I’m trying to take off my rear rotor on passenger side. I took off the screw that holds them in and they move a little bit but don’t come out. I’ve hit it with hammer, I’ve put the 2 8mm bolts in the center holes and they the rotors go father out but don’t come out. I’m guessing the parking brake is holding it stuck. How can remove my rotors or adjust the parking brake?

 

Use longer M8 bolts?

There's an adjuster on one of the cables. If you find you need to loosen the pull rod, put match marks on the driveshaft flanges before you remove it so that it get re-installed in the same orientation.

 

Don't mess with the foot pedal it never needs adjusting (unless someone messed with it). Remove the inspection plug on the rotor and rotate the adjuster to back off the parking brake shoes as much as possible. If the rotor still won't come off use your bolts to put tension on the rotor then hit rotor with a hammer. This is what you're dealing with

Thats what i was planning on doing tomorrow. I need to go to Autozone to get a special tool for that

 

Flat blade screwdriver does the job.

 

Yes.. Use a good flashlight and adjust the coggwheel shaped thread adjuster to loosen the brake shoes from the drum.
You mey need to adjust it several full turns. Many clicks.
Prepare to replace the parking brake stuff. Buy the brake pads and the accsesories stuff. There is a locking C washer that I reuse since I am very careful with it.
Lubricate the brake wire. Those often need that or worst case being replaced.

 

the rear are drum brakes inside the rear rotor hats, so first make sure the parking brake is off.

then you need to access the shoe adjusting screw (cog) inside the service cover hole on the rotor; turn the rotor so the hole is at the 6-oclock position as shown below and remove the rubber dust boot in lower right.
