Affected Component

Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always allow the brakes to cool before working on them to prevent burns.
•Use safety glasses and gloves when handling brake components.

Symptoms

•Shaking or vibration felt in the steering wheel while braking
•Pulsating brake pedal when applying brakes
•Uneven wear on brake pads or rotors
•Possible noise from brakes (squeaking or grinding)
•Vehicle pulls to one side during braking

Diagnostic Steps

1
Inspect the front brake rotors for warping using a runout gauge.
2
Check the condition of the brake pads for uneven wear or damage.
3
Examine the brake calipers for proper operation and ensure they are not sticking.
4
Inspect suspension components (tie rods, control arms, and bushings) for wear or damage.
5
Check tire balance and alignment, as they can contribute to shaking during braking.

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

Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery.

2. Inspect and Replace Brake Rotors

Remove Wheel:
- Use a socket set to remove the lug nuts and take off the wheel.
Check Rotor Condition:
- Use a runout gauge to measure for warping. If warped beyond specifications (typically 0.002 inches), replace the rotor.
Remove Brake Caliper:
- Use a socket set to remove caliper bolts and hang the caliper using wire to prevent stress on the brake line.
Remove Rotor:
- If necessary, use a hammer to gently tap the rotor off the hub.
Install New Rotor:
- Align the new rotor with the hub and secure it in place.

3. Replace Brake Pads

Remove Old Brake Pads:
- Slide out the old pads from the caliper bracket.
Install New Brake Pads:
- Place new pads into the caliper bracket ensuring correct orientation.
Reattach Brake Caliper:
- Reinstall the caliper over the new pads and tighten bolts to the manufacturer’s specifications (typically 20-30 Nm).

4. Reassemble and Test

Reattach Wheel:
- Place the wheel back on and tighten lug nuts in a star pattern to the specified torque (typically 80-100 Nm).
Reconnect Battery:
- Reconnect the battery.
Test Drive:
- Conduct a test drive to check for vibrations during braking.
