Bosch iBooster Retrofit

[Reinsch]

I took some rough measurements to assist people from a gen 1 perspective. Note that I have already flipped the master and the reservoir is stock 2015 model s.

thanks for that!

RHD model S has that in flipped config already. Plus brake pipe connection is on other side :

I'm following this thread as I have always found the DMC brakes to be lacking and maybe this is something I'd like to do on my car. Is the Bosch iBooster unit available on its own in the U.S. or would I have to find a wrecked Tesla to scavenge a used unit?

They are hard to get ahold of new and I know the gen 1 boosters are about 1200 bucks. Your best bet is used wreck parts. Mine came from a tesla s 2015 with 35000 on the clock. 375 on ebay saved about 100 bucks by making offers till someone accepted on my 3rd vendor attempt

I removed my old master and booster tonight in preparation for my ibooster install and I was curious what the best course of action is for the brake pedal clevis rod. Its much shorter on the ibooster vs the original one.

[Reinsch]

there is always some adjustment.

If not enough, you can cut the shaft, thread one end with left thread, the other with right and use roman screw.
or thread them same and use long nut, but for adjustment you will need to remove pin each time and unscrew half turn minimum.

There is also option of welding extension in, or making new shaft to your specific dimension.

I have a model 3 booster in the mail right now. I will bolt it up when it gets here. I intend on retaining the stock delorean master and reservoir.

how's that ibooster or yours? Does it fit ?

if you read the message you can deduce it's still in the mail.

indeed. Date indicates it was in mail 7 days ago.

I found a supplier that can make a drop in replacement clevis rod suitable for the DeLorean that will screw in place of the tesla clevis. The DeLorean clevis is odd because it's a 12mm pin. Most brake clevis pins are 10mm from what I've seen, including the stock Tesla one. So just extending the iBooster clevis rod is not an option.

My custom clevis rod is arriving in the mail soon. I'll try it out and see how it works. I plan on offering these for sale assuming it works well.

If you have a welder you can easily make an extended clevis. I have done this with my wilwood clutch master.

My model 3 booster was commandeered by Customs, said it cannot travel across the US/Canada border.

I did a bit more research and found the 2017-current Honda CRV has the same booster as the Model S, with a different (remote reservoir) master.
I was able to skirt around the "tesla tax" and purchased it (from a Canadian Junkyard) for even less than the Model 3 booster which was already less than the Model S booster.

Once again I will be retrofitting on the delorean master cylinder, will update when I get something together.
