I checked the power cord and on/off switch for continuity and both were good

I also noticed a small spring protruding from one of the contact brushes
The common fix note on the website stated that one of the most common fix for my pro

Ordered the replacement brush set and installed easily.
Grinder works great
Note: I used the exploded parts diagram to figure out how to disassemble the tool
Carefully remove 1/2 of rear case at a time and replace plug in brush, to avoid having to readjust placement of trigger, springs etc. Easy on this one, had no other problems.

2) Removed motor armature

4) Removed old commutator brushes

My Bosch 1810PS 4-1/2\" Grinder stopped working. No Sound, No Movement whatsoever
1.) Unplugged unit.
2.) Using a Slotted Screwdriver or T15 Torx, I removed the (4) screws holding the two covers over power switch. I then pried the two covers apart and off the tool with a slotted screwdriver.
3.) Using a Digital Multimeter (a VOM or Continuity Tester will work also) I checked for continuity thru both wires i
... Read moren the power cord one at a time from the plug prongs to the power switch. I made sure to wiggle the power cord while checking continuity. I had continuity thru both wires.
4.) Next using the Multimeter I did the same continuity check for both poles of the power switch, one pole at a time. This also checked out OK.
5.) Next using a small Slotted Screwdriver I released the spring holding tension on one brush in its holder. I pulled the brush out while leaving its braided wire still connected to its terminal.
6.) The brush still appeared to have some life left in it by its size, but there was a black plastic pin sticking out of the brush face. Bosch has incorporated a spring loaded plastic tipped plunger into the back of the brush and this plunger is exposed when the brush wears down to a certain height. When the plunger is exposed the spring in the plunger lifts the brush off of the commutator so no electrical connection is made and the tool will not work. Bosch did this to save the tool from being destroyed by running the brushes down to the very end. So it appeared at this point all I needed was brushes. The commutator looked good.
7.) I also checked for continuity thru both stator coils with the multimeter. This required unplugging both brushes, one at a time. I used a small pair of needle nose pliers to unplug the brushes. The Stator Coils also checked fine.
8.) So I ordered a new pair of brushes. I installed them making sure the brush braided cable is routed correctly so as to not inhibit brush movement. I reinstalled both covers over the switch, powered up the tool, and it worked just fine.

My grinder stopped working suddenly, changing the brushes would be the most inexpensive first step.
I removed the housing on the grinder lifted up the tension springs that\'s one on each side pulled out the electrical connections lifted the old brushes out and replaced with the new ones. The grinder works fine. Before finding your web site we would buy new grinders. Thanks Again Fran F.
Remove back cover, pull spring end and place to the side if the brush holder. Remove old brushes from terminals. Install the new brushes in reverse order.
