1" bore MC upgrade question 85 4Runner

I have never messed with hard brake lines before so Im trying to be very cautious about this next step.
I found a new 1" bore MC but as you can see the fittings arent positioned the same.
Im wondering if I could just break loose the front line (blue) at both fittings and pivot it CW 90'??? I may have to tweek it slightly but Im just not sure if its a good idea. I already went to the junk yard and looked for a pre bent piece that would work but the yotas in the yards around here are picked CLEAN!
Any info you guys might have to offer a noobie like me on the matter would be greatly appreciated.
Thanks in advance

loosen both ends tilt and bend the tube as needed. That's what I did. Just be careful and not make any excessive sharp bends if just using your hands and not a tube bender. You can either break the line or kink it causing fluid flow issues.

Personally, I'd just go to O'Reilly and get a tube bend/flare tool...they're $20 tops if I remember correctly. New tube is cheap, a crack in an old tube you cranked on isn't.

if you think the pedal is a little too stiff like I did, upgrading that booster to a dual diaphragm will help with that as well. Did you remember to adjust that actuating rod? You might not have had to though, I didn't till I upgraded to the dual diaphragm.

I did not adjust the actuating rod.
I did feel like the pedal was a bit stiff but she stops like crazy now.
What exactly does to two diaphram booster do for the breaking power? The first thing I thought was, why do people upgrade MC and the booster when just the MC upgrade does soooo much.?

the booster allows more power to push the larger MC. It will still brake the same, but the pedal won't be as hard.

im glad you made this thread. i was wondering how easy it would be to bend those brake lines. i just scored a booster and a mc out of a 97 T-100 so im pretty pumped on putting that in my runner.

When bending brake line, I usually go around something like a small diameter pipe or ratchet.. Makes a nice smooth bend
