Angeles Crest is a lot of fun but yeah not the time to go with the fires and snow. Did it twice when I bought cars out there.

Houston, we have a problem.  Two, actually.

Saw some grease on the inside of the wheel and investigated today.  Appears to be a small cut in the axle boot near the band clamp.  Probably happened when replacing the hubs as it's challenging to get a socket in there with the axle in the way.

Sometimes "an ounce of prevention" becomes "No good deed goes unpunished"


 

And what was once a minor occasional weep in one of the front calipers turned into a full fledged drip.  Enough that the master was low.  Happened after it was 24 degrees out the other night.  
 

I'm willing to run the axle to its death at a track day but not brakes.
 

Will see if the fluid issue is still there tomorrow.  That could be a deal breaker.

Oof. Well, if it can hold on a bit you're welcome to my tools and space if you're headed back through Phoenix.

Brake leak persisted all week so car is back on the trailer and our weekend at Chuckwalla cancelled.  Next year.  
 

Contemplated a heroic field repair with expedited parts delivery, but not worth it.  

Edit: But I did just fix that trailer shield rip with zip ties, just after this pic was taken.  :)

Bumping this back up for a final installment.  TL;DR repairs have been made and the car is back in service.  
 

When I got home I was just about to hit the Order button at Mazda Motorsports on a shopping cart full of fresh parts when I came across a nearby FB sale of never-tracked Brembo calipers and serviceable rear axles at a great price. A quick trip to Dallas and they were mine.

Calipers went on super easy w/o much fluid loss.  So fresh.

Axle was a challenge.  Specifically, removal of the old one.  The retention clip seemed hell-bent on doing its job forever.  Tried all my usual prying techniques to no avail.  

Factory method uses a slide hammer with an adjustable adapter.  I have the former but the latter is $200.  Sorry, no sale. 

Instead, I found a fixed width adapter on Amazon and opened up the gap with an angle grinder to fit.  Once I got it all lined up right, a couple good whacks and the retention clip was defeated.

Offending slit in boot most likely from socket impact during hub R&R.  An once of prevention sometimes requires a couple pounds of cure.

 

All cleaned up.
