So this morning after driving my car for a hour I stopped at the gas station and noticed that the driver side rear brakes where smoking..


I could smell brakes...

I just put theses pads on last weekend.. This is the first drive since then..

What could cause it to be smoking?


What should I do or check?

 

does your car feel slower? caliper may be locked?
how hard were you driving?
might also want to see if the pad is wearing evenly. might be too soon for that, though.

 

It did feel a little slower... I try not to use my brakes much..

after putting the pads on last weekend i got them off after a 10 minute test drive and i noticed that it was wearing more on the upper edge,..

is that normal at first?

 

The pads might not be seated properly.

 

I had a similar, if not the same, issue with mine.

I noticed that the rears were at least as hot or hotter than the fronts as measured with an IR thermometer (which is still the case and very odd), but at any rate I also noticed the outer edge of the rotor was showing more discoloration than the inner part of the braking surface.

For me, it turned out to be the tempered steel spring type device that is designed to keep pressure on the pads to keep them pushed in toward the CL of the axle.

Check that. I removed it and re-bent it back so that it would produce enough pressure to keep significant pressure on the pads.

Now if I could only figure out why the S2000 has so much rear brake bias........

 

Rear rotors are solid while the fronts are vented

 

I doubt this is your problem, but is the e-brake releasing completely? I had an issue with that on a Miata a few years ago. GL

 

Come on man, obviously.

I have never had a vehicle where the rears were as hot or hotter than the fronts during aggressive driving.

I was just pointing out that I think it is a bit odd. Other than letting me know they are not vented, can you shed any light on why this may be happening?

I did check the ebrake as well as the calipers for ANYTHING that would cause binding or them not to release. They don't drag either, so again it seems to be the way the brake bias is designed.

If I am not mistaken, there are others on this forum that have even discussed brake ducting for the rears due to this.

 

Another thought is: Did you bed the brake pads properly?

 

Those same people either have bbk's and brake ducts in the rear or have brake ducts front and rear.
My only guess is that with an almost 50/50 weight bias they can take advantage of more rear bias than a car that's let's say 60/40?

Wish I could give you more than that but that's all I have, try posting that question in the racing and competition forum
