looks good and isn't a hole job in itself, if I had to do a few things to swap then I would, but a almost bolt on system sounds great. Let us know if you go back and finish this.

Re: disc brake conversion on 1st gen crv?
AAAHHH!!! I had a HUGE thought out response typed out but my window crashed!!! GRR!!!
Anyways I am going to sum it all up quickly...
No, not it at all as you make the bracket to position the caliper. The problem is the trailing arm is absolutely not designed to have a caliper hanging off of it. In my opinion this swap has never been done before since if you look at the picture collage on the first page the pad is half way up the rotor due to the trailing arm design. Plus it doesn't have e-brakes. I have to have e-brakes as I always use them. As of right now I am focusing on RT4WD as that is what I have. Figuring out if FWD will work will be easy after I get it all done.
I am trying to make this swap the correct way. I plan on making a paper weight kit (not for street or track use
) that includes brackets, e-brake adapters, brake hoses, and hardware. I contacted a few machine shops and the rate is outrageous so to make it more cost effective I will do it all but even then it is only for the true enthusiasts on the price point. It's no different than the RT4WD LSDs I have done for people... gotta pay to play.
Sorry for being vague, but I don't want people getting upset in case I change my mind about something or expecting some high level CNC quality (not saying it will look like crap either though). Once I have something worth posting pictures of I will be making my own thread on this. I am still a ways out on driving it though as I have quite a few custom projects going on all at once for my CRV. Trust me, there is more to come and I will be shedding some light on a few things as well as misinformation cleanup.

Re: disc brake conversion on 1st gen crv?
What exactly are you even talking about? Did you even read what I wrote or just quoted me and responded? Look at the picture on the first page and see what they did. All CRVs have e-brakes from the factory - federal mandate. I am saying the swap on the first page doesn't have e-brake cables hooked up and the pad isn't even remotely centered. This looks like the same issue with the Del Sol version...

Re: disc brake conversion on 1st gen crv?
YOu said it didn't have ebrakes. Not sure what you mean but that, either the e-brake cable can't be used with calipers...or something.

Re: disc brake conversion on 1st gen crv?
Yeah I did say that about the CRV "conversion" on the first page of this thread. Zooming in on the pictures I don't see the e-brake cable anywhere or even provisions for one on that disc brake swap that is on the first page. The other issue is the pad isn't even close to fully seated on the rotor surface and the radius of the pad doesn't match the rotor. Basically a lot of things going on that are wrong with that swap.
The aluminum brackets on the first page for the (I think) AWD Del Sol conversion doesn't lend itself very well to the idea of hooking up e-brake cables either. The angle is the main issue on that design and caliper selection.

Re: disc brake conversion on 1st gen crv?
Made more progress this weekend. I made a master template and figured out the e-brake without cutting the cable - YAY! Although, it isn't exactly esthetically pleasing due to not cutting the cable (at least IMO, some say I am a bit of a perfectionist though).
SOO... if all keeps going well and material arrives, I should have something worth posting about in around a week. I am going to have to figure out how to get some time on a computer to make the Write-Up for it. It's somewhat involved, but easy if you are mechanically inclined. The main issue is my CRV is still completely torn down and I may need someone to be a guinea pig unless people want to wait at least another month or more LOL! I have noted everyone's PMs thus far.
Here is a picture of the final clocking location. It may look the same as the first one, but I assure you it's not. It is MUCH better in this location. Stay tuned for more!
