I need new pads and rotors up front, I was thinking of cross drilled rotors but not sure if it makes a difference or is it just for looks. Any suggestions?

Just for looks really, unless you're taking it to the track. Theoretically, when it comes to normal street driving, having cross drilled rotors are going will actually decrease the rotor surface area for the pads to bite down on. Cross drilled/slotted rotors are only beneficial under conditions that require repeated threshold braking stops.

Yes, some people are going to come on here and swear up and down that their cross drilled rotors made a huge difference in their stopping distances blah blah blah. Brakes are kind of like tires in the sense that most people only replace them when needed. When you replace worn ass pads and rotors with brand new parts you are going to notice a difference regardless of quality, construction, etc.

I use centrics w/akebono pads No issues. Pure street driving and I'm not hard on brakes. Still have original front rotors with 92k miles. Replaced rears with centrics earlier this year.

The rotors are warped, that's why I need to replace them, I'll probably just get a good set of rotors and ceramic pads. Thanks for the replies

I too have the Centric rotors. Great OEM replacement and come with their anti-corrossion e-coating.

Andrew/RL

I was looking at those on tire rack, I am going to order a set thanks for the recommendation

rlerman

They are cheaper on amazon I think, or they used to be.

Just picked up a set of front centrics on eBay, $38 each! I feel the brakes pulsating at hwy speeds so I'm thinking they are a little warped. Hope fronts are as easy as the rears were. I suspect they are, really just two bolts holding caliper on and the screw on the rotor.

Ill be doing brake fluid flush too, been about three years and pedal feels a little softer lately.

Fun weekend ahead!

On Monday, new tires going on, Versados!

I shut down at the first 12 words.

Tough crowd!

Sorry, man. Not to kill your buzz but there are certain things I don't chance eBay discount reliability on, and safety features dominate that list.

Usually "warped rotors" is due to uneven pad deposits.

DanL07RL

ABSOLUTELY!! There are those who will tell you rotors don't warp. Before you change them, do a run out test with a measuring device. Then you probably can clean the rotors by running strongly abrasive pads for a few miles, then replace those with OEM pads and bed them in properly.

Porsche guys deal with this all the time......just sayin'.

rlerman

All done. There were some decent grooves on the insides of the rotors even though outside looked ok. Easy job, took about 2 hours, including brake fluid flush on all four corners, fluid was very dirty.

On the rotors, they seem pretty good to me. Markings match Centric specs and are etched into the sides. They seem authentic. We'll see. Car stops a bit better, but I bet more has to do with the fluid than rotors. I didn't replace the pads as they are relatively new.

yea fluid makes a big difference.

Did some highway driving today, all pulsating that I felt while brake at 60-75 is now completely gone. New rotors have made a huge difference. I went 95k mile on the originals, prob should have changed them 10k miles ago.

oo7spy

Did you ever have them resurfaced?

rlerman

No. I usually replace rotors rather than resurface. They aren't that expensive.

oo7spy

You went 95k mi on one set of pads?

rlerman

No, only rotors were original. I'm on my second aet of pads. The car sees no city driving, only hwy and suburban, and I'm not heavy on the brakes.

DanL07RL

I went 90K on one set of original pads....possible if you take care of the car.

Those new rotors and pads need to be bedded in....see the article I posted. Not hard to do but nececssary. Just sayin'.

rlerman

I think bedding is more critical for the pads than the disc, and mainly for race applications. I think it's less critical for the street as the compounds are different. Since I only replaced the discs, I'm not too concerned with bedding.

Hi guys !
What do you think about OEM rotors pads fornt and rear?
Are they same quality as after market.
Please help.

Thats a tough question, my car has done fantastic with the brake wear at over 100k on the original rotors. So I would probably go back OEM.

But there are a LOT of factors including the driving style.

oo7spy

This could be your problem. You should resurface your rotors before putting on new pads.

rlerman

My first set of pads lasted 80k miles and my front rotors went 95k. I'd call that very good wear. What problem are you referring to?
