better to buy new rotors if current ones are warped

by **hari-bhari** » Sun Jul 23, 2006 6:24 pm

my stock rotors are warped at 50k (weird i know) and i get lots of shaking while braking at high speeds. do i need new rotors or would it be cheaper to get these resurfaced.

i was thinking of getting brembo rotors (don't know if having them cross drilled or slotted makes a big difference). should i get all 4 or just 2? i have a v6 so i beleive all 4 wheels are disc brakes.

also whats the opinion on other brands or rotors and should i buy off ebay? i hear ebay sellers buy brembo blanks and then slot themselves, leading to crap quality. do brembos warp easily or should they last me?

Well if your stockers are warped you MUST get new ones. If the stockers are just uneven then get them resurfaced. Autozone can check them out for you.

if the warp isnt too bad it can be machined out. i think you should be able to turn them since they are virgin

get new ones bro, preferably brembo... i replaced all 4 for my ride.

I have never met a warp that could be machined out. Not to say that it hasnt happened but Ive never seen one. Take it to a brake shop and see what they say.

Warped rotors was common with the stockers. I had the same issue and remember reading about several others with the same problem. I bet even if they are turned, they will warp again.

I got powerstop brand. I know nothing about the brand, but they performed well. They were cross-drilled which obviously did nothing for stopping, but looked sort of sporty, I guess.

The rear rotors are verly unlikely to contribe to brake shutter/vibration. I had the stockers at 130k miles.

like that1mexguy said, get new Brembo rotors (non-slotted or cross drilled). I just did my a two/three weeks ago, they're great. The front ones are probably the only ones warped and need replacing.

No really true. Rotors depend a whole lot on how you brake and how one drives. The one's from my 1997 camry are on my solara and they have accumulated close to 135K miles on them (BTW: Camry got brembo's and solara got hands-me-down). And as per visual inspections (and as per autoparts stores) they have close to another 50-75K miles still left on them if propery cared for.

Hari: if your having vibration when braking, then just buy new pads and take those to a auto-brake-store. Have them machine your rotors and replace your pads. If they are indeed warped then the store will let you know about it. I'd say if they are warped, then go about buying new brembos'

For the best value, get new brembo blanks with some new pads in the front, and call it a day.

Replacing the rears is not useful unless theres something wrong with the rear since the front takes on about 90% of the actual braking load.

and slots and crossdrills do nothing for stopping power, but costs more and increases wear.

Been on my brembo blanks for about 2 years now, no maintenance.

sucks to hear that the brembos still have the rusty crap on the outter ring

by **hari-bhari** » Thu Jul 27, 2006 5:56 am

is it ok to stick with the current pads for now? i think they have a good bit of life left in them because they dont squeal or anything. i was thinking of just getting brembo blanks for the front for now, and leaving everything else as is

by **shocar4** » Thu Jul 27, 2006 6:02 am

i would change the pads also! your pads might have been affected by the warped rotors so you need to change them to be safe!

by **Wang2k** » Thu Jul 27, 2006 8:59 am

rotors dont need to be replaced uptil they are at the minimum thickness.

the minimum thickness is stamped on the rotor in either MM or thousandths.

its a waste of money to buy new rotors if yours are servicable.(i learned this in AUTOMOTIVE BRAKE SYSTEMS)

the reason i know you can reuse them is cuz i did a hard stop from 130 to 70 one time and it completely warped my rotors bad. and they still machined out with some meat left to spare.

^^^^i agree 100%

by **hari-bhari** » Thu Jul 27, 2006 2:58 pm

well i was thinking, i could get a new set of brembo blanks for my fronts for around 100 bucks. what's the cost of getting the current rotors serviced? i figured the brembos would be a better investment than spending money on the current ones because they would last longer and wouldnt warp as easily...or do they?
