Get a friend. Pump the pedal and hold it down, then open up the valve until fluid squirts out, close the valve, Then release the pedal, do it a few times moving around all 4 corners of the vehicle. There is a valve on each caliper and each wheel cylinder. I believe they are 7mm if memory serves me right.

Do not release the pedal until the valve is closed or you will suck more air into the system.

We're just a bunch of dummies here too, but I hope you can trust us anyway.

Start with the furthest wheel from the master cylinder.

RF
LF

By the way, did you actually call the person a dummy or are you just saying that here?

^^ proper sequence.

If you have a friend helping you....after doing the 2 rear wheels, check the master cylinder to ensure there is enough fluid in there to bleed the fronts without the mastercylinder going dry. ONce done top off as needed

Hydraulic Brake System Bleeding (Manual)

Warning: Refer to Brake Fluid Irritant Warning in the Preface section.

Caution: Refer to Brake Fluid Effects on Paint and Electrical Components Caution in the Preface section.

1. Place a clean shop cloth beneath the brake master cylinder to prevent brake fluid spills.

2. With the ignition OFF and the brakes cool, apply the brakes 3-5 times, or until the brake pedal effort increases significantly, in order to deplete the brake booster power reserve.

3. If you have performed a brake master cylinder bench bleeding on this vehicle, or if you disconnected the brake pipes from the master cylinder, you must perform the following steps:

3.1. Ensure that the brake master cylinder reservoir is full to the maximum-fill level. If necessary add GM approved brake fluid from a clean, sealed brake fluid container.

If removal of the reservoir cap and diaphragm is necessary, clean the outside of the reservoir on and around the cap prior to removal.

3.2. With the rear brake pipe installed securely to the master cylinder, loosen and separate the front brake pipe from the front port of the brake master cylinder.

3.3. Allow a small amount of brake fluid to gravity bleed from the open port of the master cylinder.

3.4. Reconnect the brake pipe to the master cylinder port and tighten securely.

3.5. Have an assistant slowly depress the brake pedal fully and maintain steady pressure on the pedal.

3.6. Loosen the same brake pipe to purge air from the open port of the master cylinder.

3.7. Tighten the brake pipe, then have the assistant slowly release the brake pedal.

3.8. Wait 15 seconds, then repeat steps 3.3-3.7 until all air is purged from the same port of the master cylinder.

3.9. With the front brake pipe installed securely to the master cylinder, after all air has been purged from the front port of the master cylinder, loosen and separate the rear brake pipe from the master cylinder, then repeat steps 3.3-3.8.

3.10. After completing the final master cylinder port bleeding procedure, ensure that both of the brake pipe-to-master cylinder fittings are properly tightened.


4. Fill the brake master cylinder reservoir with GM approved brake fluid from a clean, sealed brake fluid container. Refer to Master Cylinder Reservoir Filling. Ensure that the brake master cylinder reservoir remains at least half-full during this bleeding procedure. Add fluid as needed to maintain the proper level.

Clean the outside of the reservoir on and around the reservoir cap prior to removing the cap and diaphragm.

5. Install a proper box-end wrench onto the RIGHT REAR wheel hydraulic circuit bleeder valve.

6. Install a transparent hose over the end of the bleeder valve.

7. Submerge the open end of the transparent hose into a transparent container partially filled with GM approved brake fluid from a clean, sealed brake fluid container. Refer to Fluid and Lubricant Recommendations.

8. Have an assistant slowly depress the brake pedal fully and maintain steady pressure on the pedal.

9. Loosen the bleeder valve to purge air from the wheel hydraulic circuit.

10. Tighten the bleeder valve, then have the assistant slowly release the brake pedal.

11. Wait 15 seconds, then repeat steps 8-10 until all air is purged from the same wheel hydraulic circuit.

12. With the right rear wheel hydraulic circuit bleeder valve tightened securely, after all air has been purged from the right rear hydraulic circuit install a proper box-end wrench onto the LEFT REAR wheel hydraulic circuit bleeder valve.

13. Install a transparent hose over the end of the bleeder valve, then repeat steps 7-11.

14. With the left rear wheel hydraulic circuit bleeder valve tightened securely, after all air purged from the left rear hydraulic circuit, install a proper box-end wrench onto the RIGHT FRONT wheel hydraulic circuit bleeder valve.

15. Install a transparent hose over the end of the bleeder valve, then repeat steps 7-11.

16. With the right front wheel hydraulic circuit bleeder valve tightened securely, after all air has been purged from the right front hydraulic circuit, install a proper box-end wrench onto the LEFT FRONT wheel hydraulic circuit bleeder valve.

17. Install a transparent hose over the end of the bleeder valve, then repeat steps 7-11.

18. After completing the final wheel hydraulic circuit bleeding procedure, ensure that each of the 4 wheel hydraulic circuit bleeder valves are properly tightened.

19. Fill the brake master cylinder reservoir to the maximum-fill level with GM approved brake fluid from a clean, sealed brake fluid container. Refer to Master Cylinder Reservoir Filling.

20. Slowly depress and release the brake pedal. Observe the feel of the brake pedal.

21. If the brake pedal feels spongy, repeat the bleeding procedure again. If the brake pedal still feels spongy after repeating the bleeding procedure, perform the following steps:

21.1. Inspect the brake system for external leaks. Refer to Brake System External Leak Inspection.

21.2. Pressure bleed the hydraulic brake system in order to purge any air that may still be trapped in the system.

22. Turn the ignition key ON, with the engine OFF. Check to see if the brake system warning lamp remains illuminated.

Note: If the brake system warning lamp remains illuminated, DO NOT allow the vehicle to be driven until it is diagnosed and repaired.

23. If the brake system warning lamp remains illuminated, refer to Symptoms - Hydraulic Brakes.

The Motive Power Bleeder is a nice tool to have if you're by yourself.

Power Bleeder Instructions

Directions for using the POWER BLEEDER:

WARNING: Hydraulic fluid is hazardous. Read and follow fluid manufacturer's warnings. Hydraulic fluid is corrosive and may damage automobile paint or other surfaces. If fluid spills, flush with water immediately. Always wear safety goggles when working with hydraulic fluid.

DIRECTIONS: Use your Power Bleeder only as directed. Read these directions completely before starting. The Power Bleeder0 is intended for use only by individuals experienced with bleeding and servicing hydraulic systems. If you are unsure about your ability or experience, consult a trained professional. Always follow vehicle manufacturers' directions when bleeding hydraulic systems.

1. Ensure that Power Bleeder is clean and free of debris, old hydraulic fluid, or any cleaners or solvents.

2. Remove hydraulic fluid reservoir cap from vehicle. If old fluid is excessively dirty, siphon it off and refill reservoir with fresh fluid. Do not pump excessively dirty fluid through hydraulic system.

3. Firmly attach Power Bleeder cap to the fluid reservoir, ensuring that gasket seats properly and is not worn or cracked.

4. Tighten pump cap onto empty Power Bleeder and pressurize to recommended operating pressure as per repair manual psi. Check for leaks at fluid reservoir and at Power Bleeder fluid hose connections. If reservoir cap or hose connections are leaking, release accumulated pressure in Power Bleeder by gently unscrewing the pump cap. Never remove reservoir cap before depressurizing Power Bleeder tank. Reattach Power Bleeder reservoir cap or tighten hose connections and once again pump tank to 10 psi and check for leaks.

5. If no leaks are found, unscrew pump cap and add up to 2 quarts of new hydraulic fluid from a sealed container. Use only the type of hydraulic fluid recommended for your vehicle.

6. Tighten pump cap. Pressurize Power Bleeder to level recommended in vehicle service manual. Do not exceed 20 psi. Higher pressures may damage your vehicle's hydraulic system and could result in serious injury.

7. Determine proper brake bleeding sequence from your vehicle service manual. Attach bleed tube to bleed valve at the first cylinder to be bled; place open end in a suitable fluid receptacle. Open bleed valve; bleed until fluid runs clear and free of bubbles. Tighten bleed valve to the torque specified in your service manual.

8. Repeat on each bleed valve. Pump additional pressure into Power Bleeder if necessary.

9. If fluid remains in the Power Bleeder tank when through: tip the tank away from fluid pick-up tube and open bleed valve closest to the master cylinder. Allow air to flow into fluid reservoir until fluid level falls just to the maximum fill level on your reservoir. Close the bleed valve and tighten to specified torque.

10. When complete, release pressure by slowly loosening pump cap. Remove the cap from fluid reservoir, taking care to avoid spilling any fluid that remains in the tube.

11. Replace fluid reservoir cap on your vehicle, checking that fluid level is at the maximum level indicated on reservoir.

12. Before driving car, carefully check for leaks and test for proper brake operation.

13. Never store hydraulic fluid in Power Bleeder. Always dispose of excess fluid properly. Do not clean your Power Bleeder with brake parts cleaners or other solvents not intended for use with plastic components. Lubrication of the Power Bleeder pump mechanism should not normally be necessary. Should lubrication be required, apply a small amount of brake fluid compatible grease to the Power Bleeder pump shaft. Never lubricate with petroleum-based oils.

14. Cleaning and Maintaining the Power Bleeder - To clean the POWER BLEEDER after use pour denatured alcohol into the tank and into the tube. Dispose of the dirty alcohol. Allow the unit to air dry. Store in a cool, dry, dark area with the hose wrapped loosely around the unit without any kinks in the hose. DO NOT USE BRAKE CLEANER ON ANY PART OF THE UNIT. If denatured alcohol can not be found a mild dish washing detergent may be used, however insure all soap is rinsed out prior to air drying unit and that unit is completely dry prior to next use. We highly recommend replacing the hose every 3-4 years or if inspection shows any damage to the hose.

I have the same power bleeder as Rich and I love it. To throw a little something in the mix. There has been much discussion by mechanics about the proper way to manually bleed brakes. Here is another way to do it. Anyone that has ever worked on forklifts and simular equipment know this. The bleeding sequence is correct...RR, LR, RF, & LF. Now to bleeding. 2 persons needed. With one person seated in the drivers seat, one under the vehicle. Open the bleeder valve at the wheel then have the other person depress the pedal to the floor and hold it. Tighten the bleeder screw and have the person release the pedal. Continue this procedure until you only get straight brake fluid from the wheel. In other words no more air of foam. Then move to the next wheel. This way you never pull air back and forth in the system it is always moving to the bleeder and out of the system.

I'm sure some will not agree with this but it works well. Also I stated up front that it has been a discussion with mechanics for years. However the best way is with a power bleeder that way you can do the job unassisted. The suggestion about brake adjustment is a good point maybe you may need an adjustment. Bleed first and then check the adjustment.
