My 101 Sprint 1600 had discs put on the front at some stage and I want to identify them to source pads etc. Can anyone help?

The discs are approx 26cm diameter, and the calliper is 17.5cm end to end. It has an embossed marking " 12 6". Thanks.

Danke gta778126, since my original post I'd narrowed it down to a 105 (ATE type calipers) but looks like the 1300-1600 and 1750-2000 calipers had different size pads, the 1750-2000 being wider. I'm thinking my calipers might be those wider ones although it's proving quite hard to tell from photos!

The 1300-1600 brake disc has about 260mm diameter, the 1750/2000 has 272mm diameter. A 2000 brake caliper has 175 mm end to end.
I think you have 2000 brake calipers and small discs.

Hello Silvertop
Can you post picture of the rear? How was the 105 brake attached to the hub? Did the car originally come with drums or with Dunlop disks.
Thx

Thanks Rafael. I suspect the car originally had drums. It was converted to the current discs in 2002 when some other performance upgrades were done. The 2002 invoice didn't specify which discs and calipers were used and just included an item for "disc conversion brackets". They may of course have been from OKP.

Here's the back of the caliper. From photos of the 'wide pad' ATE caliper as fitted to the 1750 and 2000, I suspect it is one of those, but with 1300-1600 discs as suggested by @gta776126 based on the disc size.

The 1300 - 1600 and 1750 - 2000 ATE Calipers can be identified by the the spacing of the mounting holes, 3" on 1300 - 1600 and 3.5" on 1750 - 2000.

INTERESTING, if i'm looking at the photo correctly the caliper is on the rear of the disk whereas the 105's have them on the front. do you have a photo of the mounting bracket?

Thanks @super1750, they are 3.5 inches apart so that confirms they will be the 1750-1200 version as suspected. Very useful to know, many thanks. Next question will be which pads to choose (for mixed surface rallying)!

@ITALCAROZ, yes they are mounted on the rear (trailing) side of the discs. I had tried to get a picture of the back to show the mounting bracket but couldn't get the camera/phone back far enough to get a proper picture from that angle. I will try again when I am up in the garage later.
