Default 92 ZR1 Brake System Bleeding Question

I am looking to replace my master cylinder and rubber brake lines on my 92 ZR1. I know I will also need to bleed the ABS module behind the driver seat. Question: What order should I do this in? Replace master, bleed then do brake lines? Do brake lines first, bleed then do master or just do everything then bleed master and lines at the same time? I know I need to bench bleed the master first.

Thanks!

I recently replaced my brake pads and hoses. After all parts were installed, I bled the system manually per the shop manual, page 5-7 to 5-9, following the sequence (RF, RR, LR, LF) indicated without doing enything with the ABS as the fluid just goes through it. I have no problems after doing this.

Thanks, that us true regarding if you are only doing lines down stream of the ABS on a 92. I have since learned that there is a vent tube that will need to have the air removed because I am also changing out the master cylinder,

A good time to put on speed bleeders. I usually bleed the two rears then the front.

I purchased a brake cylinder cap and installed an air quick disconnect line. I put about 5 psi on the line and pressure bleed the system.
