I have a 98 CL 3.0 with good brake pad life 3/4 thick pads. I thought i needed a brake job so i looked into taking off the front pads. I made a mistake of loosening the brake line fluid bolt on the caliper. I then started to bleed the lines from the back and front drivers side. But couldn't be able to loosen the Right front bleeder screw so i left it alone. All pads have a good life in them so i toped off the fluid level with dot3 brake fluid from all the bleeding i lost in doing so.
Few weeks later i start the car the brake light comes on. Stays off after i restart the car no light comes on. After a week, the brake light comes on periodicaly when i step on the brake pedal then when i drive it goes off.
The brakes feel fine when stoping. When i hold the brake pedal all the way down then try to press further down i get a spongy feel, sometimes the light flickers off when i do that. My thinking is i didn't bleed the entire system well. Could this be the reason the brake light turns on when the engine is cold then when warm the light turns off. So what are my options bleed entire system or live with it?

 

I would bleed all your brakes again and make sure you top off your fluid after you are done. My brake lite would come on like that and i filled up my brake fluid and it has not come one since. If they are feeling spongy then you def. have some air in there somewhere.

damnnn, same thing has been happening to me too, i have a 99 2.3 and it's been doing it lately. my brakes are fine but the light only comes on when the engine is cold and when it worms up it goes off. so you guys think i need to put some break fluid in there?

 

yes, as the brake fluid warms up it expands. our sensors are very temremental.
