Question about break rotors and pads!?

Could you please explain in details the difference between regular break rotors and slotted drilled rotors. Also could you please explain the difference between semi-metallic and ceramic break pads. How do you know that you should change your rotors (any signs that will indicate that the rotors need to be changed?).

Please serious and respectful answers only. Don't answers if you don't have the appropriate knowledge, no stupid jokes, no nonsense. I have some questions that I need help with so only answer if you can help. Thanks in advance!Question about break rotors and pads!?
Slotted or drilled rotors reduce heat.



Ceramic pads last longer and don't build up the black dust like semi-metallic.



Rotors need to be changed if they are worn badly, or if they cause vibration when the BRAKES (not breaks) are applied.Question about break rotors and pads!?
slotted rotors stay cooler as do the ceramic pad also the the ceramic pads anr quiter as for changing if the rotor has grooves in it then changer them and for pads when they are an 1/8 inchQuestion about break rotors and pads!?
what he said.

you'll only notice the difference if you're racing or driving an some other kind of extreme condition.



As for changing your rotors, you'll only need to do this if you're upgrading or you notice a shudder in the car when you brake. This indicates that the rotors are warped.



If they have groves in them you can just get them machined. cheaper.Question about break rotors and pads!?
Slotted rotors are better than stock rotors...... IF you have a need for them. Slotted rotors vent the gas build up and dust from the brake pads, and are a little more resistant to brake fade. If you race the car or have a specific need for a heavy duty brake system, slotted rotors could be good for you. Ceramic pads are more resistant to the effects of heat, and seem to last longer and not wear down quickly. Rotors should be changed when they no longer meet the minimum thickness requirement, or if they are scored deeply, which would require them to be turned down beyond the minimum thickness. Rotors today don't have a lot of extra thickness. You might get away with turning them once, but then they are more likely to warp when they get real hot, due to the rotor being much thinner.Question about break rotors and pads!?
slotted cool faster which help save the pads life and it does aid in help stoping better and faster in doing so and ceramic is harder and last longer also withstanding a higher temp...



has for knowing when to change the rotors you will need to know the safety spec's but guessing it like five sets of pads more or less depending on how it was drove and if the brake were changed before they did any grinding.... that would vary between cars but easy way to say it would be how thick it was when new and how thick it is when bad and i couldnt give you a number not having a book to look it up in here is some brake info it might help some
