on my 90 240 the brake light just started coming on. It happens while Im driving and it doesnt really feel like the hand brake is engaging. Do I just need more brake fluid? To be honest I havent checked yet. Any advice as always is greatly appreciated.

There will be a test: &nbsp;<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/wink.gif" border="0" valign="absmiddle" alt=';)'> &nbsp;
Okay - brakes operate off of a closed hydraulic system. &nbsp;Closed = no fluid use/loss. &nbsp;Brakes work by hydraulic fluid pushing your pads against your rotors. &nbsp;Excess hydraulic fluid is stored in the resevoir. &nbsp;When the fluid level in the resevoir becomes low, your brake light turns on. &nbsp;Over time, the pads will wear down from the friction and require replacement. &nbsp;When the pads wear down, the hydraulic fluid has to travel a greater distance to push the now smaller pads against the rotors. &nbsp;That greater distance means it takes more hydraulic fluid from the resevoir to fill the lines to push the pads.

Q: &nbsp;If the brakes are a closed hydraulic system and the light is on, signaling low fluid level - what is the cause? <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/eh.gif" border="0" valign="absmiddle" alt=':eh:'>

BTW: you should NEVER add brake fluid unless you are bleeding.

You could check the stop light switch that is connected to your brake pedal. &nbsp;It may be that when the brake pedal is depressed it is not pressing in the switch to open the circuit. &nbsp;I had a similar problem. &nbsp;All I had to do was tighten the bolt around the switch to give it a little less movement and then everything was good <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>

Good luck,

You need brake pads.. I had mine coming on, I checked the front pads and they were worn down... I put new ones on, bled the brakes, and put in fluid and the light went off.

Ditto what BboyOxygen said. I had the same thing, on again off again brake light. So I did my brakes and bye bye light.

I'm with Kerv, &nbsp;check the brake light switch first. &nbsp;You might only need to tighten a bolt.

most likely you are low on brake fluid, nothing major.. my car has done it a few times.
