Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a flat surface and the ignition is off.
Tools Required: Socket set, brake bleeder kit, jack and jack stands, wrench set, brake fluid.
Safety Warnings: Wear gloves and safety goggles to protect against brake fluid exposure.

2. Inspect and Replace Brake Fluid

1.1 Open the hood and locate the master cylinder reservoir.
1.2 Check the brake fluid level; if low, inspect for leaks.
1.3 If the fluid is contaminated (dark or has particles), drain the reservoir and replace with new brake fluid (DOT 3 or DOT 4, as specified).

3. Bleed the Brakes

3.1 Connect the brake bleeder kit to the bleeder valve on the farthest brake caliper from the master cylinder (usually the rear passenger side).
3.2 Have an assistant press the brake pedal while you open the bleeder valve to release air and old fluid.
3.3 Close the valve before your assistant releases the brake pedal. Repeat until fluid is clear and free of air bubbles.
3.4 Move to the next caliper (rear driver side, then front passenger, and finally front driver side) and repeat the bleeding process.
3.5 Continuously monitor the master cylinder reservoir, topping off with fluid as necessary.

4. Inspect and Replace Brake Components (if necessary)

4.1 If sponginess persists, inspect brake pads and rotors for wear.
4.2 Replace worn brake pads with new ones, ensuring proper fit and alignment.
4.3 If rotors are warped or damaged, replace them as well.
4.4 Reassemble all components, ensuring all bolts are torqued to manufacturer specifications.

5. Recheck Brake Function

5.1 After completing repairs, press the brake pedal several times to establish a firm feel.
5.2 Test drive the vehicle at low speeds to ensure proper braking performance.
