Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety glasses and gloves.

2. Lift the Vehicle

Tools Required: Jack, jack stands, wheel chocks.
Securely lift the vehicle using a jack and place jack stands under the frame.
Remove the wheels to access the brake components.

3. Inspect and Replace Brake Pads

Tools Required: Socket set, torque wrench, brake cleaner.
Remove the caliper bolts and carefully detach the caliper from the rotor.
Inspect the brake pads for wear; if they are uneven, replace them with new pads.
- Torque caliper bolts to manufacturer specifications (typically around 25-30 Nm).
Apply brake lubricant to the back of the pads and on the caliper slides.

4. Inspect and Service Brake Calipers

Check the calipers for proper operation; if they are sticking, clean or replace as necessary.
Ensure the caliper slides are free of rust and debris, and apply lubricant if needed.

5. Inspect Suspension and Alignment

Examine suspension components (control arms, bushings, etc.) for wear that could affect brake alignment.
If any components are worn, replace them as necessary.
Perform a wheel alignment to ensure proper tracking.

6. Reassemble and Test

Reinstall the wheels and lower the vehicle.
Pump the brake pedal to ensure pads contact the rotor properly before driving.
Test drive the vehicle to check for braking performance and any abnormal noises.
