Bad vibrations

[Plum Ranger XLT]

I will take my truck back to the shop this Saturday where I had my front brakes done to tell them my problem, but anyway, I had my front brakes replaced last Friday and I developed a vibration when I apply the brakes above 40 mph. I was curious what it could be before I take it in this Saturday?

How many miles are on your truck? I'm going to go out on a limb and say you probably need to replace your front shocks.

I say this because when you brake, your nose "dives" due to weight transfer from the rear to the front.

Also, have your tires/wheels checked for balance and for being out-of-round. If you have steelies for wheels, it could be that just bumps in the road can cause your brakes to vibrate when you try to come to a stop.

Also, have your suspension and steering linkages checked for looseness. If your tie-rods or bushings aren't tight, they can cause vibrations. As you haven't had issues just driving down the road and have vibrations, your wheels, I'm assuming they are in balance and not causing your problem.
