Affected Component

Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on brake systems.
•Allow brakes to cool before inspection or repairs to avoid burns.

Symptoms

•Noticeable difference in thickness between the inner and outer brake pads
•Increased brake noise (squealing or grinding)
•Vibration or pulsation during braking
•Pulling to one side when braking
•Increased stopping distance

Diagnostic Steps

1
Inspect the brake pads visually for wear patterns and thickness.
2
Check brake caliper operation to ensure it is not sticking or seized.
3
Inspect the brake rotor for warping or uneven surface.
4
Examine brake hardware (shims, clips) for proper installation and condition.
5
Verify that the brake lines are not pinched or damaged, affecting fluid pressure.

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 flat surface and the parking brake is engaged.
Wear safety glasses and gloves.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts using a socket set.
- Slide the caliper off the rotor, being careful not to stretch the brake line.
- Inspect the pads for uneven wear; note which side is more worn.
Replace Brake Pads (if necessary):
- Remove the old pads from the caliper bracket.
- Compare new pads to old pads for correct fitment.
- Install new pads in the same position as the old ones, ensuring proper orientation.

4. Check and Replace Calipers (if necessary)

Inspect the calipers for signs of sticking or corrosion.
If calipers are faulty, remove the caliper from the bracket.
- Disconnect brake line (use a line wrench to avoid rounding off fittings).
- Install the new caliper, ensuring proper torque specifications for bolts.
- Reconnect the brake line and check for leaks.

5. Reassemble and Test

Reinstall the caliper onto the rotor and tighten the caliper bolts to the manufacturer’s torque specifications.
Reattach the wheel and hand tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a crisscross pattern.
Pump the brake pedal to ensure proper pad seating before driving.
