2009 Frontier XE 4cyl MANUAL
Am at a dead end with my 09 4 banger 5 spd. Replaced front caliper+pads. Bled brakes, rfront then lfront. Petal went to the floor. Never came up. OK, I had a new master cylinder on the shelf and changed that. Primed the MC as always to get the air out. Installed it, and still no pedal pressure? So, bled all the brakes, Rrear, Lreat, Rfront, Lfront. Petal is not coming up. Just what is up? Do I have a bad MC? Its RockAuto. Never had issues with RA. Is there an issue with the rod that goes into the vacuum assist? No vacuum would cause hard petal so its not that. That the hell?
