* Drum brakes: Drum brakes almost certainly require a spring compressor tool to safely compress the return springs holding the brake shoes in place. Trying to do this without the tool is extremely difficult, and risks damage to the springs, shoes, or even injury.
* Disc brakes: Disc brakes are less likely to require a specialized spring tool, though you might need pliers or a small hook to help manipulate some of the caliper components. However, even with disc brakes, a C-clamp might be helpful for compressing the caliper piston.
In short, while not absolutely *essential* in all cases, a spring compressor (for drum brakes) or at least some specialized pliers (for either drum or disc) will make the job significantly easier and safer on a 2001 Dakota's rear brakes. It's highly recommended to have the appropriate tools. Check a repair manual specific to your Dakota's year and model for definitive tool requirements.
