Solution

1. Preparation

Tools Required: Brake bleeder kit, wrench (typically 10mm), clear tubing, brake fluid (DOT 4), safety glasses, and gloves.
Park the vehicle on a level surface and engage the parking brake.
Remove the wheel covering the brake caliper you will start with (usually the rear passenger side).
Ensure the brake fluid reservoir is full.

2. Bleed the Brakes

a. Locate the Bleed Valve

Identify the bleed valve on the brake caliper (usually at the top).

b. Attach Tubing

Place a clear plastic tube over the bleed valve and submerge the other end in a container with brake fluid to catch any expelled fluid.

c. Open the Bleed Valve

Use the wrench to open the bleed valve slightly (about a quarter turn) while an assistant presses the brake pedal.

d. Pump the Brake Pedal

Have your assistant pump the brake pedal several times and hold it down.
While the pedal is held down, open the bleed valve and watch for fluid and air bubbles to escape.

e. Close the Bleed Valve

Once the fluid flow appears steady without air bubbles, close the bleed valve while the pedal is still pressed.
Instruct your assistant to release the brake pedal slowly.

f. Repeat

Repeat the process until clear brake fluid without bubbles is expelled, moving to the next brake caliper in the correct order (typically: right rear, left rear, right front, left front).

3. Finalize

Check the brake fluid reservoir frequently, topping it up as needed to prevent it from becoming empty during the process.
Once all calipers have been bled, ensure all bleed valves are securely closed.
Reinstall the wheel and lower the vehicle.
