Replacement of a brake caliper mounting bracket on a 2024 Model Y Long Range AWD. The bracket is the steel anchor that bolts to the knuckle/hub carrier and holds the caliper assembly; this job involves removing the wheel, caliper, and bracket without disconnecting the hydraulic line if possible.

Warnings

Tools required

Parts

• Brake caliper bracket (manufacturer-specified for Model Y, position-specific) × 1 — OEM Tesla Model Y front or rear caliper bracket — confirm corner before ordering
• Caliper bracket mounting bolts (single-use if specified by Tesla) × 2 — OEM bolts — replace if torque-to-yield or damaged
• Copper crush washers (only if banjo/hose was disconnected) × 2 — Match OEM hose fitting size

Fluids

• DOT 3 Brake Fluid (only if hydraulic line opened) — 0.5 qt

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 12V low-voltage battery (located behind/under the rear seat area on Model Y — refer to owner documentation for exact access).
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. Disable Sentry Mode and place the vehicle in Tow/Transport Mode via the touchscreen if it must be moved or rolled before lifting.
7. Loosen wheel lug nuts while the wheel is still on the ground.
8. Lift the vehicle at the manufacturer-specified jack point with a puck adapter and support on jack stands.
9. Remove the wheel and confirm which corner's bracket is being replaced (front or rear — torque differs).

Procedure

1. 1

   Inspect and document
   Photograph the caliper, bracket, hose routing, and any wear sensor or ABS wiring clipped to the bracket/knuckle area. Note pad orientation and any anti-rattle clips.
2. 2

   Relieve caliper preload
   Using a large C-clamp or piston compressor, gently push the caliper piston(s) back slightly to free the pads from the rotor. On rear calipers with integrated electric parking brake (EPB), the EPB must be put into service mode via the touchscreen (Service menu → Brakes) before retracting the piston, otherwise the EPB actuator can be damaged.
   ⚠Do not retract a rear caliper piston without first placing the EPB in service/caliper mode.
3. 3

   Remove caliper from bracket
   Remove the two caliper slide pin bolts (or guide pin bolts) securing the caliper body to the bracket. Slide the caliper off the bracket and pads. Suspend the caliper from a coil spring or control arm with wire — do not stress the brake hose.

   Caliper Slide Pin Bolts35 Nm (26 lb-ft)
4. 4

   Remove brake pads
   Remove the inner and outer pads from the bracket along with any anti-rattle/abutment clips. Inspect pads for even wear and minimum thickness; inspect the rotor surface for grooving, hot spots, or lip.
5. 5

   Remove caliper bracket from knuckle
   Remove the two large bracket-to-knuckle bolts. These are typically very tight and may have factory threadlocker — use a breaker bar with a properly seated socket. Support the bracket as the second bolt comes out.
   ⚠Bolts may be single-use per Tesla service practice — replace if any sign of stretch, galling, or damaged threads.
   Torque spec

   Bracket Bolts102 Nm (75 lb-ft)
6. 6

   Clean mating surfaces
   Wire-brush the knuckle bracket pad and the bolt threads in the knuckle. Remove old threadlocker residue. Verify no burrs or corrosion that would prevent the new bracket from seating flush.
7. 7

   Install new caliper bracket
   Position the new bracket against the knuckle. Apply medium-strength threadlocker to the bracket bolts (or use new bolts if pre-applied patch is specified). Hand-thread both bolts to avoid cross-threading, then snug.
8. 8

   Torque bracket bolts
   Torque the bracket-to-knuckle bolts to specification. Front and rear specs differ on Model Y — front uses the higher value. Verify the corner you are working on and torque accordingly. If a tightening sequence is specified by Tesla, follow it; otherwise alternate between the two bolts in 2–3 passes up to final torque.
   ⚠Verify tightening sequence with the Tesla Service Manual — front and rear bracket torques are not the same.

9. 9

   Install pads and hardware
   Install new or inspected anti-rattle clips into the new bracket. Apply a thin film of silicone brake grease to pad ear contact points (never on the friction surface). Seat the inner and outer pads in the bracket.
10. 10

    Reinstall caliper
    Inspect slide pins for smooth travel and intact boots; re-grease with silicone brake grease as needed. Slide the caliper over the pads onto the new bracket. Install the slide pin bolts and torque to specification.

11. 11

    Reattach any sensors/clips
    Re-secure ABS wheel-speed sensor harness, pad wear sensor (if equipped), and any hose retainers to their original locations on the new bracket or knuckle. Confirm no harness is contacting the rotor or suspension travel path.
12. 12

    Restore EPB and pedal
    If a rear corner was serviced, exit EPB service mode via the touchscreen so the actuator re-clamps. With ignition (vehicle awake) and brake pedal pressed several times, confirm a firm pedal before moving the vehicle.
    ⚠️Do not drive the vehicle until the brake pedal is firm and EPB has been exited from service mode.

Reassembly

1. Reinstall the wheel; hand-thread all lug nuts before applying any torque.
2. Lower the vehicle until the tire just contacts the ground, then torque lug nuts to 140 Nm (103 lb-ft) in a star pattern.
3. Fully lower the vehicle and remove jack stands.
4. Reconnect the 12V low-voltage battery and reinstall any covers/trim removed for access.
5. Wake the vehicle, clear any brake-related alerts, and confirm EPB is operational (rear job).
6. If the hydraulic hose was disconnected at any point, bleed the brake system per Tesla's sequence and top off with DOT 3 brake fluid; new copper washers required at any banjo fitting.

Verification

• With the vehicle stationary and awake, pump the brake pedal — it should be firm within 1–2 strokes with no sponginess.
• Confirm no brake, ABS, or EPB warnings on the touchscreen.
• At low speed (5–10 mph) in an empty area, perform several gentle stops to seat the pads against the rotor; listen for scraping or uneven drag.
• Recheck the wheel for free rotation when lifted (slight pad contact is normal; binding is not).
• After a short test drive, re-inspect the bracket bolts and slide pin bolts visually for any movement or fluid weeping; re-verify lug nut torque after ~50 miles.
• Note: Tesla recommends brake fluid replacement every 2 years regardless of mileage — log this service date if the system was opened or fluid was topped off.
