Brake fluid warning light

Shifting Up
Hi All,

I have a brake fluid warning light that comes on intermittently - sometimes whilst braking and sometimes whilst accelerating.

I have checked the fluid level which is up to the max line.
The front pads are getting a bit low and will need replacing soon - could this be the cause?

I have done a forum search for this topic but all I can find is somebody recommending squirting WD40 down the back of the connector - any idea what and where this is?

Look forward to receiving your replies.
Reece.

From what I remember about the P38 pad sensors, when they contact, the light stays on, they have been a swine to turn off.

I have had a couple of cars that show the light on and it was a sunken float.

Have you taken the cap off and had a look?

Thanks Chris,

I have had a look at the cap and can only see what appears to be a pressure switch encased in rubber with a slit in the center on the underneath of the cap.

If the pads were down to the sensors, would this activate the "Low brake fluid" warning message?

I assume the float would be in the container and not the cap ??

The float is on the cap.
You can either jury-rig it so the light goes off, or replace the float thingy. Be reminded that it does serve a purpose, letting you know if you have brake fluid, so for safety's sake, best to replace the cap and float assembly.
