⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is on a flat surface and secured with wheel chocks before lifting.
•Wear safety goggles and gloves.

Symptoms

•Warning light for brake system illuminated on the dashboard
•Decreased braking performance or longer stopping distances
•Squeaking or squealing noise when braking
•Vibration or pulsation felt in the brake pedal
•Brake dust buildup on wheels
•Visual inspection shows worn brake pads or uneven wear

Diagnostic Steps

1
Examine the brake pads through the wheel spokes to check for thickness. Pads should be at least 3mm thick.
2
Drive the vehicle and listen for any unusual sounds during braking, such as squeaking or grinding.
3
Use the vehicle's display to check for any brake system warning lights.
4
Assess the responsiveness of the brakes during a test drive, noting any delays or decreases in performance.
5
Check the wheels for excessive brake dust accumulation, which might indicate worn brake pads.
6
Use the Tesla software to check for any diagnostic codes related to the brake system.

Solution

1. Preparation

Tools Required: Jack and jack stands, wheel chocks, torque wrench, socket set, brake pad replacement kit.
Safety Warnings: Ensure the vehicle is on a flat surface and secured with wheel chocks before lifting. Wear safety goggles and gloves.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Remove Brake Caliper

Locate the caliper mounting bolts and use the socket set to remove them.
Carefully slide the caliper off the brake rotor without stretching the brake line.
Support the caliper with a bungee cord or rope to avoid stress on the brake line.

4. Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Compare the thickness of the new pads with the old ones to ensure proper replacement.
Apply brake grease to the back of the new pads to reduce noise.
Insert the new pads into the caliper bracket.

5. Reassemble Components

Compress the caliper piston using a brake caliper tool to allow for the new pads' thickness.
Reattach the caliper over the new pads and tighten the mounting bolts to the manufacturer's torque specifications.
Reinstall the wheel and hand-tighten the lug nuts before lowering the vehicle.

6. Final Checks

Lower the vehicle and torque the lug nuts to the specified value.
Pump the brake pedal a few times to seat the new pads before driving.
