Solution

1. Preparation

Gather tools and parts required.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal.

2. Remove Wheel

Using a jack, lift the vehicle and secure it with jack stands.
Remove the lug nuts with a socket set.
Take off the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor. Support it with a bungee cord to avoid strain on the brake line.
Inspect the brake pads for wear and replace if necessary.
- If replacing, remove the old pads by sliding them out of the caliper bracket.
- Install new pads in the same position as the old ones, ensuring they are seated properly.

4. Inspect and Resurface/Replace Rotors

Check the rotors for warping or scoring. Use a micrometer to measure thickness.
If the rotors are within spec, they can be resurfaced. If not, replace them.
To replace, remove the rotor by unscrewing any retaining screws and sliding it off the hub.

5. Reassemble Components

Reinstall the caliper over the new pads and rotor.
Torque the caliper bolts to the manufacturer’s specifications (typically around 25-30 ft-lbs).
Reinstall the wheel and lug nuts, tightening them in a crisscross pattern to ensure even pressure.

6. Final Checks

Reconnect the battery terminal.
Pump the brake pedal a few times to seat the pads against the rotors.
Check brake fluid level and top off if necessary.
