Can someone please tell me how the rear rotors come off?

Mine are stuck on and don't slide off like the front rotors.

I understand there is a special tool to compress the caliper piston too.

Anyone know if this is a dealer item, or can it be purchased aftermarket?

Thank you.

 

INSTALLATION


NOTE: Perform Step #1 through Step #7 on each side of vehicle to complete pad set installation, then proceed to Step #8 .

CAUTION: Anytime the brake rotor or brake pads are being replaced, the rear caliper piston must be seated (bottomed) to compensate for the new brake rotor or lining. Because the parking brake self-adjuster mechanism is attached to the piston, a special seating method is required. The only acceptable method is by rotating the piston back into the bore using Retractor, Special Tool 8807, as described below. Any other seating method will damage the self-adjuster mechanism.




1. If necessary, seat (bottom) the caliper piston in the bore as follows: a. Assemble a 3/8 in. drive ratchet handle and an extension.
b. Insert the extension through Special Tool 8807–1 .
c. Place Special Tool 8807–2 on the end of the extension.
d. Insert lugs on Special Tool 8807–2 into notches in face of caliper piston.
e. Thread the screw drive on 8807–1 down until it contacts the top of 8807–2 which is against the caliper piston. Do not over tighten the screw-drive. Damage to the piston can occur.
f. Turn 8807–2 with the ratchet, rotating the piston in a clockwise direction until fully seated (bottomed) in the bore. It may be necessary to turn 8807–1 with 8807–2 to start the process of piston retraction.
2. If caliper adapter was replaced, install caliper adapter bolts (2) and tighten to 100 N-m (74 ft-lbs).
NOTE: There are two different abutment shims. If installed in wrong orientation, pads will not fit properly.

NOTE: If the brake pads have a protective paper on the rear face of the brake pad plate, it must be removed before pad installation.
3. Assure adapter abutments are free from debris or corrosion. Apply an even layer of MoparŠ Brake Lubricant or equivalent to entire area of four abutments PRIOR to shim installation. Install four new pad shims.
4. Place the brake pads in the abutment shims clipped into the disc brake caliper adapter bracket.




CAUTION: Use care when installing the caliper (2) onto the adapter bracket to avoid damaging the guide pin boots.


CAUTION: When removing or installing a caliper guide pin bolt, it is necessary to hold the guide pin stationary while turning the bolt. Hold the guide pin stationary using a wrench placed upon the pin's hex-shaped head.


5. Install the disc brake caliper (2) over the brake pads on the brake caliper adapter bracket.
6. Align the caliper guide pin bolt holes with the adapter bracket. Install the upper and lower caliper guide pin bolts . Tighten the guide pin bolts to 35 Nˇm (26 ft. lbs.).
7. Install tire and wheel assembly. Install and tighten wheel mounting nuts to 135 Nˇm (100 ft. lbs.).
8. Lower vehicle.
9. Pump brake pedal several times to ensure vehicle has a firm brake pedal before moving vehicle.
10. Check and adjust brake fluid level as necessary.
11. Road test vehicle and make several stops to wear off any foreign material on brakes and to seat brake pads.

 

REAR


1. Raise and support vehicle.
2. Remove wheel mounting nuts, then tire and wheel assembly.
3. Remove screw securing parking brake cable routing bracket to axle.
4. Remove two bolts securing disc brake caliper and adapter bracket to axle.
5. Remove disc brake caliper and adapter bracket from axle and rotor as an assembly. Hang assembly out of way using wire or a bungee cord. Use care not to overextend brake hose when doing this.
6. Remove any retaining clips, then slide brake rotor off hub and bearing.

You also may need to loosen the rotor from the hub bearing with a bass hammer.

 

you may have to hit the rotors with a hammer to brake them loose from the hub. There is a dealer tool for the caliper but I think any caliper tool will work so you should be able to get one at a parts store or something.

 

Thank you all for your help.

I will try again when I rotate the tires.
