Unlikely brush holders will be available for any but the premium brands. If the brushes aren't available from the manufacturer or one of the many power tool spare parts suppliers to be found online there are specialists dotted around the world that specialise in electric motor repairs who will make replacement brushes to order from a drawing or from a pattern.
They usually cost little more than off the shelf brushes.
make sure you got them mounted correctly and the brush wires on the correct brush, they are polarity sensitive. Failing that you need to re-flash the rotor with a battery, and a diode. This will re-establish the residual magnetism for rotor
There should be two brush holder screws, one on each side. Unscrew them and pull the brushes out. Replace them with new brushes, screw in the brush holder screws.
There should be a second brush. Look along the motor - you're looking for a spot where the armature (the part that rotates) is surrounded by a ring of little straight copper-colored bars. That's the "commutator" section. The brushes run against the copper bars.
Look on the outside of the plastic shell - there may be two large plastic screws, one on the outside of each shell half, right about where the commutator would be on the inside. Those are your brush holder screws; you should be able to change the brushes from OUTSIDE the tool without opening it. Some tools are built without external brush holders like that, but most have external brush holders.
If you find external brush holder screws, then track down the second brush and set it aside. It MAY be hanging from the brush holder in one of the shell halves. Unscrew both brush holders and remove them from the shell. Set them aside and reassemble the motor back into the shell. If the brushes are really short, like if they're nearly cube-shaped, then it's time to replace them. If not, try them again.
Insert one brush into each of the holes the brush holder screws came out of, and put the brush holder screws back in. Be careful not to cross-thread them. Try the tool.
If it still won't run, it's possible that an armature winding has given up the ghost and it's time to replace the tool...
I am in the business of repairing and rebuilding power tools and none of my brand name parts suppliers nor any of the sites I use to get off brand parts have your brushes available. I did find a part number 136506-02 that was replaced by part number 135948-03 but it shows it as a brush holder/brush assembly. My only suggestion is to find a tool repair center, ask if they have a stock of brushes and try to find a brush that will work in your holder. On many an occasion I have shaved the sides of brushes to make them fit into older model tools. You just have to be sure the top connector is compatable with your holder.
RE AEG PH 38 Brushes go to local hardware storeinthe miscelleanous everything aisle and look or a SKIL brush set exact size match $4.50 US cost I fixed mine today. Brush holders another issue
Brushes are not listed as a replacement part for your compressor. Not to worry because universal brushes are available at tool repair shops, hardware stores and ebay. Measure your brush and order same size or slightly larger and sand to fit. Dont worry too much about the length of brush as they can be shorter than factory and still work fine (just longer than worn brushes). Some motors have a spring pushing brush onto armature and others utilize the spring attached to brush to make contact. You can cut off wire from back of brush if needed, however if your motor needs brushes with spring attached, find close match and solder your old contact and spring to new brush. Also check for other problems because brushes should last the life of motor on your unit. Good luck
To flash the excitor circuit on a coleman ( the generator is built by generac) you need a 12 volt battery. You quickly apply 12 volts via your 120vac recepticals. NO MORE THAN ONE OR TWO SECONDS! Then check you ac voltage. Most of the time the brushes are burnt up when voltage is low. Check the brushes first. You can access them by taking the end cap off of the generator via two to four screws. The brush holder is easy to spot, two wires leading to the front of the amature. Hope this solves your problem.
