No brake dust?!?!?!


Jus-A-CMax

Recommended Posts

So I usually do all the car washing in this house. My Jag was notorious for black brake dust on the rims to a point where I had to buy some special dust-remover spray that I would apply to all the wheels to remove the black crap - that was bad on the alloy (my wifes Jag) but not so bad on the chrome 19" wheels (my Jag which she now drives).

 

However, I noticed that the CMax has got zero brake dust accumulating on the wheels especially in the inside rim. I mean I shove in my long rim cleaner brush and its pretty clean.

 

What gives? Does it not use the brake at all or does Max have some ceramic pads in there?

 

Just wondering if anyone knows anything here. I mean, I  :wub2:  that its way. way less work to clean the wheels and rims now.

I was just saying the other day that I bet we get 100K miles on a set of brake pads.  I did find myself wiping brake dust off the wheels early on, but I haven't noticed any since.

Off-topic, but I love that there's no starter motor to go bad, no power steering pump, fluid or hoses, and now that I think about it, probably no belts except timing.

Regen is nice. Our brakes will last forever because we are reecovering the energy rather than using it to wear out the brake pads. I replaced the brakes in my Prius at 100k miles because I thought I should. It is now over 200K and the brakes are still good. Thoe pleasant side effect, as you have observed, is that the wheels stay clean. No complaint here.

No tranny fluid to change (supposedly) and no changing fuel filters either.

 

Although it looks like you have to take half the engine apart to change the air fliter.

As we drift off topic towards maintenance:

 

1) The cam drive mechanism is a chain.  Yeah, they call it a "belt" on the parts diagram, but the sprockets are clearly chain, the tensioner, the lack of idler pulleys, and the description of other parts as "chain guide" belie the description.  I suspect it is a so called "silent chain," a design Ford has used in the past, rather than a "roller chain" (what you see on your bicycle).  These chains are sometimes called "link belts."

BTW, the cam drive would be much narrower - maybe 4 plates wide, not 13 as shown, - the chain shown in the link is the power drive train for a snowmobile, carrying much more load.  

 

2) The owners manual calls for changing the transmission fluid at 100K.  Unlike automatic transmissions, that have clutches, bands, and hydraulic control valves, there is nothing in the CMax transmissions except gears and bearings.  It's more like a differential than a transmission, and in fact it operates just like a differential, but using epicyclic (sun, planet, and ring gears) rather than bevel (you're old 49 Ford differential) gears.  The demand on the fluid is very low, compared to a conventional automatic transmission.  I believe the front axle differential is inside the transmission case.

 

3) They aren't doing you a favor by burying the fuel filter inside the tank.  It is a response to EPA evaporative emission regulations and is common for virtually all cars since the mid first decade of the century.  If the filter gets clogged, you get to replace the fuel pump (at least), and in some models, the entire fuel tank.
