This makes my workday better regardless of topic. Cheers 🥂.
After watching this I now have a much better appreciation for all the R&D that Mazda put into the brake system of my 32 year old Eunos! Wow, Keith that was a brilliant video - especially the different gearing/ratios of individual brake system parts. I feel that I have nearly reached 'brake enlightenment'!!
Glad to help!
If you're thinking about removing the booster, there's a very easy way to test out what it's going to feel like. In a place where it's safe to do so (preferably a long hill), get up to speed and turn the engine off. Pump the brakes a couple times to deplete the booster. After a couple presses, you'll feel the boost go away and the pedal firm up. Get to know your brakes and ask yourself if this is really what you want. I'll say, in an NC it's pretty outrageous. You'll also experience a power steering delete with this maneuver. IMO that feels really nice until you start making real G-force, at which point it becomes a situation.
I've done this kind of thing quite a lot, because I used to hypermile Hondas and still have some of those habits. It's pretty interesting to see how different cars are boosted. An unboosted NC requires about the same force as an unboosted 10-passenger Lincoln Town Car limousine, albeit with much less pedal squish. With an EF Civic or CRX, you can lock them up without too much strain.
This info makes a great agrument for installing reinforced brake lines if you do nothing else.
what does the brake line ID dia affect the pressures ??
That's a fluid dynamics question, and this isn't the best platform to answer it in great detail, so I'll keep it at a high level. Tubing causes resistance so, the longer the line the larger the ID will need to be in order to maintain a certain pressure at the outlet. Standard brake tubing is 3/16" and 1/4" which shouldn't have much pressure difference between the two at a given length.
