All pads contain some organic (living) materials. Resins that bind pads compounds
together are organic-petro-chemical products. When Brake Pads reach high temperatures, the
resins revert to gas and cause the pads to "aquaplane" on a film of gas (this is
called "fade"). Some pads only fade once or twice and then settle down (green
fade or bedding-in fade). Many cheap low quality pads will suffer from continual dynamic
fade, sometimes at surprisingly low temperatures.
Temperatures between the pad and the disc do not normally exceed 400 -450°C even in
heavy street use. Safeline Brake Pads are heat stable to 600 °C. Blue lines or dots
on your brake rotors are an indication of excessive heat - check calliper condition as
well as fitment clips and pins to make sure that the Brake Pads are not binding on the
discs during normal driving.
Be careful about this. Scored, old or worn rotors can extend bed-in times by hundreds
of kilometres, plus brake performance will be severely reduced during break-in. Renew or,
if with in specification, skim scored rotors. Don't take risks. Our warranty on Safeline
Brake Pads does not cover use on heavily scored or under spec rotors. Reduced contact area
of scored rotors will cause fade and can cause loss of brake. Contact us or see a
professional installer foradvice.
Knowing where rotor castings come from, not just where they are machined, is a major
problem for consumers. There is a wide range of quality on today´s world markets. Not all
discs are equal. Any good quality cast iron rotor will work well with Safeline Brake Pads.
Don't just buy the cheapest or you may end up with a poor brake or a warped rotor.
On light vehicles up to ¾ tonnes and 2.5 litre in street use, 25000 to 35 000km´s is
common. BUT there are many factors that can influence what mileage you will get from any
set of brake pads:
¤ Weight: Overloading especially commercial
applications
¤ Heat: Excessive hard braking or dragging of pads.
¤ Poor rotor and brake system condition.

Safeline Brake Pads have specific formulations that are correct for the front or rear application.
Safeline Brake Pads have an industry-leading friction co-efficient (µ) of 0,4. Many
other brands vary from 0,25 to 0,35. The friction coefficient should be carefully tested
to give you a progressive and confident pedal feel during the brake cycle.
Safeline Brake Pads are formulated and tested for both systems. Fitting Safeline Brake
Pads is a great way to improve older non-servo systems. As a tip on non-servo systems,
always make sure your brake fluid and hydraulic systems are in good condition - it will
give you a better pedal feel.
A vehicle´s brake pedal often feels soft for a while after fitting new pads. Allow time
for pads to bed-in, especially if the rotors are scored. Firmer pedal will return after a
period of driving. Exercise caution during break-in and consult a professional if the
brakes do not feel firm and responsive after 100 to 300 km´s of careful driving.
Brake pads need to be held securely within the calliper to avoid unnecessary vibration.
At the same time the pads need to be able to move towards the disc when braking in order
for friction to occur. It is this friction that slows you down. Once you release pressure
from the brake pedal the pads need to move away from the disc to stop further friction
from occurring.
There are steel springs and pins which allow the pads mounted in tour brake callipers to
move freely without rattling and vibrating excessively. However, due to the dynamic nature
of your brake system, these pins and springs wear and loosen their tension after 1-2
years. Worn pins can result in binding, squealing, brake fade, uneven braking and reduced
pad life.
Yes most definitely. It is vital that the hydraulic system is in good working order.
All calliper seals and hoses should be checked for leakages when the pads are fitted. An
easy way to check is to look for a sticky area with caked dirt, this will indicate where
the leak is coming from in your system. Brake hoses and seals should last 6-8 years under
normal conditions.
