Hi Etgdpu,
Can I ask if your using standard discs and pads on your buggy.
The only reason I ask is I have seen some guys use the fibreglass avid type disc and leave the actual pads on and after a while these get superhot and bind up.
If using normal discs and pads, I suggest you ensure that you have about 3mm or more play inbetween the pads and the discs. i.e back the 2 screws off for the front discs and back the 2 off for the rear.
I usually have a lot of play here and use brake punch on my tx to jump to the bite spot on brakes when I just touch brakes on tx.
