Why not? I drive my car with ducted hood in the rain. Mine just having a center duct actually puts a crazy swirl pattern of the rain on the windshield. It is usually parked outside too.

Finally completed part 1 of my brake change. Started Last Thursday!
Nothing fancy, just normal brakes for a 2013. Bought the parts Wednesday, started on Thursday after work by pulling the rears... Well attempting to; they were stuck. Turns out I was sold the wrong rear rotors anyway (non-vented). Put everything back on, looked up the threads for the 2 bolt holes to push the rotors off. Went to the store to exchange the rear rotors and bought the required bolts. Well, the right rears weren't in stock so they had to order them for me to pick up yesterday.

Went home and proceeded to pull apart the fronts (this is still Thursday). Fronts were also stuck on but now I had the bolts. Got the left front off, pulled out the new rotor, "hey, these don't quite look the same size." Sure enough, the new ones were ~3/8" smaller in diameter (see attached photo with inside pad and rotor. No you shouldn't be able to see the pad at all). Re-assemble old brakes. Pack up tools. No time to get back to the store before they close. Messed up plans for the weekend.

Fast forward to yesterday. Get home from work, go return front rotors and pick up new for all 4 corners (store wouldn't do anything to compensate me on what an ordeal they had added to this job, "rotors were already on sale"). Start with fronts again. Rotors are stuck again/still but deal with it using the bolts. Everything is going ok but then I can't get the caliper over the lower pin on the drivers side. Push as hard as I can on the pin and nothing. Pull it out, wipe off the grease and re-insert to see if there's just an air pocket trapped by excess grease. Still no luck. Feels like it's bottoming out. try putting a C clamp on it, tapping with a hammer, no luck. Remove it to find lots of grease on the tip this time. Wipe off and reinsert. Seems to be going a bit farther but not enough. Press with fingers and remove, barely any grease on tip. Tap with hammer and remove; big glob. Repeat tapping of hammer and wiping of grease until pin sits well within the area it needs to. Remove 1 last time to re-grease the sides. I'm now working by flashlight but I finally manage to get everything re-assembled.

Now I have to find time to do the rears...

Then I get to do my girlfriends car.

Did you order a new set of guide pins? From your description, this seems in a need to be changed. Also, I would suggest a little bit of cleaning on the abutment area (wire brushing that).
Also, an anti-seize between hub and rotor may help next time you havr to change.

The pin actually looked flawless, just had some excess old (but not dry) grease jammed down the end of the hole. I didn't hit it hard enough with the hammer to worry about bending it and made sure it was properly seated before tapping it. The plastic (why is there a plastic section?) didn't show any deformation either.

Unfortunately I do not currently have a wire brush (didn't see a hand held one when I was at the store) but I did liberally coat the inside mounting surfaces of the new rotors with anti seize (the outside has a coating but not the inside )

The tolerances and working of the guide pins are not easy to explain here, but a good practice is to change it whenever tgey are seized/stuck. The grease is not responsible for that (grease can get stuckish very cold situation, but it is not what is going on here). I did not yet disassemble a brz brake (if someone has an old briken, I can disassemble and look in details), but I think you’re mentioning that one of the pins has a rubber insert on the tip, this has several functions, including performance during hard braking, noise and so on. Take a look on the piston and pin boots, of looks brittle, replace those.

Also, replace hardware (clips, specially for anti-drag feature, if available)

Ordered a wrap for the car. Just doing the hood, roof, and trunk lid in a geometric pattern. There are so many DGM cars out there I want mine to look a little different. I am also filling in my OE spoiler holes, so now I don't need to paint it, just primer.

I think you're misunderstanding what I was describing. The pin moved freely but was 'bottoming out' on the old grease inside the guide hole. once that grease was removed (pulled out when it stuck top the tip of the pin) the pin was able to go all the way in to the guide hole as well as moving freely.

The pin itself is metal at the end but has a ribbed plastic sleeve for about 1" near the tip. Found a picture of a similar one (no hex portion on ours, just 2 flats)


Piston boots and guide pin boots were good; metal clips for guiding the pads were replaced and greased.

I've done a number of brake jobs on a number of vehicles. That's part of what makes it so frustrating when a simple job like replacing brake rotors and pads becomes a long drawn out pain.

I think I now prefer the setup I had on my german cars; pins are screwed into the caliper bracket and the caliper glided on the pins as opposed to this setup where the pins are bolted to the calipers and the pins glide on the mounting bracket. No way for air/grease/etc to get stuck inside the glide hole.

So you like Conti FSIII (Golf) setup, seems like. Their ZN is also good. I like Colette types for other reasons (mainly related performance).

Now I got what you meant, and I never saw a similar failure, with the grease loosing their properties to a point that becomes a impediment for the guide pin to bottom (i would expect the grease to move and create space).
Whenever I have to rotate the tires, I will take a look on those brakes (I think those are Tokico’s, but need to verify). See if they have anything unusual.
Two flats on guide pin is not ideal…

Installed a Garmin Catalyst. Sometimes I think the Garmin discount I get is a curse. Makes me buy to many Garmin things.

From traveling for funerals, vacation, field work, buying a house and living in general I’ve neglected installing the Edelbrock unit I bought in May(?). Taking a couple days off to do it leisurely. Installed a new led unit in my garage to work w.

Holy crap... you can't possibly begin to convince me that you can see ANYTHING at night time. Especially in CO roads. On top of that, this HAS to be illegal or I'll be mind blown. I guess on the positive side, the BRZ LED's are bright as hell, and may do a decent job of helping you see something...

I'm sure it is not. Drove it at night yesterday and had 0 visibility issues and hit a pretty dark road. Bought a used FRS years ago that had the same tint preinstalled when we got it so we knew it wasn't an issue. Had that car from 2016-2019.

Ok I won't convince you, but we can. It's a little dark in the mountains but this car doesn't see nighttime out there very often anyways. We have a 4runner for that. This is a weekend cruiser. Owned for 2 1/2 years and less than 12k miles. Definitely illegal but cops seem lenient on that. Also, basically every single person in the US with tint on their front windows is illegal. Most tint laws are written that if you have ANYTHING (including stock) on the rear windows you can't have anything on the front. No one goes and removes their rear tint to tint just the front.
