The easiest way to do it is how I fixed it and it has stayed fixed for thousands of miles. I lifted the truck up at just the affected tired removed that tire before I did. Then I sanded the area where the tone ring sits normally. The reason why the tone ring snaps is because rust gets under it and the cast metal doesn't have the strength to keep together under the stress of that. I put JB weld on where the ring rides and secured the ring with a large hose clamp with the truck parked overnight in a heated garage (winter time). If it is not winter you don't need the heated garage. The JB weld needs about fifty degrees or so to set up well and you will have to be able to leave your truck overnight. This is a good fix for people without a large set of tools and should last longer than the normal fix since the JB Weld seals out the water.

Sounds good. Before I replaced my tone ring, I used 2 part epoxy to temporarily fix it. I had to knock off the epoxied ring, as it was still solid 6 months or so later.

Thanks. You guys/GreenHybrid Rock!

Speaking of rocking, RockAuto.com has this part for my '07 Escape for $4.62 each!

It's got nearly 100k miles on it, so I'll get some brake pads and change those as long as I have the wheels off.

I didn't even have to figure out how to get my laptop's OBDII software to run!

Even though this thread is old, since it comes up on google when people search for this problem I'm going to post some advice.

First of all, you absolutely have to have VCMII Tool from Ford and the Ford IDS software to even work on this brake system. The reason is because there are fault codes like "Brake initialization incomplete" that cannot be reset by clearing the fault codes. You have to run 2 tests, the brake bleed test, and the brake actuator test, to clear this code. So many people get tripped up on this and end up having ford replace the HCU which isn't even bad because of this fault code. I cannot stress this enough, without this tool you can't possibly reset the fault codes.

You can get a clone of this tool on ebay for around $140 shipped to your house, which comes with a cracked version of IDS. If you buy the version from ford it'll cost you $1400 - $2000 for the tool, and the IDS software is $1000 a year. You can also use this tool to replace a bad HCU with a used junkyard HCU. The process is called exhaling and breathing I believe. The IDS software can copy the VIN and relevant data from your old HCU and flash it onto a used HCU.

With the sheer number of used Escape and Mariner hybrids has any company offered rebuilt HCU’s?
