Not sure how many of you all out there are running a Wilwood 7/8" bore Master cylinder but got a Recall notice Friday.
If your running one, you might look into whether or not your included in the recalled list

Have you heard anything about what is actually wrong with those masters?

Having a Wilwood on my truck as well, I did a quick search to find the issue and this website had the info, http://www.fourwheeler.com/news/1707...ter-cylinders/

The seal in the front circuit can become deformed on some units making the front circuit fails allowing fluid to bypass the seal and possibly leaving no braking on that circuit. If you have one or know someone that uses wildwood masters let them know.

In short it puts the wide eyed, white knuckled , puckered thrill back into driving.

LOL, puckered WHAT?

that four wheeler article has actual info about the failure mode, first I've seen since this began.

I've seen a couple post that said Wilwood has been getting these units back for warranty for years, ignored the problem.

mine was involved in recall...called them, they gave me a UPS shipping slip...turn around is 2-3 business days...was notified Friday that the master cylinder is on the way back thru UPS and it did not cost me a dime...they were not forced to recall...yet...so far they are doing it on their own

I am disappointed I didn't share this with everyone sooner, I just didn't think about it. A couple years ago mine actually failed. No warning, no nothing, pedal just went to the floor, NO brakes at all. Fortunately I was in a scenario where there was no harm done, it could have been very bad.

I sent my master off to Wilwood because I couldn't find ANYTHING wrong with my system or parts. They told me one of the seals had a little tear. I had them send the old parts back to me along with my rebuilt master, I couldn't tell anything from looking at the old seals. I think they charged me $100 or something for the rebuild.

Then, last year, I got the recall info. I checked with them, they said it was likely I got defective seals in the rebuild as well because they hadn't discovered the problem at that point. So I had to pull it off again, and sent it to them for rebuild. This time there was no charge AND the refunded my money for the last go around.

So anyway, I just wanted to get it out there that this is REAL, YES there have been failures. GET YOUR STUFF SENT BACK AND FIXED!

what he said. Not always second chances on brake fails.
