Better pads will make more dust
. If you drive a car fast it will need X drilled disc's. A freelander although requiring a larger force to stop than a smaller car doesn't generate heat as mush as a car driving faster. Speed is actually what causes excess heat in braking. For road use the best way to increase stopping power is by going bigger,, X drilling and grooves will only assist vented disc's dissipate the heat faster. You won't be putting the car through the high speed braking and then high speed runs needed to make all that work much better than standard. Buy quality OEM parts and you will find better braking. Get larger diameter disc's and pads if you wish to up the way your car stops. But be warned causing it to stop harder will throw the cars weight around more so make sure you have good suspension or you may find yourself being overtaken by your back end if you brake hard. If you are finding standard brakes too weak try driving slower or braking sooner. When brakes come to the end of their life they can often feel like you need better than standard. Replace with quality then see how you feel. To improve on standard braking will really require a caliper swap on a big vehicle.
Sort of correct but not entirely
Speed isn't the key feature in heating up brakes. Energy removed from the vehicle is what heats them up.
A given mass at a set velocity will produce X amount of heat in the brakes.
Now increasing the same vehicle's velocity will heat the brakes faster and hotter. Reducing it's mass will reduce the energy dissipated by the brakes so they will be cooler.
So technically a smaller car can drive faster than a Freelander because it's likely to have a lower mass. This means it's brakes will need to dissipate less energy in the form of heat.
To put some figures to this analogy. I did several 80 to 0 mph stop in my ZS180 on a disused runway. I recorded front disc temperature on stopping. This was on standard but correctly functioning brakes. I was surprised to see that the discs got to a tiny 100 °C.
Now the ZS180 has a mass of 1350 Kg's with me in it. But what makes the MG relevant is, the brakes fitted to the MG are the same size as those fitted to the Freelander. Same rotor diameter and thickness and same pad area too.
Now an empty Freelander can weigh in at around 1650 Kg's. That is just over 20% heavier so in a world where energy is a constant, this would mean the Freelander's front discs would heat up 20% hotter than those of the ZS180 in the same 80 to 0 mph stop.
So this would give you a brake temperature of around 120°C after a stop like that. This is well under the 350°C minimum fade temperature of the standard pads.
So technically the standard Freelander brakes are well up to the job.
