Brake Caliper Bracket

Replacement of the brake caliper bracket (caliper mounting bracket) on a 2008 Dodge Viper 8.4L V10, requiring wheel removal and brake system service.

Warnings

Tools required

Parts

• Brake caliper bracket × 1 — Use OEM specification or Mopar equivalent
• Brake caliper bracket bolts (if reuse not recommended) × 2 — Use OEM specification

Fluids

• DOT 4 brake fluid — 0.25 qt

Preparation

1. Park vehicle on level surface and engage parking brake firmly
2. Loosen wheel lug nuts 1/4 turn while vehicle is on ground
3. Lift vehicle using floor jack at appropriate jacking point and secure with jack stands
4. Remove wheel completely and set aside
5. Verify correct corner of vehicle - this procedure covers one wheel position at a time

Procedure

1. 1

   Remove brake caliper from bracket
   Locate the two caliper mounting bolts securing the fixed Brembo caliper to the bracket/knuckle. Remove both caliper mounting bolts completely. Carefully lift the caliper assembly off the brake rotor and bracket. Do NOT allow the caliper to hang by the brake hose - support it using a brake caliper hanger hooked to the suspension or secure it with mechanic's wire to the spring or control arm. Ensure no tension is placed on the rubber brake hose.
2. 2

   Inspect brake line connection
   Verify whether you need to disconnect the brake fluid line from the caliper. If the caliper bracket can be accessed without removing the caliper entirely from the vehicle, leave the brake line connected and proceed. If the caliper must be completely removed due to limited access, note that the brake line banjo bolt or flare fitting will need disconnection (requires system bleeding afterward). For most Viper applications, the fixed caliper can remain suspended on the hose while the bracket is serviced; support it to avoid stress on the brake hose.
3. 3

   Remove brake pads and hardware
   With the caliper removed, note that on the fixed Brembo caliper the pads are retained in the caliper body by retaining pins and an anti-rattle spring. Remove the pad retaining pins/spring and slide the pads out of the caliper. Inspect and set aside hardware. Inspect all hardware for wear or corrosion and set aside for reinstallation or replacement. Note the orientation of all hardware for correct reassembly.
4. 4

   Remove caliper bracket bolts
   Locate the two large caliper bracket mounting bolts that secure the bracket to the steering knuckle or rear suspension hub. These require significant torque to remove. Using a breaker bar and appropriate socket, remove both bracket bolts completely. Verify the exact socket/hex size against factory service documentation before proceeding. If bolts are seized or corroded, apply penetrating oil and allow to soak before attempting removal.
5. 5

   Remove caliper bracket
   Pull the caliper bracket straight off the steering knuckle or hub mounting surface. The bracket may have some corrosion or brake dust buildup causing it to stick. Gently tap with a plastic mallet if needed, but avoid damaging the mounting surface on the knuckle or hub.
6. 6

   Clean mounting surfaces
   Using a wire brush and brake cleaner, thoroughly clean the caliper bracket mounting surface on the knuckle or hub. Remove all corrosion, brake dust, and debris. Clean the caliper bracket bolt holes and inspect threads for damage. If threads are damaged, the knuckle or hub may require thread repair or replacement before proceeding.
7. 7

   Prepare new caliper bracket
   Inspect the new caliper bracket for shipping damage or defects. Clean any protective coating if present. Do not apply anti-seize to the caliper bracket bolt threads. Follow factory guidance regarding thread preparation — these bolts may be torque-to-yield or require thread-locking compound and replacement with new bolts. Do NOT apply anti-seize to the bracket mounting face or the knuckle mounting surface - these must mate metal-to-metal.
8. 8

   Install new caliper bracket
   Position the new caliper bracket onto the knuckle or hub mounting surface, aligning the bolt holes. Insert both caliper bracket mounting bolts by hand and thread them in several turns to ensure proper thread engagement. Do not cross-thread these critical fasteners.
9. 9

   Torque caliper bracket bolts
   Using a torque wrench, tighten both caliper bracket mounting bolts in a cross pattern to the manufacturer's specification. For the 2008 Viper, the caliper bracket/mounting bolt torque must be verified against the factory service manual before tightening. Do not rely on an assumed value for this safety-critical fastener. Ensure both bolts reach the same torque value and the bracket is seated flush against the mounting surface.
10. 10

    Reinstall brake pad hardware and pads
    Install the anti-rattle clips, shims, and any other brake pad hardware onto the new caliper bracket in the same orientation as removed. Slide the brake pads into position in the bracket. If reusing old pads, ensure they are installed in the same orientation as removed (inner/outer positions matter).
11. 11

    Reinstall brake caliper
    Remove the caliper from its support wire or hanger. Carefully position the caliper over the brake pads and bracket, aligning the caliper slide pin holes with the bracket. Insert both caliper mounting bolts and hand-tighten. Torque the caliper mounting bolts to the factory-specified value, which must be verified against Viper service documentation before final tightening.
12. 12

    Reinstall wheel and lower vehicle
    Install the wheel onto the hub, ensuring proper seating. Hand-tighten all lug nuts in a star pattern. Lower the vehicle until the tire just contacts the ground (weight still on jack stands). Torque the lug nuts to the factory-specified value in a star pattern; verify the exact lug nut torque against the 2008 Viper service specification before returning to service. Fully lower the vehicle and remove jack stands.

Reassembly

1. If brake fluid lines were disconnected, bleed the brake system completely per manufacturer procedure before operating vehicle
2. Pump brake pedal multiple times to seat brake pads against rotor before moving vehicle
3. Verify firm brake pedal feel before test driving

Verification

• With engine running, pump brake pedal several times and hold - pedal should be firm and not sink
• Perform low-speed brake test (5-10 mph) in safe area to verify proper braking function before returning to normal operation
• Check for any brake fluid leaks around caliper and bracket area
• Listen for any unusual noises during brake application - squealing, grinding, or rattling may indicate improper installation
• Verify caliper bracket bolts are torqued to specification by re-checking with torque wrench
