I have a question and a rant!

I've got a leaf blower that needs new brushes. Neither Toro (the manufacturer) nor Mamco (the motor supplier) will sell the brushes to me or refer me to a third party. I got an email response from Mamco stating that they couldn't give me the specs for the brushes because it was considered proprietary info.

I thought the response was silly given that I could make the mechanical, chemical, and electrical measurements myself with the right equipment.

In addition, I thought about the car industry. Every part on every vehicle is probably proprietary to some car company or supplier. I can hear it now..."Oops, I'm sorry your headlight is bad so you'll have to buy as new car".

This company obviously wants to sell a new motor that costs more than the whole blower all because a $3 replaceable part failed. Any suggestions would be appreciated!

Thanks in advance,
Dick
