Right now i have crossdrilled/slotted rotors and hawk hps pads. i hate hate hate it. it sucks around town, it almost feels like it was a downgrade from stock, but what i'm mainly concerned about is when i do a mountain run or something like that, it starts to fade and the pedal starts going to the floor after a few hard hits. could this be cured by changing fluids? my friend has some ATE superblue DOT3 fluid he said he would throw in for me, just wanted to make sure i could use this. a quick search showed that others have so i assume i can.

my next question is, what brake pads to people like? the same friend suggested carbotech pads, anybody use these? thanks, andy

 

I would just try putting in the new brake fluid. Hawk HPS pads are great and I've never seen them be the cause of crappy braking.

 

Motul 600 is another fluid option.

I have Carbotech Bobcats...they are halfway decent street/autox pad. I've had better pads but better also came with some compromises, like horrible dusting, poor cold performance and squealing.

I'd like to try the Cobalts if they were available.

 

That's what I use.

 

When I went drove the Dragon, I had OEM brake pads with Superblue ATE. After 3rd or 4th run (up and down=1), there was definitely brake fade. After a while, I really had to stomp on the brake to stop.

I heard guys running after markets brake calipers to help with brake fade. I think there is a group buy for the wilwood.

 

There is no need to change the calipers or rotors on the S2000 to improve braking performance. You will not achieve greater braking ability, especially with street tires, and even on the track. All you need to do are two things - use upgraded pads and make sure there is fresh fluid in a system that is properly bled. The type of fluid does not matter unless you are tracking the car - then fluids like ATE Super Blue / 200, Motul 600 and Valvoline SynPower will reduce the likelihood of boiling the fluid.

Andy - change the brake fluid, making sure that all old fluid and air is purged from the system. That should address your primary concern. If you choose to use a high boiling point fluid, be aware that many of them are more hygroscopic than OEM fluids and have reduced wet boiling point. That means that you will need to change it more frequently than OEM fluid.

Cross-drilled and slotted rotors may reduce your braking power since the swept area of the rotor is reduced as compared with the OEM design.

OEM pads are excellent for the street, but under hard, repeated braking will exhibit fade, just as reported by brunodkid99. The HPS pad tolerates heat better than the OEM pad, so that is not likely the issue.

 

Is there a thread on how to change the break fluid? can someone redirect me to it?
thanks

 

This is a pretty basic service.

Here's a generic link that works equally well for S2000s and F250s - http://www.advanceautoparts.com/english/yo...r20011001bb.asp

 

I was at Mid Ohio this weekend and the car had slightly used Hawk HP Plus pads and ATE Superblue. Brake felt linear and felt very slight fade throughout entire day.

 

I use axxis ultimate for the street(pretty quiet, easy on rotor and pretty cheap)

i flush my brake every year, bleed every time before hitting the track.

if you are doing much aggressive driving, go with DOT4 fluid instead.

i use valvoline synpower, which is cheap and easy to find. the only complaint is the colour of the fluid
