Rear Disk Brakes: Who's interested?

hybrid DET · Feb 28th, 2003, 10:30 AM

Hey guys,
I have been working on the caliper bracket for the B12 rear disk brake conversion again. I am modeling an improved design in 3D right now and will probably be making a stereolithography prototype this weekend. If all goes well I will be using the prototype to make a casting mold from. Depending on manufacturing costs, I may be able to produce a few sets of these.

None of this is a garentee but, who would be interested in these caliper brackets?

Don't have a B12 but was wondering why do a cast bracket? Why not CNC from a solid piece of material? Check this out:

hey myetball, um that's HIS car ur referring to in that article. yo charles, i would definetly be interested, how much though and what disc would i use and would i still have to grind off something like u had mentioned before

I would love to produce them via CNC mill. However, the manufacturing and material cost would far exceed what most of you would pay for the part. I think time on the CNC machine runs up to 100 bucks an hour. The main reason is that I have an opportunity to either cast the part myself or have a company who works with my university do it for me.

It certainly is a small world.

Not sure what the cost on this whole project is going to run me so I don't have a price right now. If the cost goes to high, which it may, then I wont be able to do it. I figure I'd at least try first though.
I would definately sell the kit with the caliper bracket and the modified piece of the caliper so it would be a bolt on affair. You would have to find a set of 91-94 Se-R rear disc brakes though.

at that point would i need to upgrade the mc or would my stock one be enough to run all 4 disc?

count me in !!.... but if you cannot get that thing done from a casting mold would you send me the 3D modeling (mastercam) so i could have some made around here on the mill !!!

.... BTW nice job talk about RnD !!

... its about time someone do something with the platform

10 years late but thats awesome !!

Yes at that point I would recommend trading mastercylinders. The stanza one will get you in the ballpark and it's ten time better than the b12 unit.

Sorry, but the design is proprietary. No offense, but I would be a fool to send out the 3D model to someone. Kevin and I, have worked pretty hard to develop it and I would be royally pissed if some machine shop made a dozen or so of them to sell. Nothing personal.

The stereolithography is being built as we speak. I'll let you guys know how it turns out.

and yes it is about time someone make something for this car!!!

(raises hand)

I'd love to get my hands on a set of those brackets. It's cool to see that you did that through your school. Maybe school is good for something.

Crazy-Mart · Mar 2nd, 2003, 08:15 AM

Hybrid i know wath it is, i work in molding (plastic) and every mold is Tm, patented, designs and blueprints are too !!...

i just hope your going to make it !!... it would be cast iron, if so i could deburr those and paint them before putting it on !!

If the price were right, I'd certainly be interested; I'm due for some brake work all around anyway.

Not to go around your idea, which sounds awsome, but I read somewhere where you can convert them to rear discs using the disc setup from a Pulsar?? Don't quote me, but I'm pretty sure I read it somewhere.

There's a way to do this with just a quick trip to your local junkyard and tad bit of fabrication. I have had my set-up for 5 years and it works flawlessly. I will not post it on a local board because this will be done at your own risk and cannot and will not accept responsibility if something was done incorrectly. Email me at my personal email address and I will share with you all the details needed. This is not an attempt to under-mind hybrid or take away from his ideas, but there are some very talented people in here (Myetball, blownb310 just to name a few) that would be able to do this mod in about 3 hours and not have any dramas or need to have an instruction manual. To those that are not that talented, Hybrid's method will be the ticket for you. I hate to have something and can't share it with the rest of the individuals that can benefit from it. And the only reason why I didn't bring it up before is it never really dawned on me that there are plenty of people that want this feature and don't have a clue as to where to begin. This is a boost_boy's do-it-at-your-own-risk briefing.

lol, thanks bootst boy. yes there is another way but in never felt comfortable with it for some reason. But it has worked on yours and john's b12s with no problem.

Eric, school sucks... you have to make it not suck by doing projects like this.

I still havent checked out the stereolithography yet but it is done... I'll get back to you guys... This is still a long shot.
