lately, more times than none, my parking brake light will come on and stay on for the duration of a trip. I'd say this happens about 75% of the time. Any ideas on what I need to do to solve this?

I'm with the two above. More likely than not your brake fluid is low.

?????




I'm parked on a bit of an incline, but you can somewhat see the level of my fluid. When I'm parked level, it's slightly above Max. I would assume that the level indication sensor is the one on the side of the reserviour?

Attached to the parking brake pedal is an electrical switch. Check that its wire is still attached and check that the metal "sensor" is not out of position.

Hmmmm, now that you mention it, I was doing alot of messing around down there, running the 16 ga. spkr wire through the door gasket. It was a real PITA getting arounf the parking brake bracket. I'll have to double-check my work down there.

Thanks for the advice, lostwrench

Did you actually open up the brake fluid reservoir and check the level that way? I know before I flushed out my brake fluid with my last brake change the level wasn't accurately readable without opening it.

Yup...the brake fluid reservoir has a tendency of getting stained over time.

Yeah, I cracked her opened and gave it a visual inspection. I'm leaning more towards it being the switch by the parking brake lever itself. Going to give that an inspection now Wink

EDIT:

Well, checked out the microswitch by the parking brake pedal. Strangly enough, I would assume it's a NC circuit. So, I disconnected the single-wire lead on the switch, and the light remained on. Double-checking my work, I also used a test lead to short out the two contacters on the micro switch, and the light also remained on.

Hmmmmmmmmm. I assumed the fault indicator lamp was a direct circuit to the parking brake microswitch? Guess not.

It's not a parking brake indicator... it's a brake indicator... it also illuminates for problems in the brake system (fluid level, etc)

Ok. I was to the assumption that all the amber indicators were the faults, and the red brake was just a courtesy indicator. Thx. Smile
