Warnings

Tools required

Parts

• Rear brake rotor × 1 — Use OEM or equivalent specification
• Rotor set screws (if corroded) × 2 — M6x1.0 thread

Preparation

1. Park vehicle on a level, solid surface and engage parking brake.
2. Place wheel chocks in front of both front wheels.
3. Loosen rear wheel lug nuts 1/4 turn while wheel is on the ground, but do not remove.
4. Raise the rear of the vehicle using a floor jack at the appropriate rear jacking point.
5. Support the vehicle on jack stands placed at the manufacturer-designated support points on the side being serviced.
6. Remove the wheel lug nuts completely and remove the wheel.

Procedure

1. 1

   Inspect brake components
   With the wheel removed, visually inspect the brake caliper, rotor, and brake lines for damage, leaks, or excessive wear. Check the brake pad thickness on both sides. If pads are worn to 3mm or less, they should be replaced during this service. Note the position of the caliper and bracket assembly for reassembly reference.
2. 2

   Compress brake caliper piston
   Before removing the caliper, if the pads are being retained, back the opposed pistons off slightly to ease caliper removal over the rotor. Use a proper brake piston spreader tool to press the pistons evenly on both sides of the fixed caliper. Monitor the brake fluid reservoir to ensure it does not overflow; remove fluid if necessary using a turkey baster or fluid transfer pump. baster or fluid transfer pump.
3. 3

   Remove caliper slide pin bolts
   Locate the two caliper mounting bolts that secure the fixed opposed-piston caliper to the knuckle. Using the appropriate socket, remove both caliper mounting bolts. Keep these bolts together for reinstallation.

4. 4

   Remove and support brake caliper
   Carefully lift the brake caliper straight off the rotor after removing the two caliper mounting bolts. Do NOT disconnect the brake hose. Immediately secure the caliper using a wire hook, bungee cord, or similar support to a nearby suspension component or frame rail. Ensure there is no tension or stress on the brake hose. Do not allow the caliper to hang freely at any time.
   ⚠️Allowing the caliper to hang by the brake hose can cause internal hose damage and subsequent brake failure.
5. 5

   Remove caliper bracket
   This step does not apply to the 2005 Viper, which uses a fixed caliper bolted directly to the knuckle with no separate bracket. Proceed to rotor removal after the caliper is removed and supported.

6. 6

   Remove rotor set screws
   If present, locate the rotor set screws that secure the rotor to the hub. The Viper rear rotors typically have 2 Phillips or Torx set screws. These screws often corrode and may require penetrating oil and an impact driver to remove. If the set screws strip or break, they can be drilled out—they are not required for rotor retention once the wheel is installed.
7. 7

   Remove old brake rotor
   Pull the rotor straight off the hub. If the rotor is stuck due to corrosion, use a rubber mallet to strike the rotor face (between the bolt holes) evenly around the perimeter to break it free. Do not strike the friction surface directly if the rotor is to be reused. If the rotor will not come free, apply penetrating oil at the hub interface and allow it to soak, then retry with the mallet.
8. 8

   Clean hub mating surface
   Use a wire brush to thoroughly clean the hub face where the rotor mounts. Remove all rust, corrosion, dirt, and old brake dust. The hub surface must be clean and flat to prevent rotor runout and vibration. Wipe the surface clean with brake cleaner and a rag. Inspect the hub for damage or excessive wear.
9. 9

   Prepare and install new rotor
   Remove the new rotor from its packaging and clean both friction surfaces with brake cleaner to remove any protective coating or oil. Apply a thin coat of anti-seize compound to the hub mating surface (not the rotor friction surfaces). Slide the new rotor onto the hub, aligning the holes for the set screws and ensuring it seats flush against the hub face.
10. 10

    Install rotor set screws
    If using new or original set screws, thread them into the rotor holes and tighten to specification. These screws only need to hold the rotor during assembly; the wheel lug nuts provide the actual clamping force. Do not overtighten as this can strip the threads.
11. 11

    Reinstall caliper bracket
    Position the caliper bracket onto the spindle or axle housing, aligning the bolt holes. Thread both caliper bracket bolts in by hand first to ensure proper thread engagement. Tighten both bolts to specification using a torque wrench in a crisscross pattern.

    Reinstall brake caliper
    Remove the wire or support holding the caliper. Position the caliper over the new rotor, aligning the caliper mounting bolt holes with the knuckle. Thread both caliper mounting bolts in by hand, then tighten to specification using a torque wrench.

    Reinstall wheel
    Position the wheel onto the hub, aligning the lug nut holes. Thread all lug nuts on by hand to prevent cross-threading. Snug the lug nuts in a star pattern with a wrench, but do not torque yet.
14. 14

    Lower vehicle and torque wheel
    Remove the jack stand and carefully lower the vehicle until the wheel is in contact with the ground but not fully weighted. Using a torque wrench, tighten the lug nuts to specification in a star pattern. Fully lower the vehicle and remove the jack. Re-torque the lug nuts in a star pattern to verify proper torque.

    Pump brake pedal and check fluid
    Before moving the vehicle, sit in the driver's seat and pump the brake pedal several times until it feels firm. The first few pumps will extend the caliper pistons back against the new rotor. Check the brake fluid reservoir and top off with the brake fluid type specified in the owner's manual/reservoir cap for this vehicle if needed. The pedal should feel firm and consistent. If the pedal feels soft or goes to the floor, do not drive the vehicle—inspect for air in the system or other issues.
    ⚠️Do not attempt to drive the vehicle until the brake pedal feels firm and normal. A soft pedal indicates air in the system or another brake system problem.

Reassembly

1. Reassembly is covered in the main procedure steps above.
2. Ensure all fasteners are tightened to the specified torque values.
3. Verify the brake caliper is properly secured and not in contact with the wheel.
4. Double-check that no tools or parts were left in the wheel well.

Verification

• With the vehicle stationary, pump the brake pedal 5-10 times. The pedal should feel firm and consistent by the third pump.
• Check the brake fluid level in the reservoir. It should be between MIN and MAX marks.
• Perform a careful test drive in a safe area at low speed (under 15 mph) to verify the brakes engage smoothly without pulling, noise, or vibration.
• Perform 10-15 light brake applications from 30-40 mph to bed in the new rotor against the pads.
• After the first 50-100 miles, re-torque the wheel lug nuts to specification.
• Inspect for any fluid leaks around the caliper and brake hose connections.
• Listen for any unusual noises during braking that could indicate improper installation.
