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.

probably having 100% FRESH brake fluid in your car would have helped... (IMG:http://www.914world.com/bbs2/html/emoticons/spank.gif) that shit looked like coffee!!!

(lol, had to give you a chiding, trekkor!)

I probably should let Brad answer since he knows you and your car. But, I've never had brake fade yet, so I think you need a good flushing and use ATE racing fluid. That would be a good start.

Drew what brakes? Stock -6 brakes?

Trekkor... you've got a -6 in there now right? With stock -4 brakes?

Drew's right... ATE Blue and start over. Sounds to me like you may need different brakes and rotors.

Aren't 986 Monoblocks getting pretty cheap? Get a set of those with matching rotors and your troubles would be over.

paragon sells the whole 986 front brake conversion for 1k.

BTW he still needs 911 3.5" struts to utilize that, and a RJ or GPR rear monoblock mounts

I have A calipers in front with stock in the rear. I just pulled the rears off and am changing to 911 SC calipers and rotors. I will lose the hand brake but thats okay. I found that one of my rear calipers was missing the adjusting screw on one side. Don't know when or how that happened but it was probably contributing to my long pedal travel and slight modulation.

I have to agree with Eric, change to larger brakes and change out your fluid and M/C. A fast car is only as good as it's brakes.

I'm not smart enough to keep my mouth shut when I should.

I'm no expert, but I do have experience with brake problems. I am sure Brad-hole will be happy to point out where I am wrong. Here is what has worked for me.
1.) Upgrading to SS lines will help.
2.) A 19mm MC is a good thing.
3.) Dump the stock proportioning valve and put in a T.
4.) Super Blue fluid is the nuts. I have boiled Motul in the past.
5.) Always bleed the system before any track event.
6.) Heat is the enemy. Brake ducts for cooling help a lot.
7.) Street or 'sport' pads are no substitute for real Track Pads.

not neccesarily LARGER brakes, but VENTED brakes...

kinda limited with 4 lug. unless you buy mueller ™ hubs, and vented M calipers

see my previous post ...

vented brakes only work IF they get airflow. his airdam is sweeping the pebbles from the track, there is *no* airflow under his car, there's no way to get air through vented rotors with this setup.

trek, the solution is MUCH cheaper than all that was suggested above, simple *remove* the air-dam ...

A proper stock system with GREAT pads will work just fine.

John,

You nailed it. The next "greatest" thing is the unltra expensive Castrol brake fluid.

There is nothing wrong with the stock brakes. Trekkor fits in the same category as everyone else who has brake issues:

1.shitty fluid
2.shitty pads
3.worn stock components

All this adds up to a person who compounds the issue by hanging on the brake pedal because the car wont stop. Get GREAT pads. Replace the lines. Get a tee. Put a 19mm in.

Mueller did the drawings and test fit one of his Mazda calipers. It pretty much ended there.

John, you answered my question, nicely.

Nathan, I had that coming.
My plan was to have the whole system flushed before WCC, but, ( insert favorite excuse here ) ... (IMG:http://www.914world.com/bbs2/html/emoticons/dry.gif)

Anybody wanna tell me what brand of pad to use?

C'mon Brad, join in. I know we've had this discussion before and you've told me. Just making conversation. (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)
