This procedure covers the removal and replacement of the brake caliper bracket on a 2024 Rivian EDV 500, including removal of the caliper and brake pads to access the bracket mounting bolts.

Warnings

Tools required

Parts

• Brake caliper bracket × 1 — Use OEM specification
• Brake caliper bracket bolts × 2 — Use OEM specification
• Brake pads (if worn or contaminated) × 1 — Use OEM specification

Fluids

• DOT 4 Brake Fluid — 0.25 qt

Preparation

1. Park vehicle on a flat, level surface and place transmission in Park
2. Apply parking brake firmly (note: you will release this if working on rear brakes)
3. Place wheel chocks behind wheels that will remain on the ground
4. Power down the vehicle completely and remove key fob from vehicle vicinity
5. Loosen wheel lug nuts while vehicle is still on the ground (do not remove)
6. Lift vehicle using floor jack at designated lift points per owner's manual
7. Secure vehicle on jack stands at proper support points
8. Remove wheel and tire assembly completely
9. If working on rear brakes, release parking brake at this point
10. Inspect brake components for unusual wear, damage, or fluid leaks before proceeding

Procedure

1. 1

   Prepare brake caliper for removal
   Before removing any bolts, use a brake pad spreader or C-clamp to gently push the caliper piston back into its bore. This relieves pressure on the caliper and makes removal easier. Place a rag over the spreader to protect the caliper and pad surfaces. Check the brake fluid reservoir and remove some fluid if necessary to prevent overflow.
2. 2

   Remove brake caliper mounting bolts
   Locate the two caliper slide pin bolts or mounting bolts that secure the caliper to the bracket. These are typically on the back side of the caliper assembly. Use the appropriate socket to remove both bolts completely. Note the location and orientation of any washers or hardware.
3. 3

   Remove and support brake caliper
   Carefully lift the brake caliper off the bracket and rotor. Do NOT disconnect the brake hose. Immediately support the caliper using a brake caliper hanger hooked to the suspension or tie it securely with wire to prevent any tension on the brake hose. Ensure the caliper is stable and the hose has no kinks or stress points.
   ⚠️Allowing the caliper to hang by the brake hose can cause internal hose damage leading to brake failure.
4. 4

   Remove brake pads and hardware
   Remove the brake pads from the caliper bracket. Note their orientation and the location of any anti-rattle clips, shims, or springs. Take photos if helpful for reassembly. Remove all pad hardware from the bracket as it will interfere with bracket removal.
5. 5

   Locate caliper bracket mounting bolts
   Identify the caliper bracket mounting bolts. These are typically two large bolts that attach the bracket directly to the steering knuckle or axle housing. They are usually located behind where the caliper was mounted and are significantly larger than the caliper mounting bolts. Clean the area around the bolt heads.
6. 6

   Remove caliper bracket mounting bolts
   Using a breaker bar and appropriate socket, remove both caliper bracket mounting bolts. These bolts are torqued to high specification and may require significant force to break loose. Apply force steadily and ensure the socket is fully seated to avoid rounding the bolt heads. Remove both bolts completely.
   ⚠These bolts are very tight. Ensure your tools are properly positioned and the vehicle is stable before applying force.
7. 7

   Remove caliper bracket
   Once both mounting bolts are removed, lift the caliper bracket away from the rotor and knuckle. The bracket may be snug; wiggle gently if needed. Inspect the mounting surface on the knuckle for corrosion, damage, or debris.
8. 8

   Clean mounting surfaces
   Use a wire brush to thoroughly clean the caliper bracket mounting surface on the knuckle and the bolt holes. Remove all rust, corrosion, and debris. Clean the mounting surfaces on the new or reinstalled bracket as well. Spray with brake cleaner and wipe dry. Inspect threads in the knuckle bolt holes for damage.
9. 9

   Install new or serviced caliper bracket
   Position the caliper bracket onto the knuckle, aligning the bolt holes. If installing new bracket bolts, apply medium-strength thread locker to the threads per manufacturer recommendation. Start both bracket mounting bolts by hand to ensure proper thread engagement before tightening.
   ⚠️CRITICAL: Without manufacturer torque specifications, you cannot safely complete this installation. You MUST obtain official Rivian torque values for these bolts. Improper torque can cause bracket failure and complete loss of braking ability.
10. 10

    Torque caliper bracket bolts
    Using a calibrated torque wrench, tighten the caliper bracket mounting bolts to the manufacturer's specified torque value in a cross-pattern (alternating between bolts). Since torque specifications are not available in this database, you must obtain them from Rivian service documentation before proceeding. Do not guess or estimate these critical fastener torques.
    ⚠️Do not proceed without verified manufacturer torque specifications. Contact a Rivian dealer or service center for official specifications.
11. 11

    Reinstall brake pad hardware and pads
    Install all anti-rattle clips, shims, and springs onto the caliper bracket in their original positions. Install brake pads into the bracket, ensuring they are properly seated and oriented correctly (wear indicators should be positioned per service manual). Verify pads move freely in the bracket.
12. 12

    Reinstall brake caliper
    Remove the caliper from its support hanger or wire. Position the caliper over the brake pads and bracket, aligning the caliper mounting bolt holes. Ensure the brake hose is not twisted. Install the caliper mounting bolts and tighten to manufacturer specification using a torque wrench. Again, you must obtain these torque values from official Rivian documentation.
13. 13

    Check brake system
    Before installing the wheel, visually inspect the entire brake assembly. Verify all bolts are installed and properly torqued, the caliper moves freely on its pins if applicable, pads are properly seated, and there are no loose components. Spin the rotor by hand to ensure it rotates freely without binding.

Reassembly

1. Reinstall wheel and tire assembly, starting all lug nuts by hand
2. Lower vehicle partially so tire contacts ground but vehicle weight is still on jack stands
3. Torque wheel lug nuts to manufacturer specification in a star pattern
4. Completely lower vehicle and remove jack stands
5. Before moving vehicle, pump brake pedal repeatedly until it becomes firm and reaches normal height
6. Check brake fluid level in reservoir and top off with DOT 4 brake fluid if needed
7. Start vehicle and verify brake warning lights are not illuminated

Verification

• With vehicle stationary, apply brake pedal firmly multiple times. Pedal should be firm and not sink to the floor
• Check for any brake fluid leaks around the caliper, bracket, and brake hose connections
• Perform a low-speed test drive in a safe area, testing brakes at increasing speeds
• Verify no unusual noises, vibrations, or pulling to one side during braking
• Confirm brake pedal feel is normal and stopping power is consistent
• After test drive, recheck all bolts are tight and inspect for any fluid leaks
• If any abnormalities are detected, do not drive the vehicle and seek professional service immediately
• Perform additional brake bedding procedure if new pads were installed per manufacturer recommendations
