I am working on the GSR getting ready for my next HPDE and once again my rear rotors are warped and need to be replaced. I am thinking this is caused by the heat and I wanted to pull off my rear dust shields. Here is the pain, I have to get that damn nut off to pull the hub out to take off the shield. Is this exercise worth it? I can imagine the fronts are more crucial than the rears. What do you all think?

Thanks!

 

Haven't done this on an Integra, but a clean removal on an S2000 requires similar steps. A pair of tin snips strategically used makes the job a lot easier.

Some advise wrapping any rubber boots in close proximity to the exposed rotor with insulating tape.

 

If you're rears are warping, I would guess that it's due to a siezed caliper so that the brakes don't release or something similar. I highly doubt that during normal use you could heat your rear brakes up enough to break anything.

Before I sorted my rear calipers out, it was extremely difficult to turn the rear rotors with my hands when the wheels were off. I would check that, especially if you've got the car up and wheels off anyway.

 

Could it also be from using the e-brake before the brakes are cool?

 

I do not use the ebrake at all to prevent this from happening. I did notice that the brake pads are wearing unevenly though... I believe it is because the pads are a tad too large or the retaining hardware is no longer any good. Do most people sand down the ends of the pads if they are sticking?

 

I've been running the same rear discs for 3 years with no warpage problems, probably 2000 track miles. I still have the dust shields on the back, in part because they are the mounts for the ABS sensors and also shield them from debris.

It sounds like you may have a problem with the fit of the steel backing plate part of the pads. It is common for the stamped steel part to have crooked edges from the stamping process. I generally use a file to square off the edges until the pad will move smoothly in the carrier. If the pad cannot slide easily, it can become jambed against the rotor and overheat.
