When you hit the brake pedal, the front disc brakes engage to stop the car but does hitting the brake pedal also engage the rear brakes? I understand that the hand brake is connected to the rear brakes. I have a 2003 Nissan Maxima.

Do the front brakes have a slack adjustor as well? I change the front pads this weekend and it seems like they would always be touching the rotor.

The master cylinder has a dual reservoir. when you hit the brakes it hydraulically activates both the front & rear brakes. The hand brake is in case of hydraulic failure & for parking (it is mechanical not hydraulic) Good luck.
No slack adjuster on disc brakes.
Disc brakes are not pulled back by springs when you release the pedal. Drum brakes use springs to retact the brake shoes because gravity & design require it to keep them from wearing out prematurely. As long as the slide & the caliper piston are working freely the disc brakes will not wear prematuely.

Sorry you bought a Nissan. All of the USA's wealth is going to the far east.
However, these systems all work the same. Pushing the brake pedal sends many pounds of fluid pressure to what's called the "slave" cylinder. In front, the pistons in the slave push the pads hard against the rotating disk. In the rear, the pistons push out, so that the round pads press outward hard against the revolving drum.
Your emergency brake probably does not depend upon the fluid pressure from the "master" cylinder. Instead, it uses a cable to pull the rear pads against the revolving metal rings (called the brake "drum"). It is designed to help stop the car, even if you have lost all fluid somehow.
If your car is old, maybe you should not use the emergency brake at all. The cable can seize inside its guide, and the rear pads won't release fully. Then drums get hot while driving, and you eventually ruin your rear pads, or "shoes."
Hope this helped a little.

The front brakes are applied the first part of the pedal such as slowing down when the the brakes are fully applied then the rear brakes are applied that's why you have either 2 brake lines coming out of the master cylinder. The one closest to the firewall is for the front brakes and the outer one is for the rear . you will usually wear out front brakes about 20,000 before the rear.

The hydraulic activity within your braking system has steel lines within 6 - 8 inch of your rear brake backing plates or disc caliper. Brake hoses connect pressure in the lines to either expand the brake shoes or squeeze the caliper pads with an internal caliper piston. Inside a rear brake drum a hydraulic wheel cylinder expands on both ends to engage the brake shoes to the brake drums. An emergency brake is always mechanically hooked to either the shoe mechanism or a mechanical lever on the rear caliper.

How Drum Brakes Work

The hand brake, when set, causes the rear brake shoes to expand through a mechanical linkage. When the brake pedal is depressed, the system is hydraulically pressurized causing the front calipers and rear brake shoes to expand.

Yes, that's why they put them there.
Without rear brakes your car would take longer to stop.
If the rear brakes do not feel as they are working, probably need adjusting. There are slack adjuster on the rear shoes. Usually there is a cut out on the backing plate to enable you to insert a screwdriver through.
Only adjust so the shoes are slightly dragging.

The front brakes do not have a slack adjuster it does appear that they would always be draging but they are not. there is a gap a couple thousands of an inch between the rotor and the brake pad the gap is so small you cannot see it and water cannot get between the rotor and the pad that is why disc brakes work fine when wet, unlike drum brakes.

I'm surprised this car doesn't have 4 wheel disc brakes.
