Do your brakes feel spongy? Does the brake pedal travel all the way to the floor? How long has it been since you last changed your brake fluid (hint: it should be done every 2-3 years!)?
In this post we walk through the steps to quickly and easily flush out the old brake fluid and replenish it with fresh stuff!

This is a pretty easy maintenance item to perform on your vehicle, it will take you about an hour or two depending on how quickly you can take tires on and off. If you take your Toyota Corolla to a shop, a brake fluid flush will cost you about $100-200.
Tools and Supplies:
- 8mm box-end wrench
- DOT3 or DOT3&4 Compatible brake fluid
- rubber tubing (preferably transparent)
- empty bottle (preferably transparent)
- a partner who is good a following directions…
Easy Steps for Flushing Brake Fluid
Okay, we’re ready to go! Follow these steps to bleed the brakes.
Step 1: Remove the tire from the brake furthest from the brake master cylinder.
This is the rear passenger’s side tire. Use a jack and be sure to use jack-stands for safety purposes. Jack up the vehicle and remove the tire. This will provide access to the brake bleeder screw, which is what we want.
(Here is a shot of the old brake fluid, hint: it shouldn’t be brown…)
Step 2: Locate the Bleeder Screw and Attach the Tubing.
Locate the brake bleeder screw, looks kind of like a grease zirk, if you know what those look like. Put your 8mm box-end wrench on there. Then put the clear tubing onto the nipple. I only had black tubing, so that can work in a pinch, however transparent tubing is better so that you can see if there are any bubbles in the fluid.
Put the other end of the tube into a clear plastic collection vessel, like an empty water bottle.
Step 3: Apply pressure to the Brake Pedal and Open the Bleeder Screw.
Ask your partner to apply pressure to the brake pedal and hold it.
While your partner is applying pressure to the brake pedal, open the bleeder screw by turning it counter-clockwise. I found that a 1/4 turn was enough.
Brake fluid will begin to flow out of the tube. Your partner will notice that their foot begins to go down toward the floor.
Step 4: Close the Bleeder Screw and Release the Brake Pedal.
When the brake fluid coming out of the tube begins to slow down, close the bleeder screw.
When the bleeder screw is closed, your partner can release the brake pedal.
Step 5: Repeat Steps 3 and 4 Several Times, Keeping an Eye on the Brake Fluid Level.
Every 2-3 times you pump fluid out of the brake system, check the brake fluid reservoir. Do not let the level drop below the minimum mark, or you may begin to introduce air bubbles into the system!
Repeat this process 10-15 times per brake.
Step 6: Add Brake Fluid to the Max Fill Line.
Don’t leave the cover off the brake fluid reservoir or the brake fluid bottle for too long. Brake fluid will suck up moisture if exposed to the air too long.
Step 7: Repeat the Same Procedure for the Rest of the Brakes.
The correct order is to go from the Passenger’s side rear tire, to the Driver’s side rear tire, to the Passenger’s side front tire, to the Driver’s side front tire.
