would you try and open an 18yr old rear bleed screw?

[S-west]

Where I live I've had bleeders rust so bad you can't even tell its a bleeder and it snaps right off. And that is on my 2001. The salt kills everything up here

Just save yourself the time/hassle and just replace the wheel cylinder and the bleeders. The seals in the wheel cylinders are 18 years old also. When one blows you lose all your brakes. Why they went to a single chamber master cylinder I will never know?!?!

Most of the suggestions posted here are very good ones. The heat and cool idea is very good. The hammer shock treatment is another good idea. The thought that the threads are covered in brake fluid is not true. At the bottom of the fitting there is a taper that fits into another taper closeing off the port that allows fluid to flush out of the fitting. If your a non believer just remove the fitting from the cylinder and have a look see. These are an interesting device too.

if you have never snapped a bleeder screw you havent been working on vehicles long enough...

wheel cylinders are cheap enough id just replace them

Or you live in sunny SoCal where rust and corrosion are just these things you've heard of...........

Remember, all of the threads you don't see are exposed to brake fluid which has similar properties to our penetrating fluids that we use except it also eats paint[/QUOTE]

draw a pic,,of how the bleeder screw,,fits into its hole........

your going to find that a truck left sitting like this,with low miles is just going to have blown out wheel cylinders anyway once you start running the truck regularly.

mmmm, ok....................

 

[sassyrel]

in no uncertain term is there any brake fluid present there. The taper on the tip of the bleed screw fits into a similar taper in wheel cylinder. While bleeding there may indeed be brake fluid but being that brake fluid hydroscopic in that it takes moisture in like a sponge, any remaining after a bleed will just rust once it gets any moisture in it.....

I don't know how you figured the threads are exposed to fluid except for a short time while bleeding!

straight riot,,straight...

X2!

I don't know about on Fords, but every M-B owner's manual I've ever looked at gives an interval for changing/flushing the fluid in the brake system...you're supposed to do it annually. I don't follow that religiously, but I try to change it fairly regularly. The rationale I've heard behind it is that, even in a brake system, the fluid will still attract water, which in turn can either boil on a hard brake application or can rust out the brake system internals. I ended up replacing the complete hydraulic brake system on an '83 300D because of this (and this was before the car ever set tire in Pacifica ) ...
