1LE Front Brakes on 89 IROC
When installing 1LE front brakes on an 89 IROC that has factory 4-wheel disc brakes, will I need to change the master cylinder and proportioning valve?

Yes. At least the prop valve. Let me get home tonight and pull the numbers out of my service manual for you so I will be correct.
