Brake Issue

[rong]

I have an 07 S2000. I am going through rear pads very quickly. I have tracked the car for several events and have used 2 sets of rear and only set of fronts. Is there a bias control on this car that can be adjusted or can anyone give me some suggestions as to what the problem is.

Thanks in advance, Ron

VSA and OEM pad are your issue on the track.

1. Turn VSA OFF
2. Buy deticated track pad and swap them in when you get to the track.

I don't doubt that what Stratocaster said is correct about the VSA. That will probably help. I have noticed that on every Honda I've owned, I go through rear pads at a rate of 1.5 to 2 sets for every set of front pads. I think Honda just makes the rear pads pretty small and they wear out more quickly.

If you're a beginner like me I left the VSA on. I saw the light blink so many times that I know my ass is save again by VSA. But I do have a track pads & brake ducts. Don't forget fresh brake fluid too!!!

I wore through rear pads about 2x as fast as front pads. I think it's pretty normal, especially if you're tracking the car.

My experience has been quite the opposite. Fronts wear 2-3x's faster than rears. Even now that I have ducted the fronts, the wear rate is still higher up front. Most of the track S2000's out here(Mid-Atlantic) would agree.

Thanks everyone for your comments. I have been running with the VSA on and have seen the light blinking. I did not give a thought to it as for the rear pads. I do know I will be looking at track pads also. It seems that there is a conflict on whether the front or rear pads wear first. Can anybody else give an opinion.

Thanks

Are you using street tires or R-compounds and how often do you track? At the track, I experienced heavier wear on the rears and on the street, it was more even. I still had way more left on the fronts when I replaced them all (I cracked a front pad and the rears were down to the backing plates).

Street driving (and even a few track days when I lived in Phx) on stagger and non-stagger setups (FK452 225/245, GS-D3 225/255, PS2 255/255, PA2 225/255), I've always found my front pads wear about 2x as fast as the rears.

Front pads wear way faster than rear.... for me.

A few guys I talked to at the track had rear brake wear that was heavier than the fronts. I also have wider-than-stock rear tires so I wonder if that contributed? It may have been a possible issue with trail braking as well?

For tires I am using Potenza RE01 with standard sizing.

I was using RA-1's until this year. Now I run Hoosiers. How often I track is irrelevent actually. How I track has potentially more to do with it. My S2000 has been a track-only car now for a couple of years.

When using the Toyos, I used Carbotech XP10/8 combo. With the Hoosiers, I use XP12/10's. All four calipers have been replaced at least once(I gave up rebuilding them). The only problem I'm having now is rotors cracking within a weekend, despite being ducted.

You definitely want the fronts doing most of the work. Weight transfer is to the front providing more potential tire grip there. The brakes are bigger in the front- let them do more work. You might want to check your e-brake, too.

Checked the E-Brake and made a small adjustment. Wondering if there is something else going on. Is there an easy way of figuring out if the front calipers are working properly with the correct pressure?

I was going though a set of brake pads every event until I switched to track pads.

Is there an easy way of figuring out if the front calipers are working properly with the correct pressure? I have no way to measure actual pressure, but if you're tracking the car, you should be re-greasing the slide pins on the calipers yearly. If they aren't sliding easily enough, they may not be able to freely return to their "home" position. I'm not a brake expert, but I have had to replace just about everything in the brake system just short of the actual hard lines.
