Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to avoid electrical issues during repair.

2. Inspect and Replace Brake Fluid

Sub-steps:
1. Locate the master cylinder reservoir and remove the cap.
2. Check the brake fluid level and condition; if it appears dark or contaminated, proceed to replace it.
3. Use a turkey baster or brake fluid siphon to remove old fluid from the reservoir.
4. Refill with new brake fluid as per manufacturer specifications (DOT 3 or DOT 4).
Tools Required: Turkey baster or siphon, brake fluid, funnel.

3. Bleed Brake System

Sub-steps:
1. Starting with the wheel farthest from the master cylinder (right rear), attach a clear hose to the bleeder screw on the brake caliper.
2. Place the other end of the hose into a container to catch old brake fluid.
3. Have an assistant pump the brake pedal several times and hold it down.
4. Open the bleeder screw to release air and fluid, then close it before the pedal is released.
5. Repeat until no air bubbles appear in the fluid.
6. Move to the left rear, right front, and then left front, following the same procedure.
Tools Required: Bleeder wrench, clear hose, container for fluid.

4. Check and Replace Brake Components

Sub-steps:
1. Inspect brake pads and rotors for wear; replace if pads are worn down to the wear indicator or rotors are scored.
2. If necessary, remove the caliper by loosening the mounting bolts and sliding it off the rotor.
3. Replace the brake pads and reassemble the caliper.
4. Torque the caliper bolts to manufacturer specifications.
Tools Required: Socket set, torque wrench, brake cleaner.
Safety Warnings: Ensure the vehicle is securely supported on jack stands before working on brakes.
