Brake Pads and Rotors - Front

Replace front brake pads and rotors on a 2005 Dodge Viper, including caliper removal, rotor replacement, and proper torque specifications for this high-performance braking system.

Warnings

Tools required

Parts

• Front brake pads × 1 — Use OEM or high-performance specification
• Front brake rotors × 2 — Use OEM or high-performance specification
• Caliper slide pin boots (if damaged) × 1 — Inspect during service
• Brake hardware kit (anti-rattle clips, shims) × 1 — Usually included with pad set

Fluids

• DOT 4 brake fluid — 0.25 qt

Preparation

1. Park vehicle on level, solid ground. Place transmission in first gear (manual) or Park (automatic).
2. Place wheel chocks behind rear wheels.
3. Open hood and locate brake fluid reservoir. Check fluid level and mark current level. If near MAX line, remove small amount with turkey baster to prevent overflow when compressing pistons.
4. Loosen front wheel lug nuts 1/4 turn while wheels are still on ground.
5. Lift front of vehicle with floor jack at manufacturer-specified lift point and secure on jack stands at designated jacking points.
6. Remove front wheels completely and set aside.

Procedure

1. 1

   Inspect brake system and clean caliper area
   Visually inspect brake caliper, brake line, and rotor for damage, excessive corrosion, or fluid leaks. Spray brake cleaner liberally on caliper, rotor, and pad area. Wipe clean with rags. Do not use compressed air to blow brake dust.
2. 2

   Remove caliper slide pin bolts
   This vehicle uses Brembo fixed-mount opposed-piston calipers, which do NOT have slide pins. Do not attempt to locate or remove slide pin bolts. Instead, the caliper is retained by mounting bolts that secure it directly to the steering knuckle/bracket. Verify caliper type before proceeding.
3. 3

   Remove caliper from bracket
   After removing the caliper mounting bolts, lift the fixed caliper straight off the rotor. Do NOT disconnect the brake hose. Immediately support the caliper by hanging it from the suspension or frame using a caliper hanger or sturdy mechanic's wire. Ensure no tension is placed on the brake hose.
4. 4

   Remove old brake pads and hardware
   Remove the pad retaining pin/clip and slide the old brake pads out of the fixed caliper body. Note the orientation and position of any anti-rattle clips, shims, or pad hardware. Remove and discard old hardware clips. Clean the pad contact points on the caliper bracket with a wire brush and brake cleaner.
5. 5

   Remove caliper bracket bolts
   Locate the two caliper mounting bolts that secure the fixed caliper directly to the steering knuckle. Confirm the head size against the factory service manual before selecting a socket. Remove both mounting bolts completely and lift the caliper off.

6. 6

   Remove rotor
   Pull the rotor straight off the hub. If rotor is stuck due to corrosion, tap gently with a rubber mallet on the rotor face (not the friction surface) or use the threaded holes (if present) to press it off with bolts. Clean the hub face thoroughly with a wire brush to remove all rust and debris.
7. 7

   Prepare hub and install new rotor
   Spray brake cleaner on the hub face and wipe clean. If new rotors have a protective coating, remove it completely with brake cleaner. Place new rotor onto hub, ensuring it seats flat against the hub face. If rotor has directional cooling vanes, the rotor is side-specific (left/right). Verify correct orientation using the manufacturer's directional arrow/marking so the vanes sweep outward as the wheel rotates forward, and confirm you are installing the correct left or right rotor on each side.
8. 8

   Reinstall caliper bracket
   Position the caliper bracket onto the steering knuckle. Verify whether the factory service manual specifies thread locker for the caliper mounting bolts; use only the specified type. Install both bolts and hand-tighten. Using a torque wrench, tighten the caliper mounting bolts to the FSM-specified torque value in an alternating pattern.

9. 9

   Install new brake pad hardware and pads
   Install new anti-rattle clips and hardware onto the caliper bracket according to the kit instructions. Apply a thin layer of silicone brake grease to the pad backing plate contact points (where pads touch bracket) and to the pad ears. Install new brake pads into the caliper bracket, ensuring they are properly seated in the hardware clips.
10. 10

    Compress caliper piston
    Using a wide flat pad spreader tool, carefully and evenly retract the opposed pistons back into the caliper bores. Spread pressure across both sides of the fixed caliper so pistons retract evenly. Compress slowly and watch the brake fluid reservoir to ensure it does not overflow. This step is necessary to accommodate the thickness of the new pads. Position the clamp against the back of the caliper body and against an old brake pad placed on the piston face to distribute pressure evenly. Compress slowly and watch the brake fluid reservoir to ensure it does not overflow. This step is necessary to accommodate the thickness of the new pads.
11. 11

    Inspect and lubricate slide pins
    This vehicle's fixed Brembo caliper has no slide pins to service. Instead, inspect the pad retaining pin and anti-rattle spring for wear and replace if damaged. Clean the caliper pad abutment surfaces before reinstalling pads.
12. 12

    Reinstall caliper
    Install the new pads into the fixed caliper and secure with the pad retaining pin/clip. Remove the caliper from its hanging position and position it over the rotor. Install both caliper mounting bolts and hand-tighten. Using a torque wrench, tighten the caliper mounting bolts to specification per the factory service manual.

    Reinstall wheel and lower vehicle
    Mount the wheel onto the hub, aligning the lug holes. Install all lug nuts and hand-tighten in a star pattern. Lower the vehicle until the tire just touches the ground but still allows wheel rotation. Using a torque wrench, tighten lug nuts to specification in a star pattern. Fully lower vehicle and remove jack stands. Perform final lug nut torque verification in star pattern.

    Repeat for opposite side
    Repeat steps 1-13 for the opposite front wheel to replace the second rotor and pad set.
15. 15

    Restore brake pedal and check fluid
    Before moving the vehicle, sit in the driver's seat and slowly pump the brake pedal several times until it becomes firm. The first few pumps will feel soft as the pistons extend to contact the new pads. Check the brake fluid reservoir and add brake fluid of the type specified on the reservoir cap / in the factory service manual as needed to bring level to MAX line. Inspect under the vehicle for any signs of fluid leaks.

Reassembly

1. Installation follows removal in reverse order with the following critical notes:
2. Always use thread locker on caliper bracket bolts as specified.
3. Always apply silicone brake grease to slide pins and pad contact points.
4. Never reuse old brake hardware; always install new clips and shims.
5. Verify all torque specifications are met before test driving.

Verification

• With engine off, pump brake pedal several times. Pedal should become firm and hold steady pressure. If pedal sinks slowly or feels spongy, air may be in the system and bleeding may be required.
• Start engine and verify brake warning light is off on instrument cluster.
• Perform a low-speed test drive in a safe area. Test brakes at 5-10 mph to verify proper operation before highway speeds.
• During initial test drive, expect reduced braking performance and possible noise as pads and rotors mate. Avoid hard braking for the first 50-100 miles.
• After test drive, re-torque all lug nuts to specification with a torque wrench.
• Check brake fluid level again after test drive; top off if necessary.
• Follow pad manufacturer's bedding-in procedure for optimal performance (typically consists of a series of moderate stops from 40-50 mph without coming to a complete stop).
• Inspect for any fluid leaks around caliper and brake lines after first drive.
• Be aware that braking performance will improve significantly after proper bedding-in is complete.
