Bike: electric bike company model s
Age of bike: approximately 5 years or 4
Brakes: Tektro Auriga
Brake pads: p20.11
Issue: replaced old pads with new pads but new pads won't fit over rotor disc as there is not enough room. I have not ever had my brakes bled, I have never removed rear tire. Old and new pads are both p20.11.
Fix: I will try pushing in pistons but outside of this, with the above in mind, any other ideas why this is happening?
