1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Gather safety equipment such as gloves and goggles.

2. Inspect and Replace Brake Fluid

Tools Required: Brake fluid, funnel, clean rags.
Check the brake fluid level; if low, top up with the correct type of brake fluid (DOT 3 or DOT 4).
Clean any spilled brake fluid immediately.

3. Bleed the Brake System

Tools Required: Brake bleeder kit, wrench, clean container.
Attach the brake bleeder kit to the brake bleeder valve on each wheel.
Start with the wheel furthest from the master cylinder (right rear).
Pump the brake pedal several times and hold it down.
Open the bleeder valve to release air and fluid; close it before releasing the pedal.
Repeat until no air bubbles are present, then move to the left rear, right front, and finally left front.

4. Inspect and Replace Master Cylinder (if necessary)

Tools Required: Socket set, wrench, brake fluid.
Disconnect the battery before starting.
Remove the master cylinder from the brake booster by loosening the mounting bolts.
Inspect the master cylinder for internal damage; replace if necessary.
Install the new master cylinder and ensure all connections are secure.
Refill the brake fluid reservoir with the appropriate fluid.

5. Inspect Brake Lines and Components

Tools Required: Visual inspection tools, wrenches.
Check all brake lines and hoses for cracks or leaks; replace any damaged components.
Inspect brake calipers and pads for wear; replace if necessary.
