Disappointing

We rode the tandem in to work today, and with Wednesday’s trip on it as well, this is the first time we have commuted by bike twice in one week in a looong time.

That bike ride was the highlight of my day. I managed to only finish half of the front brake job I had planned for the Emperor this afternoon. The left front went fairly easy. I say fairly because after 6-1/2 years and nearly 90,000 miles the brake rotor and wheel hub become very fast friends. The folks who make cars know this and they put a nice threaded hole through the disc so you can separate them by cranking down on a bolt screwed in there. But, it takes a scary lot of torque on that bolt before you hear that satisfying pop when the two pieces of metal finally separate. Also one of the caliper slider pins took a bit of coaxing to go back in because with the lube spread on it, the little noise abating rubber sleeve tended to slide out of it’s groove, preventing the pin from fitting in the hole.

On the driver’s side I got the pads off, pulled the caliper and then the bracket off, the second rotor came off easier than first, but then I hit a snag. The top caliper pin was frozen solid in the bracket with corrosion. I sprayed some penetrating fluid on it. Cleaned and lubed the other pin while I waited for the magic. I hammered on the pin and tried backing it out with a 17mm wrench with as much force as I felt comfortable with to no avail. I might have upped the force level by 50% or more, but I didn’t want to break the pin or bracket because we are a one car family and I needed to at least be able to put the car back together and have it operational.

Calls to the Augusta Mazda place, a Miata.net sponsor dealer and Advanced Auto asking about a replacement caliper netted me quotes of from “Can’t Get It” to $185 and we can order it. I then tried the Mazda dealer in Columbia where they still have to order it, but they will sell me just the bracket and pin for less than half the other guys wanted for a re-manufactured caliper and bracket.

I reinstalled the old parts back on the right side and took a drive around the neighborhood to set in the new stuff on the left. The car stops fine, but there is about 4″ more pedal travel. I’m attributing this to the increased travel the left caliper needs to make up for the nearly worn out pads on that side. Still I’ll be taking it easy though until I can get the new bracket and pin on Tuesday.

If that wasn’t bad enough, the motion sensing light quit working again. 🙁
