Hot brakes.

Have a look here too:

Unknown make (sounds like they just convert standard discs), but are a bit cheaper. If I stick with standard discs I'll probably try a pair of these.

Why bother with the drilleddiscs...it only makes them worse.....less heat capacity, more prone to cracking. Porsche uses them to some effect, but those are cast with the holes in them, which is a lot better than drilling perfectly good discs. I run slotted discs on my track 360, but it did really well on the regular plain discs as well (just wore those down due to worn out brakepads). Slotted helps prevent glazing of the pads, but good pads wont glaze over that fast anyway, so you might wonder if the rapidly increased wear on your brakepads is something your ok with.

BTW, I wonder if spacers can be made for the girlings as well.. they are split down the middle, but I havent seen that kind of modification on these calipers before.

For those that might be interestedin 240 calipers: I found some on ebay for about 80 dollars (incl shipping from the US...by boat). They are professionally remanufactured calipers, completely loaded with pads and shims etc.
We'll have to find some disc that will work with them though.

and drilled and grooved make your pads last less

From what years are the 340's that have twin pot calipers.

Some time ago I have tried to fit front disks from a 440 Turbo, but with no success.

Still got all the pieces.

I can't help thinking something is wrong if your brakes are getting that hot with road use...unless you're driving down a mountain on the way home

Both of my 300s have pretty good brakes, and the closest I've got to cooking them was following a 20 minute thrash over the cat and fiddle (twisting moorland pass) in the 360 doing constant 20-60(+)-20 pulls...and they were just starting to feel a bit weaker than usual by the end of it. Unless you're in that sort of territory, I suggest a hearty bout of 'stage zero' before you look at an upgrade.

cheers

I'm totaly with James on this. 300 brakes are quite good for road use.

The problem with fitting 240 calipers is the disk would need to move back about 20mm for it to alighn up.

8ks of downhill with about 40 corners at a pace most people would frown upon.

Can't space the calipers out Dai?

It can be done... somehow, on stock calipers. Cheers for the heads up on the PCD front Adam, the plan I had doesn't look like it will work then

Is your car in the photos?

If that are stock calipers... just need to find a refference in that discs!

Post by **Chris_C** » 11 Dec 2006 05:15 pm

Yeah, that was one one my cars, problem is I had to scrap it a while ago, and didn't have time to get the disc's off of it before it went. The calipers are stock, I took one off and offered it up against my 1.4's, they were the same.

Intresting thing Steve pointed out, is the 340 style ARB... thats a very very late 360GLT.

Post by **foggyjames** » 11 Dec 2006 07:59 pm

Dalahare - Yeah, that might well do it

Chris - I think it had early struts swapped on at some point - later 360s had the 'to strut' ARB mounting....earlier ones had the 'to wishbone' 340 type. Oh, and muppet for not pulling the discs

cheers

Chris - proper muppet

The problem with the 240 calipers are to get the centred on the disc the are in line with the mounting lugs. If you are fitting a much bigger dia disc you could make an adaptor to kcik it out further away from the hub centre.

Would these be suitable for stock caliper?

Perhaps one of the brake experts can advise

I have had the brakes of a 340 on fire on a single-track road here (3 stops from about 100 in a few minutes).

The back plates have already been mentioned. Some pr1cks have those brake dust guards: DONT DO IT. Regarding wheels, in my opinion, even the steel wheels vent well enough. Getting the air to them and keeping the brakes working at high temperatures is where you can make a difference. High temperature pads and air hoses from the front valence.

Make absolutely certain your rear brakes are in top condition so that they do some of the work!

If I remeber correctly the twin pot 340 caliper is fixed - 1 piston each side. If that is the case the twin pot gives no more clamping force than a single pistion sliding caliper of the same piston size.
