Brakes are kinda weak?

So my brakes are kinda weak, and while they do not squeak on the outside, the pedal does when i push it down, and it seems weak to push, so im wondering if it is the pads, the rotors, the pedal, or what...?

PS, I clearly know nothing about cars.

PPS, My handbrake is so weak, that on a hill, fully engaged, on neutral, it still rolls. Thoughts on how to go about fixing this or what to do?

Brake pads could be about done. Also, could be your brake hoses, after a while they expand when under pressure giving you a soft pedal. I had the same problem and decided to get new calipers, rotors, ceramic pads, and new hoses, now I have a nice firm pedal.

You need to inspect your brakes , see if your pads are getting thin , how the rotors and calipers look. The slides could be sticking causing the increased effort at the pedal. It might be time for a brake job or a good service. I think that you really need to go in and clean and lubricate your slides just to keep everything operating correctly.

so the pedal has a soft feel? you have air in the lines which could mean, you have a leak. and i would point more towards a master cylinder. but definitely need to get them checked out. if you dont know cars very well, i would find a good shop.

+1 on weak flexibles. Also full clean and lub on caliper pistons, slides, pins and mounts. Handbrake adjustment is through any of the rear wheel bolt holes, although I would suggest removing one side first. This will let you see the parts and how they interact, if the shoes are too worn and genrally make a decision on how much of a service is required. If it looks good when you check the first side (I doubt it) the you need only adjust the second side as you have a picture in your minds eye of what is going on.
