Hey you racer-types:

Why would you chamfer your brake pads?

It can help to reduce chatter and reduce them grabbing when first applied.

Thanks but doesn't it reduce braking effect overall?
What's the point of having 6-pot mega-callipers but then cutting back the
pads to reduce the effect?

 

Chamfering angles/radiuses the leading edge of the brake pad material.

The braking effect is related to the total pad surface area ....not in
having a 90 degree "sharp" edge presented to the braking rotor surface.

Their is a negligible fraction of total contact surface area removed by
angling the edge of the braking material that presents to the traversing
rotor.

One desirable characteristic of the braking effect is consistency of
operation...chatter and sudden grabbing can upset suspension, traction and
also distract the rider's attention budget.

The above response may or may not have been affected by the consumption of
single malt scotch within the prior 25minutes.

Caution should be exercised before applying any of the observations evident
in the above rambling thoughts of apparent consciousness.

 

feck...made speiling mistake so their

 

It should be noted that most if not all manufactures are going back to 4
piston
callipers. One of the benefits of reducing the pad area helps to increase
pressure
on the contact point. A good example is if you go skiing the longer the skis
the faster
you go. Friction is the ability of two items to slide. once the parts are
sliding you
need to increase pressure to stop the sliding. you can put more pressure on
a smaller
part. there are many things to take into account when doing this. If you go
to small
then it has the reverse affect. this is due to the heat build-up. This is
one of the reasons
the wave discs improve braking. They reduce the contact area, this increases
the
pressure that can be applied and the waves allows air to pass between the
pads
helping them to cool. the increased edge surface area of the disc helps the
discs to
cool as well.

Thanks.

erm - Daytona 200

Wheels get replaced very fkn quickly ( we talking 9sec pitstops) & the
chamfer on the leading edge of the pad allows the disk to slot home easier
than hitting on a leading edge of a pad.


Nothing to do with performance, just to save time in them pitstops

 

Ahh of course!
Now why didn't I think of that....
