Changing Brake Hardlines to AN Lines

[PeaceOnesxWai]

I accidentally cut a chunk of my brake line mistakenly trying to shorten the breather line.. So now im thinking of changing the hardlines going from the BMC to the brakes to AN lines.

I have a buddy that has a couple feet of AN-4 lines laying around and i was wondering if the size would be too big? IIRC stainless S13 to 300ZX brakes are AN-3 but if i ran a reducer at the fender bulk will it have any effect with the braking?

Im currently running Q45s but im planning to change to 300ZX Brakes.

Also what size AN lines should the rear 300zx be running?



I dont need opinions on how costly an lines are and i should go hard line, i just want to verify the facts of what AN lines do i need to go with. Thanks!
