Brake Caliper Bracket

Remove and replace the brake caliper bracket (caliper mounting bracket) on the 2005 Dodge Viper, including caliper removal, brake pad removal, and bracket reinstallation with proper torque specifications.

Warnings

Tools required

Parts

• Brake caliper bracket (caliper mounting bracket) × 1 — Use OEM specification
• Brake pads (if reusing old bracket) × 1 — Use OEM specification or performance equivalent

Fluids

• DOT 4 brake fluid — 0.25 qt

Preparation

1. Park vehicle on level, solid ground and engage parking brake.
2. Place wheel chocks behind rear wheels if working on front brakes, or front wheels if working on rear brakes.
3. Loosen wheel lug nuts 1/4 turn while vehicle is on the ground (do not remove).
4. Lift vehicle with floor jack at appropriate jacking point and secure with jack stands.
5. Remove wheel lug nuts completely and remove wheel.
6. Verify adequate working clearance around brake assembly.

Procedure

1. 1

   Remove Caliper Slide Pin Bolts
   Locate the two caliper slide pin bolts on the rear of the caliper assembly. These secure the caliper to the bracket. Using a 15mm socket or wrench, remove both slide pin bolts completely. Note the condition of the slide pins and boots for reassembly or replacement.
   ℹ️If the slide pins are seized or corroded, they should be cleaned and lubricated or replaced. Do not force seized pins.

2. 2

   Support and Remove Caliper
   Carefully lift the caliper off the bracket and rotor. Do NOT disconnect the brake hose. Use a brake caliper hanger, heavy wire, or bungee cord to suspend the caliper from the suspension or chassis. Ensure there is no tension or stress on the brake hose. The caliper must be fully supported and not hanging by its hose.
   ⚠️Allowing the caliper to hang by the brake hose will damage the hose internally and can cause catastrophic brake failure.
3. 3

   Remove Brake Pads and Hardware
   Remove the inner and outer brake pads from the caliper bracket. Note the orientation and position of any anti-rattle clips, shims, or wear indicators. Remove any pad retaining clips or springs from the bracket. Keep hardware organized if reusing with new bracket.
4. 4

   Remove Caliper Bracket Bolts
   Locate the two large caliper mounting bolts that secure the caliper/bracket to the steering knuckle (front) or rear knuckle/upright (rear). Remove both mounting bolts completely, using a breaker bar if necessary. Verify the correct socket size and torque against the Brembo/Viper service specification before removal. Support the assembly as you remove the second bolt.
   ⚠These bolts are high-torque fasteners. Ensure your socket is fully seated to prevent rounding the bolt heads. If bolts are extremely tight, apply penetrating oil and allow to soak before attempting removal.

5. 5

   Remove Caliper Bracket
   Once both bolts are removed, lift the caliper bracket off the rotor and away from the mounting surface. Set the old bracket aside.
6. 6

   Clean Mounting Surfaces
   Using a wire brush and brake cleaner, thoroughly clean the mounting surface on the steering knuckle or axle housing where the bracket seats. Remove all rust, corrosion, brake dust, and old threadlocker. Clean the rotor mounting hub face if accessible. Inspect the threads in the mounting holes for damage.
   ⚠Use brake cleaner in a well-ventilated area. Avoid breathing vapors.
7. 7

   Inspect Brake Rotor
   With the bracket removed, inspect the brake rotor for excessive wear, scoring, cracking, or heat damage. Check rotor thickness with a micrometer if available and compare to manufacturer minimum thickness specification (stamped on rotor). If rotor is worn or damaged, this is the ideal time to replace it.
8. 8

   Prepare New Bracket and Bolts
   Apply medium-strength threadlocker to the threads of both caliper bracket bolts. Position the new caliper bracket over the rotor and align the mounting holes with the threaded holes in the knuckle or axle housing.
9. 9

   Install and Torque Bracket Bolts
   Thread both caliper mounting bolts into the mounting holes by hand to ensure proper thread engagement. Once both bolts are hand-tight, torque them to the manufacturer-specified value using a torque wrench (verify against the Brembo/Viper service spec). Tighten in a cross pattern to ensure even seating.
   ⚠️Improperly torqued bracket bolts can cause caliper detachment and complete brake failure. Verify your torque wrench is properly calibrated and set to the correct value.

    Install Brake Pad Hardware and Pads
    Install any anti-rattle clips, shims, or pad retaining springs onto the caliper bracket in their original positions. Apply a thin layer of silicone brake grease to the pad backing plate contact points on the bracket (where pads slide). Install the inner and outer brake pads into the bracket, ensuring they are properly seated and any wear indicators are correctly positioned (typically on inner pad, indicator should contact rotor on leading edge).
    ℹ️Do not apply grease to the friction material or rotor surface. Only lubricate metal-to-metal sliding contact points.
11. 11

    Prepare Caliper Slide Pins
    Inspect the caliper slide pins and boots. Clean the pins with brake cleaner and wipe dry. Apply a thin coat of silicone brake grease to the smooth sliding surface of each pin. Do not use petroleum-based grease. Inspect boots for tears or damage and replace if necessary.
12. 12

    Reinstall Caliper
    Remove the caliper from its support hanger or wire. If necessary, use a brake pad spreader tool to carefully and evenly compress all caliper pistons back into their bores to allow clearance for the new brake pads. Position the caliper over the rotor and pads and align the mounting bolt holes.
    ⚠When compressing the caliper piston, brake fluid will be forced back into the master cylinder reservoir. Monitor the reservoir to prevent overflow. If necessary, remove some fluid with a turkey baster before compressing pistons.
13. 13

    Install and Torque Slide Pin Bolts
    Thread both caliper slide pin bolts by hand into the caliper and bracket. Ensure the pins thread smoothly and do not cross-thread. Once hand-tight, use a torque wrench to tighten both bolts to 26 lb-ft (35 Nm).
    ⚠Over-torquing slide pin bolts can damage the pins, boots, or threads, causing caliper binding and uneven brake wear.

    Reinstall Wheel
    Position the wheel onto the hub and thread all lug nuts by hand. Lower the vehicle until the tire just contacts the ground (enough to prevent wheel rotation). Torque the lug nuts in a star pattern to the factory-specified value (approximately 100 lb-ft / 135 Nm — verify against the Viper service manual).

    Bleed Brake System and Test
    With the vehicle still raised on jack stands, pump the brake pedal slowly several times until it becomes firm. This seats the caliper pistons against the new pads. Check brake fluid level in the master cylinder reservoir and top off with DOT 4 brake fluid if needed. If any brake lines were disconnected during this procedure, the brake system must be properly bled. Lower the vehicle completely and perform a brake system function test before driving.
    ⚠️Before operating the vehicle, pump the brake pedal to verify firm pedal feel. Perform low-speed brake tests in a safe area before returning to normal driving. If the pedal feels soft, spongy, or goes to the floor, DO NOT DRIVE the vehicle. The brake system must be inspected and properly bled.

Reassembly

1. Reassembly is covered in the procedural steps above.
2. Ensure all fasteners are torqued to specification in the correct sequence.
3. If brake components were replaced on one side, consider replacing the opposite side for balanced braking performance.
4. Bedding-in new brake pads: Perform 10-15 moderate stops from 40-50 mph with 30-second cooling intervals between stops. Avoid heavy braking for the first 200 miles to allow proper pad transfer to the rotor surface.

Verification

• Verify all caliper bracket bolts are torqued to 88 lb-ft.
• Verify all caliper slide pin bolts are torqued to 26 lb-ft.
• Verify wheel lug nuts are torqued to 103 lb-ft in a star pattern.
• Pump brake pedal until firm before starting vehicle.
• Check brake fluid level in master cylinder reservoir and verify it is between MIN and MAX marks.
• With vehicle running (to enable brake assist), apply firm brake pedal pressure and verify pedal remains firm and does not slowly sink.
• Perform low-speed test stops in a safe area to verify proper brake function before returning to normal operation.
• Visually inspect for any fluid leaks around the caliper, bracket, and brake hose connections.
• After 50-100 miles, re-check wheel lug nut torque.
