The right nozzle behind the brake


The left nozzle behind the clutch

Hi fellow HD brothers,


I recently purchased a 2014 Project Rushmore Street Glide, it has an air suspension.


Behind the clutch is a air release valve that seems to deflate the air, however and this is where I am lost with knowledge, on the right side behind the front brake is another valve.


Can anyone please assist me with the purpose of this valve?


Thanks brothers
