Solution

1. Preparation

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

2. Inspect and Replace Brake Pads

Remove the wheel using a socket set.
Inspect brake pads for thickness; if less than 3 mm, replace.
To replace, remove the caliper bolts and slide the caliper off.
Replace old pads with new ones, ensuring they fit snugly.
Reinstall the caliper and torque bolts to manufacturer specifications (typically around 25-30 ft-lbs).

3. Inspect and Resurface or Replace Rotors

Measure rotor thickness using a micrometer; if below the minimum specification, replace.
If rotors are within spec but warped, use a rotor resurfacing machine to smooth the surface.
After resurfacing, clean the rotor with brake cleaner to remove dust and debris.

4. Check and Replace Brake Calipers (if necessary)

Inspect the caliper for any signs of leakage or sticking.
If defective, remove the caliper from the mounting bracket.
Install the new caliper, ensuring that the brake line is properly connected and not twisted.
Torque the caliper bolts to specification.

5. Reassemble and Test

Reinstall the wheel and torque lug nuts to specification (typically 75-80 ft-lbs).
Reconnect the battery and start the vehicle.
Test brake functionality by applying the brakes gently at low speed to ensure no vibrations occur.
