I got 160k on the brakes on my first gen camry hyrid. The rears were wiped out, the fronts had 4mm left. I replaced them all and the rotors. I would like to get another 160k out of them.
I remember doing like you did here and putting the back of my fingers on my rotors to see how hot they were after driving (not a hybrid). Stupid I know, but I was curious. Needless to say, when I did my fingers did a "tssssss" sizzling sound and I yelped. Never done it again since 😂
Tom, do you know how the assembly plants manage to put tens of thousands of cars on the assembly line under AC vacuum then charge them all precisely and check for leaks? It'd be neat to see how they are able to pull this off... Thank you!!! Freddy in Arkansas
@@freddyhollingsworth5945 it’s all done by time really fast. Just like they fill up Coca-Cola bottles in an assembly line PLCs control everything . If all components are exactly the same and all components are assembled the same no need for leak checking except periodically check quality control sample size Industrial sample size products are sampled so fast and so precisely .
The friction braking on my “C” does so little. Once in a while I intentionally slip the shifter into “N” (which disables regenerative braking mode) on a downhill grade to exercise the Calipers & Wheel cylinders. Although I don’t think it is much of an issue on Toyota product. The concept of “hilltop” charge limitation is also interesting. The HV battery management system typically never charges to 100% capacity. Not only as a battery longevity strategy but also to preserve headroom for regenerative braking purposes. If the BMS permitted 100% charge, regeneration would have to be rendered inoperative (regen inhibit). Full bucket, no more capacity analogy. 😁
@@TheGibby3340 I have filled up the buckets coming downhill many times And you 100% lose your regenerative stopping . It downshifts and whines the hell out of the engine . It’s better to use the brakes. Listen to your engine sound like a blender on high speed.
@@coldfinger459sub0 I have never experienced that scenario ever…But my geography is relatively flat. Very different from Lombard St. 😁 Prius has 2 motor/generators (M/G’s) as you know. I believe there are conditions where one M/G can be in generation mode, its output used to motor the other M/G via the planetary gearbox. The scenario you describe might be it…not sure 🤔
@@TheGibby3340 Toyota's grounding is engineered to fail. No heat shrinks between the ground terminal and copper cable to prevent corrosion between the mating surface. The bus bar connecting the hybrid battery also has corrosion issues on earlier models. The cost of an OEM battery is ridiculous.
When you're fully charged while driving downhill, MG1 uses the excess energy that can't be stored in the battery by spinning the engine. This is why you might hear the engine revving up after a long downhill descent.
Hi Tom!! What is your thoughts on AC compressor slugging in cars, especially ones that are way low down. I was reading the shop manual on my 03 Lincoln Town Car and see that for 03+ they added an anti-slugging logic to the PCM...sure enough upon turning on my AC it'll rapidly short cycle the compressor, on 2 sec, off 4 sec, on 4, off 2, then regular operation... Thank you!!!
@@freddyhollingsworth5945 it’s no different if the cylinders were filled with liquid. And you gave it a few short, eighth of a turn at a time with your hand into the liquid, was forced through the Reed valves And then you engaged at 100% afterwards You’re just clearing the cylinders using quick cycling

@@JohnFrazier007 I did that when I was a kid. Only once
Just make sure to keep enough distance just incase the engine stalls.
Forget to mention about the recall just after the plandemic.

@@TheGibby3340 yes all scenarios are possible accelerating, using motors and engine, simultaneously or accelerating and charging.
