D35 Torpedo Posted December 28, 2023 Report Share Posted December 28, 2023 Crack lines and bleed at various points heading to the front and rear. Maybe the soft lines have collapsed. Quote Link to comment Share on other sites More sharing options...

48ply1stcar Posted December 30, 2023 Report Share Posted December 30, 2023 I bench bled my 48 in the car with the floor removed. I was installing front disc brakes and needed to bench bled before I was able to bled the front brakes. I removed the brake lines inserted brass plugs and slowly filled the master cylinder letting the air to escape. Quote Link to comment Share on other sites More sharing options...
