My googlefu is horrible, I can't seem to find the thread for this. What do guys recommend to do on this?

In the past, I always got the rotor resurface for at least once before getting a new one. Even with the new one, my mechanic always resurface it and I can hear the unevenness on the mil. But this was back in the early 2000s and for my old car, so not sure how new products are different since. Do I need to get it resurface if I go with a new rotor?
My adviser at local dealer said to resurface the front rotors, and for the rear, just slap in a new brake pad and skip the resurface. Is this true? My car is at 70k now, and it shakes pretty hard at high speed when applied the brake. I been reading the forum for the previous gen, people recommended go to rockauto and get raybestos or centric rotor. Would oem brake pads be fine if I do go for new stuff?

 

it is based off of measurments or the rotor thickness.
the dealer or whoever is resurfacing your rotors will measure the thickness of the rotor and then resurface accordingly.


the rear rotors dont get that much play, as the car is set up to brake moreso in the front...thus your dealers thinking. but if they havent measured the rear, then they are just guessing.

 

Thanks justnspace. Now I need to find the spec sheet and measure lol. I also read that after resurfacing, the rotor will warp quicker again. Is this true?

 

Resurfacing any rotor will grind off some metal; by definition, any reduction in metal, also reduces thermal mass. The lower the thermal mass, the higher the probability of the rotor overheating.

Regarding resurfacing new rotors; ever since I switched to using Centric rotors, I've never had a new rotor resurfaced, and never had an issue with pulsing. From an engineering perspective, that is trying to prove a negative with a positive, basically a non-starter. That said, my preference is to buy higher quality new rotors and not grind off any metal; that and I stopped having used rotors resurfaced back in the 1970s; just too many issues with the thinner (but still above min-spec) rotors.

 

Usually it is the other way around. Replace the front rotors and pads as they do most the braking. Resurface rear brakes and get new pads. However check the measurements first.

 

Cool, thanks for all the inputs. I'll just go with new rotors in the front and see if I really need to do the back as well. Gotta make sure I google enough info for that ebrake stuff for doing it at home.

 

Rotors are so cheap, I don't even bother resurfacing anymore.. I just replace them

 

I replaced my rear brake pads after around 100-110k or so miles. The fronts will need to be replaced sometime later this year (assuming I'll get to actually drive anywhere...lol) or next year. These brake pads and the pads in my 3G seem to last forever, so I'm always replacing with OEM pads. Haven't had to replace the rotors yet.

 

Thanks! forgot to ask one more thing. I read here something about with aftermarket rotors, should be use with aftermarket pads instead of of OEM. Is this true? I kind of don't get why. Maybe I'm reading it wrong?

 

No, definitely incorrect. It matters not whether you use OEM rotors and aftermarket pads, or the other way around. They all work.

 

thank you all =) gonna start ordering parts to replace the rotors and pad next week. Hopefully I won't be needing to replace the rear. Still iffy about the ebrake lol

 

I haven't done my own brakes in a while. But I have to agree that rotors are so cheap, just get new ones. You don't need the fancy cross drilled ones, just good old solid rotors. I think I also used Centric once too. Good solid product, no pun intended.

Often when folks feel a pulsing in their brake pedal it is from an uneven coating of pad material on the rotors. This can be fixed if you just bed in your pads. Just give it a google search and you'll find plenty of bed-in procedures. Just don't over do it or you'll have cherry red rotors (I did that once on a BMW, after just replacing the pads and rotors I did it all over again! )

 

Thanks Rocket! I just got my parts from oemacuraparts. I got the pads from them and ended up with the rotors as well. The price is not bad at all, very close to a aftermarket blank rotor. I did not order the clips, which I believe I can reuse them without any issues. Am I safe with this?

 

So I haven't done the brakes on my TLX, I'm talking about my older TSX. But if you mean the clips on the side of the pistons to guide the pads? Yes you should be able to reuse they. You may want to clean and relube them with a little brake grease. Careful not to get any on the pads of course. Also use some anti-squeal on the back of the pads.

 

yup, that's the clip I'm talking about. Thank you =)

 

Anyone know where I can get all the torque spec for the suspension area? I googled and found some pictures but it not for the TLX. Found some for the TL and ILX instead. Are they similar?
