I have a 1987 LX 5.0 that I did the 5 lug conversion on w sn95 front discs. Still running rear drums. I recently swapped to the Cobra brake booster and now I have very low brake pressure. I didn’t swap the master cylinder. Was told I didn’t need to unless I went to rear discs as well. I have bled all the lines and the master cylinder. Still no real pressure. I’ve since plugged the line going into the booster and the brakes are actually better this way. Do I need to swap to a Cobra master cylinder or am I missing something else ? Thank you all in advance.
