I have I have - gotten brake fade with stock brakes.....
In the Miata.... On Skyline dirive (on the peninsula). Which is really wierd because the Miata has vented disks. Kinda freaks me out. Same road with the 914 - no such luck. |

Funnily enough, my Alfa brake fade incident was also on Skyline, on the section between 92 and Alice's. 160hp, 2900lb Alfa w/ vented rotors all round = overheated brakes. 115hp, 2400lb Alfa with solid rotors all round = no overheating brakes. Vented rotors aren't magic. They'll overheat bad if there's not enough air to them and you stress them hard enough. |

As you have found out there are several things that can reduce the chances of brake fade from over heating. Clean, hi temp brake fluid, larger calipers which provide a larger heat sink for the fluid, vented rotors with some cooling air directed at them and short hard braking instead of easing onto the brakes. A couple of additional items are much longer brake lines in front so there is more fluid volume to absorb heat, a fluid recirculator with the lines going through a cool can type of setup and finally a water mister in the cooling ducts to help cool things off. We don't have much room for the recirc system but I have added 36 inch long sections of line for the front brakes when I switched to Volvo calipers and will have to wait until the first race in Tecate Mx to see if the fade problem has been licked. It was raining in Phoenix so it did not matter. The long brake lines is a trick used by the BMW 2002 vintage race guys as they have a lot of trouble with brake fade they told me and this cured it.

I did... but what does any of this have to do with my browser? (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif) I did, I did get a package today. I got a bunch of packages today: 22 caliper cores 24 rebuild kits 24 plugs 4 outer adjuster screws... ...and 2 beautiful number circles with the coolest, correct silouette that I've been aching for (cup circles with a teener at the bottom for those who are wondering). PM me the amount and PayPal address and I'll cash you out tonight. Has anyone seen Andy and his Big-ass brakes that stop on a dime? (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif) |
