Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Inspect and Replace Brake Fluid

Tools Required: Brake fluid, funnel, clean cloth
Remove the master cylinder reservoir cap.
Check the brake fluid level. If low, top off with the correct type of brake fluid (DOT 3 or DOT 4).
Clean the reservoir cap and surrounding area before replacing it.

3. Bleed the Brake System

Tools Required: Brake bleeder kit or clear tubing, catch container
Start with the brake furthest from the master cylinder (usually the right rear).
Attach the tubing to the bleeder valve on the brake caliper.
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve to allow air and fluid to escape, then close it while the pedal is held down.
Repeat this process until no air bubbles are present in the fluid.
Proceed to the left rear, right front, then left front in the same manner.
Refill the master cylinder reservoir as needed during the process.

4. Inspect and Replace Brake Components

Tools Required: Socket set, torque wrench, brake cleaner, new brake pads/rotors if needed
Remove the wheel and inspect the brake pads for thickness. If they are worn below the minimum thickness, replace them.
If rotors are warped or excessively worn, replace them as well.
Clean the caliper and rotor surfaces with brake cleaner before installation.
Reassemble the brake components and torque all bolts to manufacturer specifications.

5. Final Assembly and Testing

Tools Required: Torque wrench
Reinstall the wheel and torque the lug nuts to specified values.
Test the brake pedal for firmness and ensure it does not sink when pressed.
Lower the vehicle and perform a short test drive to verify proper brake function.
