Bosch iBooster Brackets for 60/80 Series – Tested in Moab, Ready to Go

I need to address the 100% stock braking system on my heavy 80. This would be a good place to start.

Do your brackets work with any Bosch iBooster, or is there aspecific model/application you need?

I'd want to know this as well. The estimated $300-$400 for a complete kit sounds great, but for future service/replacement/maintenance needs, I'd want to know the source of the booster used.
 
If this would work on a RHD 1HDT I’m in for one
 
Another question-- how hard is it to brake if and when the booster fails while you are driving? On a stock vacuum booster you can still brake with some extra effort when the booster fails. Is the same true with these types of boosters?

I would guess that the answer is yes, but that is just a guess.

Put me down for one. Got the booster already.
 
Sorry if I missed it, but is this just the bracket, or a "kit", ie: everything else needed (?wiring, fuse, etc) except the iBooster (Gen2)?

@torfab It appears you have a Gen2 Bosch iBooster pictured, is that correct?

Any gotchas with this setup with a LHD 1HDFT 80 series? If not, put me down for one!

Where did you get your booster? What car did it come from?

eBay. Hoping it’s the right one. Was looking to do what torfab has done and drew up the MC adapter already. So this is super exciting for me.

From what Ive read of testing 90lbs of input pressure gives 250psi line pressure when power is off. 1200psi when power is on.
 
while this will decrease pedal effort and increase clamping force, it might also accelerate brake fade and warping of the rotors if used on the stock brake system

Brakes come down to generating heat and then shedding that heat. If this setup overwhelms a stock system it could be a problem.

Not saying it is a problem. Just be aware of it until data shows it’s not a concern.

Anyone who thinks I’m overly cautious go find the video of the Chevy K5 (?) on lions back. I honestly don’t know what failed but wouldn’t wish that on anyone.

How does this compare to the stock 80 series vacuum booster? And how does it compare to the hydroboost solutions?

Actually, now that I think about this would seem to depend on the master cylinder used. As I understand it, the torfab adapter lets you keep the original 80 series MC. Same with PIP's hydroboost adapter.

Would take a bit of research. I dont know what the 80 series brake pedal applies for physical foot pressure to the booster rod.
