Question about 2003 Chevrolet Silverado 2500HD
Change the brake light switch this is your problem for the brake lights ,the speedo and the gearchange are different problem and i would suspect the speedo pick up sensor its on top of the diff output drive shaft passenger side .Providing that its normal wiring and not a CAN bus line because if it is then it could be a parallel resistor playing up which would knock out more that one thing but i have no product knowledge of this american vehicle .sorry
