Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety.

2. Inspect and Replace Brake Rotors

Tools Required: Socket set, torque wrench, brake rotor puller (if needed).
Remove the wheel to access the brake assembly.
Inspect the rotors for warping using a dial gauge or straight edge.
If warped, remove the rotors by unscrewing the caliper bracket bolts and sliding the rotor off.
Install new or resurfaced rotors, ensuring they are clean and free of debris.
Torque the rotor mounting bolts to the manufacturer's specifications.

3. Replace Brake Pads

Remove the caliper by unscrewing the caliper mounting bolts.
Slide the caliper off the rotor and support it (do not let it hang by the brake line).
Remove old brake pads from the caliper bracket.
Install new brake pads, applying brake grease where necessary on the backing plates.
Reattach the caliper and torque the mounting bolts to the specified values.

4. Check Brake Calipers

Inspect the calipers for any signs of damage or sticking.
If necessary, rebuild or replace the calipers based on the inspection findings.

5. Wheel Alignment and Balance

After reassembling the brake components, check the wheel alignment and balance.
Adjust or balance the wheels as needed to ensure even tire wear and handling.
