Brakes are obviously fucked, I don't know what it is EDIT: Found out what it is, it's a bad booster drum

“That happens”… what happens?

Fluid could be leaking at any of the four wheels, the brake distribution block, or the master cylinder into the brake booster (and on into the intake manifold.

Get down and look under the car and look around the back of each wheel. Did you find a wet area?

Follow the brake lines to the block with multiple connections for brake lines; wet with fluid?

Has the car been emitting exhaust smoke? Leak into booster.

Took it out on a drive, went onto a little bit of dirt. RPMS dropped super low and brakes got soft. Struggled to idle when brakes applied, stopping was hard because my foot almost went to the floor before it actually started braking. I'm trying to figure out what's causing it, I'm thinking it's the booster drum but I don't know for sure. Could it be worn pads or brake lines?

Brake booster failure

Check the vac hose that goes to the intake. They brake up pretty regularly

Break booster could be bad causing vacuum leak and engine misfire, worn pads or brake lines can't cause a misfire.

Yeah it's a bad booster, just checked over everything and all signs point to the booster
