Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Wear gloves and safety glasses.
•Disconnect battery before working on electrical systems.
•Allow brake components to cool before handling.

Symptoms

•Steering wheel shakes during braking
•Pulsation felt through the brake pedal
•Vehicle pulls to one side while braking
•Increased stopping distance
•Potential noise during braking (grinding or squeaking)

Diagnostic Steps

1
Inspect brake pads for wear and unevenness.
2
Check brake rotors for warping or thickness variation using a micrometer.
3
Examine wheel bearings for play or wear.
4
Inspect suspension components (control arms, tie rods) for damage or looseness.
5
Verify tire condition and balance.
6
Scan for any error codes related to the brake system using an OBD-II scanner.

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 tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery for safety if working on electrical components.

2. Inspect and Replace Brake Pads

Remove the wheel using a socket set.
Inspect brake pads for thickness; replace if below manufacturer specifications.
Tools Required: Socket set, torque wrench, brake pad spreader.
Safety Warning: Wear gloves and safety glasses.

3. Check and Resurface/Replace Brake Rotors

Remove the brake caliper and hang it safely to avoid straining the brake line.
Take off the rotor and measure its thickness with a micrometer.
If warped, either resurface the rotor (if within specifications) or replace it.
Tools Required: Torque wrench, rotor puller (if necessary).

4. Inspect Suspension and Steering Components

Check control arms, tie rods, and bushings for wear or damage.
Replace any damaged components as needed.
Tools Required: Socket set, torque wrench, pry bar.

5. Check and Balance Tires

Inspect tires for uneven wear and ensure proper inflation.
Balance the tires if necessary or replace if they are worn out.
Tools Required: Tire pressure gauge, tire balancing machine.
