Diagnostic Steps

1
Inspect the brake pads visually through the wheel spokes for thickness.
2
Check for any abnormal noises during a test drive when braking.
3
Measure the brake pad thickness using a caliper or ruler.
4
Inspect the brake rotors for scoring or damage.
5
Check the brake fluid level in the master cylinder reservoir.

Solution

Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, brake pad removal tool, brake cleaner, torque wrench.
Safety Warnings: Always ensure the vehicle is on a flat surface and the parking brake is engaged before starting work. Disconnect the battery before working on any electronic components.

2. Lift the Vehicle

Loosen the lug nuts on the wheel where brake pads will be replaced.
Use a jack to lift the vehicle and secure it on jack stands.
Remove the wheel by fully unscrewing the lug nuts.

3. Remove the Brake Caliper

Locate the caliper mounting bolts and remove them using the socket set.
Carefully slide the caliper off the rotor. Do not let it hang by the brake line; secure it with wire or a bungee cord.
Remove the old brake pads from the caliper bracket.

4. Inspect and Clean

Inspect the caliper and rotor for wear or damage.
Clean the caliper and rotor surfaces with brake cleaner to remove any dust or debris.

5. Install New Brake Pads

Apply a thin layer of brake grease to the back of the new brake pads to prevent squeaking.
Position the new brake pads into the caliper bracket.
Reinstall the caliper over the new pads and secure it with the mounting bolts. Torque the bolts to manufacturer specifications (typically around 25-35 ft-lbs).

6. Reassemble and Test

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and tighten the lug nuts to the specified torque (usually around 80-100 ft-lbs).
Pump the brake pedal a few times to seat the brake pads properly.
