nelsonian101 Donating Members 961 Member For: 16y 7m 9d Gender: Male Location: Sydney Posted 20/04/12 02:24 AM Share Posted 20/04/12 02:24 AM I am using 4 pot Brembos for around 5 laps before they get quite hot. AP Racing Dot 5.1 fluid, always fresh.Using the DBA5000 T3 slotted rotors and Endless PC35 pads.The dust seals burnt out long ago.Saw this pic on a forum somewhere and was wondering if it was that effective?I am already doing a cool down lap or 2 (plus a 100km/h road trip) when at Wakefield.Also using a floor/industrial fan when in the pits that I switch between blowing onto the intercooler/radiator and front wheels.6 pot AP Calipers would be nice but can't justify the expense of even 6 pot Brembos now.Any other ideas?

It will allow air to flow in behind the wheel and will keep your brakes cool. The part to remove is circled in red below. Link to comment Share on other sites More sharing options...
Tim Member 142 Member For: 16y 6m 22d Posted 10/06/12 10:46 PM Share Posted 10/06/12 10:46 PM What about water cooling them. V8 supercars use a mist of water into the air duct for the brakes. The super trucks that I saw racing a few years ago had massive plumes of steam coming off the front wheels. These trucks had a top speed of 180km/h and must have weighed 5 tonnes or more.

It looks like it's not available on imageshack.Thanks,Anthony Link to comment Share on other sites More sharing options...

knowhereman Donating Members 107 Member For: 13y 4m 7d Gender: Male Location: Torquay, Vic Posted 26/07/12 10:49 PM Share Posted 26/07/12 10:49 PM What Scatterbrain said, However!! Only cut slots on the flaps, dont remove the flaps completely. They introduce a high pressure area under the front bumper, that helps airflow into the the lower front grill. Also they will allow better airflow thru the slots you cut. Early BA's had the slots in the undertray for brake cooling, but were closed up early in the brake shudder saga. The theory was that dust and debrit were contaiminating the brakes causing shudder. That was the first reaction as the problem wasn't fully understood and it was a very cheap tooling mod with no piece price impact. Link to comment Share on other sites More sharing options...
