Brakes, tell me something Options

[Trekkor]

Sure, this is a re-run.

I ran the track and got brake fade 3/4 of way into each session.

I just want to upgrade the pads and fluid right now.

What do you recommend/are using.
Wear is not a factor. I want the best stopping power for the stock FOUR calipers/rotors.

Do I need to replace the M/C with a bigger unit and what are your feelings on the prop valve vs "tee" arguement.

Also considering the SS brake lines.

Thanks and thanks to Mark for helping with the brake bleeding on track day.

I would recommend the Porterfield street compound brake pads, not the Porterfield race compound.... Motul is probably better, Vegas Racer's experience notwithstanding. I know more people who have had fewer problems with the Motul than with the ATE fluids. If you still had a -4, I would suggest an adjustable proportioning valve over a tee.

i just came from the Porterfield site and after i *eventually* found the car model in question (hint - they only have a few years listed for any given model...) i discovered that they actually have 4 compounds. we can eliminate the Race and Endurance Race compounds, but in addition to their street compound they have what they call a "Vintage Race" compound that sounds like it'd be pretty decent for AX and DE. i'm thinking very seriously about giving that a try at the 911's first big track day, which may be Watkin's Glen this October. i'll probably have sets of Race and Street available - just in case...

one of the aspects of the very high dry boiling temp fluids is that they are even more hygroscopic than street fluids - so it REALLY needs to be kept fresh. as in change right before a track event, rather than right after. Earl's also has a pair of very high boiling point )wet and dry) fluids, but since i don't have as convenient sources for those, i don't plan to try them any time soon.

i DO like the Valvoline SynPower fluid.

on proportioners, i almost think our cars have it backward... especially if we can learn to avoid panic braking and carrying Way Too Much stuff in the front and nothing in the back, the balance seems to be pretty good - at least that was my experience with the S calipers front and stock, widened calipers back, on my /6. if they're well-balanced with the tee, for adjustment, we'd want to be able to limit braking to the *front* for cases like rain, where there is less weight transfer.

in theory, you could mount a pressure-relief valve type proportioner anywhere in the front system but i'm really leery of that.

ideally, we'd run dual MC brake systems with a balance bar; they're expensive tho...
