a couple weekends ago, be17amin and i had a little brake caliper painting/ headlight clearing/ cai filter cleaning party. when i took my wheels off, i noticed that the front calipers rubbed the rotors if i spun them (i didn't try spinning the rears -- in gear and e-brake engaged while up on stands). i was somewhat surprised by this. i realize that performance brakes are positioned very close to the disc, but actually touching it?

i did not try with the car on ... i'm no brake expert, but was thinking maybe there is a hydraulic difference when on/off. also, we didn't try ben's b/c it was getting late and didn't get to his calipers.

any ideas or personal experience?

thanks,

the caliper itself was rubbing the top or the outer edge of the rotor, or did the pads rub the rotor?

 

Assuming that you're talking about your brake pads, then yes, they are always touching the rotor. Now if you do mean the caliper, then you've got a problem.

 

yup, brakes touch the rotor, ever so slightly, but if ur rotors are rubbing the calipers than i dunno

 

I am wondering if S2000's have any kind of problem with e-brakes or calipers sticking. I just bought one and test drove about 8 (all used) and 3 of 8 had some kind of drag in neutral. Take it out of gear at 10 mph, and 5 would coast freely, the other three would slow like the brakes were partially applied.

They were all in Minnesota but the weather was not so cold that stuff should have been frozen, although many had been sitting for some time.

 

thanks guys ... yes, i meant 'pads' and not calipers. it's amazing, after noticing that they touched, i became convinced that my car was getting less mpg, and that i slowed 'way too fast' when stepping off the gas! kind of a reverse butt-dyno.

thanks again,

vader, the 3 could have had underinflated tires. You'd be surprised how much rolling resistance you find at 20psi.

 

perhaps. It felt like the e-brakes were on two or three clicks but were all the way down when I looked.=. Only one of the three with drag had a slight pull to the right, which could have been from a stuck caliper or low tire inflation.
