Affected Component

Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on the braking system.
•Allow the vehicle to cool down before beginning work to avoid burns from hot components.

Symptoms

•Vibration or shaking felt in the steering wheel when braking
•Pulsation through the brake pedal
•Uneven wear on brake pads or rotors
•Noises such as grinding or squeaking during braking
•Potential pulling to one side while braking

Diagnostic Steps

1
Inspect the brake rotors for warping or uneven wear using a dial indicator.
2
Check brake pad thickness and condition, ensuring they are not worn down.
3
Examine wheel bearings for play or damage using a wheel chock and tug test.
4
Inspect suspension components such as control arms and bushings for wear or damage.
5
Perform a visual inspection of the brake calipers to ensure they are functioning correctly.

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 all necessary tools and parts.
Ensure the vehicle is parked on a level surface, then secure it with wheel chocks.
Disconnect the battery to prevent any electrical issues while working on the brakes.

2. Remove Wheel

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

3. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
- Use a dial indicator to measure rotor runout; replace if warped beyond specifications (typically 0.002 inches).
- If replacing, remove caliper bolts using a socket set and hang the caliper using a bungee cord to avoid stressing the brake line.
- Remove the rotor; if stuck, tap gently with a rubber mallet.
- Install the new rotor, ensuring it's properly seated.

4. Inspect and Replace Brake Pads (if necessary)

Sub-steps:
- Remove the caliper bracket using a socket set.
- Take out the old brake pads and examine their condition.
- Clean the caliper bracket and apply anti-squeal grease to the contact points.
- Install new brake pads, ensuring proper orientation and alignment.

5. Reassemble Components

Sub-steps:
- Reattach the caliper bracket and torque bolts to manufacturer specifications (typically around 25-35 ft-lbs).
- Reinstall the caliper, ensuring it moves freely.
- Reattach the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Torque Lug Nuts

Lower the vehicle from jack stands and remove wheel chocks.
Use a torque wrench to tighten lug nuts to the specified torque (typically 75-90 ft-lbs).
