the brush is a peice of carbon that is attached to the startor by a brush holder.
universal motor r mostly used for domestic purpose applicatios like the vaccum cleaner,foodprocessors and mixeshair driers,coffee grinders,electric shavers etc....another applications for blowers.
A universal motor is used to operate a food mixer.
the reason for brushes is to makethe motor revolve. The more brushes probably make a more powerful starter motor
"Induction" motors imply AC power Most AC motors do not have brushes or commutator If your motor does have brushes, a lot of sparking where the brushes meet the comutator is a good indication that it needs to be cleaned and/or "cutdown". If your motor does not have brushes, then you have more serious trouble. Need more details

A brush is made out of carbon.
Carbon
A brush is a piece of carbon attached by the brush holder to the startor. (source-page 36 of the study unit for appliance repair)
The most common use of brushes and commutators these days are in universal motors. This type of motor is used in hand tools like drills, saws, and home motor driven appliances
Carbon is much stronger and because the motor commuter is spinning copper brushes will wear off quickly.

Sparking at the brushes of a universal motor can be caused by several factors, including worn or damaged brushes, improper brush alignment, or inadequate brush pressure against the commutator. Additionally, dirt or debris on the commutator surface can lead to poor electrical contact, resulting in arcing. Excessive load on the motor or improper voltage supply may also contribute to increased sparking. Regular maintenance and inspection can help mitigate these issues.
Motor brushes ride one the commutator.
