Jad - working from memory - a problem VERY similar to this was
discussed some months ago. If I recall correctly, the problem was
traced to a faulty master cylinder. When the fluid heated up, it
expanded enough to lock up the faulty master cylinder and actually
apply the brakes slightly. The way it was diagnosed (I recall) was to
disconnect one brake line at the master cylinder after the car was
hot, displaying the problem, and stopped. If brake fluid squirts
out, you know the MC is holding pressure when it should not.
I don't recall the model of the car in the original discussion,
About the stereo discussion:
It's all very well to have code cards, anti-theft codes, etc., but
the idiots who steal radios don't know about this and don't care.
They nust need $25 for something to snort.
There's one sure rule: If it's NOT there, they can't steal it.
That's why my Audi and ZX both have complete pull-out radios. In the
Audi, I can stick the radio in the trunk. In the ZX, I just shove it
back under the lip of the driver's seat, out of sight. The only
drawback to this is that over time, the contacts at the back of the
radio where it inserts into the chassis can oxidize. Cleaning is
I would say that a removable face panel is second best - because at
least they can SEE it won't work the way it is.
