Diagnosing info:
I usually find this in YouTube videos or on auto forums, but every now and then they are written in the manuals.
If you feel a wobble (push in and out) on your brakes, then your drum is warped. If it feels mushy, then there is probably air in the fluid system that needs to be bled.




I’ve been using TizenTube since this issue came up and it’s gotten the job done. Not sure if it will be a good long term alternative.
