Out running errands and when leaving I noticed the brake light blinking. I do use the parking brake a lot. so I pulled it on and off a couple times, no change. The brakes feel normal. Stopped for gas and checked the fluid reservoir, its at the proper level.
Then driving home, after a couple miles the light went off. (?) When I got home it was back on again. I am thinking maybe a wonky parking brake switch. But will check the switch on the master also Is the parking brake switch a Normal Open or Normal Closed? Anyone else have this happen ? Or know of something else I should check.... |

Some master cylinder switches don't have the reset button; most do. The ones that don't are supposed to reset themselves when the pressure balance is no longer there.
There are switches with one wire connection, and ones with two. I believe that the two-pole ones are the original style. The two-pole ones work by shorting the two poles together. One wire is ground, the other goes to the warning light. So the switch shorts the wire from the light to ground. The one-pole switch grounds through its threads. So only the wire to the light needs to be plugged in. --DD |
