Does anyone else have a sqeaky mastercylinder/brakebooster? Everytime I press the brakes while going slow I hear a sqeaking noise that I thought was coming from the linkage in the brake system but after spraying lube on everything and further troubleshooting I determined that it's actually coming from inside the mastercylinder/brakebooster assembly. I bleed my brakes and the noise when to about half of what it was but its still there. I use to not have any noise at all. I checked a friend of mine's truck and his is doing the same thing and it also is driving him crazy. Is anyone else in the same boat and did you fix it?

Yep, I've got the squeak also. Irritating noise but the brakes work just fine.

I do also. I just flushed my power steering system with redline high temp atf and the pedal feels much better and a lot of the noise but not quite all of it has gone away!

Tired some Limited Slip Fluid in there....."Did Nothing"

Hoping you can find out what's going on, cuz I don't know.. /ubbthreads/images/graemlins/phoney.gif

Vapstroke, How did you flush you p/s system? I need to do the same and would like a quick "how to" if you dont mind.

Thanks

Jack up and support the front end so the wheels dont touch the ground. Then disconnect the return hose from the power steering pump. This is the hose that connects with a clamp to the top of the pump resevoir. I then capped off the fitting on the resevoir where the line was attached. Then get a adapter that will allow you to connect a section of clear hose to the hose you disconnected and run the end of the clear hose into a old bucket. Take the cap off of the resevoir and put a funnel into it. Have someone get into the truck and start it up. Have them turn the wheel slowly lock to lock while pumping the brake pedal as you slowly pour the new fluid in the funnel. You should notice a color change of the fluid in the clear tubing when you have gotten all the old stuff out. I ran about six qts through mine to be sure and get all the old stuff out.

Thanks! That sounds easy enough. Now I just need to convince my 2 and 4 year old kits that I need the time to do it, thats going to be the hard part.
