Complete brake fluid bleed at all four corners on a 2024 Model Y Long Range AWD. Tesla recommends brake fluid replacement every 2 years regardless of mileage; this procedure refreshes fluid and removes air from the hydraulic system.

Warnings

Tools required

Parts

• Bleeder screw dust caps (replace if cracked/missing) × 4 — OEM or equivalent

Fluids

• DOT 3 Brake Fluid (sealed, fresh container) — 1 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. On the 2024 Model Y, the 12V (lithium-ion) battery is accessed under the front trunk/frunk area — follow Tesla's documented disconnect sequence.
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 Transport / Service Mode if you intend to keep the 12V connected for ABS module operation — otherwise plan to bleed manually with 12V disconnected.
7. Loosen (do not remove) all four wheel lug nuts while tires are on the ground.
8. Lift the vehicle at the four manufacturer-designated lift points using approved pucks. Support on jack stands rated for EV curb weight.
9. Remove all four wheels.
10. Inspect brake fluid reservoir level and condition. If fluid is dark/brown, plan a full flush rather than a top-up bleed.
11. Using a clean suction tool, evacuate old fluid from the reservoir down to the MIN line. Refill with fresh DOT 3 to MAX. Do NOT let the reservoir run dry during bleeding — this introduces air into the master cylinder/HCU.

Procedure

1. 1

   Identify bleed sequence
   Use the bleed sequence specified in the Tesla Service Manual for the 2024 Model Y. The conventional 'farthest-from-master-first' rule does not always apply to Tesla's hydraulic layout. Verify the correct order before starting — incorrect sequence can leave air trapped in the HCU.
   ⚠Verify bleed sequence with the official service manual — do not assume.
2. 2

   Locate first caliper bleeder screw
   At the first wheel in the bleed sequence, locate the bleeder screw on the back of the caliper. Remove the dust cap and clean the bleeder fitting with brake cleaner to prevent debris from entering the system.
3. 3

   Attach bleeder hose and catch bottle
   Fit a clear hose snugly over the bleeder screw and route it into a catch bottle containing a small amount of fresh brake fluid (so the hose end is submerged — prevents air from being drawn back in).
4. 4

   Bleed first caliper
   Using either a pressure bleeder at the reservoir, a vacuum bleeder at the caliper, or a two-person pedal-pump method, flush fluid through the caliper until the discharged fluid runs clear and bubble-free. For two-person method: assistant slowly depresses pedal, you open bleeder ~1/4 turn, fluid flows, you close bleeder BEFORE assistant releases pedal. Repeat. Check reservoir level every 4-5 strokes and top up — never let it drop below MIN.
   ⚠If reservoir runs dry, air enters the master cylinder/HCU and a full system bleed (likely requiring Tesla service software) becomes necessary.
5. 5

   Close bleeder and torque
   Close the bleeder screw. Torque to specification — do not overtighten, as bleeder screws are easily snapped off in the caliper.

6. 6

   Reinstall dust cap
   Wipe the bleeder area clean and reinstall the dust cap to keep dirt and moisture out.
7. 7

   Repeat at second wheel in sequence
   Move to the second caliper per the manufacturer-specified sequence and repeat steps 2-6. Continuously monitor reservoir level.

8. 8

   Repeat at third wheel in sequence
   Move to the third caliper per the manufacturer-specified sequence and repeat steps 2-6. Top up reservoir as needed.
   Torque spec

   Bleeder Screw10 Nm (7 lb-ft)
9. 9

   Repeat at fourth wheel in sequence
   Move to the final caliper per the manufacturer-specified sequence and repeat steps 2-6. Confirm clean, bubble-free fluid is exiting.

    Final reservoir level check
    With all bleeders closed, set the brake fluid reservoir to the MAX line with fresh DOT 3 fluid. Wipe down the reservoir cap area and reinstall the cap securely.

Reassembly

1. Inspect each caliper for any fluid weeping at the bleeder or banjo/line fittings.
2. Reinstall all four wheels. Hand-thread lug nuts to prevent cross-threading on the aluminum hubs.
3. Snug lugs in a star pattern, then lower the vehicle to the ground.
4. Final-torque the wheel lug nuts in a star pattern to the verified specification.
5. Reconnect the 12V low-voltage battery.
6. Allow the vehicle to fully wake and complete its self-checks before driving.

Verification

• With the vehicle awake and 12V reconnected, press the brake pedal multiple times. Pedal should be firm and high — not soft or sinking.
• Check the dash for any ABS, traction control, or brake system warning indicators. Any new warning may indicate air in the HCU requiring a Tesla Toolbox-assisted bleed.
• Inspect each caliper bleeder and brake line fitting for leaks after pedal pressurization.
• Test drive at low speed in a safe area: confirm straight, even braking with no pull. Test ABS engagement on a low-traction surface if possible — the system should cycle normally.
• Verify regenerative braking still functions normally (check energy graph during deceleration).
• Log the service date — Tesla's recommended brake fluid interval is every 2 years regardless of mileage. Set a reminder for the next service.
• Recheck reservoir level after the test drive and top up to MAX if needed.
