I dont know if this would work well at all for me. First i dont think i have any kinda guard for my rotor... i could be wrong but ive worked on my brakes alot and cant recall one. 2nd im afraind that hose would melt and id have to find something a little more heat resistant

the hard part about our rotors is that on the back-side we have an axle to deal with

it's doable... when my new pads get here i'll make a write up on the brake cooling setup and report feedback

I'm not a street racer, but a keen "track-day" runner and better brakes are worth more in a race that more power, i've never been one to throw bags of cash i don't have at a car that withh never make it back.

The car in question is my 1990 Citroen BX GTi 16v, as well as having 182bhp & a 0-60 (mph) of 6.4s it has arguably the best stock brake system i've ever encountered being fully powered, not just servo-assisted.

Add grooved & cross-drilled rotors all round and it's as good as it gets, pad choice depends on road or track use, although RedStuff pads are too soft either way and disintegrate.

But, like any car, take it on a track and repeatedly brake from 100+ mph to a hairpin bend and your brakes WILL heat up.

Buy bigger rotors? only if they fit inside your wheels, mine are 15" and my rotors 284mm (+calipers) so they don't go any bigger, bigger wheels just upset the handling and wear suspension parts faster.

Hell, my Nubira will smoke if I jam the brakes from 120mph, i know, i did it when i got it just to try it!

Hence me looking for cooling options, water cooling is far too expensive an option for many of us and i was just interested in the back-plate venting idea. Great if anyone has ideas?

Cheers, JayW

ok a bit off topic but i got to ask this: does this mean that the harder the pad's compound the better braking power you get?

in that case what are the benefits of softer compound pads? is it just cheaper and more sutable for road driving?

also how can you know how hard is your pad's compound? is their some kinda "pad compound ratings" like treadwear and traction ratings for tires?

softer pads are a lot like softer tires... they wear out faster, but the performance is better.

redstuff pads are NOT for highway driving because they have to warm up

they are racing pads

ok now i got the softer/harder pads concept... now how to know how soft is a pad compound? do i have to depend on how long the pads last compared to the OEM ones or is it written on the pads (or its package) a comparative number to use when comparing pads??

Yes there is something to know how soft the pads are... i just cant put my finger on it.

They rate them by friction level.

I usually take off brake dust shields in any off my car. Anyway, although they do work and keep the wheels clean, they prevent the brakes from receiving adequate cooling which causes the brakes to overheat which then leads to reduced braking performance. The rotors will look a lot nicer if you have big wheels as there is nothing behind.
