New brakes!

[cat007]

So you got them working ... How do you like them then? Surely you took the time to bed them in last night?

Yeah - all sorted! I didn't get a chance to go for a drive last night as we had an appointment - will do tonight though!

[Py7h0n]

Just remember to do the Bed In as per instructions .... Very important to let them cool till completely cold once your done too.

Ferrodo DS3000.
You won't be disappointed with the braking performance, although they do seem to wear out rather quickly. I have used 2mm of material in 150km race and 1200km road driving.

You call that fast wear?

I use rear brake pads in a race weekend,
1 x 20min Qualifying session, and 3 6 lap races and the rear pads are worn to the point they wont do another 20 min qualify session.

In saying that though, they are cheap crap pads, but do the job perfect.

I have used one of Mintex's cheap materials (1122 IIRC) and run from brand new to backing plate in one day at the track. bottom of the line road pads never last

As is weight reduction, of which I've done none (yet) so car probably weighs more than factory . Around 1100kg at a guess

1100kg? You lucky bugger! I'll be lucky to be under 1650 with me and gas!

Join the club my Supra with me and 1/2 a tank of gas is just under 1600 kg.Heavy car 20 plus high speed stops from 200 kph no brake ducting = heavy pad usage you just can't escape that.

I've done ~600-700km's around pukekohe and ~3000 road km's (almost all of which were thrashing down back roads) on my Mintex 1166's with zero issue. Pad wear is minimal, would estimate 10-15% gone? Twin pot AE101 GTZ brakes with 255x25mm rotors on an ~800kg starlet running Penrite sin fluid. Braking just after the 100m mark from 200 km/h odd, so not exactly taking it easy. My rears do not look bothered at all, would say they will last for a *long* time. I couldn't be happier with the quality and performance from Race Brakes, have had many people comment on the face ripping ferocity of this combo.

That all said, probably not much of a comparison because of the weight of the car. a Supra at double the weight is having to dissipate a LOT more energy at 200km/h into heat with a rotor mass not a huge amount larger. It would seem that ducting is a must with a larger car. Temperatures above the working range of the pad are of course going to tear it up.

Brake fade can not be blamed on pads alone, more often than not it's the fluid giving up. uprated fluid is a MUST if you're fitting some hardcore brake pads and expect them to continue to function well. Repco fluid is going to be gone after just a few laps..

Ah yeah - stopping ~800kg isn't really a fair comparison

Unfortunatly because of my master cylinder sucking up all my time, I've run out of time to sort out some ducting.

I guess I'll just have to be careful. I'm sure they'll work - but for how long

Oh here's a thought - is it work taking the stone sheld/gaurd off? That should get me a bit of extra air flow?

[2jayzgte]

Yep bin them you don't need those.

[cat007]

Yep bin them you don't need those.

At all, or just on the track?

Dammit I wish I had enough money and time to make some ducting!

Just duct tape one of these on there... "it'll be fine"

I'm currently investigating how to put two of these under the car

[cat007]

In all seriousness - does anyone know where I should go (central auckland preferred) to get some hose I can use for ducting?

[strx7]

Bunnings or Mitre 10 mega are a good place to look, or irrigation/farming supplies store

I don't think you need them at all are'nt they just there to keep the brake dust off the inside of the wheel.

[the fallen303]

always thought they have a small duct at the front of them to help pull air into the center of the disc to help with cooling? i'm gonna try and leave mine on, and pull the ducting into there.

If you're lucky enough to have the little black front lip - they have a duct on each side that actually points to the brake system (dam you dad with your NZ new, factory manual ma70 haha).

Are you talking about the dust deflectors (fitted on some cars) or the chip protectors.

Think cat007 is talking about the chip protectors - lining the guards.
Would keep them for road use otherwise you'll go over a gravel patch and chuck stones and crap up everywhere

nah I was talking about the dust deflectors that go around the disk - not the inner gaurd protector thing that covers the entire inner gaurd....

I took my stone shields off, no negative effects as far as I can tell. Mine didn't look as though they had any form of ducting at all. You can buy aluminium ducting from heaps of places, I bought some from corys electrical, it's just that stuff you use for bathroom fans/rangehoods. I bought 100mm stuff, but never used it, and FWIW I think that would be too big, anyway.

I wouldn't stress too much about doing that anyway, once you get out there you'll realise you want better tires and suspension way more than brake ducts, M1166 pads and proper fluid will be so much better than anything you've used before you won't care

However - I dont' have proper fluid, I only have dot 4 stuff - ran out of money after my dodgy master cylinder decided it would be a great idea to airrate 3 bottles of expensive fluid lol

Ah my bad
