Replace a single front brake rotor on a 2022 Rivian EDV 500, including wheel removal, caliper bracket removal, and rotor installation.

Warnings

Tools required

Parts

• Front brake rotor × 1 — Use OEM Rivian specification
• Rotor set screw (if equipped) × 1 — Use OEM specification

Fluids

• DOT 4 Brake Fluid — 0.25 qt

Preparation

1. Ensure vehicle is powered off and in Park position
2. Chock rear wheels to prevent vehicle movement
3. Loosen front wheel lug nuts while vehicle is still on ground (do not remove)
4. Lift front of vehicle using floor jack at designated jacking point
5. Support vehicle securely on jack stands rated for vehicle weight (EDV 500 weighs approximately 6,000 lbs)
6. Remove front wheel completely and set aside
7. Inspect brake system for any signs of damage, fluid leaks, or worn components
8. Clean work area and ensure adequate lighting

Procedure

1. 1

   Inspect brake system condition
   Before beginning disassembly, thoroughly inspect the brake caliper, brake pads, brake lines, and surrounding components for damage, excessive wear, or fluid leaks. Check brake pad thickness and condition. Note any issues that may require additional repairs. Take photos if needed for reference during reassembly.
2. 2

   Remove caliper mounting bolts
   Locate the two caliper bracket mounting bolts on the rear of the caliper assembly. These are typically 18mm bolts. Use a breaker bar if necessary to break bolts loose, then remove completely with a socket wrench. Keep track of bolt location and orientation.
3. 3

   Remove caliper and bracket assembly
   Carefully lift the entire caliper and bracket assembly off the rotor. The assembly may be heavy (approximately 15-20 lbs). Do NOT disconnect the brake hose. Immediately secure the caliper assembly to the suspension or vehicle frame using wire or a bungee cord to prevent strain on the brake hose. Ensure no tension is placed on the brake line.
   ⚠️Never let caliper hang by brake hose. Support weight immediately after removal.
4. 4

   Remove rotor set screw (if equipped)
   Check if a small Phillips or hex set screw secures the rotor to the hub. If present, remove this screw. These screws are often corroded and may require penetrating oil and an impact driver. If screw strips or breaks, it can be drilled out as it only serves to hold rotor during assembly.
5. 5

   Remove old brake rotor
   Pull the brake rotor straight off the hub. If rotor is stuck due to corrosion, tap from behind with a rubber mallet, alternating positions around the rotor. Do not strike the rotor face. If severely stuck, spray penetrating oil around the hub center and wait before attempting removal again. Avoid using excessive force that could damage wheel bearings or hub.
6. 6

   Clean hub mounting surface
   Using a wire brush, thoroughly clean the wheel hub mounting surface, removing all rust, corrosion, and debris. Pay special attention to the center pilot hole and the flat mounting surface where the rotor sits. Clean surfaces ensure proper rotor seating and prevent runout issues. Wipe clean with brake cleaner and allow to dry.
7. 7

   Prepare new rotor
   Remove new rotor from packaging. New rotors are coated with a protective oil to prevent rust during storage. Clean both sides of the new rotor thoroughly with brake cleaner to remove all protective coating. Any residual oil will cause brake noise and reduced braking performance. Apply thin layer of anti-seize compound to hub center pilot area (not rotor mounting face).
8. 8

   Install new brake rotor
   Slide new brake rotor onto the wheel hub, aligning the rotor holes with the wheel studs. Ensure rotor seats completely flat against hub mounting surface with no gaps. If equipped with a rotor set screw hole, align this as well. Push firmly to ensure full seating.
9. 9

   Secure rotor with set screw
   If vehicle is equipped with a rotor set screw, install the new or cleaned original screw. Apply small amount of thread-locking compound to screw threads. Tighten securely but do not overtighten as these screws are small and easily stripped. The wheel lug nuts will ultimately secure the rotor.
10. 10

    Reinstall caliper bracket assembly
    Remove caliper assembly from its supported position. Carefully position the caliper and bracket assembly over the new rotor, aligning the bracket mounting holes with the steering knuckle mounting points. Ensure brake pads properly straddle the rotor and rotor is centered in caliper.
11. 11

    Install and torque caliper bracket bolts
    Insert both caliper bracket mounting bolts and thread by hand initially to ensure proper thread engagement. Apply thread-locking compound if specified by manufacturer. Tighten bolts in a crossing pattern. WARNING: Verified torque specifications are not available in the database. Consult official Rivian service manual for proper torque values. Typical values for similar vehicles range from 120-150 ft-lbs, but you MUST verify for this specific vehicle before final tightening.
    ⚠️Incorrect caliper bracket torque can cause caliper detachment and complete brake failure. Verify exact torque specification from Rivian service documentation before tightening.
12. 12

    Verify caliper and rotor operation
    Before installing wheel, visually verify rotor spins freely without rubbing on caliper or pads. Check that brake pads are properly seated against the rotor. Gently spin rotor by hand to confirm smooth rotation with only slight drag from pads. Inspect all brake lines and connections for any damage that may have occurred during service.
13. 13

    Reinstall wheel
    Mount wheel onto hub, ensuring it sits flush against rotor. Install all lug nuts by hand first, threading them completely. Tighten lug nuts in a star pattern to initial snugness (do not fully torque yet while vehicle is on jack stands). Lower vehicle to ground before final torque.

Reassembly

1. Once vehicle is lowered to ground and weight is on wheels, torque wheel lug nuts to manufacturer specification (typically 140-150 ft-lbs for Rivian, but verify in owner's manual) using a star pattern
2. Pump brake pedal several times until pedal feels firm and reaches normal height before attempting to drive
3. Check brake fluid level in master cylinder reservoir and top off with DOT 4 brake fluid if necessary
4. Test brakes at low speed in a safe area before returning to normal driving
5. Dispose of old rotor according to local recycling regulations

Verification

• Pump brake pedal 10-15 times with vehicle running (ready mode). Pedal should become firm and maintain consistent height
• Check for any brake fluid leaks around caliper and brake lines
• Verify wheel lug nuts are torqued to specification using torque wrench
• Perform low-speed brake test (5-10 mph) in safe area to confirm braking function before road use
• Listen for any unusual noises during initial brake applications (light squeaking is normal for first few stops with new rotors)
• Drive cautiously for first 50-100 miles to allow proper bedding-in of new rotor with brake pads
• Verify no brake warning lights appear on instrument cluster
• After 50-100 miles, re-check wheel lug nut torque and brake fluid level
