Adobe illustrator brush tool size

Question

Hello, I am using illustrator to edit a sketch. But, this problem alwasy happens. I normally use the 3 pt round brush and set the size to about 0.15pt. Well, If i use a different brush and switch back to the normal paintbrush it would always chang it to 1 pt and I would have to make a stroke and set it back to 0.15 pt. Is there a reason why it keeps doing this?
Also, is there a way to erase without it editing the entire path? I know I am using vectors but I don't understand how to fix this.

I guess you are confusing diameter size of the calligraphic brushes with stroke weight. You change the Diameter of a calligraphic brush after double clicking the brush in the Brushes panel. You change the stroke weight of a path with or without a brush (Basic) applied to it using the Stroke panel. Both the brush Diameter and stroke Weight has combined effect on the path.
You can also increase/decrease the diameter of the Paintbrush Tool without changing the diameter of the brush currently selected in the Brushes panel with 1 pt increments by using the [ and ] keys on your keyboard.

If I understand you correctly, select the entire path (one way is clicking it with the black pointer) and press the Delete key on your keyboard. If you just created the path you can use Undo.
