Affected Component

Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery when working on the braking system.
•Ensure the vehicle is securely lifted and supported before working underneath it.

Symptoms

•Shaking or vibrating sensation through the steering wheel or vehicle body when brakes are applied
•Pulsation felt in the brake pedal
•Increased stopping distance
•Uneven wear on brake pads or rotors
•Possible noise from braking components (squeaking or grinding)

Diagnostic Steps

1
Inspect brake rotors for warping or uneven surfaces using a dial indicator.
2
Check brake pad thickness to confirm if they are worn beyond the manufacturer's specifications.
3
Examine the brake calipers for sticking or malfunctioning.
4
Inspect wheel bearings for play or wear that could contribute to vibrations.
5
Check tire balance and alignment to rule out issues unrelated to the braking system.
6
Scan for any relevant error codes that may indicate electronic braking system problems.

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

•Lug wrench
•Jack and jack stands
•Socket set
•Torque wrench
•Dial indicator (for rotor inspection)
•Caliper tool or C-clamp

Parts Required

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat, stable surface.
Engage the parking brake and wear safety gloves and goggles.

2. Remove Wheels

Loosen the lug nuts on the front wheels using a lug wrench.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheels.

3. Inspect and Replace Brake Components

a. Inspect Brake Rotors

Check for warping or uneven wear on the rotors.
If warped, proceed to replace them.
Use a dial indicator to measure run-out; if greater than the manufacturer's specification, replace.

b. Replace Brake Pads

Remove the caliper bolts using a socket wrench and slide the caliper off the rotor.
Remove the old brake pads from the caliper bracket.
Apply anti-squeal lubricant to the back of new brake pads and install them into the caliper bracket.

c. Reinstall Caliper

Compress the caliper piston using a caliper tool or C-clamp to accommodate the new pads.
Place the caliper back over the new pads and secure it with the caliper bolts to the manufacturer’s torque specifications.

4. Reinstall Wheels and Lower Vehicle

Place the wheels back onto the hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and tighten the lug nuts to the manufacturer’s torque specifications in a crisscross pattern.

5. Test Drive

Carefully test drive the vehicle to ensure the shaking has been resolved.
