We just replaced the rear brakes on 1993 xt225, now the brake doesnít even work. We took it off twice and tried putting it on different ways, and when pressure is applied it doesnít work. The piece inside the brake thatís supposed to turn just stays flat. The spring is tightened as much as possible, we just donít understand
I assume this means that you removed the wheel, and examined the new brake shoes. Are you sure they were the correct parts? Can you elaborate on "The piece inside the brake thatís supposed to turn just stays flat"? A photo would help.
While the wheel is off, you should be able to move the brake lever by hand to see if the cam pivots and the shoes move. Other than wrong parts or mis-assembly, there isn't much that can go wrong with a rod-operated drum brake, a technology that goes back to the stone age of motorized vehicles.
