How to Bleed Brakes

If your vehicle's brakes are feeling squishy, it could mean there's air in the line that needs to come out. This is typically done through bleeding the brakes.

Drivers in Bowling Green, Toledo, and Napoleon can learn how to bleed brakes with this helpful article from Al Smith Chrysler Dodge Jeep Ram.

How to Bleed Brakes

Bleeding your brakes requires a brake bleeder wrench, brake fluid, a jar, and a helper.

During this process, air can get into the anti-lock braking system, brake assist, or electronic brakeforce distribution, which can be hazardous to these components. If you're unsure, it's always best to have a service technician bleed your brakes.

Here's how to bleed your brakes:

  1. Find the nozzle marked brake bleeder screw. This should be located behind the brakes. It may be helpful to have your car jacked up.
  2. Choose the wrench that fits correctly, then loosen the screw. Bleeder wrenches are specially designed to fit the bleeder screw and will prevent damage to the head of the bleeder screw. If it's stuck, use a lubricant to loosen it up.
  3. Place a piece of hose over the bleeder screw and put the other end in a jar. Fill the jar with enough brake fluid to completely cover the end of the hose.
  4. Have your helper press your brake pedal down repeatedly. Tell them to say down when they're pressing it down, so you're aware of what's happening. If the vehicle is jacked, make sure there's a block in the direction the car would be likely to roll if it fell, and the tires are beneath the car, so it will just bounce if it slips off the jack.
  5. After your helper has pumped the pedal and is pressing on the pedal, open the screw. Brake fluid will spray out, and if air is in the lines, you'll see air bubbles in the fluid.
  6. While your helper has the brake pedal depressed, tighten the screw. If you fail to perform this step, air will simply suck back into the brake lines once the pedal releases.
  7. Repeat this process until the air bubbles are no longer seen in the fluid.
  8. Open the master cylinder and refill with brake fluid until Full.
  9. Repeat this with your brakes until the air is out of the brake line.
  10. Don't forget to put brake fluid back into the master cylinder after bleeding the brakes.
  11. After getting the brake fluid level in the master cylinder back to full, drive your car around. The brakes shouldn't feel spongy anymore, but if they do, repeat the brake bleeding process again.
