Brake Rotor - Rear Single

Replace a single rear brake rotor on a 2024 Tesla Cybertruck Cyberbeast. The Cybertruck uses a 48V low-voltage architecture and steer-by-wire, but rear brake rotor service itself is mechanically conventional with oversized hardware due to the truck's ~6,800 lb curb weight.

Warnings

Tools required

Parts

• Rear brake rotor (Cybertruck rear-specific) × 1 — Tesla OEM rear rotor for Cybertruck Cyberbeast — verify by VIN
• Rotor set screw (if damaged on removal) × 1 — OEM specification

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 48V low-voltage battery per Tesla service procedure (Cybertruck uses a 48V LV architecture — NOT 12V). Confirm location and disconnect sequence in the Tesla Service Manual for this VIN.
4. DO NOT touch, cut, or pierce ANY orange cable — these are 800V and lethal.
5. If 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. On the touchscreen, enable Jack Mode (Service > Jack Mode) to disable air suspension self-leveling before lifting.
7. Chock the front wheels. Steer-by-wire means the front wheels will not be held by a steering lock once LV power is removed.
8. Loosen the rear wheel lug nuts slightly while the vehicle is on the ground.
9. Lift the rear of the vehicle at the manufacturer-specified lift points and support on jack stands rated for the Cybertruck's weight.
10. Remove the rear wheel.

Procedure

1. 1

   Inspect and document
   Photograph the caliper, bracket, and rotor orientation. Note any directional markings on the rotor vanes if present. Inspect the caliper, slide pins, pads, and dust boots for damage; if pads or hardware need replacement, plan accordingly before reassembly.
2. 2

   Retract the parking brake (if electronic)
   The Cybertruck rear caliper integrates an electronic parking brake actuator. Before disassembly, place the EPB into Service/Transport Mode using the touchscreen service menu so the actuator retracts and will not attempt to clamp during work. If you cannot confirm the EPB is in service mode, STOP and refer to the Tesla Service Manual — forcing the actuator can destroy it.
   ⚠Do not manually wind back an EPB-equipped rear caliper piston without first commanding service mode. Doing so can damage the actuator gear train.
3. 3

   Disconnect the EPB connector (if required for caliper removal)
   If the caliper must be moved far enough to require disconnecting the parking brake motor harness, release the connector lock and unplug it. Support the harness so it is not strained.
4. 4

   Remove caliper from bracket
   Remove the two caliper slide/guide bolts securing the caliper body to the bracket. Slide the caliper off the rotor and suspend it from the suspension with a caliper hanger — do NOT let it hang by the brake hose.
   ⚠Never let the caliper hang by the flexible brake line — internal damage can cause failure under braking.

   Remove caliper bracket
   Remove the two caliper bracket bolts securing the bracket to the rear knuckle. Lift the bracket clear of the rotor.

6. 6

   Remove rotor set screw and rotor
   Remove the rotor retaining set screw(s). If corrosion is present, a few light taps with a brass or dead-blow hammer on the rotor hat (not on the stainless exoskeleton or wheel studs) will free it. If the rotor will not release, apply penetrating oil at the hub-rotor interface and use a manufacturer-specified rotor removal screw in the threaded jacking hole if equipped.
   ⚠Do not strike the wheel studs or use heat near wheel speed sensor wiring or the EPB harness.

   Clean the hub mating face
   Wire-brush the hub face to bare, smooth metal. Any rust or debris will cause rotor runout and brake pulsation. Wipe with brake cleaner. Optionally apply a very thin film of anti-seize to the hub center pilot only — keep it off the friction surface and lug threads.
8. 8

   Install the new rotor
   Wipe both friction surfaces of the new rotor with brake cleaner to remove the shipping preservative. Install onto the hub aligning the set-screw hole. Install and torque the rotor set screw.
   ℹ️Failure to remove the shipping oil from the rotor will severely contaminate new pads and impair braking.

   Reinstall caliper bracket
   Position the bracket on the knuckle and install both bracket bolts. Torque to specification. If the bolts are single-use or threadlocked from the factory, replace per Tesla Service Manual guidance.

    Inspect pads and slide pins, then reinstall caliper
    Inspect brake pad thickness and slide pin movement. If slide pins were removed, clean and reapply silicone brake grease before reinstalling. If pads will be reused, mark orientation. If a new rotor is paired with worn pads, strongly consider replacing pads. Reinstall caliper over the rotor and torque the caliper bolts.

    Reconnect EPB harness
    Reconnect the parking brake actuator connector if it was disconnected. Verify the connector is fully latched and the harness is routed in its original clips, away from the rotor and suspension travel.

Reassembly

1. Reinstall the rear wheel. Hand-thread all lug nuts before applying torque.
2. Lower the vehicle until the tire just contacts the ground, then torque the lug nuts in a star pattern to specification (Wheel Lug Nuts).
3. Fully lower the vehicle and remove jack stands.
4. Reconnect the 48V low-voltage battery per Tesla service procedure.
5. Exit Jack Mode and exit EPB Service Mode via the touchscreen. Allow the air suspension to re-level.
6. With the brake pedal depressed firmly several times, confirm a high, firm pedal before moving the vehicle. The pedal MUST be solid before driving — the caliper piston needs to take up clearance after being disturbed.
7. Cycle the parking brake on/off several times via the screen/stalk to confirm EPB actuator function and no fault messages.

Verification

• Confirm no ABS, EPB, or brake warning messages on the touchscreen after a full power cycle.
• Perform a low-speed (5-10 mph) brake test in a safe area to confirm pedal feel and that the vehicle does not pull.
• Bed in the new rotor following the rotor manufacturer's procedure (typically a series of moderate stops from ~35 mph) — the regen-heavy Cybertruck otherwise rarely uses the friction brakes, which can lead to uneven pad transfer.
• After a short test drive, re-check lug nut torque (Wheel Lug Nuts) and inspect for any fluid leakage at the caliper.
• Visually confirm even pad contact pattern on the new rotor after the test drive.
• Service reminder: Tesla recommends brake fluid replacement every 2 years regardless of mileage. If the fluid has not been serviced within that interval, schedule a full brake fluid flush with DOT 3 fluid.
