Some places call it a “Dual Circuit Brake Servo” or “Dual Diaphragm Remote Brake Booster”: The good news is that a Spanish brake company by the name of Iruna has started manufacturing dual circuit hydrovac units again! There were no reputable modern makers of hydrovac boosters, and many from the 60’s were either too old to trust, or single circuit so they could only run the front brakes. Why haven’t many people used them in recent times? Because automakers leap frogged to using brake boosters directly connected to the master cylinders and to hydroboost. This technology is actually not new at all, it was used on upgrading cars in the 1960’s that came from factory with manual brakes. It can be placed literally anywhere in the car. Hydrovac is the answer! Its essentially a remote brake booster, that is easily plumbed in line to your current master cylinder lines and just needs you to run your vac line to it. Here is where we take the next step forward to solving this problem once and for all. So here we are, its 2021 and none of these options seem that great. This eventually lead to a hydroboost system you could get from Sikky, that they no longer offer, but could be plumbed fairly easily for LSx swaps. It proved to be more problematic than worth for most. Early on this meant looking at systems like those found on the E23. People early on were also experimenting with Hydroboost, which basically used power steering pressure to drive the booster. The problem however, is that try as you may, you’ll still never reach full power brake comfort. The break through in going this route was that with 3 small bore MC’s (instead of 1) you could get in a much more reasonable range of pedal pressure. I was at the forefront of this back in 2014 with this post:Į30 boosterless brake bracket (booster delete) manual brakes for swap cars The E30 community eventually moved to using boosterless (manual brake setups). This method requires a good amount of messing around (cutting, welding, fabrication) and leaves you with a solution where if you get in a car accident, that long rod is going to be the first thing coming to say hello. In the early years, the solution was to use a E34 brake booster, by placing it behind the drivers headlight and running a long metal rod. With a V8 swap, there is no room for any kind of brake booster in the stock location. If you’ve been researching doing a V8 swap into an E30, you’ll quickly learn that one of the major dilemmas is how to solve the brake booster problem.
