Dude I love the paint scheme! Your car looks awesome... Check Vans Video, I dont think it takes much to hang these brakes, when I was carefully scraping the pistons I got quite a bit of varnish off them... Didnt seem like much at the time, BUT.. What a difference a tiny bit of Gunk made... I could feel confident to brake at 300Ft at 110mph... Going into turn one at WGI ... and the "code brown" moments went away going into the bus stop at 130.... Im in-between coats of paint on my new "Stacker" , so havent been online tonight much... Wife took the enclosed trailer for winter storage so now I have one too many 951s so I have to stack them on top of one another...

It's a video, the dye comes from McMaster Carr. You will have to put up with the video blogger expressing his justifiably irritated attitude. I was particularly enamored of "F**** the NTHSA". It defies logic and common sense we actually pay for and put up with this nonsense.
Thanks for finding that for me. I do have to admit, he was entertaining.

How did you remove the "varnish" from the puck bores? You mentioned "Gunk". This has become a really intormative and enjoyable forum discussion.

One warning with the Motive Bleeder, if you've owned it for a few years do yourself a favor and replace the plastic tubing.
Brake fluid degrades the plastic and it will eventually fail or split creating quite the mess.
I just wanted to amplify this; I had the clear line on my Motive let go (kink in the line weakened it) when I left it pressurized and unattended over night. I went out the next day and it had sprayed a couple liters of brake fluid all over the engine and both front quarter panels. I was able to get it off before it damaged the paint on the quarter panels, but I'm going to have to re-powdercoat my valve covers. Be afraid...

Good precautionary note. I have already purchased a small roll of tubing because my MF bleeder is a few years old. Thanks. Also, I just ordered some dye tracer from McMaster Carr along with 3 ltrs of ATE 200 for future flushes. I also have a pint of generic DOT 4 laying around for when I pull and rebuild the calipers. Yes, I'm keeping the car.

That is coming in pretty hard. Sorry to digress.. Did you ever run on the track back in the early 80's? That corner was always the most exciting spot on the track back then, and the slowest. Wish I had some pictures from back then so people could see how nasty that corner was in the old days. Turn 1 had no pavement outside the white line. There was no chicane on the back straight back then either so turn 5 was exciting to. Man that was a LONG time ago, I am getting old!

Found a picture from back then. Circa 1980. This is from Corner 2 looking back to Corner1.

I was VERY careful and used a VERY sharp razor blade, NEVER use it "forwards" where it could catch, just kind of Dragged it backwards, there will be a "buildup" on the back of the razor blade. This is the real trick.... The pistons are coated with some sort of teflon so one "Nick" and it is all over, go get another piston.. Dont be afraid, Vans Video on youtube explains it well.. As a matter of fact, let me help you out a bit further... Link---->..

Well Make no mistake There was one time when I lost the rear end going in too hard and had to go 4 wheels off..(I was able to catch it) . Dont think I would of experimented going in that hard if there was still Grass and Gravel Traps...LOL

I do not envy you.

I transplanted a stock ZF LSD into my stock AOR with the assistance of Dr. Dimi. It made all the difference!
