DYU Brake

I bought both front and rear brake assemblies.
They came in the same parcel with NO indication which was FRONT nor which was REAR.
Nor where there any instructions included as to how to disassemble the old Brakes and how to install the new Brakes.

In fact I have searched the internet and have been unable to find any Maintenance/Replacement Instruction Manual for my eBike.

I received the breaks i ordered for on time and i am ok with the product.
