Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure vehicle is on a flat surface and engage the parking brake.
Elevate the vehicle using a jack and secure it with jack stands.

2. Inspect and Replace Brake Pads

Remove the wheel to access the brake assembly.
- Tools Required: Lug wrench, jack, jack stands.
Remove the caliper by unscrewing the caliper bolts.
- Tools Required: Socket set.
Slide the caliper off the rotor and hang it securely (do not let it hang by the brake line).
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are properly seated in the caliper bracket.

3. Inspect and Replace Brake Rotors (if needed)

Check the thickness of the rotors using a micrometer.
If rotors are below specifications or damaged, remove them by unscrewing the retaining screws or caliper bracket (if applicable).
- Tools Required: Torque wrench, socket set.
Install new rotors, aligning them properly and securing with the retaining screws.
- Torque Specifications: Follow manufacturer specifications for rotor installation torque.

4. Bleed Brake System

Locate the brake bleeder valve on each caliper.
Using a helper, have them depress the brake pedal while you open the bleeder valve, allowing air and old fluid to escape.
Close the valve before the helper releases the brake pedal to prevent air intake.
Repeat this process until clear, bubble-free fluid is expelled from each caliper.
- Tools Required: Brake bleeder kit or clear tubing, brake fluid.
