I will definately let you know - unfortunately I am having some problems.

As my car has ABS, the Hanes manual says that "special equipment" is needed to bleed the system after the master cylinder is replaced. i have posted a thread asking fo assistance in determining what this equipment is, but no one has responded.
Since I don't have a spare vehicle, I cannot risk undertaking this project unless I know that i have everything i need before I start.

Any ideas as to what equipment i need???

It's probably a brake flushing tool that forces brake fluid into the braking system in order to push air through the abs unit and out the wheel cylinders. If air gets trapped in the ABS unit, it likely won't work, and will probably kick on the ABS fault light.

So, I have searched the focusfanatics forums very thoroughly, and I feel pretty confident even without inspection that the problem lies within the master cylinder.

Focusfanatic Grumpy said it best, in my opinion:

"If you can get the pedal hard by letting the pedal up and then quickly applying the brakes again, it ain't air in the system, but assuming there are no external fluid leaks, you've probably got the master cylinder bypassing fluid (fluid leaks past a piston seal). Usually will be noticed when applying the brakes for a relatively long time, and the pedal will slowly drop towards the floor. It IS NOT normal. Get to a dealer.......the warranty should cover it. It is not normal wear and tear on the brakes."

However I would like to avoid the dealer if possible. Does anybody have any experience with replacing the master cylinder on an '05 Focus? Is a pressure bleeder or specialty dealer tool really necessary?

I actually don't mind spending the money on a pressure bleeder since I'll probably come out ahead of a dealer repair bill anyways, I'm just wondering.

On my 2000 with ABS the instructions are to use special Ford test equipment when bleeding the system if air has entered the ABS unit. Since that was not the case, I only had to be sure to bench bleed the brake master cylinder before installation. My fluid was very contaminated so I used this opportunity to dump all of it.

OK, makes sense - I will proceed with the assumption that the brake master cylinder is the culprit.

I will do a liitle more digging, just to make sure that i have everything i need - too bad Ford doesn't offer up this information freely to it's customers. I just can't have anything go wrong - no car means no work!

You could easily be getting ready to crash your car into others at a traffic light, worrying about having to have car with no downtime is definitely misplaced priority..........getting car fixed fast is more important.

Change master cylinder.

I haven't done repairs as of yet. I haven't really driven the car in a while, but when I have this problem has not presented itself.

If either of you decide to replace your master cylinder, do yourself a favor and bench bleed it before installation. There are kits for that with little threaded plastic plugs. If you install the cylinder dry, fill it up, and bleed everything from the brakes, it takes longer and you waste fluid.
