Diagnostic Steps

2
Check brake rotor condition for scoring or damage.
3
Examine brake calipers for proper function and any sticking issues.
4
Measure brake fluid level and check for contamination.
5

Solution

1. Preparation

Gather tools and parts: Ensure you have a lug wrench, socket set, brake cleaner, and new brake pads if replacement is necessary.
Safety first: Park the vehicle on a flat surface, engage the parking brake, and use wheel chocks.

2. Wheel Removal

Use a lug wrench to loosen the lug nuts slightly while the vehicle is on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheels.

3. Brake Pad Inspection and Replacement

Remove the brake caliper bolts using a socket wrench.
Carefully lift the caliper away from the rotor without disconnecting the brake line, and support it using a bungee cord or similar device.
Inspect the brake pads for excessive wear. If they are worn down, remove them from the caliper bracket.
If replacing, compare new pads with the old ones to ensure correct fit.
Apply brake lubricant to the back of the new pads to reduce noise and chatter.

4. Rotor Inspection and Resurfacing (if necessary)

Inspect the rotor surface for grooves, scoring, or excessive rust.
If the rotor is damaged, consider resurfacing or replacement.
Clean the rotor surface with brake cleaner to remove any debris or contaminants.

5. Reassembly

Reinstall the caliper over the new brake pads and tighten caliper bolts to manufacturer specifications (typically around 25-30 lb-ft).
Reattach the wheels and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a star pattern to ensure even pressure.
Test the brakes by pressing the pedal a few times to ensure proper seating of the pads.
