Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Check and Replace Brake Fluid

Sub-steps:
1. Open the hood and locate the brake fluid reservoir.
2. Remove the cap and check fluid level; top up with the correct type of brake fluid (DOT 3 or DOT 4 as specified).
3. If the fluid appears discolored or contaminated, proceed to replace the fluid.

Tools Required:

Brake fluid (DOT 3 or DOT 4)
Funnel

3. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Inspect the brake pads and rotors for wear; replace if pads are less than 3mm thick or rotors are warped.
3. Replace brake pads and rotors as necessary, ensuring to torque bolts to manufacturer specifications (typically around 80-100 ft-lbs for caliper bolts).

Tools Required:

Lug wrench
Socket set
Torque wrench

4. Bleed the Brake System

Sub-steps:
1. Starting with the wheel farthest from the master cylinder, attach a clear hose to the brake bleeder valve.
2. Have an assistant pump the brake pedal until it feels firm, then hold it down.
3. Open the bleeder valve to release air and fluid; close the valve before the pedal is released.
4. Repeat until no air bubbles appear in the fluid.
5. Repeat for the remaining wheels in the proper sequence (farthest to closest).

Tools Required:

Brake bleeder kit
Clear tubing
