Brake Fluid Level Switch Test

Brake Fluid Level Switch Test

1. A Reservoir cap
2. B Down position
3. C Float (built-in magnet)
4. D Switch contacts closed when float drops
5. E Switch contacts open when fluid level correct
6. F Up position
1. Remove the reservoir cap. Check that the float moves up and down freely; if it doesn't, replace the reservoir cap assembly.
2. Check for continuity between the terminals with the float up and down.
   There should be continuity with the float down and no continuity with the float up. Replace the reservoir cap assembly, if necessary.
