WHY SHOULD I CONSIDER FITTING BETTER BRAKES?
There are many reasons to fit uprated brakes, but the main two are
speed and safety. If you want to drive fast, you need to think about
more than just engine tuning. Brakes are just as crucial for
point-to-point pace. Safety should also be at the forefront of your
mind - after spending so much on your motor the last thing you want to
do is write it off due to poor brakes.
2) Brakes work by turning the energy of forward motion into heat.
The more heat your brakes can generate and cope with, the better their
ability to perform at a high level.
Your increased point-to-point
speed will come from the ability to brake harder and later, gaining a
massive advantage over cars running standard discs and pads. On a
real-world run, covering twisty A and B roads, the advantage of uprated
brakes can be as great as having an additional 100bhp under your right
Uprated brakes can also handle more heat than the standard
set-up - just what you need if you enjoy hard and fast runs or have a
boot full of heavy ICE. The ability to handle more heat means your
brakes will last longer before the dreaded fade kicks in. Fade happens
when the system is over-heated - once you breach the set-up`s
temperature range the pad compound melts and glazes over. This loses a
huge chunk of performance - right when you need all the performance you
Discs can be drilled (for water and gas dispersion),
grooved (for gas and waste pad material dispersion) and dimpled (to
prevent pad lift due to gas build-up). Some of the most expensive discs
combine all these attributes.
Pads use various friction-compounds - some have a higher abrasives content while others have extra lubricant.

discs and pads will have a working temperature range. You need to
ensure your combination offers maximum braking performance at the
temperature your car generates when being driven hard.
A Pug 106
will not require brakes that offer maximum performance around the 1000
degree mark because it`s unlikely you will ever generate this amount of
heat. Whereas a 500bhp Supra would melt a set of discs designed to work
at their best around the 300-degree mark.
Ask your performance
tuning specialist what discs and pads they think will ensure a good
match with your driving style and car`s performance.
WHAT BRAKE SET-UP IS BEST FOR TOWN USE?
On a car that spends most of its time rolling around in traffic you do
not want a system which requires a high temperature to work effectively
- as it is unlikely you will ever generate the required amount of heat
to get them working properly.
A set of grooved discs will do the job nicely and will look great behind a set of open alloys.
2) On a town car your best option is to use a low temperature, highly abrasive pad, in conjunction with a grooved disc.
highly abrasive pad will offer great stopping, even when cold. And the
grooved disc will keep the pads` surface square and clear of any glaze
3) Town Set-ups
Ask your performance tuner for a set of well matched low-temp pads and grooved discs.
discs may well come with a nickel or zinc coating to prevent rust, but
this can take up to four hundred miles to cut through. On a town car
this could mean a good few weeks before the brakes perform at their
best. To speed the process up, ask your dealer if the braking surface
of the discs can be lightly buffed.
WHAT BRAKE SET-UP IS BEST FOR HIGH SPEED USE?
On a car which spends most of its time cruising at high speed, you want
a system which does not require a high temperature to start working,
but one which will also handle the high temperatures experienced when
braking from high speeds.
A set of drilled discs and medium temperature pads will work wonders.
2) On a motorway stormer a set of medium temperature pads will bite
early and cope with quite a bit of heat generation - so even after a
long period of little use they will still be effective and once hot,
they should suffer little fade.
The drilled disc will keep the pads
from lifting off the disc surface due to water splash or gas
generation. They will also help the set-up cool quickly and reduce
glaze build up.
3) Mild-road Set-ups
Ask your performance tuner for a set of well matched medium-temp pads and drilled discs.
with a nickel or zinc coating will hold rust at bay, and as you do so
many miles it won`t take too long for them to bed in.
