Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent electrical issues while working.

2. Inspect and Replace Brake Rotors

Tools Required: Socket set, torque wrench, brake cleaner
Remove the wheel using a socket set.
Inspect the brake rotor for warping using a dial indicator.
If warped, remove the caliper (unbolt it using the socket set) and hang it securely without stressing the brake line.
Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
Clean the hub surface with brake cleaner to ensure proper contact with the new rotor.
Install the new rotor, securing it with retaining screws if applicable, and torque to manufacturer specifications (typically around 100-120 ft-lbs).

3. Replace Brake Pads

Tools Required: Brake pad spreader, socket set, torque wrench
Remove the old brake pads from the caliper bracket.
Use a brake pad spreader to compress the caliper piston fully.
Install new brake pads into the caliper bracket.
Reattach the caliper over the new pads and torque bolts to manufacturer specifications (usually around 25-30 ft-lbs).

4. Wheel Alignment and Balance

Tools Required: Alignment machine (may require professional assistance)
After reassembling the wheel and brakes, take the vehicle to a professional for wheel alignment and balance if needed.
