240sx brake cooling

[dan240]

Hi,

I have a SOHC 240sx coupe that I have autocrossed for years but have never taken to any track days. I have delusions of running it in IT some day. I will be running the car at Willow Springs this month and I am wondering what your guys do to handle brake temps.

With a NA 240sx are good pads and fluid enough? Will I need to remove the dust shields and add some ducting?

I know you guys run with stock sized rotors and I'm wondering if thats enough on this car.

Thanks,
Dan

I don't have any extra cooling on my car, but I'm sure it wouldn't hurt if you wanted to add some ducts. I run blues on the front, hp+ on the rear (poor boy's bias adjustment), stainless braided lines, and use RBF600 fluid. Everything else is stock. I do replace the pads and rotors when the pads are down to about 1/2 thickness, and I bleed the brakes after every session. I have yet to have a problem with fade.

The brakes are good on these cars, but ducting air on them helps. Most of us have at least one duct if not two on the fronts. Other wise see above.

Thank you for the info. That takes some worry off my mind.

Can I assume that most of you guys also run a proportioning valve on the car. (in regards to the "poor boys" bias adjust)?

Best,
Dan

No bias, it's built into the brake master cylinder, so not a lot that you can do except use different pads.

I have been running HT-10s all the way around with no issues.
I have 3" ducts in the front from the factory vents in the bumper run to the calipers.
I plan to do the 8 hr enduro with NASA in Jan. I will update you then on how everything holds up for that time frame.
But all is good for the last two years of racing this current setup.
