[White-V-6-S-Ten]

hey guys i just got my truck and most of the time when i stop my truck bounces a lil when the brakes are applied almost like going down a lil bumpy road..? whats the deal.... the truck rides nice and smooth cruising accelerating ect but just when the brakes are applied alos once in a while the steering wheel will make a lil noise and i can feel the wheel movin a lil it also makes a lil click but doesnt pull to one side or the other when braking if i take my hands off the wheel any ideas? maybe an easy fix?
thanks!!!!

Do a bounce test on the four corners of your truck to see if the shock are shot. Sounds to me like they may be gettin ready to go.. maybe.

how do i do a bounce test?

[Sparky2263]

If it feels like the rear is bouncing and the front is smooth, it's probably either accumulated build-up in the rear drums or out-of-round drums.

Also, is there any pulsation in the pedal?

[White-V-6-S-Ten]

No poulsation in the petal but the steering wheel will move a lil and it may be from somthing loose? or out of round on the rotors..pads... i donno.. it seems like it comes from the front and back...????????
Kinda sucks cause i havent even had the truck 2 weeks now

warped rotors?

If it were warped rotors or out of round drums you'd feel a pulsation in the pedal. I still say it's the shocks, since it happens to all corners. The bounch test is when you push up & down on the the truck 3 or 4 times & see how many bounces it takes the truck to settle.. it should settle in three bounces. Anything more than that & the shocks could be going bad. It may not be noticible enough while you're drivin around but when you brake or accelerate it changes the loads on the shocks & the problem could or will show up more.
