Affected Component

Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on brake systems.
•Allow brakes to cool before touching components after use.

Symptoms

•Vibration or shaking felt in the steering wheel when braking
•Pulsation of brake pedal during braking
•Increased stopping distance
•Uneven wear on brake pads or rotors
•Possible noise (squeaking or grinding) when brakes are applied

Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a dial indicator.
2
Check brake pads for thickness and even wear pattern.
3
Examine wheel bearings for play or damage.
4
Inspect suspension components (control arms, tie rods) for wear.
5
Verify tire balance and condition.
6
Scan the vehicle for any ABS-related error codes.

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

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Lift the Vehicle

Use a jack to lift the front of the vehicle and secure it with jack stands.
Remove the front wheels using a socket set.

3. Inspect and Replace Brake Rotors

Inspect:
- Measure rotor thickness using a micrometer to check for wear.
- Check for any signs of warping or scoring.
Replace:
- If warped or below minimum thickness, remove caliper bolts and slide off the caliper.
- Support the caliper using a bungee cord to avoid straining the brake line.
- Remove the rotor by unscrewing the retaining screws and pulling it off.
- Install the new rotor and secure it with screws.
- Reinstall the caliper and torque bolts to manufacturer specifications (usually around 25 Nm).

4. Inspect and Replace Brake Pads

Remove the caliper from the rotor.
Take out the old brake pads and inspect for wear.
If necessary, install new brake pads, ensuring they are seated properly in the caliper bracket.
Apply brake grease on the backing plates of the pads to prevent squeaking.

5. Reassemble and Lower the Vehicle

Reinstall the wheels and torque lug nuts to the specified value (usually around 110 Nm).
Remove the jack stands and lower the vehicle.

6. Test Drive

Start the vehicle and perform a test drive to ensure proper braking function and check for any vibrations.
