My suggestion is to replace both front flex hoses and master cylinder if you don't know when they were replaced previously. The hoses can expand internally causing less flow on one side or the other. If you have a left nose dive, the right flex hose is bad. Right nose dive, left flex hose bad. In a lot of cases, the left can go bad before the right. I had a slight left pull on mine, the left hose was previously replaced but not the right. My master cylinder was contaminated causing brake light to be on. I replaced master cylinder, flushed lines, replaced both rear brake cylinders and all was great. BTW, gravity bleed worked well for me.
