Bleeding brakes ... Do I need to bleed the master cylinder ?!

[Canadian1968]

Well since I have to wait for summit to send me the rest of my exhaust kit! I only have to bleed my rear brakes to get the car rolling again.

I had the entire rear end out of the car and replaced the brakes lines from the proportion valve all the way back . The front section of master cylinder is pretty much empty . Do I need to bleed the master cylinder first or can I just start bleeding as normal

[terrible one]

I would bleed the master cylinder first, better safe than sorry and not very hard or time consuming. If you don't have bleeder tubes or old lines to make some go to the parts store and get a cheap bleeder kit, Dorman #13911 will have what you need and should be under $10
