Solution

1. Preparation

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

2. Inspect and Replace Brake Fluid

Sub-steps:
1. Remove the master cylinder cap and inspect the brake fluid condition; it should be clear and at the appropriate level.
2. If the fluid is dirty or low, bleed the brake system and replace with new DOT 3 or DOT 4 brake fluid.
Tools Required: Brake fluid, funnel, turkey baster (optional for fluid removal).

3. Inspect and Replace Brake Pads and Rotors

Sub-steps:
1. Remove the wheel to access the brake components.
2. Unbolt the caliper and support it without stretching the brake line.
3. Remove the old brake pads and inspect the rotors for grooves or warping.
4. If necessary, replace the rotors with new ones and install new brake pads according to manufacturer specifications.
5. Reassemble the caliper and wheel, ensuring all bolts are torqued to the manufacturer's specifications.
Tools Required: Socket set, torque wrench, brake cleaner.

4. Inspect and Replace Brake Booster (if necessary)

Sub-steps:
1. Locate the brake booster and check for vacuum leaks or physical damage.
2. If a failure is detected, unbolt the brake booster from the firewall and disconnect the master cylinder.
3. Install the new brake booster and reconnect the master cylinder, ensuring all connections are secure.
Tools Required: Wrench set, screwdriver, vacuum gauge (optional).

5. Final Assembly

Sub-steps:
1. Refill the master cylinder with new brake fluid.
