Replacement of a brake caliper bracket on a 2024 Cybertruck Dual Motor AWD. The bracket holds the caliper to the knuckle/hub assembly and must be torqued to spec with thread locker; brake hydraulics are not opened on this job unless the caliper is fully removed from its hose.

Warnings

Tools required

Parts

• Caliper bracket (manufacturer-specified for Cybertruck Dual Motor, correct corner) × 1 — OEM Tesla Cybertruck caliper bracket — verify against VIN
• Caliper bracket-to-knuckle bolts (replace if single-use TTY — verify with service manual) × 2 — OEM-spec bolts, threadlocker pre-applied or apply medium-strength threadlocker
• Medium-strength threadlocker × 1 — Loctite 243 or equivalent
• Silicone brake grease (for slide pins if disturbed) × 1 — Silicone-based caliper grease
• Copper crush washers (only if banjo bolt is disturbed) × 2 — OEM-spec copper washers for brake hose banjo

Fluids

• DOT 3 Brake Fluid (only if hydraulic circuit is opened) — 1 qt

Preparation

1. Park on level ground, place in P, and engage the 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 — connectors and disconnect procedure differ from 12V Teslas. Follow the manufacturer-specified LV disconnect procedure for this vehicle.
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. Place the vehicle in Jack Mode via the touchscreen (Controls → Service → Jack Mode) to disable air suspension self-leveling.
7. Loosen wheel lug nuts while the wheel is still on the ground.
8. Lift the vehicle at the manufacturer-specified jack point using a Tesla-approved puck and support on rated jack stands.
9. Remove the wheel and set aside on a protected surface (avoid contact with stainless body).

Procedure

1. 1

   Inspect and document
   Photograph the caliper, bracket, hose routing, and fastener positions before disassembly. Note pad wear, rotor condition, and any signs of fluid leakage. Confirm correct replacement bracket matches the corner being serviced.
2. 2

   Relieve caliper piston pressure (if reusing pads)
   If pads will be reused, gently retract the caliper piston slightly using a C-clamp or piston tool against an old pad. This eases caliper removal and reseating. Do not force fluid back through ABS modulator with bleeder closed if system contamination is suspected.
3. 3

   Remove caliper from bracket
   Remove the caliper slide pin / guide bolts to separate the caliper body from the bracket. Support the caliper with a hanger or bungee — DO NOT allow it to hang by the brake hose. Leave the brake hose connected if possible to avoid opening the hydraulic system.
   ⚠Hose damage from hanging the caliper will require hose replacement and a full system bleed.

4. 4

   Remove brake pads and rotor (as needed for access)
   Slide the brake pads out of the bracket. Remove the rotor retaining clip/screw if present, then pull the rotor off the hub to gain clear access to the bracket bolts. Inspect the hub face for corrosion.
5. 5

   Remove caliper bracket from knuckle
   Using a breaker bar, loosen and remove the two caliper bracket-to-knuckle bolts. These are torqued high and may have factory threadlocker — expect significant breakaway force. Support the bracket as the second bolt comes out.
   ⚠If TTY (torque-to-yield) bolts are specified by Tesla, replace them rather than reuse. Verify with the Tesla Service Manual for this VIN.

6. 6

   Clean knuckle mating surface
   Wire-brush the bracket mounting bosses on the knuckle. Remove old threadlocker residue from threads with a thread chaser if available (do not cut new threads with a tap unless the manufacturer specifies). Wipe clean with brake cleaner.
7. 7

   Install new caliper bracket
   Position the new bracket against the knuckle. Apply medium-strength threadlocker to the bracket bolts (unless pre-applied patch is present). Hand-thread both bolts fully before torquing to avoid cross-threading.
8. 8

   Torque caliper bracket bolts
   Torque the caliper bracket-to-knuckle bolts to the verified front spec. Tighten in the sequence specified by the Tesla Service Manual — verify sequence with manual before final torque.
   ⚠Tightening sequence on multi-bolt brackets is critical to prevent distortion. Verify sequence with the service manual.

   Reinstall rotor and brake pads
   Reinstall the rotor and any retaining clip. Seat the brake pads into the bracket abutments with anti-rattle clips/shims in their original positions.

    Reinstall caliper
    Inspect slide pin boots for damage; replace if torn. Apply silicone brake grease to the slide pins per manufacturer guidance. Reinstall the caliper over the pads onto the bracket and torque the slide pin bolts to spec.

    Reinstall wheel
    Mount the wheel onto the hub. Hand-start all lug nuts. Snug in a star pattern, then lower the vehicle until tires contact the ground but weight is still partially supported, and final-torque in a star pattern to spec.

Reassembly

1. Lower the vehicle fully and remove jack stands.
2. Reconnect the low-voltage battery per the manufacturer-specified procedure for the 48V system.
3. Exit Jack Mode via the touchscreen and allow the air suspension to re-level.
4. With the vehicle running and in P, depress the brake pedal firmly several times to seat the pads against the rotor and restore pedal feel before driving.
5. Verify brake fluid level at the reservoir; top off with DOT 3 only if needed.
6. If the hydraulic system was opened at any point, perform a full brake bleed in the manufacturer-specified sequence.

Verification

• Confirm a firm, high brake pedal before moving the vehicle. A soft pedal indicates air in the system or improper caliper seating — do not drive.
• Inspect for any brake fluid weeping at the banjo fitting or bleeder if either was disturbed.
• Perform low-speed brake tests in a safe area: light, then progressively firmer applications, checking for pull, noise, or vibration.
• After a short test drive, re-check lug nut torque and inspect the bracket area for any movement, leaks, or unusual heat.
• Clear any stored brake/ABS fault codes via the Tesla touchscreen service menus and confirm no warning messages remain.
• Reminder: Tesla recommends brake fluid replacement every 2 years regardless of mileage — log this service date if fluid was changed.
