Brake Rotors - Front Pair

Replace both front brake rotors on a 2024 Tesla Cybertruck Cyberbeast. The Cybertruck uses large-diameter front rotors with fixed/floating calipers on a 48V architecture vehicle — standard brake hydraulics are unaffected by the 48V system, but service procedures still require LV battery disconnection.

Warnings

Tools required

Parts

• Front brake rotors (Cybertruck-specific, OEM or OE-equivalent) × 2 — Tesla Cybertruck front rotor — verify exact size/offset against VIN
• Rotor retaining set screws (if reusing not advised) × 2 — OEM-spec set screw

Preparation

1. Park on level ground, place in P, engage parking brake.
2. Exit ALL doors with the key fob away from the vehicle. Wait at least 2 minutes for HV systems to fully de-energize, even on this non-HV job.
3. Disconnect the low-voltage battery. NOTE: Cybertruck uses a 48V LV architecture (not 12V) — locate the LV battery per the Cybertruck Owner's Manual and follow the manufacturer-specified disconnect procedure.
4. DO NOT touch, cut, or pierce ANY orange cable — these are high-voltage (800V on Cybertruck) and lethal.
5. If at any point you encounter an orange cable, an HV component, or are unsure if a system is de-energized: STOP and consult a Tesla-certified technician.
6. Place the vehicle in Transport / Jack Mode via the touchscreen to disable air suspension self-leveling before lifting. Confirm suspension does not attempt to adjust.
7. Loosen front lug nuts while the wheels are still on the ground.
8. Lift the front of the vehicle at the manufacturer-specified jack points using rated equipment, and support on jack stands. Never work under a vehicle supported only by a jack.

Procedure

1. 1

   Remove front wheels
   Fully remove the front lug nuts and pull both front wheels off. Set wheels face-down on a clean surface to protect finish. Inspect lug studs and hub face for damage or corrosion.
2. 2

   Inspect brake assembly before disassembly
   Photograph the caliper, bracket, and brake line routing. Note pad wear, caliper piston condition, and any signs of fluid leakage. This documentation makes reassembly faster and helps catch missing hardware.
3. 3

   Remove caliper from caliper bracket
   Depending on caliper design, either remove the two caliper slide pin bolts (floating caliper) or the two caliper-to-bracket bolts (fixed caliper). Support the caliper with a hanger or bungee — never let it hang by the flexible brake line. Do not disconnect the brake line; it is not necessary for rotor replacement.
   ⚠Hanging the caliper by the brake hose can damage the hose internally and cause failure later.

4. 4

   Remove caliper bracket
   Remove the two front caliper bracket bolts securing the bracket to the steering knuckle. These are high-torque fasteners and may require a breaker bar. Set the bracket aside on a clean surface.

5. 5

   Remove rotor set screw and rotor
   Remove the small set screw retaining the rotor to the hub. If seized, use an impact driver with a properly sized bit to avoid stripping. Pull the rotor straight off the hub. If it is stuck due to corrosion, apply penetrant at the hub-rotor interface and tap the rotor face evenly with a soft mallet — never strike the hub or wheel speed sensor.
   ⚠Do not strike the wheel speed sensor or the steer-by-wire actuator components while freeing a stuck rotor.

6. 6

   Clean hub mating surface
   Wire-brush the hub face to remove all corrosion and debris. The new rotor must seat flat against the hub or runout/vibration will result. A very thin film of anti-seize on the hub center (not on the friction surface) helps prevent future seizure. Wipe the new rotor's friction surfaces with brake cleaner to remove shipping oil.
   ⚠Keep all lubricants off the rotor friction surfaces and pad faces.
7. 7

   Install new rotor
   Slide the new rotor onto the hub, aligning the set screw hole. Install and tighten the rotor set screw to specification. The set screw is for retention during assembly only — wheel lug clamp force holds the rotor in service.

   Reinstall caliper bracket
   Position the caliper bracket onto the knuckle. Apply medium-strength threadlocker to the caliper bracket bolt threads. Install bolts and torque to specification. Verify the bracket is fully seated and bolts pull down evenly.

   Inspect pads and reinstall caliper
   Inspect brake pads for even wear and remaining material. If pads are worn or contaminated, replace as a pair. Clean and lubricate caliper slide pins with silicone brake grease. Reinstall the caliper over the rotor and torque the slide pin bolts (or caliper bolts, depending on design) to specification.

    Repeat on opposite front side
    Repeat steps 1 through 9 on the other front wheel. Always service rotors as a pair to maintain even braking performance.

Reassembly

1. Reinstall front wheels and hand-thread all lug nuts before lowering.
2. Lower the vehicle until the tires just touch the ground, then torque lug nuts in a star pattern to specification.
3. Fully lower the vehicle and remove jack stands.
4. Reconnect the 48V LV battery following the manufacturer-specified procedure.
5. Close all doors and allow the vehicle to wake. Exit Jack Mode if it remains active and allow the air suspension to re-level.
6. With the vehicle in Park and brake firmly held, pump the brake pedal several times until firm to seat the pads against the new rotors before driving.

Verification

• Confirm a firm brake pedal before moving the vehicle. A spongy pedal means pads are not yet seated or air has entered the system.
• Check the touchscreen for any ABS, traction control, or brake-related alerts. Cybertruck integrates brake monitoring with the steer-by-wire and stability control systems — any alert must be resolved before road use.
• Perform a low-speed brake test in a safe area: apply brakes from 5–10 mph multiple times to confirm even, straight stopping with no pulling, grinding, or pulsation.
• Bed in the new rotors per the rotor manufacturer's procedure (typically a series of moderate stops from 35–40 mph followed by a cool-down). Avoid hard stops and parking with hot brakes for the first ~200 miles.
• Re-torque lug nuts to specification after approximately 50–100 miles of driving.
• Reminder: Tesla recommends brake fluid replacement every 2 years. If this interval is approaching, schedule that service — opening the bleeders during rotor service is not required, but the bleeder torque spec is provided in case fluid service is performed at the same time.
• Torque the bleeder screw to specification only if it was opened during this service.
