Check the condition of the brake rotors for scoring or warping.
3
Evaluate the brake fluid level and quality in the master cylinder reservoir.
4

Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, brake pad gauge, brake cleaner, torque wrench, and safety glasses.
Sub-steps:
1. Park the vehicle on a level surface and engage the parking brake.
2. Loosen the lug nuts slightly while the vehicle is still on the ground.
3. Lift the vehicle using a jack and secure it with jack stands.
4. Remove the wheel to access the brake assembly.

2. Inspect Brake Components

Sub-steps:
1. Visually inspect both brake pads for wear; a minimum thickness of 3mm should be maintained.
2. Check the rotors for any signs of wear, scoring, or warping.
3. If one pad is worn significantly, assess the other pad's condition; if the other pad is also close to the minimum thickness, it is recommended to replace both.

3. Replace Brake Pads

Sub-steps:
1. If replacement is needed, remove the caliper bolts using the socket set.
2. Carefully slide the caliper off the rotor, avoiding damage to the brake line.
3. Remove the worn brake pads from the caliper bracket.
4. Install new brake pads into the caliper bracket, ensuring they are seated properly.
5. Compress the caliper piston using a brake caliper tool to allow the caliper to fit over the new pads.

4. Reassemble and Test

Sub-steps:
1. Reattach the caliper over the new brake pads and torque the caliper bolts to manufacturer specifications (usually around 25-30 ft-lbs).
2. Reinstall the wheel and hand-tighten the lug nuts.
3. Lower the vehicle and torque the lug nuts to the manufacturer's specifications (typically 76-83 ft-lbs).
4. Pump the brake pedal a few times to seat the pads properly before driving.
