Sounds like you have two separate problems, on acceleration the transmission could be slipping, check the fluid level and have a mechanic look at it. During braking, it is most likely warped rotors, which will need to be replaced to stop the shuddering. As long as the pads and shoes are in good repair, the shuddering during braking will not harm anything aside from it being annoying. The transmission can suffer serious irreplaceable damage if it is not checked out immediately.
check your swaybar links and bushings
That could be the cam shaft position sensor.Check that out>
Generally if it only shudders when braking then you likely have warped brake rotors but it could potentially be one of many other issues too.
Could be in need of a tune up. Replace spark plugs, wires, air and fuel filters.
Loose belt - will sound like a screeching noise.
Dodge Caravan was created in 1984.
The minimum thickness for the rear rotors on a 2006 Dodge Grand Caravan is 0.44 inches. When they have worn beyond this point, they must be replaced for proper braking power.
