crow1 Posted October 28, 2004 Share Posted October 28, 2004 The parking brake instrument light comes on and off...without the brake being applied. Is there a sensor that needs cleaning or what would be another diagnosis? thanks in advance. Quote Link to comment Share on other sites More sharing options...
silvermate Posted October 29, 2004 Share Posted October 29, 2004 you are probably low on Brake fluid......check that first and foremost....... those sensors in the resevoir are very sensitive, i had that happend b/f and it was only a 1\4 of an inch below and it triggered the light good luck Quote Link to comment Share on other sites More sharing options...
glenmore Posted October 29, 2004 Share Posted October 29, 2004 I have a similar problem. A bright parking brake light indicates your parking brake is engaged. A dimmed parking brake light indicates low brake fluid. Check the fluid ASAP. My parking brake light dims after I release the parking brake and I have checked my fluid carefully. I haven't solved this problem. From the manual it looks like it might be a switch behind the lower dash. glenmore 1990 LS400 1991 300CE Quote Link to comment Share on other sites More sharing options...

Check the fluid ASAP. My parking interesting, my light has one setting: the light is either ON or OFF.........and its the same light you might have a bad switch in there or bad wire, like you mentioned, cause i've never seen or heard of the light being brighter or dimmer indicating a different problem. <_< Quote Link to comment Share on other sites More sharing options...
markham51 Posted October 30, 2004 Share Posted October 30, 2004 The parking brake light comes on ocasionally on my 04 LS430 and did the same in my 01 LS430. I just hit the parking brake release gizmo and it goes away. It might do it 5-10 times per year. Quote Link to comment Share on other sites More sharing options...
