might be worth pming supramat2000 off here thinks thats his username he seems to know a lot about these

 

Do you mean brake LIGHTS or the actual brakes themselves, bit confused.
Assuming it's the lights, then do a check by bridging the two wires together that go to the switch, if the lights work the switch is duff, if not then need to do a resistance/continuity test on the wire that goes from the switch to the rear brake lights, but yes as friend said if needed can replace the wire to sort out, though much more likely to be a connection problem.
This assume both bulbs are ok ?

yer proberly will have to get it sorted its got a small block chevy in now not a 29 but that would not affecet the brake wires would it its only happened sinnce its been stood for a week a wonder if its the damp

 

Probably a dicky connection on the switch, I had a problem with my dads xr4i just after fitting tvr lump, every time brakes were used it blew the fuse, checked all the usual no shorts in sight anywhere, it was the ducting pipe we used that needed to run around and near the brake switch that was shorting it as the pedal was pressed, as it was a foil pipe, still easy fix!!
