How hard of a job is this? Can someone tell me step by step how to remove it. Also how to bleed it. Thanks in advance.

 

Are you referring to the pump?

I've heard it's a tough job due to the limited amount of working space. My pump just went so I sourced one for $46 with a 6 month warranty and took it to a shop to have it installed for around $120.

So $166 total to me is better than trying to do it myself.
