Hey guys, wondering if you can help. My Brake light on the dash came on yesterday and then shut off after a few mins of driving. Didn't really think anything of it since it didn't come back on after 250 mi of driving. Then today, right when I turned the car on, the same thing happend. Drove for about 5 mins on the way to work and then it shut off. I looked at all the brakes, no calipers are frozen. BTW, I have an 01 CL-S. Any ideas would be greatly appreciated. Thanks.

 

Check the level of brake fluid.

 

good call, will do

 

Also, have you checked your brake lights lately? Probably not it but might as well double check.

 

Are you talking about the Brake Lamp light?

 

If the level is fine, you may need a new sensor/cap.

 

I could be wrong but I thought there was a seal in the brake master cylinder that can sometimes go bad and cause an issue with the brake light to come on. Usually it is related to brake fluid but sometimes it could be this or the sensor.

 

Now that you mention this, I believe I have read about it as well.

 

hmmm...how would one check on this seal? My light has been on for a couple months.

 

LOL phipark. Yeah mine went off and hasn't come back on. I haven't checked the brake fluid yet, but its most likely that. I really hope its not the brake master cylinder seal. I've spend enough on the water pump, timing belt, plugs, power steering pump and brakes in the last few months. Oh and I did check my brake lights in the rear, they are all working. Not to sound stupid, but where would the brake fluid be? Never had to check it before. Thanks.

 

The resevoir is against the firewall on the driver's side. It will say something about "use only DOT 4 brake fluid" on the top of the cap.

 

I can't remember exactly where it is, but I believe it is easily replaced. I think it is right there when you take off the cap. It is a rubber o-ring. I'm sorry I don't have more info but my brake light used to come on once in a while and the problem was resolved once replacing that seal. It was something related to that seal there. I will try to do a little more research to find out if I can.

 

Thanks, Josh.

I just searched a little bit. It seems that there is some kind of screen/filter/seal in the resevoir that may need to be replaced. Where did you get the seal thing at? I would like to get this done at the same time I'm installing my brake lines and flushing the system.

 

It's item #10.



Now keep in mind this may not be your issue but as I recall it resolved the issues for my old CL-S. Also, the seal is about $7-$8 from Acura.
