I will be replacing all four brake calipers on an '08 Si
To bleed the fluid I will be using a bottle of brake fluid with a hose + one-way valve on the hose (this has worked perfectly fine for me in the past, when replacing just 1 brake caliper)

But to replace all four calipers,
It is better to replace all calipers at once, and then bleed them one by one?
Or replace one caliper, and bleed it before replacing the next caliper? (does it matter what order they are replaced in?)

Any advice greatly appreciated

 

After doing some research I found that
the service manual says to bleed brake fluid in the following sequence:
Front Left , Front Right, Rear Right, Rear Left

Still not sure if it's correct to replace all calipers at once and then bleed the fluid, or bleed each caliper before moving to the next one

 

Replaced all four brake calipers successfully

A few takeaways....

1. The brake fluid must be changed BEFORE installing new calipers (otherwise you risk damaging new seals with dirt/contamination in your old brake fluid)

2. The bleeder screw threads on new calipers MUST be treated with anti-seize BEFORE introducing brake fluid into the new calipers (otherwise you will be fighting air seeping past bleeder threads when bleeding)

3. I replaced and bled new calipers one-by-one, following the official service manual sequence (Front Left , Front Right, Rear Right, Rear Left)

I guess I answered my original question of this thread - replace and bleed one-by-one in the correct sequence. Doing it any other way won't make sense.
