Brake Pads and Rotors - Front

Replace front brake pads and rotors on a 2008 Dodge Viper, including caliper removal, rotor replacement, and proper bedding procedure for high-performance braking system.

Warnings

Tools required

Parts

• Front brake pad set (left and right) × 1 — Use OEM or performance equivalent rated for Viper
• Front brake rotors × 2 — OEM or equivalent, verify vented rotor specification

Fluids

• DOT 4 brake fluid — 0.5 qt

Preparation

1. Park vehicle on level, solid surface and engage parking brake firmly
2. Place wheel chocks behind rear wheels
3. Loosen front wheel lug nuts (19mm or 21mm, verify for your wheel type) approximately 1 turn while wheels are still on ground
4. Lift front of vehicle using floor jack at designated front jacking point and support securely on jack stands at the front frame rails — never work under a vehicle supported only by a jack
5. Remove front wheels completely and set aside
6. Inspect brake fluid level in master cylinder reservoir — if very low, investigate for leaks before proceeding; if near maximum, use a turkey baster or fluid pump to remove approximately 2 oz to prevent overflow when compressing caliper pistons

Procedure

1. 1

   Remove caliper slide pins
   The 2008 Viper uses fixed opposed-piston Brembo calipers, which do NOT use slide pins and do not pivot. Locate the two caliper mounting bolts that secure the caliper to the steering knuckle/bracket. Use the correct socket (verify size with service manual) to remove both mounting bolts completely so the caliper can be lifted straight off the rotor. Note the condition of the slide pin boots — if torn or damaged, they should be replaced.
2. 2

   Remove brake caliper
   Carefully lift the fixed caliper straight up and off the rotor. Do NOT let the caliper hang by the brake hose. Immediately support the caliper using wire, a bungee cord, or by resting it on a secure suspension component. Ensure no tension or stress is placed on the rubber brake hose.
3. 3

   Remove old brake pads
   Remove the pad retaining pin/clip and slide the brake pads out of the fixed caliper body. Note the orientation of any anti-rattle clips, shims, or pad wear indicators before removal. Some pads may be held by spring clips — carefully remove these. Inspect the caliper bracket for wear or damage.
4. 4

   Remove caliper bracket
   The fixed caliper mounts directly to the steering knuckle with two bolts (removed earlier); there is no separate slider bracket to remove. Confirm the exact caliper mounting bolt size and torque with the factory service manual before reassembly. Note: Remove brake caliper (fixed-caliper design has no separate slider bracket)
5. 5

   Remove old rotor
   The brake rotor should now slide off the wheel hub. If the rotor is stuck due to rust or corrosion, use gentle taps with a rubber mallet on the face of the rotor (avoid the friction surface edges) to break it free. Do not use excessive force. The 2008 Viper front rotors typically do not use retaining screws; the rotor should slide off once the caliper is removed. Verify against the service manual before assuming screws are present.
6. 6

   Clean hub surface
   Use a wire brush to clean the wheel hub mounting surface thoroughly, removing all rust, corrosion, and debris. The rotor must sit flush against the hub for proper operation. Clean the hub pilot surface (the raised center section) as well. Spray with brake cleaner and wipe clean with a lint-free cloth.
7. 7

   Install new rotor
   Remove any protective oil coating from the new rotor using brake cleaner — spray both sides thoroughly and wipe clean. Apply a thin coat of anti-seize compound to the hub pilot surface (center raised area only, not the rotor mounting face). Slide the new rotor onto the hub, ensuring it seats completely flat. If the rotor had retaining screws, install them hand-tight to hold the rotor in place during assembly.
8. 8

   Reinstall caliper bracket
   Position the caliper bracket back onto the steering knuckle. Install the 2 caliper bracket mounting bolts and hand-tighten. Torque these bolts to specification — typically 100-125 ft-lbs for Viper front calipers (exact specification not available in database; verify with service manual). These bolts are critical safety fasteners and must be properly torqued.
9. 9

   Compress caliper pistons
   Before installing new pads, retract the opposed pistons on both sides of the fixed caliper into their bores using a brake piston spreader tool or by carefully prying against the old pads. Do not use a single C-clamp as with floating calipers. Retract evenly and watch the brake fluid reservoir — if it begins to overflow, stop and remove more fluid. Watch the brake fluid reservoir — if it begins to overflow, stop and remove more fluid. Compress pistons until fully retracted.
10. 10

    Install new brake pads
    Install any anti-rattle clips or shims onto the new brake pads as configured on the old pads. Insert the new brake pads directly into the fixed caliper body and secure them with the pad retaining pin/clip. — the pad with the wear indicator (if equipped) typically goes on the inboard position. Ensure pads are properly seated in the bracket.
11. 11

    Reinstall brake caliper
    Remove the wire or support holding the caliper. Carefully position the caliper over the new brake pads and rotor, ensuring the pads align correctly within the caliper. The caliper should drop into place without forcing. Inspect the slide pin bores and apply a small amount of brake-specific silicone grease to the slide pins if they appear dry. Install the two caliper mounting bolts and torque to the factory specification (exact specification not available in database; verify with service manual — Viper fixed-caliper mounting bolts are high-torque fasteners, well above typical slide-pin values).
12. 12

    Repeat for opposite side
    Perform steps 1 through 11 on the opposite front wheel. It is critical to replace brake pads and rotors in complete axle sets to maintain balanced braking performance.
13. 13

    Reinstall wheels and lower vehicle
    Reinstall both front wheels, threading lug nuts by hand initially to avoid cross-threading. Once all lug nuts are hand-tight, torque in a star pattern to the factory specification (verify exact value with service manual — 2008 Viper is typically around 110-135 ft-lbs). Lower the vehicle from jack stands using the floor jack, then remove jack stands and lower completely to the ground. Perform a final torque check on all lug nuts with the vehicle on the ground.
14. 14

    Restore brake pedal and check fluid
    Before starting the vehicle or attempting to move it, pump the brake pedal slowly 10-15 times until firm resistance is felt. This moves the caliper pistons outward to contact the new pads. The first several pumps will feel soft or go to the floor — this is normal. Check the brake fluid level in the master cylinder reservoir and top off with fresh DOT 4 brake fluid to the MAX line if needed. Inspect around all brake connections for any signs of fluid leakage.
15. 15

    Perform bed-in procedure
    New brake pads and rotors must be properly bedded to achieve optimal performance and prevent warping or glazing. Perform 8-10 moderate stops from 40-45 mph down to 15 mph with light to moderate pedal pressure, allowing 30-60 seconds of light driving between stops for cooling. Then perform 3-4 harder stops from 50-55 mph down to 20 mph with firm pedal pressure, again allowing cooling time between stops. Do NOT come to a complete stop and hold the brakes immediately after a hard stop — this can cause pad material transfer and warping. After bedding, avoid aggressive braking for the first 200-300 miles to allow full pad/rotor mating.

Reassembly

1. Wheel installation and torque must be performed in a star/cross pattern to ensure even seating
2. Final lug nut torque check should be performed after the vehicle has been driven 50-100 miles
3. If any brake work required opening hydraulic lines (not typical for pad/rotor replacement), the system must be bled to remove air

Verification

• With engine running, pump brake pedal — it should be firm and not sink to floor when held under pressure for 30 seconds
• Perform a low-speed test drive in a safe area — brakes should engage smoothly without pulling to one side
• Check for any unusual noises such as grinding, squealing beyond normal new-pad break-in noise, or rattling
• Inspect wheels for any signs of brake fluid leakage after test drive
• Verify brake pedal feel is firm and responsive, with consistent stopping power
• After bed-in procedure, brakes should provide smooth, powerful, and balanced stopping without vibration or pulsation
