Do I really need a fuel injection service/air induction service?

Brake fluid flush is an important but often overlooked service. The only owners manual that I have seen it specified was for a 1984 Mercedes 300TD. I’ve replaced brake cylinders due to rust and corrosion. If there was flushing done the cylinders probably would have been fine.
In theory old brake fluid attracts moisture that could cause loss of braking performance under extreme circumstances because the moisture boils. In reality I doubt that there could ever be enough heat buildup for this to happen.

Read your maintenance manual and know when service comes due and follow that. You can buy a tire depth gauge and check your own tires and shop for deals. I always stick to why I took it there in the first place and they can list what it needs on the work ticket. My first response to add on service is no, no and no.
scamp
Just buy a brake fluid tester if there is now water in the fluid there is no need to change it.
Perhaps. If the sample in the top of the reservoir is representative of the entire system. If moisture is the only contamination of concern. Water tends to fall to the lowest point. Moisture can permeate through the rubber hoses and rubber at the calipers and wouldn’t make it to the reservoir. Every time I have rebuilt a cylinder there was black particles there. May be particles from rubber wear. Flushing would help remove it.
if you are really that concerned about the carbon build up and going spend $300+ for a fuel injector flush i would recommend just doing a walnut blasting on the valves instead. or the good old sea foam method through the intake.
😂 LOL. Having California plates in states being overrun by people escaping the political environment in California could make your vehicle a target for unwelcome attention.
Just did another Harley today. Made a dozen runs to the rev limiter at various throttle openings. Sounded great even thru my Decibel Defense hearing muffs.
Tuning: $400. Decarbonization: free.
that is perfect way to break in the engine and gears !! freeway runs at 4am but on a dyno is nice i can rev every single gear up and let it back down.

Was told the same about the valves and carbon buildup with the usual replacing the engine and internal air filters. I passed on the valves treatment as i only have 11000 miles on my 2020 rav4 limited. But did have a big problem with the power lift door as there were times when I had to push it open or push it shut. The tech took a look and found that the two bracket holding the door to the cars frame were both cracked and will have to be replaced . Under warranty though thank goodness! My thought though is did they crack because of my pushing and pulling on the door when the struts simply were failing. Noticed others with the same problem.

Out west, we call that a freeway.

a dyno is like a treadmill for the car
I had a Triumph 650 Bonneville that pinged really bad with the timing set properly. I put in 105 octane Avgas. This eliminated the pinging. I drove it really hard for a couple of tanks. After that it ran fine on 93 octane fuel.
Can't do that there in Honolulu without running into someone even 50 feet away.
You can take a sample from caliper bleed valve.

I've owned cars where a three year brake fluid flush and refill was manufacturer recommended. And was a requirement of the track within two weeks of any high speed event no matter the age of the car.
My son owned a Mazda where he spent thousands on the brake system after years of brake fluid neglect. Isn't like the old days where the brake shoes were mechanically moved. Today's systems are complex with many sensors and are expensive to fix.
Choose you own interval but don't just neglect it entirely.
