Carbon Metalic brakes caution
I have had some experience with Carbon brake
pads and here are some note:
They don't fad! This is good especially on that
long downhill grade heavily loaded. Keep in mind that you can still epand the drums such that it will reduce the rear braking to the point of fad.
They don't glaze which is nice to maintenance.
They don't stop well when cold. So that 1st
stop sign in the morning can get really
exciting. So can that panic stop when you
have not used them for a while. Like when
you are just cruz'en down the freeway and
someone cuts you off to make that off ramp.
The will wear out rotor and drums much faster
than normal brakes. On my RX-7 it was almost
1:1. Which means that when the pad was used
so were the rotors. Which is a real pain
on the front axel of the 4x4. This adds to the overall expense (TCO).
The are expensive (but a lot cheaper than an
accident!).
You will need higher temperature brake fliud.
I use Moltul which is a Dot3 but 600F rather
than the Dot4 at 450F. I just bleed more often to get around the DOT3 issues.
General note: If there is every any question
that the brake fluid has been around too long
I get another bottle.
Moltul tends to only come in 1 liter bottles
and it still picks up water if opened too long. If you used an open bottle and have just
bleed and you get a soft pedal.
Buy another bottle and bleed again because
it has pick up enough water to cause problems.
I would recommend Carbon Kevlar rather than
Carbon Metallic. They do not require as much
heat to work good. The bedding in is easier.
They are less expensive (~1/2 of Carbon metalic) and are a better compromise for street use.
Do not go with a hard pad.
Pick medium or less for street.
