My 03 Si, bought new, has 30,000 miles and needs the rotors turned. I am a very conservative driver and as seen by the milage the car is driven very lightly, seldom on the highway. My question is, is it normal to develop warped rotors at this milage/usage? Has anyone had similar issue and/or how are your rotors doing? Otherwise the car is great. Thanks in advance.

Replying to: vviley (Jun 07, 2007 10:16 am) Turning rotors is commonly done every-other brake job or when they need it (pulsing/slight grab of the brakes on gentle stops indicates warped rotors). I used to "clean" the glaze off of my rotors and pads when I noticed grabbing instead of assuming they were warped, but newer metallic pads don't seem to have this problem. Glazing really makes 'em grab! metallics tend to increase warpage, tho. do you brake with you left foot? This is a common cause of premature brake wear, since there is a tendency (albeit unintentional) to let the foot rest ever-so-slightly on the pedal.

| if you can pull the rotors off yourself, having them turned usually runs about $15 each, often new ones can be bought for not much more (non-OEM). It's not worth living with the grabbing. | |

It isn't uncommon for uneven pad transfer to be confused with warpage, which seldom occurs on brakes except by uneven or over-tightening of the lug nuts. OEM brakes are generally noise-free, but also not the best performing by a long stretch. They often don't take heat well, fading around 700 degrees or so, such that one hard, panic stop or lots of hills, curves and stop-and-go will elevate their temperature and cause the pad material to fade, as well as smear and melt on the rotor. These can become "hot spots" that cause the metal underneath to harden, which will cause these areas to wear less than the rest of the rotor and form high spots. Turning the rotor will even up the surface, but the hardening goes deep and the problem will come back. Aftermarket performance oriented brakes are generally much better, but usually noisier (from a little to a lot) and often produce more brake dust, since there is often no such thing as a free lunch. I've been pretty happy with PBR/Axxis ultimates (fade critical at 1000 degrees), but they also make a premium line that offers slightly better than OEM performance for almost no penalty over OEM pads. Other companies like Hawk, also make pads like the HPS (fade critical around 800 degrees), but I've put these on family member vehicles and noticed the warpage issue, especially after the Folks moved from Kansas, with few hills, to N. Kentucky with lots of hills that require a lot of braking. |

I have a 1993 honda civic. The brakes are spongy and pedal travels all the way down before brake holds but only this happens when outside temperature reaches high 80's or so. In the early morning or during the winter the brake holds perfectly. I have bled the system thinking there may be trapped air. Checked the vacuum check valve for suction and is ok. What could it be? Faulty brake power booster?
