I saw a set of Tarox calipers today!

What a sight! They are the dogs ********

They are very light and can have 10 pistons!

The chap I spoke to says that 6 pistons would be

the most needed for a seven. The kits they do

come with discs (vented,grooved and cross drilled)

pads calipers hoses and all fittings needed.

Does anyone know the weight of the 4 pot calipers from

Caterham?

I am waiting for some prices but I dont think

they are going to be cheap.

Has anyone seen them or tried them on a seven or any

other car? (they do sets for anything from minis to

Ferraris)I should have some more info soon if

anyone is interested.

Details recorded when I fitted Caterham Big brake kit to the front of my car

 

22 Feb 1995

4 pot AP calliper weighs 1800gms

4pot mintex pads weigh 500gms

2 pot iron girling original calliper weighs 3200gms

2 pot pads and pins etc weigh 370gms

"2 pot" disk weighs 2.5kilo - 9.125" dia

4 pot disk weighs 3.560kilo - 10" dia

AP Disks: AP Racing part no CP3707-103P Vent Disc

O/S calliper CP 3876-112D

N/S calliper CP 3876-113D

 

I have heard good reports of James Whiting's 4 pot system which retains the original disks. If you look at the overall weights above you can see why. His point is that as a light car the Seven does not really need ventilated disks and retaining the parts you already have saves money. Furthermore replacement disks are very much cheaper and as I have already had to replace two disks at (£120.00 ish each if I remember) due to stress cracks that point is worth considering

I have seen them (pictures) fitted to and Escort Cosworth, they were on 340mm discs too! Looked very nice - but way OTT for a 7, they would lock up at the slightest touch I suspect. My AP 4 pots are bad enough as it is!

Simon, I am told the best way to judge a good brake or not is if you can get it to lock at 100 mph in the dry . A surprising number won't lock until they have pulled the car down to about 70, when its managed to overcome some of the energy stored in the rotation of the wheel and generated some heat . Not something I would recomend you test on the motorway though. My road car is dreadfull in this respect. You cannot get the ABS to kick in at anything over 40mph. I bet Peter C could probably add something interesting about the forces involved in this.
