Hi, can anybody tell me which discs go with the austin princess 4 pot type calipers as used on the 450se's etc, I have bought some calipers got a spacer kit to make them take the 24 mm thick discs that i have from a granada estate 2.8 ghia, they are something like 262 mm diameter, i do not want to start fitting them only to find that the pads miss half the disc or something simillar, all my calculations say they should fit, but it is my everday car and i dont want to be off the road for too long if i have to order some more bits.
I can't confirm for 450SE's but on the SEACs they orginally used these:
Front Brake Disc AP 270mm Outer diameter x 28mm thickness
8 Bolt Bellhousing
P.C.D Diameter 139.9mm
Right-handed Part No. CP 4530/776 P
Left-handed Part No. CP 4530/777 P
Available from
AP Racing Ltd
I found they were special order and in the end replaced my SEAC front rotors, bells and callipers.
Good luck.

Now I've discovered this forum I also could do with advice for big brakes. I have a standard 1985 350i with the usual appalling brakes. Can anybody point me in the right direction for a DIY upgrade; any info online?. Reading previous forums the vented Granada discs are the way to go - is that a straightforward replacement, and with which calipers? The Granada ones or are the Princess ones as easy to install? The reason I ask is inexperience rather than ability.
Thanks for any advice,
Mark

See if you can nick Steve Heaths old brakes now he's replaced them?

The easy mod is fitting the vented disc and associated caliper with increased area pad from the big-engined MkII granada's. You won't need to change the master cylinder as the caliper pistons are the same diameter as previous. I exchanged my old stuff for the bigger kit a few years ago for new items cost about 180 quid which inc calipers and discs.
It all just bolt straight on with a little bit of modification to the shields, with braided hoses and a carbon metallic pad (EBC Greenstuff etc) the brakes are then pretty decent, to finish it off I made up some ducting to cool the inboard rears discs and a master cylinder brace to stop it moving about.

No chance. The Wilwoods are going on the shopping trolley along with a 300mm ish rotor. The Wedge discs are cracked again. I switch to EBCs that are supposed to be rotor friendly and I start cracking discs and wearing them out like nobody's business. The EBCs will not be going with the calipers to the Griff!

That's what we thought.......Steve Beck was after your Wilwoods too! Mind you, for some strange reason he didn't want the Wilwoods that have been binned from mine 
I must say though, you won't be dissapointed by the Billets and rotors etc that you are getting - the ones on mine (see, beat you to it)seem to be excellent. They will be tested in anger at Bedford on Saturday.
p.s - a bit greedy having both your cars at Tower View isn't it?

anyone know the size and part numbers of the original disks, mine are the non vented type and measure 265mm diameter and 12 mm thick, the manual says they should be 269mm diameter, i bought the vented version from the granada 2.8 i estate and they are 262mm diameter and 24 mm thick (vented) again they should be 269mm diameter, now comes the next problem, i have got some princess calipers and copied a spacer kit from "rally design" but made it 12 mm instead of the 8 mm one that they sell (for 20 mm thick disks)everything looks ok but the original princess disks are only 259mm diameter making the suggested 269mm vented disks 5mm a side too big. any help would be appreciated - also my 265mm disks fit perfectly with the standard granny caliper with only the normal very small lip alround.

The original 350 discs are 2.3 granada so they should be the same Ø as your vented onesbut just thinner. the difference in Ø could be down to manufacturing tolerance. Are they a pattern or original Ford part? Also providing the pad won't jam on anything as it wears and your're covering all it's area then does it really matter that the disc is slightly oversize? alternativly you could make some sort of bracket to shift the caliper out slightly.

Peter,
by all means although they charge 75 squid for the priv. Don't know how they justify it but there you go.
Hmmm, let me think about it.
OK I thought about it, that's too much, no doubt Tower View will find something better to do with that 75 quid. Hope you have a good time.

The size that is quoted in the TVR handbook of 269 mm diameter appears to be wrong, I have spoken to many dealers and specialists and the disks are actually 262mm diameter(girling-df1640 solid, df1639 vented)the problem is the princess type calipers are made for 270mm diameter disks(solid 12mm thick so a spacer is used.Ford and no one else for that matter list any disk of 269mm diameter that will fit on a wedge, the only disks that will fit ar AP Racing types as fitted to the 400's and they are billet disks with a bell like the type shayes quoted earlier, they are well over £100 quid each and you need to buy the bell. the easiest mod seems to be to go and buy some granada 2.8litre estate front disks, pads and calipers which should fit straight on, peninsula sell the disks (£65+vat each) and calipers(£60+vat each)or wedge automotive sell a complete kit that includes - brake fluid, front and rear braided hoses, front 262mm diameter vented/cross drilled/ grooved disks, some decent pads, and 2 calipers to suit (think thats everything)all for £445+vat. this would have been easier that doing what i did and reconditioning some princess calipers, making a spacer kit, buying some EBC greenstuff pads and some brembo disks (262 mm diameter to for the granada)and finding that the disks are way too small for the calipers - teach me for being stingy in the first place!
