spongy brakes suck

[love_my_s14.5]

hey so on saturday i swapped my rotors for drilled and slotted and got new pads also
that went really well except for the part where i pumped the brakes with the master cylinder reservoir cap open
so im thinking that air might have snuck into my braking system because when i yank on the parking brake my rear wheels dont lock up at all like they used to......actually they barely grab from what i can feel
and my brake pedal does feel spongy.......
my question is how do i go about this?

flush out the old stock brake fluid and replace and bleed with good quality fluid.
ate or pentosin fluids are the best commercially available, imho.

Your e-brakes are not part of the hydraulic system so air in the lines will not afect them. If you've just replaced your brakes, they may need to be bedded correctly. Bleeding your brakes with the reservior open is not a factor either. You just have to make sure you don't let the level in the reservior drop completely while bleeding otherwise you let air in. This would be a problem even if the cap was on. Just bleed your brakes correctly and the problem hould be resolved.

What C-Kwik said, emergency brakes are mechanical. Hence their name, if your hydraulic lines are cut, you can still brake.

Give it a few days and see if it gets better. If not, perhaps you need to adjust the ebrake cable, making it tighter.
