Re: Front rotor problems

I need help!! I just changed the rotors and pads on my 04 mazda3 s. The rear brakes are woking fine, the problem I am having is with the front brakes. The pads only seem to be gripping the top part of the rotor. I bled the brakes, but this did not resolve the issue. Does anyone have any ideas??

Re: Rotors and Warping

This helps me out a little but I am still not sure if I should just replace the rotors in the front to c/s rotors or just have the OE ones machined down. I am starting to get a heavy vibration when I hard brake from 100 mph down. What can I say I love the street racing and since getting this car it has only become worse. The vibration started about a week ago and my buddy keeps telling me my rotors are warping. Any suggestions or should I take it to the dealer for a check-up?

Re: Rotors and Warping

Oh and if anyone has a good suggestion about a CB Exhaust, I welcome your opinion. I was looking at Vibrant downpipe & CB exhaust listed on mazdaspeedstore.com but not sure about that since I am not to familar with it. Any ideas??? otherwise I will still with a name I know and get the Borla CB but from what I can tell it does not include the downpipe which is what I am reading as the biggest problem for stock MS3.

Re: Rotors and Warping

I need to change my rotors now; they are so badly warped!
Does anyone have suggestions on some really good ones and where I can purchase them?
I don't want to buy stock.

I need some that are going to last. I drive everyday in stop and go traffic!!!!!!

Thank you,
Linda

Re: Rotors and Warping

keep your wheels torqued evenly and I kid you not the difference in time that the rotors last before feeling warped is significant. I personally run cheap rotors even on the race car and have never cracked or warped a rotor yet.

I have always had really good luck with the Powerslots. You can get them at Autoanything or TireRack.

Cheers,

Enrique

I get my tires rotated and balanced on time I am assuming that they torque my wheels correctly. Is there anyway of me checking them myself?

Re: Rotors and Warping

Get a torque wrench and a deep socket that fits the lug nut. Torque specs can probably be found in the owner's manual.

Yeah... one of the HUGE things missed is that we have seen in repeated experience that unevenly torqued lugs cause 90% of the "warped" rotors. I've seen it over and over on my own car and others!

BINGO!! I couldn't agree more, and I too have seen it over and over.

Did I say that he's 100% right? Well, he is! :P


Just because a tire shop installed your wheels and said that "Yea, they're torqued correctly", don't believe them.

My neighbor got some 23's for his Titan, installed by America's Tire. We were looking at them and he said that on the way home "His steering wheel shook a little" and it didn't do it before the new wheels, so I mentioned proper lug torque. That led to me checking his lugs, and on every wheel, one lug was over 120ftlb's, and the other lugs ranged between 75-100ftlb's. :shock:

I loosened all the lugs, then I torqued them to Nissan's spec in a criss-cross pattern, and his steering wheel shake is completely gone. Oh yea, I sure enjoyed the tacos and Corona that he bought me for fixing his problem. :P

BTW, he bought his own torque wrench, and he brings it with him when he gets his tires rotated, and he makes them use it while he watches.
