My daughter’s starter motor was playing up so after she purchased the wrong one I repaired her old one
The car this is out of is a 1994 Toyota Hilux 22R engine RN85 Starter motor brushes 15.9mm x 6.9mm
OEX BRX70131 are the correct brushes but BRX40703 also fit, but a little longer.
After putting it back into the car it worked well. The starter motor must have only been using 1 brush for a while
