I agree it looks like an engine leak from above. You may need a pro to determine the source.
If that is the passenger side boot then you may have the timing cover leak, which is very slow and so expensive to repair it is not worth fixing ($3,000 as the engine has to be removed).
No that's on the driver's side. I'll check the passenger side later this week. Hopefully, it's not a timing cover leak. Those are still an issue for 2013's?
Possible but not guaranteed if it collected enough dust.
It's not impossible to pop up the hood and remove the plastic covers and check behind the battery. If not, climb a ramp at home and use a flashlight to look up.
I changed out the rotors, pads, applied anti-seize around the hub, and cleaned slide pins and reapplied a thin transparent coat of sly-glide lubricant. When I checked the CV boots I didn't notice any new leaks so I'm not sure what caused it above. The only thing I could think of is maybe it's from overspray from PB blaster when I was trying to loosen the bracket bolts.
To be honest this was my first time changing rotors and pads on a car, and I tried following other thread instructions as best I could. I noticed this residue on backside of the new rotors. I tried removing it with brake cleaner but nothing happened. Is this normal? When I test drove my car I went around the block a few times applying moderate pressure on the brakes to try seating them and it seemed to work. They did squeak for about 2 miles but have stopped. Typically after a rotor and pad change is it appropriate to do a brake fluid flush?
Usually rust inhibitors, but brake kleen takes that stuff out really quick. If it didnt probs something else, but I doubt its a problem (not a professional here). The flushes are recommended again depending on the crowd. If your fluid color is not dirty, leave it alone, other folks say change it every 100k. It all depends on what you want and how long you want things to last. Due note, some vehicles require tis or bidirectional scan tools to automate the abs pump to flush that out as well.
Depends how you pushed the caliper pistons back in during the brake job. If you pulled some fluid out of the master cylinder then pushed in the caliper pistons, you should be fine. However. Toyota/Lexus recommends a brake fluid flush/ or fluid exchange every 3 years as brake fluid absorbs water and this can lead to corrosion of very expensive brake system components. It is worth spending the $100 - $130 to have a professional with Techstream do the brake fluid exchange as with Techstream they can activate the ABS and electronic brake force distribution equipment and ensure a thorough fluid replacement with no air in the system. Call around as any shop that works on Toyota's will be able to help you out and the price varies a lot. I had mine done at a Mr. Tire one time.
