SIGNS YOU NEED TO BLEED YOUR BRAKES

How to Bleed BrakesBleeding brakes isn’t a routine repair, which is why more questions tend to surround it. The most common symptom a driver may notice if they need to bleed their brakes is a spongy, soft sensation to the pedal, and the need to apply more pressure to get the same brake response. This is often following a brake repair, like replacing the pads.

What does this all mean? Before they were replaced, your brake pads likely wore down too much and ran the fluid in your brake system down very low. Now when you apply brake pressure at the pedal, air, instead of fluid, is getting added to your car’s brake lines, causing a squishy pedal feel.

STEP BY STEP SOLUTION

In order to bleed your car’s brakes, you’ll need to make sure you have the following components close at hand:

  • your car’s owner’s manual
  • a helper
  • 16 ounces of fresh brake fluid, preferably from unopened cans
  • a box-end wrench
  • 1 turkey baster, a piece of aquarium tubing, and a clear plastic squeeze bottle
  • 1 bucket and a clean microfiber cloth
  • a 1×4 plywood plank

Steps 1-5: Changing the Brake Fluid

Find your brake’s bleeder valves and using your wrench, loosen the valve’s bolts (keep the valves themselves closed).

Next, find the master cylinder reservoir and take off its cap. Using the turkey baster, siphon out as much brake fluid as you can from the cylinder, squeezing the old fluid into your bucket. Set aside. Use your cloth to wipe out any sediment in the bottom of the reservoir. Then, add clean brake fluid to the master cylinder, filling to the full line. Secure the cap.

Steps 6-10: Bleeding Brakes

Dispense a small amount of fresh brake fluid into the plastic squeeze bottle. Locate the bleeder bolt from the back-right wheel. Attach one end of the plastic tubing to the bleeder bolt, and the other to the squeeze bottle.

Next, put your piece of plywood under the brake pedal and get your helper behind the wheel. Instruct them to apply pressure to the brake as they usually would while coming up to a stop sign. When the pedal’s down fully, tell them to give you a signal.

On the signal from your helper, turn the bleeder bolt a quarter turn to the left. You should see old fluid transfer through the tubing and into the bottle. When the fluid stops coming through, close the valve and have your helper take their foot off the pedal.

Repeat Steps 6-10 While Adding Fresh Fluid to the Master Cylinder

Repeat the steps above for the wheel at hand until fresh fluid enters the bottle. Once the back-right wheel is complete, repeat for the remaining wheel positions.
