Carbon brush qualiity ?

[sadoldgeorge]

A few months ago I replaced the brushes in my Bosch 3030 with some cheapies from Fleabay. They are now in need of replacement again..
Should I bite the bullet and fit genuine replacements for £30.00 or fit another 10 £3.00 sets over the next few years???

In the words of that tv show " The decision is yours", personally I would value my time too highly to be repeatedly doing something unnecassary, but are you sure that the com on the rotor is ok, a few months is not long even for cheapos.

The commutator looks absolutly fine, no uneveness or roughness. When running there is no more than normal contact sparking either. I reckon its just the dubious quality of the cheap brushes. I think I'll get a proper set and see how long they last. My missus is after a new machine so might just replace it when the motor packs in again...
