Diagnostic Steps

1
Inspect brake pads visually for wear indicators or damage.
2
Check brake rotors for scoring or uneven wear.
3
Examine brake calipers for proper operation and any signs of sticking.
4
Remove wheel and inspect for debris or dust buildup in the brake assembly.

Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a level surface.
Wear safety goggles and gloves for protection.
Disconnect the vehicle's battery to ensure safety during brake work.

2. Remove Wheel

Use a jack to lift the vehicle and secure it on jack stands.
Remove the wheel using a socket set (typically 19mm for lug nuts).

3. Inspect and Replace Brake Pads

Sub-step 1: Remove the caliper bolts using a socket set (usually 12mm or 14mm).
Sub-step 2: Carefully slide the caliper off the rotor and support it with a bungee cord to avoid stressing the brake line.
Sub-step 3: Remove the old brake pads from the caliper bracket.
Sub-step 4: Compare the old pads with new ones to ensure correct size.
Sub-step 5: Lubricate the backing of the new pads with brake grease to reduce noise.
Sub-step 6: Install new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-step 1: Check the rotor for any scoring or warping.
Sub-step 2: If replacement is needed, use a rotor puller to remove the rotor from the hub.
Sub-step 3: Install new rotors, ensuring they are clean and free of oil.

5. Reassemble Brake Components

Reattach the caliper over the new pads and secure it with the caliper bolts. Torque the bolts to the manufacturer’s specifications (typically around 25-30 ft-lbs).
Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications (usually around 100-110 ft-lbs).

6. Final Checks

Reconnect the battery and check the brake fluid level, topping off if necessary.
Pump the brake pedal several times to ensure proper brake engagement and reset the caliper pistons.
