Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to avoid electrical issues during work.

Tools Required:

Brake fluid
Brake bleeder kit
Wrench set

2. Inspect and Replace Brake Fluid

Sub-step 1: Open the hood and locate the brake master cylinder.
Sub-step 2: Check the fluid level; if low, fill it with the appropriate DOT 3 or DOT 4 brake fluid.
Sub-step 3: If the fluid is contaminated (dark or murky), proceed to replace it.
Sub-step 4: Siphon out old brake fluid from the reservoir and refill it with new fluid.

3. Bleed the Brake System

Sub-step 1: Start at the wheel furthest from the master cylinder (right rear).
Sub-step 2: Attach a clear hose to the bleeder screw on the brake caliper.
Sub-step 3: Have an assistant press the brake pedal several times and hold it down.
Sub-step 4: Open the bleeder screw to release air and old fluid, then close it before the pedal is released.
Sub-step 5: Repeat for each wheel in the order: right rear, left rear, right front, left front.
Sub-step 6: Check the fluid level in the master cylinder frequently to avoid introducing more air.

4. Inspect and Replace Brake Components (if necessary)

Sub-step 1: If sponginess persists, inspect brake pads and rotors for wear.
Sub-step 2: Replace worn brake pads and resurfacing or replacing rotors as needed.
Sub-step 3: Reassemble the brake components and torque the caliper bolts to manufacturer specifications.
