How can I change the brakes on my car?

Changing brakes is not a difficult job. Sounds like the two curved metal thingys are the break shoes (or linings). That is the part that is supposed to be changed. There is a leading shoe and a trailing shoe - don't get them mixed up. Like I said, not difficult, but very important that you get it right. I strongly suggest that you either get a manual for the car you are working on, or have someone who is very experienced help guide you through the first one. A mistake here can cause serious damage or injury.

The curved things are the brake shoes and the springy things are the retainers--there are also springs across the brake shoes and a cable to the emergency brake lever--on rear brakes. You can probably see for yourself it is a simple job--BUT there is more to a decent brake job. The drum must be measured and ground true (or replaced) and the adjuster mechanism and everything else must be cleaned and lubricated (not the shoes surfaces which must remain clean). Also, the brake cylinders which operate the shoes must be checked for leakage and/or replaced. The job should also include the messy cleaning and repacking of the wheel bearings.

Sounds like brake shoes on a drum system. Yes, they are supposed to come off. You'll need a new set exactly like them. Make sure to put it all back together the same way... then you have to adjust the brakes so the drum fits back in place... if in doubt, get a Chilton's manual or hire the work out.

It's one thing if a car can't go... it's another if the car can't stop!!!

yes they come off, those are your brake shoes, and are you replacing your front or rear brakes and are they drum or disc brakes?
