If there is more than one caliper on the rear wheels make sure you bleed both cylinders.

Somewher i that system has an air trap, if you can push the cylinder like that.
I guess you have to check all four ans ee if all of them are like that. if so, you have to redo the master. if just 1 or 2 cylinder, then you have bleed them again.
I can think anything else, I will post it, if I can up some thing else.

I have a 1980 datsun 1200 ldv have replaced the master cylinder Bled all 4 wheels.Pedal stays low +_ 10 mm from floorboard Do not find air in the system had adjusted all 4 wheels brakes thanks


Did you properly bench bleed the master cylinder itself before installing? It must be bled or there will be air trapped inside the master cylinder itself that no amount of wheel bleeding will remove.

My first guess would be the power brake booster is leaking vac.

The inside, large pin, that pushes out to the hydroboost, may have fallen out when you took off the booster. Also the pin from the booster to the master cylinder may have been stuck inside the hydroboost that you took out. Pull the master cylinder off. You will see that the large shaft/pin is missing. Good luck.

2001 Silverado 2500 HD Why Rear brakes don't work after I installed new hydro-boost power booster, master cylinder, calipers, and pads. I bled master cylinder before installing, and brakes beginn


Hello Patricia,

Have you checked the master brake cylinder reservoir for brake fluid loss?

I don't suspect the master cylinder as you have replaced it... but am more suspect of a leaking brake line or fitting which should have
been discovered when you had the system bled.

The only time I ever had a rear brake problem with a 2500 series Chevrolet was due to seized rear brake caliper guide pins...as your calipers are also new that is not your problem.

If your brake pedal feels spongy and travels to the floor board you have air in the system, a brake fluid leak or a failure in the power steering system, such as a broken hose, broken power steering pump drive belt, or failed pump, would result in a loss of pressure to both the hydro-boost and steering.

We have replaced everything to do with the brakes, vacuum booster, master cylinder, etc. We have done a complete bleed and still have no pedal when we start the car. Any ideas


Hi Friend:

#1) Check and make sure your Power brake boosters Hose is not Cracked or just not a tight fit going to Intake.

#2) Since you Have Rear Drum Brakes You might have left to much Brake to Drum Clearance==Ajust rear Brakes out to Just give you good clearance to slide Drum Over Brakes.

#3) Check all your Brake Lines for Possible leaks.

#4) CHECK to make sure your Accuating Rod from your Brake Pedal to your Power Brake Booster is in the Rear of Boosters Piston that whenb you apply brake its Acctuating the Power Booster.

#5) Also did you bench bled your Master before instaling? If not you'll have to bled your master clylinder 1st, and then Start at farest wheel from master cylinder and work your way to the brakes on front Drivers side.

#6) only other thing that comes to mind is your Anti Brake Module.

Hope this has helped you ,PLEASE let me know by Voting For the Soultions i've Given You.

Thank and Good Luck d_hubbs

Just replaced rotors, calipers, caliper brackets, and pads. Bled all four wheels, starting with the farthest away from the master cylinder working my way to the closest. Brake pedal feels firm when car...


Bleed with the car running and make sure all the air is out. Now make sure there is no leak and the pad contact are adjusted without much gap so that the calipers hold on. make sure the servo assist is correct, if so and the master cylinder was set right , it must work. Please recheck all your work once again to trim up.

New master cylinder and booster. Brakes stop good


Well if you have bled it correctly starting at the farthest out(PS Side Rear) and working to the closest(DR Side Front) and you make sure to close the bleeder valve before letting up and repumping the peddel,then I would say that the seals in your new master cylinder may be bad.When you bled the second or third time if there was no air then I would say you have a bad master cylinder.If there was air then you have another problem.Well hope this helps and good luck.

Install new brake pads and rotors all 4 wheels. Replaced front 2 calipers. Bled brakes. New clean fluid coming out. pedal is still soft and goes to floor. 200 Seebring.


Are you losing any Brake Fluid? Is it visible anywhere at the four wheels? Is it visible anywhere else?
The Master Cylinder may be defective. When you bled the Brakes did you maintain proper Brake Fluid Level in the Master Cylinder? If you didn't: and air entered into the Master Cylinder there maybe air within in the system in the Master Cylinder. You can bleed the Master Cylinder by removing the brake lines, adding more fluid, pumping the brakes, bleeding the air out of the system.
Are you losing Brake Fluid and can't find a noticeable leak? Then there is a good posibility that the rear seal in the Master Cylinder is leaking and the Fluid is going into the Brake Booster - which is the large wheel shaped drum located on the fire wall. In this case both the Brake Booster and the Master Cylinder will have to be removed and replaced. The Booster contains seals that Brake Fluid is very caustic to and will ruin these seals- causing future failures.
If no Brake Fluid is lost, no leak found: Check the Brake Booster Vacuum Advance. This should be connected to the outside of the Booster, attached to a hose, with the hose going to the engine. Check to see if this is working properly. Replace if needed.

Bleed right rear,left rear, right front, left front in that order to be sure of good bleed but the brake booster makes it easy to push pedal. Make sure of no leaks from master cylinder. Otherwise brake hoses being soft will also hurt baking quickly.
