Absolutely agree. In my humid part of Texas it's amazing how much atmospheric moisture brake fluid absorbs from the small head space over the master cylinder reservoir, and how that moisture can collect and promote rust in the least convenient crannys of the brake system (not to mention cause issues due to it's relatively low boiling point and relatively large temperature-related expansion characteristics).Brake fluid doesn't "wear out" or "expire", but it does become contaminated over time which could reduce braking performance or damage expensive components like the VSA modulator.
Most all "guidance" for vehicle PM is based on considerations of 'typical' ('average'?) situations with 'conservatism' applied if the atypical situation presents significantly greater risk (a form of sensitivity analysis). That guidance is much better than nothing and is protective for the vast majority of situations encountered by the vast majority of consumers.What I don't understand is how they can make blanket intervals for brake fluid as I would think that the climate you are in must be a factor.
One might wonder about his tolerance for the effects of miles and age. Some folks genuinely don't care as long as it 'drives' (and that's fine for them ).I have a friend/ ex-business associate who even though he makes a huge amount of money buys ( never leases) Infiniti's and Acura's and drives them until the wheels fall off at 200k miles doing minimal if no maintenance other than gas,oil and tires. He ticks me off when he says " yep I drove this 2001 Acura for 200k miles and never did anything but change the oil and new tires. Either he is lying of we are all nuts???
Agree. He might just be lucky.( He seems to be in other areas of life as well. )He is not a "car guy" by any means. He does enough research to stick to reliable Japanese brands and just literally drives them until the wheels fall off with little to no maintenance. His last car was a 2007 Infiniti G35 which he finally got rid of last year at 220k miles and claims he did absolutely nothing but change the oil and tires at the highest mileage limits. Now has an Acura MDX.One might wonder about his tolerance for the effects of miles and age. Some folks genuinely don't care as long as it 'drives' (and that's fine for them ).
There's a lot of ground between no-PM and "overly concerned"; everyone just needs to find their comfort zone and hopefully not be too pedantic or condescending to others who might have a different one. IMO.
Transmission fluidI just find it odd that on a new Honda vehicle like the Ridgeline the recommendation for replacing transmission fluid, transfer case fluid, rear differential brake fluid and even a timing belt at 60k miles are so short. I should have done more research. The 10 year old Toyota Tundra I had never needed these items addressed. This will probably end up being a 3 year vehicle for me as much as I like it.
All well worth it to me, the occasional cost and effort pales in comparison the the enjoyment returned by the RL day-in-day-out, just as the overall features of the competition pale in comparison to the RL.Because of the Ridgeline's more advance AWD drive system, it requires more maintenance than a part-time 4WD system.
"The clutch packs and their friction material are carefully designed to withstand the small amount of continuous slip between front and rear axles created by the 2.7-percent speed differential—all while delivering the durability expected of a Honda product."Please repeat that part about the rear diff. Admittedly I ASSumed it operated like my early Pilot, in the sense that the rear isn't driving at cruise unless needed. So the new system is always driving the rear wheels?
With the exception of the 10-speed, Honda automatic transmissions aren't like others. Instead of using planetary gears that are engaged or held with clutches and brakes, Honda's automatic transmissions resemble manual transmissions internally in that they use parallel shafts, but with friction clutches between gears. In order to maintain shift quality and longevity targets, specific fluid must be used and changed when prompted by the Maintenance Minder which calculates transmission fluid life based on actual operating conditions.
Transfer case fluid
Because the Ridgeline is an AWD vehicle instead of a part-time 4WD vehicle, the transfer case is always working so it needs more frequent fluid changes. On part-time 4WD vehicles, the transfer case isn't doing much, so the fluid doesn't require maintenance as frequently.
The magic behind the Ridgeline's capability on low-traction surfaces and sports car-like handling due to torque vectoring comes from a unique "differential" that technically isn't a differential. It's actually a right-angle gear drive with clutches between each output shaft and each rear wheel that can be modulated from completely off to fully engaged. Because it's always driving the rear wheels even on dry pavement, it's always generating heat and loading up with clutch material. The open or locking differentials on part-time 4WD vehicles don't have friction clutches that are always in use, so they don't require maintenance as frequently..
The 60,000-miles replacement interval is recommend only when driving regularly under specific, extreme conditions. Otherwise, replacement is per the Maintenance Minder which tends to be about every 105,000 miles.
