Do Not assume you bleed Farthest cal/slave from MC First on most cars.
GM and others FSM Assumes the system is "Dry" after major work, replacing MC, etc.
FSM plumbing drawing and bleed text Are Correct.

Their Bleed plan for Fiero is "faster" as tries to gets air out of Rear line at First SHORT Path then purges air from the rest of the axle set.

Fiero Front Brake bleeding likely doesn't matter much as both lines are on First T built into the Combi Valve and have longer lines to both wheels.

If you replace 1 cal/slave then can Only bleed the axle pair for Most vehicles. Air will Never get to the other axle unless system have Huge problems.
Even this is overkill for some pair sets... For Fiero:
Replacing L rear cal or hose likely won't matter but do same R rear cal or hose might because that side has a Very Short line to the T.
Fiero fronts have 2 lines from Combi Valve and replacing 1 cal is Very Unlikely to get air for other if you work quick and MC doesn't go dry.

Hard lines have basically a sump where bends under the frame at the wheel and this sump will block air getting in to replace cal or hose. Air can't get passed thu them but Fluid will flow out and worse if you open the MC tank.

Most times you replace both cals/slaves as a set. One bad then likely other is bad too and don't what to do the job again. + Same reason you replace worn out pads and rotors on same axle so both sides work the same and w/ same pressure.

Some Bleeder "Problem children..."
Some Vehicles have "Cross feed" system and have RF LR as one set, LF RR as other set. I think old RWD Chevy Monza is one of these but many FWD Non-ABS has this too.

If a vehicle has ABS then you have a lot more issues/problems to bleed the whole system after major work or replacing MC because many ABS have very strict rules and equipment to get air out of ABS "box."
