Guys I'm replacing both my front calipers and both front brake hose, calipers are off because of the core exchange.

Question is should it be ok to have my brake hose's off all night because it's dripping out the brake fluid and I'm in a situation now that I can't put it back together tonight, will have to do it tomorrow, as long as the brake pedal isn't hit should I be ok, or will air back up into the system once all the brake fluid leaks out?

I'm already just a 1/4 full of fluid and it's been 2 hours since it's been apart.

Friggen parts people couldn't find the other caliper in stick they showed of having, it will be in tomorrow.

 

Gravity will be your enemy. Air will not get in the line until gravity pulls all the fluid out of the master cylinder. And over night it will. Go back to parts store and get your old calipers and just screw them back on. Or just let it drain the old fluid out . You will need to bleed the brakes anyway. Also will be beneficial to get all the old fluid out and replace with new. I replace all brake fluid when i change my pads anyway.

 

Thanks, yea I'll have to bleed them anyways so looks like new fluid!

 

Trick i use to do was stick the brake line in brake fluid filled mason jars. it will counteract the effects of gravity
