Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on electrical components.
•Allow the vehicle to cool before working on the brake system to avoid burns.

Symptoms

•Vibration felt through the steering wheel when braking
•Shaking felt in the vehicle body
•Uneven wear on brake pads or rotors
•Increased stopping distance
•Possible noise (squeaking or grinding) when braking
•Steering wheel may pull to one side while braking

Diagnostic Steps

1
Inspect brake pads for wear and thickness using a caliper gauge.
2
Check the condition of brake rotors for warping or scoring using a runout gauge.
3
Examine the brake calipers for proper operation and any signs of sticking.
4
Inspect suspension components (e.g., control arms, ball joints) for wear or damage.
5
Ensure that wheel lug nuts are properly torqued to specifications.
6
Test drive the vehicle to replicate the shaking and identify if it occurs at specific speeds or braking conditions.

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 necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery for safety.

2. Remove Wheel Assembly

Using a lug wrench, loosen the lug nuts on the affected wheel.
Lift the vehicle with a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Brake Pads:
- Inspect the brake pads for wear. Replace if the thickness is below manufacturer specifications.
- To replace, remove the caliper bolts, slide off the caliper, and replace the pads.
Brake Rotors:
- Check rotors for warping using a runout gauge. Replace if warping exceeds manufacturer tolerances.
- To replace, remove the caliper bracket, slide off the old rotor, and install a new rotor. Torque the bolts to manufacturer specifications.

4. Reassemble Wheel Assembly

Reattach the brake caliper and torque the bolts to specifications.
Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and use the torque wrench to tighten lug nuts to the manufacturer’s specifications.

5. Final Checks

Reconnect the battery.
Pump the brake pedal to ensure proper brake engagement.
Test the brakes at low speed to ensure the issue is resolved before driving normally.
