Replacement of a brake caliper bracket on the 2024 Tesla Cybertruck Cyberbeast. The bracket is the heavy mount that bolts the caliper to the steering knuckle/hub assembly. Note that Cybertruck uses massive Brembo-style calipers and the brake fluid service interval (every 2 years) should be verified while the system is open.

Warnings

Tools required

Parts

• Brake caliper bracket (manufacturer-specified for Cybertruck Cyberbeast front or rear as applicable) × 1 — Refer to Tesla parts catalog by VIN
• Caliper bracket bolts (replacement recommended if TTY or if any sign of stretch) × 2 — OEM Tesla — verify reuse policy in service manual

Fluids

• DOT 3 Brake Fluid (only if brake hose is disturbed and bleeding is required) — 1 qt

Preparation

1. Park on level ground, place in P, engage parking brake.
2. Exit ALL doors with 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 Cybertruck service procedure (location and disconnect sequence differ from 12V Teslas — refer to the Cybertruck service manual).
4. DO NOT touch, cut, or pierce ANY orange cable — these are 800V 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. Loosen the wheel lug nuts slightly while the vehicle is still on the ground.
7. Place vehicle in Jack Mode via the touchscreen (if accessible before LV disconnect) so air suspension does not attempt to self-level. If LV is already disconnected, ensure the suspension is mechanically supported per Tesla procedure.
8. Lift the vehicle at Tesla-designated jacking points and support with appropriately rated jack stands. Confirm stability before going under.
9. Remove the wheel and set aside on a protected surface.
10. Take photos of the caliper, bracket, and brake hose routing before disassembly for reference.

Procedure

1. 1

   Inspect and clean work area
   Wire-brush accumulated debris from the caliper bracket bolts and surrounding knuckle area. Spray with brake cleaner. Identify the two large caliper bracket-to-knuckle bolts (these mount the bracket to the hub assembly) versus the caliper-to-bracket bolts (which hold the caliper body to the bracket).
2. 2

   Remove brake caliper from bracket
   Remove the caliper mounting bolts (caliper-to-bracket fasteners). Support the caliper with a hanger or bungee — DO NOT let it hang by the brake hose. If the caliper body must come off entirely without disturbing the hose, hang it securely from a suspension component.
   ⚠Never allow the caliper to dangle by its brake hose — internal damage to the hose can cause failure under pressure.

3. 3

   Remove brake pads and rotor (if needed for access)
   Slide the brake pads out of the bracket. Remove the rotor retaining clip (if equipped) and pull the rotor off the hub. This is required if the bracket bolts are obscured by the rotor on this assembly.
4. 4

   Remove caliper bracket from knuckle
   Using a breaker bar with the correct bit (verify drive type — these are very high-torque bolts), break loose the two caliper bracket-to-knuckle bolts. Note: these bolts were torqued to 120 Nm with threadlocker and will require significant force. Remove both bolts and lift the bracket off.
   ⚠Bracket is heavy — support it with one hand as the second bolt comes out.

5. 5

   Inspect knuckle mating surface
   Clean the bracket mounting surface on the knuckle with a wire brush and brake cleaner. Inspect for cracks, corrosion, or thread damage in the bolt holes. Chase threads if needed using the correct metric tap. Compare old and new brackets to confirm correct part.
   ℹ️If thread damage is found in the knuckle, STOP. Knuckle replacement may be required — do not install the bracket into damaged threads.
6. 6

   Install new caliper bracket
   Position the new bracket on the knuckle. Apply medium-strength blue threadlocker to the bracket bolt threads (per torque list note). Hand-thread both bolts fully before torquing to avoid cross-threading.
7. 7

   Torque caliper bracket bolts
   Torque the caliper bracket bolts to specification using a calibrated torque wrench. Verify tightening sequence with the Tesla Service Manual — alternate between bolts in stages (e.g., 50%, 80%, 100%) rather than fully torquing one then the other.
   ⚠Critical fastener. Do not use an impact gun for final torque. If a bolt feels soft or strips, STOP and replace the bolt and inspect the knuckle threads.

8. 8

   Reinstall rotor and brake pads
   Reinstall the rotor onto the hub. Verify the rotor sits flat against the hub face (no rust ridge). Slide the brake pads back into the new bracket, ensuring anti-rattle clips and shims are oriented correctly. Apply silicone brake grease to slide pin contact areas if applicable.
9. 9

   Reinstall caliper onto bracket
   Position the caliper over the pads and onto the new bracket. Install caliper mounting bolts and torque to specification. If slide pin bolts were disturbed, apply silicone brake grease to the pins and torque per spec.

10. 10

    Verify brake hose condition
    Confirm the brake hose is not twisted, kinked, or rubbing against suspension components through full steering travel (note: steer-by-wire — manual steering rotation is limited; verify per service manual). Confirm no fluid weep at the banjo fitting.
    ℹ️If the hose was disconnected during this job, replace the copper washers and bleed the system. Use DOT 3 brake fluid only.

Reassembly

1. Reinstall the wheel; hand-thread all lug nuts before applying torque.
2. Lower the vehicle until 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 low-voltage battery per Tesla procedure.
5. Allow the vehicle to wake; exit Jack Mode and let air suspension self-level.
6. With the vehicle running and in P, press the brake pedal firmly 10–15 times to seat pads against the rotor and confirm a firm pedal before driving.

Verification

• Pedal feel: brake pedal must be firm on first press — no sponginess. Spongy pedal indicates air in the system (only possible if a hydraulic line was opened).
• Visual: no brake fluid leaks at the caliper, hose, or bleeder after several firm pedal applications.
• Check for any brake-related alerts on the touchscreen — Cybertruck will report ABS/brake faults if a wheel speed sensor was disturbed.
• Low-speed test (5–10 mph in a safe area): apply brakes gently, then more firmly. Listen for grinding, scraping, or pulling. The vehicle should track straight.
• Re-torque check: after the first 50–100 miles, re-verify caliper bracket bolt torque per Tesla Service Manual recommendation for critical fasteners.
• Service interval reminder: Tesla recommends brake fluid replacement every 2 years regardless of mileage. If the fluid was disturbed or is approaching that interval, perform a full flush now.
• Lug nut re-torque: re-check wheel lug nut torque after approximately 50 miles of driving.
