Brake Rotors - Rear Pair

Replace both rear brake rotors on a 2024 Tesla Cybertruck Dual Motor. The Cybertruck uses large rear rotors with an integrated electric parking brake (EPB) caliper that must be retracted via service mode before disassembly.

Warnings

Tools required

Parts

• Rear brake rotor (Cybertruck-specific) × 2 — Manufacturer-specified rear rotor for 2024 Cybertruck Dual Motor
• Rotor retaining set screw (if damaged on removal) × 2 — OEM specification

Preparation

1. Park on level ground, place in P, engage parking brake (you will release it via service mode shortly).
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's documented procedure for Cybertruck (location and procedure differ from 12V Teslas — refer to the Service Manual).
4. DO NOT touch, cut, or pierce ANY orange cable — these are high-voltage 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. Before disconnecting LV power: on the touchscreen, enter Service Mode and place the rear electric parking brake into Service/Transport mode to retract the EPB pistons. Also enable Jack Mode to disable air suspension self-leveling.
7. Loosen rear wheel lug nuts while the vehicle is still on the ground.
8. Lift the rear of the vehicle at the OEM-specified jack points and support on rated jack stands. Remove both rear wheels.
9. Inspect rotors, pads, caliper, dust shield, and wheel speed sensor wiring before disassembly; note any damage.

Procedure

1. 1

   Confirm EPB is in service mode
   Verify the rear parking brake actuators are fully retracted (service/transport mode) before attempting to push the caliper pistons back. Attempting to compress an active EPB piston mechanically can destroy the actuator gearbox.
   ⚠Do not wind back the rear caliper pistons with a manual tool unless the EPB has been retracted via the touchscreen first.
2. 2

   Remove caliper slide/guide pin bolts
   At the rear caliper, remove the two caliper slide pin bolts holding the caliper body to the bracket. Slide the caliper off the bracket and pads. Support the caliper with a hanger — DO NOT let it dangle from the EPB wiring or flexible brake hose.
   ⚠Do not disconnect the EPB electrical connector unless absolutely necessary; if you must, ensure the 48V LV battery is disconnected first.

3. 3

   Remove brake pads
   Slide the outer and inner brake pads out of the caliper bracket. Inspect anti-rattle clips and retain them if reusing. Inspect pads for wear and uneven friction patterns — replace if at or below the manufacturer-specified minimum thickness.
4. 4

   Remove caliper mounting bracket
   Remove the two large bolts securing the caliper bracket to the rear knuckle. These are typically high-torque fasteners and may have factory threadlocker — use a breaker bar.

   Bracket Bolts102 Nm (75 lb-ft)
5. 5

   Remove rotor set screw
   Remove the small Torx/hex retaining screw securing the rotor to the hub face. These corrode easily — apply penetrating oil and use a properly sized bit to avoid stripping. Replace the screw if damaged.
   Torque spec

   Rotor Set Screws7 Nm (5 lb-ft)
6. 6

   Remove the rotor
   Pull the rotor straight off the hub. If seized, thread bolts into the rotor's threaded jacking holes (if equipped) and tighten evenly to break it free, OR use a dead-blow mallet on the rotor hat — never strike the hub or wheel speed sensor area.
   ℹ️Do not pry between the hub face and rotor with a steel tool — you can damage the hub or the WSS tone ring.
7. 7

   Clean the hub face
   Wire-brush the hub face to remove all corrosion and debris. The new rotor must seat flat against bare, clean metal — any corrosion buildup will cause lateral runout and brake judder. Optionally apply a very thin film of anti-seize to the hub center bore (NOT the friction surface or studs).
8. 8

   Install new rotor
   Wipe the new rotor's friction surfaces clean with brake parts cleaner to remove shipping oil. Install the rotor onto the hub and secure with the set screw.

9. 9

   Reinstall caliper bracket
   Apply medium-strength threadlocker to the caliper bracket bolt threads (unless they are pre-coated single-use bolts — replace if so). Torque to spec.

10. 10

    Reinstall pads and caliper
    Install brake pads (new pads recommended any time rotors are replaced) with anti-rattle hardware. Apply silicone brake grease to the slide pins, slide caliper over the pads, and torque the slide pin bolts.

    Repeat on opposite rear wheel
    Repeat steps 1–10 on the other rear corner.
12. 12

    Reinstall wheels
    Mount each rear wheel and torque the lug nuts in a star pattern in two passes (half torque, then full torque).

    Wheel Lug Nuts140 Nm (103 lb-ft)

Reassembly

1. Lower the vehicle to the ground.
2. Reconnect the 48V low-voltage battery per Tesla's Cybertruck-specific procedure.
3. Re-enter the vehicle, wake the system, and exit Service Mode / Jack Mode via the touchscreen.
4. Take the EPB out of service mode so the actuators re-engage. Cycle the parking brake on/off several times via the touchscreen and confirm no fault messages.
5. With the vehicle still stationary and in P, press the brake pedal firmly several times until it feels firm — this seats the pads against the new rotors. Do NOT drive until pedal is firm.
6. Inspect for any brake fluid leaks at the caliper (none should be present since the hydraulic system was not opened).

Verification

• Check the touchscreen for any ABS, EPB, or brake-related alerts — there should be none.
• At low speed in an empty area, perform several gentle stops to bed in the new pads/rotors per the pad manufacturer's bedding procedure. Listen for any scraping, grinding, or pulsation.
• After bedding, inspect both rear rotors for even pad transfer (uniform gray friction band across the full swept area).
• Confirm the parking brake holds the vehicle on a moderate incline.
• Re-torque the wheel lug nuts after approximately 50–100 miles of driving in a star pattern.
• Service reminder: Tesla recommends brake fluid replacement every 2 years regardless of mileage — note the date and consider scheduling if it is due.
