Diagnostic Steps

1
Inspect brake pads for wear and thickness using a caliper gauge.
2
Check brake discs (rotors) for scoring, warping, or damage.
3
Examine brake calipers for proper operation and any signs of sticking or binding.
4
Inspect brake lines for leaks or damage.
5

Solution

1. Preparation

Gather tools and materials: socket set, torque wrench, brake cleaner, brake pads, rotors (if necessary), and safety gear.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brakes are problematic.
Secure the vehicle with jack stands to ensure stability.

3. Remove Wheel

Use a socket set to remove the lug nuts and take off the wheel to access the brake components.

4. Inspect and Replace Brake Pads

Inspect: Remove the caliper bolts using the socket set and slide the caliper off the rotor. Check the brake pads for wear.
Replace: If pads are worn down to the wear indicator, replace them:
- Remove the old pads.
- Apply brake lubricant to the backing of the new pads to prevent noise.
- Insert the new pads into the caliper bracket.

5. Inspect and Replace Brake Rotors (if necessary)

Check the rotor for scoring or damage. If damaged:
- Remove the caliper bracket and rotor.
- Clean the hub surface with brake cleaner.
- Install the new rotor, ensuring it is seated correctly.
- Reattach the caliper bracket.

6. Reassemble and Lower Vehicle

Reinstall the caliper over the new pads and torque the caliper bolts to manufacturer specifications (usually 20-30 ft-lbs).
Reattach the wheel and torque the lug nuts in a star pattern to the specified torque (typically 100-140 ft-lbs).
Lower the vehicle back to the ground.
