The bleeder screws are located at the back of the wheel cylinders and on the inboard side at the top of the calipers.You will need to loosen these off carefully I believe they are an 8 mm wrench.If they are rusty or have been there a long time you can snap them off if you apply to much force.Once you have them backed off you can let them drip and clear the air or get a friend to help you by doing the following.Have your friend depress the brake pedal slowly to the floor and hold it. While your friend is doing this back off the bleeder screw letting the fluid out and tighten it again when the peddle is depressed all the way. repeat this process on all four wheels OR until you have good brake peddle.Keep a eye on the fluid level in the master brake cylinder and do not let it get low. Best of luck

How to bleed a line


in order to bleed a brake line you will probably need a second person to pump the brakes when the car is off than you need to find the bleeder on the caliper/wheel cylinder it will be towards the top of the caliper/wheel cylinder when you find it make sure you can get it loose than when the bleeder is tight you need someone to pump up the brakes with the car off they need to hold the brakes tight and you need to open the bleeder don't take the bleeder off the pedal should go to the floor when you open the bleeder they need to hold it there until you tighten the bleeder you will half to keep doing this until you feel you have gotten all the air out of that line than go to the next caliper/wheel cylinder make sure you don't let the brake fluid reservoir go empty or you will half to start over. when you are done your brake pedal should be tight if it feels spongy you probably still have air in one of the lines. the bleeder should look something like this.25301046-scwq1xk2qxq0hxt3anvu5zxk-2-0.jpg

After bleeding brakes still have spongy brakes


you still have some air in the lines. go back thru the bleed process again if that doesn't work, get to a power brake bleeder.(amazon about$70) that is a system that puts pressure on top of mc to push fluid thru the system as you open bleed screws. did you know you can adjust brakes by holding down lock button and pumping emergency brake handle. good luck

Is the master cylinder good? a bad master can cause this also did you bleed the master first before bleeding at the wheel and also make sure the bleeder screw is clean, if the hose is good then theres only a few things, a bad master or a master that wasnt bleed, try bleeding the master first then try rebleeding the brakes.

How do i bleed the brakes on a 1999 Pontiac Grand Am?


Bleeding the Brake System
When any part of the hydraulic system has been disconnected for repair or
replacement, air may get into the lines and cause spongy pedal action (because
air can be compressed and brake fluid cannot). To correct this condition, it is
necessary to bleed the hydraulic system so to be sure all air is purged.

When bleeding the brake system, bleed one brake cylinder at a time, beginning
at the cylinder with the longest hydraulic line (farthest from the master
cylinder) first. ALWAYS Keep the master cylinder reservoir filled with brake
fluid during the bleeding operation. Never use brake fluid that has been drained
from the hydraulic system, no matter how clean it is.

The primary and secondary hydraulic brake systems are separate and are bled
independently. During the bleeding operation, do not allow the reservoir to run
dry. Keep the master cylinder reservoir filled with brake fluid.


  1. Clean all dirt from around the master cylinder fill cap, remove the cap and
    fill the master cylinder with brake fluid until the level is within 1/4 I n.
    (6mm) of the top edge of the reservoir.
  2. Clean the bleeder screws at all 4 wheels. The bleeder screws are located on
    the top of the brake calipers.
  3. Attach a length of rubber hose over the bleeder screw and place the other
    end of the hose in a glass jar, submerged in brake fluid.
  4. Starting at the right rear proceed in this order left front, left rear and
    right front.
  5. Open the bleeder screw 1/2 - 3/4 turn. Have an assistant slowly depress the
    brake pedal.
  6. Close the bleeder screw and tell your assistant to allow the brake pedal to
    return slowly. Continue this process to purge all air from the system.
  7. When bubbles cease to appear at the end of the bleeder hose, close the
    bleeder screw and remove the hose.
  8. Check the master cylinder fluid level and add fluid accordingly. Do this
    after bleeding each wheel.
  9. Fill the master cylinder reservoir to the proper level.

when bleeding brakes always use a hose (windsheild wiper hose works great) put one end of the hose on the bleeder cap and the other end in a bottle of brake fuild so no air get's back into the line.

Brakes are spongy,light keeps coming on,even after bleeding them


If there are no leaks from wheel cylinders, calipers and lines, likely there is a bypass condition in the master cylinder. If so, replace it.

93 chevy lumina the brake lines aren't getting fluid


Open the bleeder screws on your brake, and stick a gas line hose on the bleeder screw. Put the other end in a clear bottle of brake fluid, and pump the brake till all the air bubbles quit coming out. Then tighten the bleeder. If no bubbles come, you may have a faulty master cylinder.

Bleeding brakes


No need to run the engine. Start the bleed procedure from the caliper farthest from the master cylinder, and work toward it. This means bleed the passenger rear first, then the driver rear, then passenger front, then driver front. Don't stop bleeding any caliper until you get three or so consecutive streams of air-free fluid through the bleeder. Monitor the level of fluid in the cylinder, and be sure the cap is on while bleeding - only open it to add additional fluid as needed.
