Last week my home vacuum cleaner broken hence I try to DIY repair, after open up the machine found out that the carbon brushes worn out. Looks like this is the cause of the break down. Try to buy carbon brushes in Petaling Jaya but not available after some searching the looks like shops selling carbon brush are located along Jalan Loke Yew. Bought mine from this shop Valee Carson & Trading Sdn Bhd at 26-7 Jalan Loke Yew. From the company web site it looks like a very modern shop once I reach the shop it just a normal trading shop. :-) I mean chinaman type.
