Hi,
probably an alternator, charging or battery fault. I have had this happen
occasionally, and here is my deductive reasoning (fire at will).
1) When you brake you have taken your foot off the accelerator, so the revs
drop.
2) The drop in revs causes a drop in alternator output
3) Braking causes the two high brightness (high load) brake lamps to come
on
4) The alternator and battery can no longer sustain the rest of the car's
electrical requirements, in particular the sensitive electronics in the
radio.
5) er.,
6) that's it.
Of course you could test this theory by disconnecting the brake lights or
removing the bulbs, but be very sure to reconnect them. Also, top up the
battery/ies is necessary. Use only distilled water, tap water (even
boiled) will cause the battery to deteriorate.
Hope this helps.

Well the car has been running great but today it developed a new glitch.
When
you hit the brakes the radio goes out - read out goes blank. It usually
goes
right back on even though I continue braking. Sometimes it doesn't go out
but
more often than not it does. Sometimes when it goes out it stays off for
15
or 20 seconds before coming back on. Any ideas or has anyone experienced
anything like this? As usual all help is greatly appreciated.
