Adjusting the front break

NONO NO NO!!

First off, tell us which brakes u did, and 2nd, do u mean pedal feels spongy or it goes straight to the floor?

If u did rear brakes and oil came out of the brake cylinders, then u need to bleed the system.

2nd cause, maybe u broke a brake line. make sure ur brake fluid is full and pump the pedal quite a few times, then recheck fluid level.

There is no rear brake adjustment valve, it's a manual ABS system that works terribly bad, and no, u do not get most of ur brake feel from rear brakes. Front brakes are 70% and rear 30% on average.

NEVER TELL PEOPLE TO PLAY WITH THEIR BRAKES IF U DON"T KNOW WUT UR TALKING ABOUT!!!!!

Brakes are a serious thing, could get someone killed for god's sakes.

Did you change the front, back or both. if it was just the front then you need to put new back brakes in because that's were most of your brake pedal feel comes from. if it was both i would start looking at your brake system to see were the rear brake adjustment valve is and then start fiddling with it till it feels better.
