disabled anti-theft '98 ConversionVan Econoline 159

Anytime dead battery must be re-charged, disabled anti-theft acts as if it is activated. THIS time, it is the hazard lights...they activate every time we open the door now and/or try to start the engine. The only way to start the engine is to by-pass an jump the starter from the battery.

What's up with this?

SECOND QUESTION:

After re-doing brakes, and changing calipers out two times...throbbing of the the brake peddle occurs when braking. Any suggestions?

Thanks...:1zhelp:
