The brake warning light on my 81 300D has started randomly blinking in the last few days. Two things to be aware of here- I changed my front shocks a week or two ago, and noticed one of the brake sensor lines was broken in half. Also, I just found out my vac pump check valve was broken, so I pulled it out, removed it's guts and put it back in. Waiting on a new one. I'm hoping that the sensor wire is what's causing the problem, but it's starting to seem like it will blind 4 or 5 times and then stop for a few seconds, then start again, where at first it was like it was random as if the sensor line was shorting. Even now, when I'm going down the highway, or up a hill, the light either fades or goes out completely. Anybody have any experience with this?
It's in the teens with a bad wind here, so I'd like to know what's what before I go out there and tear into it. Thanks, guys.
