2
Check the brake calipers for proper operation and signs of sticking.
3
Inspect the suspension components for wear or misalignment.
4
Measure rotor thickness and check for warping or uneven surfaces.
5

Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a level surface.
Wear safety glasses and gloves for protection.
Disconnect the battery to avoid any electrical issues.

2. Lift the Vehicle

Use a hydraulic jack to lift the vehicle and secure it with jack stands.
Remove the wheel to access the brake assembly.

3. Inspect and Replace Brake Components

Check Brake Pads:
- Remove the caliper bolts using a socket set (typically 12mm or 14mm).
- Slide the caliper off the rotor, supporting it to avoid straining the brake line.
- Remove the brake pads and inspect them for uneven wear.
Replace Brake Pads (if worn unevenly):
- Install new brake pads (ensure they match the original specifications).
- Apply anti-squeal lubricant on the backing of the new pads (if applicable).

4. Inspect and Service Brake Calipers

Caliper Inspection:
- Check for corrosion or damage on the caliper.
- Ensure the caliper slides freely on its mounting pins.
Caliper Service (if necessary):
- Clean the caliper slides and apply fresh grease.
- Replace caliper seals if they show signs of wear or leaks.

5. Check Suspension and Alignment

Inspect control arms, bushings, and struts for signs of wear or damage.
If misalignment is detected, perform a wheel alignment to ensure proper tracking.

6. Reassemble and Test

Reinstall the brake caliper and secure it with bolts to the manufacturer's torque specification (typically around 25-30 Nm).
Reinstall the wheel and lower the vehicle.
Reconnect the battery.
