Gt3 brake fade

[bridey0]

Whilst on the gas the other nite and having a proper go at my steels I noticed whilst applying a bit of heavy braking an heel and toe after 15 mins I got some fade/judder. I'm having them checked as a result. Sound wrong to u guys???

Unlikely I would have thought. 997GT3 with brake fade on the road, would struggle to get that on the track I guess. You sure it was not just the abs kicking in?.

They can be a bit groany when worked hard (the brakes that is) but I can't say I've experienced any fade, even on track, although in truth I never cane the brakes on track. I prefer to scrub off most of the required speed, then trail brake into the turn and blend the power back in at the apex (when it works)!

Ahhh didn't think of that it could well be.
Cars getting checked today so will see what feedback is. Also at what percentage of wear do an opc always replace brakes b4 selling approved used car??

Yep, it's almost certainly ABS.

It sounds like you're trying to drive the car through the braking prolonging the time they are applied, increasing brake temperatures and possibly warping the discs. Just be careful. I would be extremely surprised if you encountered brake fade in a GT3. I never have and that includes racing with standard brake set up.

Me too. Never had fade.

It takes some doing warping the discs on a GT3 on the road or the track for that matter. If you've managed it, you'd definately qualify for a driving muppet award. Although I'm told that most of these are won by drivers across the pond, I'm sure that our tiny island can produce the occasional winner.

Seriously though, I'd be stunned if they are warped. The 911 has no weight over the front wheels and at this time of the year where roads are greasy, it is quite common for them to trigger the abs as a result especially if it's a GT3 on cups.

could very possibly have been my ste heel and toe technique!

This.
A proper kicking in off the ABS under hard braking sometimes feels like braking on wet grass if not accelerating. As Steve said this happens quickly on Cups when greasy and/or when they are outside their optimum operating temperature.

ABS can be positively felt in the brake pedal (pulsating).

Brake fluid requires changing? Quite probably ABS aswell. I know when my brakes aren't properly warmed up, the ABS can trigger quite easily, especially on damp/uneven roads

[mrdemon]

I would just say change the brake fluid, too many people reading to much into this imo.

Ok tks

If youve managed to get brake fade on a GT3 then you sir, are a driving god....

Hi,

All day round Oulton Park and no fade for me either ?

sounds the most logical explanation....cheers

There was for me when I drove your car for a session though







...although that was due to an imbalance in braking set-up, not me trying to win Steve's muppet driver award

[Slippydiff]

I'd be amazed if they've warped, more likely to be an inconsistent transfer layer on the discs.

But it would also be worthwhile checking the inner faces of the front discs to make sure they're not polished iron oxide . . .

Come on Goose, come on here and tell them how you set my GT3 RS brakes on fire at the Oulton RS Day in March and even then not only did they not warp, but they worked and still do. !
