Affected Component

Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the 12V battery before performing brake work on electric vehicles.
•Allow the brake system to cool before starting work to prevent burns.

Symptoms

•Brake pedal pulsation or vibration when braking
•Increased stopping distance
•Brake noise (squeaking or grinding)
•Steering wheel shake while braking
•Uneven brake pad wear observed during inspection

Diagnostic Steps

1
Inspect brake rotors for warping using a dial indicator gauge.
2
Check brake pads for uneven wear or damage.
3
Measure rotor thickness and condition; look for signs of scoring or cracks.
4
Verify brake fluid level and condition; ensure it is within specifications.
5
Perform a road test to replicate and evaluate the pulsation occurrence.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly
✓Check for any error codes or warning lights
✓Monitor the vehicle for a few days to ensure the issue does not recur

Prevention Tips

To prevent this issue from occurring again:

•Follow the manufacturer's recommended maintenance schedule
•Address warning signs early before they develop into major issues
•Use quality parts and fluids recommended for your vehicle
•Keep detailed records of all repairs and maintenance

Tools & Equipment Required

•Socket set
•Jack
•Jack stands
•Torque wrench
•Brake cleaner
•Dial indicator gauge

Parts Required

2
Check brake pads for uneven wear or damage.
3
Measure rotor thickness and condition; look for signs of scoring or cracks.
4
Verify brake fluid level and condition; ensure it is within specifications.
5

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear appropriate safety gear (gloves, safety glasses).

2. Remove Wheel

Tools Required: Socket set, jack, jack stands
Loosen the lug nuts slightly while the vehicle is still on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Examine the brake rotor for warping using a dial indicator. If warping exceeds manufacturer specifications (typically 0.002 inches), replace the rotor.
Check the brake pads for even wear; replace any pads that show signs of uneven wear or are below the minimum thickness (usually around 3mm).

4. Replace Rotors and Pads

Tools Required: Torque wrench, brake cleaner, anti-seize compound
Remove the caliper bolts and carefully take off the brake caliper.
Hang the caliper using a bungee cord to avoid straining the brake line.
Remove the old rotor by unscrewing the retaining screws (if applicable) and slide it off the hub.
Install the new rotor, ensuring it is seated properly.
Apply brake cleaner to remove any contaminants from the rotor surface.
Install new brake pads into the caliper bracket.
Reattach the brake caliper over the new pads and rotor.
Torque the caliper bolts to manufacturer specifications (usually around 79-104 Nm, check specifications).

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts in a crisscross pattern to the specified torque (typically around 130 Nm).
Pump the brake pedal to seat the pads against the rotors.
Take the vehicle for a test drive to ensure the pulsation has been resolved.
