Bleeding the Brakes

[ricardo381]

I'm planning to replace the brake fluid in my Legacy. Should the
engine be running during the bleeding process? Thanks!

No. You can still "stroke" the brake pedal with the engine off, it's
just harder.

Anyone know what size clear vinyl hose to fit over the bleeder valve?

I can't imagine any reason why, AFAIK they have
nothing to do with each other. I've not done that on
my Subaru but I've bled brakes on Porsches for some 30
years. Although I'd prefer having the dealer do it
because brake fluid is hygroscopic (absorbs water) and
if not done right can ruin your brake system. The
dealer or a good mechanic will also check the hoses,
etc. The money you save is a pittance compare to the
potential problems.

There are lots of article on the I'Net, e.g.,

GOOD LUCK
