Machanical replacing brakes and rotors on rear of 2002 dodge caravan and cant get the rotors off.

There is no normal as I don't know what the car is used for and how heavy the loads are and how hard you brake

have the rotors check for thickness and new brake pads installed the rotors are warped

Sounds like you need some brake service. I would take your pads off and check them replace if necessary, check rotors and replace if needed, check calipers and replace if needed. If this is a drum set check shoes, and drum, and wheel cylinders. Bleed system.

I am pretty sure you are trying to remove the rear rotor, correct?

The rear rotor also has the e-brake shoes that are on the back side. The rotor is hung up on the shoes of the e-brake. Try tapping the side of the hat of the rotor with a hammer while you pull. this will often release the grip that the ebrake shoes have on the hat of the rotor.

stupid question, do you have the emergency brake on?
they normally slide off easily

In this tutorial, we learn how to check the brake pads on a 2008 Dodge Caravan, check the thickness of the brake pads on the car to see if they are thick enough. The rear pad is surrounded by a gold piece called the "shoe" and the rotor. The front pad has to be inspected by laying on your back and looking for the pad to see how thick it is. If the thickness is not enough, you need to replace it as soon as possible. Make sure the brake pads are up to t

For Disc Brakes...simply use a 7mm allen wrench to remove the 2 bolts from the inside of the caliper and use a large C-clamp to put pressure on the hydrolic piston. The two pads slide right off for replacement. Reverse directions to install new ones.

Sure sounds like you need new brake pads. On the brake pad is a small metal tab that contacts the rotor and squeals when the pads need to be changed. Hope this helps. Please keep me posted. Good luck

sounds to me if you replaced all of that than the power booster is sticking
