There is a number of parameters you should pay attention to while evaluating your new brake pads quality. All these parameters are usually linked to friction material formulation and manufacturing process. Manufacturer always has to sacrifice one to benefit another. That is why you need to look into a number of characteristics to value your brake pad.
Brake pad must not only create a sufficient grip with a rotor but the grip must be constant, be less effected by rotor temperature and equal to your pedal touch. All these together will give you a nice and sensitive pedal feeling which is very important in today’s heavy traffics road conditions and jams.
Overheat Recovery (Fade)
The brakes must have fast enough heat recovery for your safe drive. You can try it by applying multiple emergency braking while moving down the hill. Usually braking force will decrease with each subsequent braking but brake pad must have sufficient grip even on the last braking.
Damage to Disc Rotor
All brake pads have some effect on rotor , but some manufacturers do not pay much attention to it, leaving it to the end users’ to take care of brake rotor replacement costs. Getting a “Rotor friendly” brake pad without loosing in all other features is not an easy task to do for manufacturers, but it is of big benefit for the end users who are definitely concerned about total-repair-cost.
Noise and Vibration
It is easy to find out if your brake pad has noise or vibration but you must make sure that it is caused by the brake pad and not by other factors such as wrong installation or poor rotor condition.
Wear Off (Life Time)
It is one of the main concerns of the end users, but you should not forget about other important features as mentioned here, especially Damage to Disc Rotor.
Many manufacturers use extra carbon graphite in their friction material formulations for the purpose of lubrication and cost reduction. This component produces a lot of black dust which in it’s turn makes the rims of your car look dirty within a very short period of time. By switching to TOPLINE brake pads the problem of dusty rims will be almost completely eliminated.
Important to Know:
It usually takes around 500 miles of driving on newly installed brake pads before they are turned into fully “cooked” normal working condition thus, you should not rely on the first impression and should allow the pads some time to reach their optimal level performance which last till the very end of their service.
Changing the Brake Pads is a simple job, but there are few important things usually missed or forgotten by installers, what can lead to noise and vibration and usually brake pad quality is to be blamed for it. Brake pad is most important component in braking process but even a best quality of brake pads it is not enough to absorb all vibrations if it costs by condition of other parts in braking system or improper installation.
If rotor surface is uneven or damaged or has a grooves over 0.3mm depth it needs to be skimmed or turned by using an on-car lathe or taking it to work shop, otherwise your new brake pads will not have a proper contact with rotor surface and that will lead to noise, vibration and fast wear off. If rotor is in good condition it still important to sand the rotor surfaces on both sides lightly with a piece of sandpaper to smooth the surface and remove any residue or pad adhesive that was deposited from the old brake pads which could contaminate the new pads. An orbital sander works well for this job, since it gives the rotor a non-directional finish recommended by most car manufacturers.
Places to be lubricated: – Back plate of pads at the edges and in the centre where cylinders push. Holding Clips. – Caliper bolts (pins). Make sure that lubricant will not contaminate friction material and rotor braking surface.
