My service manual says don't Bench Bleed Master Cylinder on car Where can I get the Kit to do this in my Vice. Or should I just get some Brakeline with fittings. Then make my own using some clear plastic tube Thanks
 
Most master cylinders do not come with the tube kit for bench bleeding anymore. Instead, they give you caps for the ports. Just cap them off and bench bleed as you normally would. It can be done in a vice of on the car. Just put the cap on and pump gently until all the air is removed.

I would think that would just blow the caps off and make a mess.
I have always used a bench bleeding kit, they are cheap at any auto parts store.
 
the proper way is to block the ports off and pump it in the vice, once done you should not be able to push the piston more than 1/4".

this way is more efficient than running the tubes back into the liquid
 
I think I got it. No air bubbles I didn't know fluid would shoot out of the tront Res. Hope that was normal. When I poured fluid in I started getting the air bubbles. It was easy at first to push the piston. But got harder and the air bubbles stopped. But the front res. Still shot fluid out. I'm hopeing I did this right.
 
I've never bench bled one in my life and never had trouble getting one bled in short order. To me bench bleeding just seams like your asking for a mess installing lines with fluid dripping out.
 
for some reason the wildwood ones are hard to bleed and require bench bleeding, unsure about the rest
 
I just bench bled a Wilwood mc with the kit provided. Easy and didn't drip out a drop. Kits can be bought from Summit or Jegs.
 
It also depends on the master application (drum/drum, disc/drum, or disc/disc).

Most disc/drum masters are 'two-stage'. The pistons that apply the fluid, do it at two different rates, making it two-stage. If that makes any sense. That's why the bleeding is a little harder.
