LrC, desktop version, unlike PS, does not allow for the choice of multiple types of brushes. LrC has one brush, called the Adjustment Brush, that is used to create local processing edits. The software comes loaded with a few adjustment brush presets and allows the user to create their own adjustment brush presets (click on the wording across from Effect in the adjustment panel), but does not allow the user to create different types of brushes as PS does. A preset is created by using specific adjustment levers in any way you want and then saving them to a preset that is imported into your catalog and is then found on the left side panel, under User Presets if you've selected that option, it might go there automatically, it's been awhile since I've done this. The only presets I've made are for different sharpness and tone curve settings.
