Brakes acting funny Options

[Malhar95]

You know when u replace pads and u press the brakes to bring back the pressure in the brakes.
Like the first Time the pedal depresses wayy to much and the next time it's better

Well I noticed my car did that yest. For the first time (I didn't replace pads just did it randomly while driving)
It's doing it after every other stop. Example:
I get out of my house driveway, i press the brake at the stop sign, it depresses too much, I let go and pump it again its normal. Does it again when in getting out of the neighborhood.
Does NOT do it at the light, but at the next light after that. And it continues this way


Also noticed in an empty lot, when the pedal is depressed too much, and I kept pushing it, it locked only driver side
I have drums in the back and calipers in the front


Could It be bad fluid or does it sound like the caliper itself? The fluids not low it's b/w min and max
But does look kinda dark, but I've seen worse

Did you bleed your brakes after changing them? Sounds like you may have some air pockets in your brake lines. You should never have to change your brake fluid unless it get contaminated, its only there to create pressure to close the calipers.
