I put in new pads and discovered a system and rotted tubing.
What is it?
I lost pedal and I did not touch the hydraulics so I could not explain the loss of fluid. fluid. I eventually found the rusted line and a whole lot of tubing along with some kind of controller under the air filter. I would like to know what it does.


and I wnat to know if it could br done away with . There is a lot of tubing that should be upgraded.





And can it be thrown away?

Thanks'
