2
Check brake pad thickness and condition visually.
3
Examine suspension components (e.g., control arms, bushings) for wear or damage.
4
Test brake calipers for proper operation and sticking.
5

Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Loosen the lug nuts on the front wheels.

2. Raise the Vehicle

Using a jack, lift the front of the vehicle and securely support it with jack stands.
Remove the front wheels to access the brake components.

3. Inspect and Replace Brake Rotors

Inspect Rotors
- Check the rotors for warping or uneven wear using a dial indicator or runout gauge.
Replace Rotors if Necessary
- Remove the brake caliper by unbolting it and securing it away from the rotor.
- Remove the rotor by unscrewing any retaining screws or removing the caliper bracket.
- Install new rotors, ensuring they are properly seated.

4. Inspect and Replace Brake Pads

Inspect Pads
- Check the brake pads for thickness and even wear.
Replace Pads if Necessary
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are aligned properly.
- Compress the caliper piston using a brake caliper tool to make space for the new pads.

5. Reassemble and Lower the Vehicle

Reattach the brake caliper over the new pads.
Tighten all bolts to manufacturer torque specifications (typically around 30-40 ft-lbs for caliper bolts).
Reinstall the wheels and torque the lug nuts to the manufacturer specifications.
Lower the vehicle back to the ground.

6. Test Drive

Conduct a test drive to ensure smooth braking and confirm that vibrations have been eliminated.

Tools Required:
