| + | [* black] Ideally, the carbon brush should incorporate a stop (pink arrow), such that when worn out, the spring and other hard parts cannot contact and damage the commutator. The stop is formed by a groove along most of the edge of the new carbon brush and a corresponding protuberance in the brush liner (orange arrow). |
|---|---|
| + | [* black] Using a brush with a stop means that it can only be inserted into the liner in one direction ie from the back which is why the liner is removed. Another advantage of using a brush with a stop is that it wont fall out during reassembly. |
| + | [* black] Of course if there is no lug, indentation or protuberance in the liner, there is no point buying brush with a stop and a plain brush would suffice. (no significant difference in price). |
