Old at driving old at maintenance on the DIY side. Enjoying the 17 Forester and at 60k no major problems, that is until today when I decided it was time to do a brake fluid change. I know the bleeding sequence so I got set up to start on the RF. When I suctioned out the front reservoir chamber I thought all was going well, it was to that point but just how the heck does one get the fluid out of the rear chamber without using a Mighty Vac and remove it by bleeding the entire rear chamber system ? I like to start with fresh in the reservoir no matter what vehicle I do, 2 3 or 4 wheels. TIA the oldowner
