Solution

1. Preparation

Gather all necessary tools and parts.
Safely park the vehicle on a level surface and engage the parking brake.
Disconnect the negative terminal of the battery to prevent any electrical issues.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench.
Sub-steps:
1. Loosen lug nuts while the vehicle is on the ground.
2. Raise the vehicle using the jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Rotors

Tools Required: Torque wrench, socket set, rotor puller (if necessary).
Sub-steps:
1. Examine the brake rotors for warping using a dial indicator.
2. If warped, remove the brake caliper by unscrewing the caliper bolts.
3. Slide the caliper off the rotor and support it with a bungee cord to avoid stress on the brake line.
4. Remove the old brake rotor by unscrewing any attaching screws or using a rotor puller.
5. Install the new or resurfaced rotor, ensuring it is seated properly.
6. Reattach the brake caliper and torque bolts to specification (usually around 70-80 ft-lbs).

4. Replace Brake Pads

Tools Required: Brake pad spreader tool, torque wrench.
Sub-steps:
1. Remove the old brake pads from the caliper bracket.
2. Use a brake pad spreader tool to compress the caliper piston back into the caliper housing.
3. Install the new brake pads into the caliper bracket, ensuring they are properly aligned.
4. Reassemble the caliper over the new pads.

5. Reassemble Wheel and Test

Tools Required: Torque wrench.
Sub-steps:
1. Reattach the wheel and hand-tighten the lug nuts.
2. Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications (usually around 100-110 ft-lbs).
3. Reconnect the battery terminal.
4. Test drive the vehicle at low speed to ensure proper brake function and check for pulsation.
