I have a 77 Spitfire. I was bleeding the brakes the other day after
replacing a rear wheel cylinder, and when I was finished there was quite
a puddle of brake fluid under/around the Pressure differential valve.
I've had the car 1.5 years and have noticed some wetness there before,
but after bleeding it was quite a lot. I've only occasionally had to
add brake fluid and the brakes are fine with a good firm peddle. I
checked the unions into and out of the valve and they seem ok. However,
the connection for the brake warning light was practically dripping
wet. Is this common? Is there a fix without replacing the entire
valve? I've considered just bypassing the valve. It is my
understanding it doesn't do anything but tell you that you have a brake
pressure problem, which you have probably already figured out anyway.
By the way, I didn't noticed any fluid where the nut for the sensor
screws in, but the plastic was very wet.
Thanks,
Chris LeBlanc
