hydro boost leaking ?

[84cucv1ton]

my fathers m1031 pedal when to the floor this morning. pulled it into the garage. looked all over the truck. all i could find was where the rod goes through the firewall, there is drops of fluid coming down. so the hydro boost need to be replaced?

second question, are all the hydro boots the same? i have some from m1009s but none m1008s. same unit??

thanks

you sure the master is not shot? if the booster was shot you would not be able to push the to the floor.. like not having power brakes.

i thought it would be the booster since it was leaking in the truck

Well one way to check is find out which system is low, power steering fluid or brake fluid. Also you should be able to smell the difference between the two fluids. I think that you will find that it's the master and the fluid is pushing through the booster or running all over the outside of the booster and weeping through the firewall. Let us know what you find...

Similar problem here.

My PS fluid is leaking at the Brake Booster. I am hoping that the Lucas Stop Leak (once added) will correct this. My first symptoms were a pulating brake pedal when stopping, and slight PS pump whine. Fluid added, all was well again. I have not been able to located the exact source of the leak.

Instead of me typing it out here is a video that I googled.

The above video dose not show how you can put some plugs the threaded ports where the break lines go and use some vacuum lines to loop them back into the reservoir so fluid can come out the reservoir ports in the master as we ports to the lines.

Here is link to a pic that someone did with scrap break lines but you will get the point. http://www.stovebolt.com/techtips/master_cylinder/bleed.jpg
