First, check the master cylinder and make sure there's fluid in it. If not, top off the master cylinder and bleed the brakes again. You must bleed the brakes slowly because the hole that feeds the brake fluid into the plunger of the master cylinder is very small. Depress the pedal, open the bleeder valve, close the bleeder valve, let off on the brake pedal and wait a minute or two before doing the process again. Give the plunger time to refill with brake fluid and do not allow the master cylinder to go empty while bleeding is in process.

Now, in the very bottom of the master cylinder, there are two holes. One is pretty big but the other one is quite small. The large hole is a "bleed off" hole that allows a certain amount of brake fluid to "bleed off as you depress the pedal". If this were not there, you would be unable to feel the brake pedal move at all when you stepped on it. The small hole is the one we're concerned with you you can't get a pedal to build up. It could be stopped up. The hole is somewhere around 0.020" in diameter. Sometimes a bit of trash gets into the hole and prevents brake fluid from filling the plunger. Clean the hole out with a small drill bit or piece of wire. Do not enlarge the hole.

Good Luck

Had both front wheel calipers off and did linings. Now I have no brake pedal to speak of. Tried bleeding old fashioned two man way and did not work. Car is a 1998 buick regal LS

Do you have an electronic brake pressure pump for brake assist that you may want to make sure works properly. When turning ignition on, you should hear the motor run, also when you press the brake pedal.

No breaks after bleeding them

Did you bleed the brakes properly? One person pumps the brake pedal then holds it down while another person loosens and then retightens the bleeder valve. This way no air can enter the brake line which can dramatically affect braking pressure and thus have no brakes at all.

You never replace only one caliper

You do both sides

Bleeders are mounted to top of caliper

Have a helper in drivers seat to slowly

Whats the proper way to bleed the breaks

Bleeding the Brake System (ABS) Auto Bleed Procedure NOTE: Perform a manual bleeding procedure. If the brake pedal height and firmness results are not achieved, perform the auto bleed procedure below.
  1. Raise and support the vehicle.
  2. Remove the tire and wheel assemblies.
  3. Inspect the battery state of charge.
  4. Install a scan tool.
  5. Turn ON the ignition, with the engine OFF.
  6. With the scan tool, establish communications with the ABS/TCS system. Select Special Functions from the ABS/TCS menu. Select Automated Bleed from the Special Functions menu.
  7. Bleed the base brake system.
  8. Follow the scan tool directions until the desired brake pedal height is achieved.
  9. If the bleed procedure is aborted, a malfunction exists. Perform the following steps before resuming the bleed procedure:
  10. If a DTC is detected, refer to Diagnostic Trouble Code (DTC) List and diagnose the appropriate DTC.
  11. If the brake pedal feels spongy, perform the conventional brake bleed procedure again.
  12. When the desired pedal height is achieved, press the brake pedal in order to inspect for firmness.
  13. Remove the scan tool.
  14. Install the tire and wheel assemblies.
  15. Inspect the brake fluid level.
  16. Road test the vehicle while inspecting that the pedal remains high and firm.
Bleeding ABS Automated Bleed Procedure NOTE: In most circumstances a base brake bleed is all that is required for most component replacements (such as wheel cylinders, calipers, brake tubes, and master cylinder) except for brake pressure modulator valve (BPMV) replacement.
The following automated antilock brake system (ABS) bleed procedure is required when one of the following occur:
  • Manual bleeding at the wheel cylinders does not achieve the desired pedal height or feel.
  • Replacement of the BPMV
  • Extreme loss of brake fluid has occurred.
  • Air ingestion is suspected.
NOTE: If none of the above conditions apply, use standard bleed procedures.
The auto bleed procedure is used on BOSH 5.3 equipped vehicles. This procedure uses a scan tool to cycle the system solenoid valves and run the pump in order to purge the air from the secondary circuits. These secondary circuits are normally closed off, and are only opened during system initialization at vehicle start up and during ABS operation. The automated bleed procedure opens these secondary circuits and allows any air trapped inside the BPMV to flow out toward the wheel cylinders or calipers where it can be purged out of the system.
Preliminary Inspection
  1. Inspect the battery for a full charge.
  2. Repair the battery and charging system as necessary.
  3. Connect a scan tool to the data link connector (DLC) and select the current and history DTCs.
  4. Repair any DTCs prior to performing the ABS bleed procedure.
  5. Inspect for visual damage and leaks and repair as needed.
Preliminary Setup
  1. Before servicing the vehicle refer to the precautions at the beginning of this section.
  2. Raise and support the vehicle.
  3. Turn the ignition switch to the OFF position.
  4. Remove all 4 tires (if necessary)
  5. Connect the pressure bleeding tool.
  6. Turn the ignition switch to RUN position with the engine off.
  7. Connect a scan tool and establish communications with the ABS system.
  8. Pressurize the bleeding tool to 30-35 psi (206-241 kPa).
Automated Bleed Procedure
NOTE: The Auto Bleed Procedure may be terminated at any time during the process by pressing the EXIT button. No further Scan Tool prompts pertaining to the Auto Bleed procedure will be given.
After exiting the bleed procedure, relieve bleed pressure and disconnect bleed equipment per manufacturers instructions. Failure to properly relieve pressure may result in spilled brake fluid causing damage to components and painted surfaces.
  1. With the pressure bleeding tool set to 30-35 psi (206-241 kPa) and all bleeder screws in closed position, select Automated Bleed Procedure on the scan tool and follow the instructions.
  2. The first part of the automated bleed procedure will cycle the pump and front release valves for one minute.
  3. After the cycling has stopped the scan tool will enter a "cool down" mode and display a 3 minute timer. NOTE: The auto bleed will not continue until this timer expired, and cannot be overridden.
  4. During the next step, the scan tool will request the technician to open one of the bleeder screws. The scan tool will then cycle the respective release valve and pump motor for 1 minute.
  5. The scan tool will repeat step 3 for the remaining bleeder screws.
  6. With the bleeder tool still attached to the vehicle and maintaining 30-35 psi (206-241 kPa), the scan tool will instruct the technician to independently open each bleeder screw for approximately 20 seconds. This should allow any remaining air to be purged from the brake lines.
  7. When the automated bleed procedure is completed the scan tool will display the appropriate message.
  8. Install all 4 tires, if necessary.
  9. Remove the pressure from the pressure bleeding tool
  10. Disconnect the tool from the vehicle.
  11. Depress the brake pedal to gauge pedal height and feel.
  12. Repeat the procedure until the pedal is acceptable.
  13. Remove the scan tool from the DLC connector.
  14. Safely lower the vehicle.
  15. Inspect the brake fluid level in master cylinder.
  16. Road test the vehicle while ensuring the brake pedal remains high and firm.
  17. If the vehicle is equipped with a traction control system (TCS), the scan tool will cycle both the ABS and TCS solenoids valves. This bleed procedure is the same as above.

My clutch is not angaging need to see how can i bleed

Hydraulic Clutch System BLEEDING The clutch system can be bled using a pressure bleeder. Follow the instructions that come with the pressure bleeder for the proper pressure bleeding procedure. The maximum line pressure while pressure bleeding must not exceed 36 psi (248 kPa). NOTE: To bleed a clutch manually requires the assistance of a second person, a section of hose that is compatible with brake fluid (preferably clear) and fits the slave cylinder bleed screw snugly and a container to catch the fluid that is bled through the system. As brake hydraulic fluid easily absorbs moisture, always use fresh fluid when bleeding a hydraulic system.
  1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
  2. To bleed the system perform the following:
    1. Top off the hydraulic fluid reservoir using a fluid that meets the standards of the vehicle's hydraulic system.
    2. Open the clutch slave cylinder bleed screw and press the clutch pedal to the floor and hold the pedal down.
    3. Close the clutch slave cylinder bleed screw.
    4. Release the clutch pedal.
    5. Check the hydraulic fluid level and top off as necessary.
  3. Repeat the above steps until the discharged fluid is clean and no air bubbles appear during the bleeding process.

Rear brake not holding pressure , pedal goes to the floor

Is your rear rotor warped? if the rotor is warped it will push the pads out causing you to have to pump them to stop.Remember the dot 5 is aeroscopic. if you shake or drop the bottle of fluid, you cannot use it for at least 24 hours. it will continue to create air in itself for that long. so even if you bleed the system correctly it will continue to introduce air into the system.

No brakes

Hi Robert!

When bleeding the fronts and the pedal does not go down all the way, stand on the pedal HARD and see if it won't go down then...

The proper sequence is to bleed fronts FIRST... if you had done this, you probably could have avoided this problem... but no worry, it is just a nuisance!

If you still have a problem after trying this, you might have a master cylinder problem... the seals to the fronts might be leaking, not able to build pressure...

So try this and let me know how it goes, and DON't FORGET: Your rating is my ONLY compensation for helping you!
