Q: diskrotor vs. brake pad
|
got me a new front rotor and fresh brake pads for my WR450F from a
yamaha workshop. After a day of riding i find the pads' friction
track barely covers the center section with all the holes but leaves
an area of almost 1/4" on the very outside of the rotor AND another
1/4" on the inside totally unused!
Is that okay?
I think i remember the package said genuine Yamaha pads?
(can that be? is there something like yamaha packaged pads?)
Should i try and get me "wider" pads so the rotor surface gets
more coverage?

Rowdy,
I don't know the answer there, but I'd think it would be normal that they
would need to leave some meat on the inside and outside undrilled for
strength. Then, take the next step and heat that baby up with lots of hard
braking. You'd want all the heat in the vented area, not some in and some
out which might lead to temp. differentials and warping problems. So, your
situation doesn't sound abnormal. Maybe. Just guessing. I flunked
Thermodynamics but I had already made the childish decision to stop trying.
You rode for a day. How were the brakes?
Now, on to my own brake rotor situation. I have to put front rotors on my
Vulva V70 because they are warped and have served a full life. I found and
have used a very excellent site for parts and they offer me the option of
upgrading to crossdrilled rotors. I'm looking at the Zimmerman components,
crossdrilled or not. I do drive hard sometimes, so the extra brake cooling
could actually be of benefit. Bling factor is not really an issue on a Vulva
wagon. What do I cost myself? Pad wear? Brake noise? Rotor wear?

My very limited experience was a different brand of drilled rotor on
my former GMC pickup. The rotor absolutely wore faster. Or maybe
it wasn't 100% wear but the salted road/normal wear equation made
the rotors get gouged and ratty faster than the stock GM's. About
130k miles on the original equipment stockers, 45k on the drilled ones,
needed new ones when I sold it in January.
Go fast. Take chances.
