Brushes are the contacts feeding current into a spinning armature. They wear down by design, and a motor that has lost its punch has often simply worn its brushes rather than failed.
The symptoms creep up on you. Slower spin-up, more sparking, a motor running hotter than it used to for the same work. New brushes cost a fraction of the motor around them.
It is a fiddly job rather than a difficult one, and it is worth doing before condemning a motor that has otherwise been reliable.

Good to know before you buy
Compare them against the brushes you take out before ordering. Brush dimensions vary between motor manufacturers, so a set that drops straight into an SHS motor is not guaranteed to suit something else.
Frequently asked questions
Which motors do these fit?
Our supplier does not specify. They are SHS brushes, so an SHS motor is the safest assumption. For anything else, measure the old ones first.
How do I know mine are worn?
Reduced power, more visible sparking through the vents, and a motor running hotter than it used to. Pulling the end cap and looking is the certain way.
How many are in the set?
Our supplier lists it as a set without giving a count, so we are not going to state one. Ask before ordering if it matters.
