Hi!

The Big Red casting numbers I have written down are 20.5249.00 and 20.5248.
Measure down the pad guide from top to bottom. Should be @ 72mm for the Big Red as it uses a deeper pad than the RS2/993 caliper.

Looks like the "small reds" = RS2 std calipers.
Take the pad end plates out and remove any oxidation underneath and reinstall. Check the piston dirt seals. That's it.

[kingos2]

the piston dirt seals are bubbleing and one of the brake hoses at the back is bent anyone no were i can get new ones, also what paint do you use on referb, the biggest piston is 72mm top to bottom sorry guy's but im confused,

the caliper measurements are-
length=800mm
width=600mm
bracket length=190mm

if this helps. anyone

That is the same number cast into the new standard RS2 calipers I have.
Audi part numbers 8A0 615 106E / 105E

Double checked and it may be 20.4565.00 and 20.4564.00 on the opposite hand.

ok finally got these fitted,parts used-
1-rs2 little reds (confirmed they are by audi)
2-rs2 brackets and bolt's
3-ferrodo pads
4-a8 314x30mm disc
5-golf gti braided hoses
6-7mm shimmes on caliper bolts to give space for the massive disc's

right then the calipers were very close to the wheels (i have 17in et 35) so i put 5mm spacer's and extented wheel bolts by 5mm on now i get wheel wobble at speed and sqeeky noise when on half or full lock left to right and sqeeeeling when braking at slow speeds, just woundered if any one new what might be causing this thank you. big thanks to the info from people for helping with this upgrade

Look very nice, where are the discs from and how much? Think i might be going 340mm route :mischeif:

[kingos2]

brakes were from www.needforspeed.co.uk about 220 quid with vat a p&p

and your pads are only sweeping 75% of the disc face.
