Yea, I'd like my next DD to be RWD - I miss the playfulness of it on wet or snowy days. Plus, most RWD cars now are performance-oriented, so you usually get a limited slip diff with RWD cars. Either way, thats a few years out at least.

Most of the exhaust hangers broke off the increasingly rusty Mazda5, but somehow the exhaust itself was still intact and not leaking. I didn't want to deal with trying to disassemble the whole thing to get out the section from the header most of the way back, and of course dealing with the inevitable broken bolts, problems sealing afterwards, and lots of other little problems that come along with rust.


So, time for some in-situ repair. Basically, its just taking one of the exhaust clamps used for holding together slip-on connections, and building something off of the exposed ends of the U-bolt to hang from the rubber hangers. So, some square-section steel tube, threaded rod, assorted nuts and washers, and some aluminum tube to slide over the threaded rod to protect the rubber exhaust hangers, and the result was:






Basically, everything is assembled to make sure the nuts are in compression against something so they don't loosen, and the ones on the end have threadlocker.
Ugh, rust...

So  I replaced brake pads twice this weekend because I ate through two  sets... DE at Mid-Ohio, and I wanted to see how the pads that I ran on  the street (Akebono ceramics) held up. Needless to say... not well. I  destroyed a set of brand new pads over the first day, and some that were  a little bit used in 2 20-min sessions. To finish the last 2 sessions, I  had to run out to a parts store and pick up a set off the shelf... they  weren't great, and didn't grab very well, but at least they were  something. On the plus side, I think they shifted the brake bias to the  rear, which along with the greasy track surface at the hottest part of  the day contributed to the general loose-ness of the car and a pretty  big slide at the end of the video below.

The engine overheated a bit at the end, so I coasted in at the end of that lap. No permanent damage, except the dead brake pads and it looks like the gas gauge no longer reads the top 1/4 of the range... Oh well, the sender is original at 200,000 miles, and I've replaced two of them at less then half that in other cars so I figure it's been over-due.


So, which one is out of place?


Melted tires...


And destroyed brakes...

Looks like the last two sessions of the day, with the replacement parts-store brand brake pads, ultimately did in my driver's side caliper piston. I went in yesterday to replace the rotors and pads, and found that the caliper piston had just kind-of crumbled (at least the outward face). It still is holding fluid pressure, but the boot is torn and the front face is, well...


yea.

Replacing the brakes on Bessie (the manual Mazda5) was also a bit of a bear. The old front rotors were pretty worn and eating through brake pads, and the rear pads were marginal. Replacing the rears went fine, with the only WTF moment being that someone had previously used the wrong bushing for one of the two sliding pins on each rear caliper, which not only bound up very badly but didn't really fit in the hole in the caliper, allowing the inner bore within the caliper to corrode very badly (pinching the pin even more). It took a little while to clean these up, and fortunately the bushings are the same part as on the Saab so I already had a few spares. Oddly enough, the 5 & the Saab also use the same rear brake pads, but the rest of the caliper casting looks different.

Moving on to the fronts, I just could not get one of the rotors off of the hub. It was rusted so solidly that there wasn't even any play to try to work it off or get penetrating fluid in there. Ultimately, this happened...








I was careful not to damage the hub much or lug studs at all, but had to hack the rotor itself apart to get it off. The other front rotor popped off easily, since some kind gentleman of a mechanic put antiseize on the hub before installing the rotor. Who-ever you are, thank you!

I didn't see this before but it reminds me of the nightmare we had on Rich's RX7, except it was both front rotors galvanically corroded/ bonded to the hubs.

oh yea, and getting those rotors changed out was absolutely horrible.

Yea, it was on there pretty solidly. The worst brake job I had was helping a friend with their late '90s Acura CL... In this design the brake rotor is attached to the back-side of the hub flange, so to remove the rotor you had to push the driveshaft out of the hub (which was inevitably very badly corroded), then remove the hub & bearing assembly from the suspension upright. Predictably, the bearing assembly was so badly rusted to the upright that we ended up having to disassemble the whole corner of the car to take it to a machine shop to have it pressed apart, and even then their press wasn't enough to get it to budge without some angle-grinding work too. What an awful design that was...

Wow, that sounds absolutely awful. I'm going to need to replace the rotors on the vert soon, and it's got me nervous.

Lots of little things have happened to the various other cars (and ones in my inlaw's family... went to town on one with a 16 lb sledge hammer...), but the most visually exciting has to be the new wheel color for Annalie's winter shoes.

They were getting pretty badly corroded in spots, causing the original paint to bubble & flake off. Two of them would also develop a slow leak every year, despite having the tire place un-mount the tires and wire-brush the inside of the bead on the wheel. So, since I need to do a bunch of sanding and sealing anyway, why not make them a fun color?





Just got Michelin X-Ice 3's installed on them - I had liked the Hankook i-Pikes that I had before (and they lasted about 55k miles), but they weren't offered this time around. They were good for deeper snow and seemed to keep their composure relatively well on the highway, so we'll see how the Michelins compare.

I like that green a lot.
