Well, recently I've noticed that my truck is like shaking or pulsating when I break. I'm not to worried, as I'm doing the cognito 4-6 NTBD in 3 weeks and I'll basically rebuild the whole front end, but any thoughts as to what it could be? Wheel Bearing? Breaks? Truck has 50,000 miles.

Thanks guys

#1 cause of pulsating pedal upon breaking is warped rotors, which may be able to be turned down if they're not too worn. Most of these trucks don't have brake problems at 50K unless you run in road salt/wet conditions (which destroys caliper slides) or tow heavy alot. Get it in the air and start wiggling tires top to bottom, left to right, look for play in all joints, wheel bearings, etc.. Take a look for uneven pad wear front and rear, sticky calipers will cause rotors to heat up, rapid hot to cool warps them, as may improper wheel torque sequence or a lot of aggressive driving.
