Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety gloves and goggles for protection.

2. Check and Replenish Brake Fluid

Sub-steps:
1. Open the hood and locate the brake master cylinder.
2. Check the brake fluid level; if low, add the recommended brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).
3. Close the master cylinder cap securely.

3. Bleed the Brake System

Sub-steps:
1. Locate a helper to assist with the bleeding process.
2. Starting from the brake furthest from the master cylinder (usually the rear passenger side), use a brake bleeder kit or a clear hose and catch container.
3. Have the helper press the brake pedal several times and hold it down.
4. Open the bleeder valve on the caliper to allow fluid to escape; close the valve once the pedal is pressed down.
5. Repeat this process until no air bubbles are seen in the fluid stream and the fluid runs clear.
6. Move to the next brake and repeat until all brakes have been bled (order: RR, LR, RF, LF).
7. Ensure to check the brake fluid level during this process and top off as needed.

4. Inspect and Tighten Components

Sub-steps:
1. Visually inspect the brake pads, calipers, and rotor surfaces for proper alignment.
2. Ensure all mounting bolts and caliper brackets are properly torqued to manufacturer specifications (typically around 20-30 ft-lbs for caliper bolts).
3. If any components are found loose, tighten them accordingly.
