Affected Component

Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always use jack stands when working under a vehicle.
•Allow brakes to cool down before working on them to avoid burns.

Symptoms

•Shaking or vibration felt in the steering wheel or brake pedal when braking
•Increased stopping distance
•Uneven wear on brake pads or rotors
•Possible noise (squeaking or grinding) during braking
•Vehicle pulling to one side while braking

Diagnostic Steps

1
Inspect brake rotors for warping or uneven surfaces using a run-out gauge.
2
Check brake pads for wear and ensure they are properly seated in the caliper.
3
Examine suspension components (e.g., control arms, bushings, struts) for damage or wear.
4
Test brake calipers for proper operation and ensure they are not sticking.
5
Verify wheel alignment and balance to rule out related issues.

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.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Brake Rotors

Tools Required: Jack and jack stands, lug wrench, torque wrench, brake rotor gauge.
Raise the vehicle using the jack and secure it with jack stands.
Remove the wheel using the lug wrench.
Check the rotors for run-out using a run-out gauge; if warped beyond specifications, remove the rotors.
To remove the rotor, unbolt it from the hub using the appropriate socket.
Install new rotors by aligning the rotor with the hub and securing it with bolts to the manufacturer’s torque specifications.

3. Inspect and Replace Brake Pads

Tools Required: Brake pad spreader, socket set.
Remove the caliper by unbolting it from the bracket using a socket.
Carefully slide the caliper off the rotor; do not disconnect the brake line.
Inspect the brake pads; if worn below the minimum thickness, replace them.
Slide new brake pads into the caliper bracket, ensuring proper orientation.
Reinstall the caliper over the new pads and secure it with bolts to the manufacturer's torque specifications.

4. Check Suspension Components

Tools Required: Visual inspection tools, pry bar.
Visually inspect control arms, bushings, and struts for cracks or excessive wear.
Use a pry bar to check for play in the bushings and joints.
Replace any damaged components as necessary to restore proper suspension function.
