About $200 USD on eBay for a good used unit from a 2018 Honda Accord or CR-V (Bosch iBooster)

* Simple 4-wire hookup
* Get reduced pedal travel with no increase in pedal force. Say bye bye to long brake pedal travel
* use with a 10 psi residual valve for rear drum brakes
* good for "big brake" swaps

It comes with a 25.4 mm master cylinder. Is this too big for stock brakes? The 1200 uses a 17.5 mm master. Would make the brakes touchy/grabby?

For stock brakes, you could adapt it to work with the stock 1200 master, but what is the point? To make it use even less leg power? It's already easy to press the pedal on a 1200. By using a larger master, the pedal travel is reduced for a tighter/stiff pedal. All without the usual downside of increase leg effort when using a larger master cylinder

Great find, better than trying to use an old Valiant under the dash one which are very hard to find these days

superfastmatt on youtube had a video recently of using an electric brake booster from a tesla. My car (not a Datsun) has almost no clearance between the master cylinder and the hood so I can't fit a standard brake booster in because of the diaphragm diameter, so I think about the electric one sometimes because a Girling remote booster is so expensive.

Im hearing that the Tesla item is also a Bosch iBooster

In your sports car are you able to fit an extender tube? I saw that one guy using an iBooster had done that o space the master far away from the dash

here is an extender in a 1200

That "extender" was quite common in the Ford Escort twin cam and still available. Called a servo tower.

Thanks! Good to know there is a commercial solution, never seen anything like that here. We never got Escorts here (until the 1981 "world car" specific to the USA market)

I've seen multiple pictures of 1200s using them, usually in some far-away country
