I've noticed under prolonged or hard braking, that the brake warning light comes on briefly.
On checking the master cylinder, I've seen it looks like fluid is weeping slightly from where the master cylinder connects with the servo?
Is there an O ring that could have deteriorated (It's the original unit), or is the whole thing fubar'd?
Also, if this is the reason the lights coming on, why would that be, there is plenty of fluid in the resevoir?
Thanks in advance for any help/advice. (Other than "get you brakes done!"
