Okay, as I mentioned earlier, I replaced the following at 137,555 miles:
2 front brake disc (Bendix PRT5668, rockauto.com, $39.79)
Set of front brake pads (Bendix CFC1164, rockauto.com, $32.79)
2 rear brake discs (Wagner BD125611E, rockauto.com, $57.58)
Set of rear pads (Bendix CFC1161, rockauto.com, $22.79)
Downstream oxygen sensor (NTK 22129, rockauto.com, $63.79)
I promised to do some videos, but I decided not to. The first reason is that my HOA is on my ass about working on the car and so I don't really have a convenient place to work. I found an empty parking lot nearby, but it's only a matter of time before somebody chases me out of there. It's a lot of working hauling my crap back and forth as well. Filming really takes up a lot of time and I really wanted to be in and out of that parking lot as quickly as possible, and I also had an errand to run at noon. As luck would have it, I had to stop working to run that errand and then continued afterwards.
Some comments:
Front discs/pads: Mazda needs to never ever make anti-rattle hardware like this again. Why in the name of all things good and gracious did they not make the parts out of a single damn piece of steel?!? This damn thing has 6 pieces of metal per side. Ridiculous. This caused me a good deal of delay as I tried to figure out what the heck I was looking at. I eventually figured it out. The separator tool made it a snap.
Rear discs/pads: A much better, simpler design, but, without the separator tool, it would have been impossible to change the pads.
I really wanted to get all the same brand for all the discs and pads, but as luck would have it, I couldn't get all I wanted at the time, so I just did the best I could. They all felt like quality pieces, so I'm satisfied thus far. I did notice one of my front right sliding pins was very very dry and I had to do some fighting to get it out to grease it. In case you're wondering, I used Sil-Glyde.
Oxygen sensor: The NTK 22129 is the original equipment item. Take my word of advice and never, ever, buy anything else. Every single clip that the original sensor has, the replacement has too, and comes pre-lubricated with anti-seize. It's even wrapped with the same green insulation material. I had bought an O2 tool and a 3/8 breaker bar at Harbor Freight, but neither was convenient. I just couldn't position them properly in order to get a good turn. In the end, I just grabbed my 22mm wrench, and in less than 2 seconds, the sensor was free. Zero hassle.
I tried to change the tie rod ends as well, but as hard as I was hitting those knuckles with that 4-lb dead blow hammer, neither would budge. So I'm going to tackle it again, but this time with a proper tie rod end puller tool. But that's a task for another day.
I also noticed that my right rear shock absorber is sweating. I'll get to that in a little while. Needless to say, I will be ordering a set of KYBs from rockauto.com when that time comes.
As for the videos...we'll see.
