There's still air in the lines, just open the bleeder screws all of them and gravity bleed them , take the resovoir cap off and make sure you keep fluid in it . This may take some time but you will be happy when done. If you bleed them with a friend do one at a time pump the pedal, keep pressure on pedal and open the bleeder screw. when pedal goes to the floor repeat the process until its only fluid that exits the bleeder. Repeat this for the rest of the bleeders.

Brake pressure issue


Wow, that's different. There are only a few things left to try. To keep from buying unneeded parts first try bleeding this way one more time.

Do the longest brakeline first, then next longest, until you work your way to the shortest line. Then try it.

Now for a difference when starting the engine, your Brake booster is working. You should have a Reserve of Vacuum in the booster for at least one pedal depression. If you don't, the Booster valve or Booster Bladder is bad.

The Booster valve is relatively cheap. Test the booster bladder; you do not want to use a chemical. With the engine running, some people will use a torch propane tank with a rubber hose on it to direct propane around the Brake booster. The propane will cause the engine RPM to change indicating a bad bladder. Propane is safe in small amounts and was used to set air/mix in the early days of Pollution control.

The Master cylinder could have pulled in sediment when the old parts were removed from the system. Now it is hanging up.

For bleeding brakes there are different methods. I prefer to draw fluid with a hand Vacuum pump like a Mighty Vac. The advantages are it is less messy and far more controllable. Pumping a defective Master cylinder may not work for you. Power bleeding with a Canister and Master cylinder cap adapter will be better than relying on the Master cylinder alone. Gravity bleeding works, but may not work with a bad Master cylinder leaking more fluid in one chamber than the other.

Check for hose twists in the rubber lines you replaced. The ridges on the hoses should be parallel when you hang the caliper.

Please rate my info and let me know the final solution.

Experienceing loss of power to brakes


1. What is the Brake Fluid Level?
2. Are you losing any Brake fluid at all? Are there any puddles or noticeable wetness on the ground or on the tires/wheels? With vehicle parked, the reservoir filled (overfilled), and engine running: pump the brakes and check on the ground and back sides (inside portions) of the wheels. Look for any brake fluid leaks.
3. Leaks from Calipers usually means a leak from the caliper piston. The rubber seals will be wet.
Leaks from Drums usually means a leak from the wheel cylinder.
4. In any case of leaks from the wheels - replace the calliper OR wheel cylinder.
For caliper leaks: change the brake pads, and clean the rotors with brake cleaner.
For drum leaks: clean the drum and brake hardware with brake cleaner, and replace the shoes.
5. If no leak is detected from the wheel area's: check under the Master Cylinder for wetness indicating a possible leak.
6. If no leak can be found: you MAY have a rear seal leak in the Master Cylinder which is pumping Brake Fluid into the Brake Booster (that large disk looking thing attached to the fire wall, attached to the Master Cylinder in front).
a. Use a large drip/catch pan under the Van in the area on the Master Cylinder.
b. Disconnect the brake lines from the Master Cylinder using a flair wrench.
c. Remove the two nuts (12 or 13mm?) attaching the Master Cylinder to the Brake Booster. If you have been using a lot of fluid, and have found no leaks, here is a good possibilty that all that brake fluid has collected in the Booster; so when you detach the Master Cylinder from the Brake Booster, all that fluid will come rushing out!
7. If there is Brake Fluid inside the Brake Booster: there is no cleaning that out. Brake Fluid is very caustic to the seals inside the Booster and should be replaced.
8. Of course the Master Cylinder will also have to be replaced.
9. After replacing the Master Cylinder/Brake Booster - make sure you get all that spilled brake fluid off the engine compartment area parts! I use a brake cleaner, then mild soap and then water to rinse. Clean any Brake Fluid off Paint imediatley as it will quickly dissolves finishes and paint.
10. If no leak is detected and the Booster is clear, there may be problems with the Booster One-Way Valve. This is attached to the outside of the Booster and has a hose from an "advance" connected to it. This maybe malfunctioning where you are losing power. Replace this first before deciding to replace the whole booster (in cases of NON-LEAKS ONLY). If that did not work, there may be inner seals inside the Booster that have failed. That means a new Booster.
11. In any of the above cases: Make sure you bleed the Master Cylinder correctly and bleed the brakes (at each affected wheel) correctly. Any air in the brake lines will decrease your braking proficiency or could result in brake failure.

Let me know if this helped or if you have any additional information or questions. Feel free to contact me at FixYa.com!

BRAKE BOOSTER?


A bad brake booster will result in a hard brake pedal, stiff and more effort required to stop the truck. Here are my questions to you, first, you said you replaced the master cylinder, did you bench bleed it before you installed it? If not, there IS still air in it, regardless of how much you bleed the brakes at the wheels. Second, when you bled the brakes, after changing the calipers and master cyl., did you also bleed the proportioning valve? Sometimes air can get trapped in the valve, and its almost impossible to get it out bleeding just the wheels. And lastly, when the brake light comes on, does the abs light also come on with it? Air can also get trapped in the abs control module too.
