Brake Light On problems of the 2000 Chevrolet S10

My abs and emergency brake lights have been on ever sense I have bought the truck (mid 2014) and I can't seem to figure out why. I have read several places that say that some of the solder points in the abs module have probably cracked and need to be repaired if it throws a certain code (and mine does). Haven't had the time or money to fix the problem as my truck is my daily driver. Have noticed some slight pulsing in the brakes when stopping, but not enough to annoy you. The lights on the dash will annoy you though. I have also been chasing several vaccum leaks. One was by the brake master cylinder and another (from inside the cab) sounds like it's right above the transmission housing at the back of the engine (where you can't see). It's so bad that when I first start the engine and start to drive at 1/2 throttle, it has absolutely no power, but then picks back up again after about a 1/4 mile with no power. Because of the vaccum leak, I'm guessing, it sounds like I have a turbo on the truck from inside the cab. If you turn the radio off, you can definitely hear it.

Applied brakes 200+ feet from stop sign. Road surface was bumpy. Abs malfunctioned and gave no braking. Stopped vehicle with hand brake with slight overshoot of stop line. Removed fuse from abs unit and have driven since with manual braking ignoring dash warning lights indicating that abs wasn't working. This was a problem noticed prior to this incident and occurred only when brakes were applied on bumpy surfaces.

Abs brake light illuminated, indicating a malfunction within the system. When applying the brakes, pedal wentto the floor, causing extended stopping distance. Emergency brake light also flickers.

While driving on highway at 75mph anti-lock brake light came on and stayed on until vehicle was turned off. Contacted dealer, and they have contacted the manufacturer. Part has been replaced once, but still continues.
