Tesla Brake Hose Replacement Easy DIY Guide
Have you found a brake fluid leak on your Tesla? The issue could be a leaking or faulty brake hose. This DIY guide walks you through replacing the brake hose with easy-to-follow step-by-step instructions for your Tesla.
What you will need
- Tesla Brake Hose
- Tesla Jack Pad Adapter
- Brake Fluid
- Floor Jack
- Jack Stand
- 11mm open-end wrench
Procedure
- Park the Tesla on level ground.
- Loosen the lug nuts on the wheel where you plan to replace the brake hose. Do not remove the lug nuts yet.
- Jack up the vehicle by placing a jack at the lift points. Use a jack pad adapter to prevent damage to the battery.
- Secure the vehicle with jack stands. Do not place jack stands under the car near the battery pack.
- Remove the wheel from the vehicle.
- Place a drain pan under the brake to catch any fluid that will drain out.
- Loosen and remove the bolt that secures the hose to the caliper.
- Remove the 10mm bolt and clamp that secures the hose to the knuckle.
- Loosen the nut that secures the brake line to the brake hose. Counter-hold it to loosen.
- Slide out the U-Clip and remove the hose from the vehicle.
- Reinstall the new brake hose in reverse order.
- Open the hood by pressing OPEN on the screen inside your Tesla.
- Remove the plastic cover in front of the windshield by lifting it up. It is held in place with several plastic retainers. It does not have any screws.
- Clean the cap and area around the reservoir with a clean cloth before you open it to prevent any dirt or debris from entering the reservoir.
- Remove the cap and add the recommended brake fluid. The recommended fluid is printed on the top of the reservoir. The recommended fluid in a 2018 Tesla Model 3 is DOT 3.
- Loosen the bleed valve at the brake caliper.
- Have a friend press the brake pedal several times until brake fluid drips from the bleed valve.
- Tighten the bleed valve while your friend keeps the brake pedal pressed, and let it drip brake fluid. You may have to repeat this procedure a few times.
Use a jack pad adapter to prevent damage to the battery. 
That’s it. Replacing the brake hose on a Tesla is relatively easy and only takes about an hour.
Start the procedure by bleeding the brake caliper furthest from the driver when bleeding the brake system. This means you should bleed the calipers on vehicles with the steering wheel on the left: 1. right rear, 2; left rear, 3; right front, 4; left front.
