Had brakes redone about 12k ago....and also a bearing on the driveline replaced. Since then the truck has had a slight vibration....now the vibrations is more noticeable when braking......
Anyone ever experience this before and if so what will remedy the problem?
Thanks in advance for the responses!!

Sorry....didn't provide info on the truck... 99 Tacoma 4wd Ext Cab w/ v6.... Toyota....gotta love 'em!!!
My vote is warped brake rotors.
I also had brake work done, but my shaking began immediately. I bought my brake parts on eBay, and called the store to report the probkem. They shipped out another set of rotors at no charge. I took those rotors to a machine shop to have them measured for true -- or run out. This measurement involves putting the rotors on a lathe and then bringing a meausring device up to the surface -- if one does not care abut the actual measurement, you can bring the cutting tool in slowly until it just begins cutting, and note that the cutting is not uniform all of the way around the rotor.
In any case, I had rotors that were not machined true from the get-go. I paid the machine shop $35 to grind the surfaces to true. (I have cross drilled and slotted rotors, so the lathe was not the appropriate machine to use.) Most places that I know of will turn a rotor for $10 to $15.
Since your brakes are essentially new, I see no problem for you to have the rotors turned. I would not hesitate to consider this as the problem and the solution. I would not consider the bearing as part of your current problem set. If your brakes were old, approaching end life for example, then putting them on a lathe would likely cut them to below the minimum spec that is stamped on the rotors. But with new rotors, there is plenty of meat on the rotors to cut a couple of thousands off to bring them true.
Might be a warped front rotor, caused by excessive heat.
I have an 03 Taco, 58000kms. For the past few weeks I get a front vibe during medium to hard braking. I never had the brakes done, hasn't been a need. The pads have enough life left to get me to my next scheduled maintenance in the spring. Although I may try and do it myself.
sometimes the monkees in the garages will use air wrenches to install them instead of torquing the bolts to spec (or at least evenly). This can cause new rotors to "warp" pretty quick, so i understand...
most likely warped rotors, nonetheless.
The vibration while driving is probably an unbalanced front tire. When they had the wheels off for the brake job they may have dislodged a balancing weight. The vibration while braking is most likely a warped brake rotor. Take it to NTB and have them balance the tires and turn the front brake rotors. I had brand new rotors put on by Brake-O and they vibrated until I had them turned.
