How to change a brush stroke after it's been made?

Is there any way to change the settings of a brush stroke on a clone or heal layer after you've made the stroke?

  You can delete it and re-draw.
  
  You can erase it and re-draw.
  
  If you want it to be stronger either paint over it again or increase the opacity and paint over it again if required.
  
  Ditto erasing partially using the brush settings to provide control.
  
  You can change the overall opacity relating to the mask area.
  
  But if you want change other parameters then no, you cant. You end up with a section of mask painted on the 'canvas' - an approach that means it is more akin to painting than engineering. the mask is a complete entity not a collection of parametrised brush strokes for which the parameters for each stroke can be adjusted post application.

  Thanks for the info.
  
  As you can still move both target and source after a stroke has been made, it seems strange that you can't change other parameters.

  Target and source are positional data for the mask not parameters for how it was created.
  
  But think about it - you have a brush stroke at low opacity with multiple passes possible.
  
  What parameters would you expect to be modifiable with any chance of success at achieving whatever result you want to achieve?

  I see what you mean. One case in which it would be useful if you could modify parameters after making a stroke, would be when you use a single circle – a click, that is, rather than a stroke – for instance to get rid of a spot that the spot removal tool can't handle. Instead of having to erase a stroke that didn't erase the spot properly and try again with different parameters, it would be easier to adjust the stroke parameters until the spot was gone – while seeing what happens when you change the parameters.

  Once you move away from the dust and spot special tools if you are trying to fix something by cloning or healing there's probably not too much you can usefully adjust in the parameters. A partial view might be to change the overall opacity of the mask to see what appears or disappears.
  
  I think it is more likely that you would benefit for editing the mask rather than adjusting parameters.
  
  Or simply suggest an enhancement that delivers a different king of processing for the adjustment rather than seek to manipulate too much in the masks. You soon get pretty close to suggesting an excursion to a pixel processing application like PS or Affinity.
