Default Caliper Help

Good afternoon,

Wonder if someone could shed some light on my front calipers in terms of part numbers and compatible parts. I have a 1985 Audi 80 GL (1.8 Carb) and I believe its fitted with 4x100 239mm vented discs.

811 615 123
811 615 124

I can find many that say they fit the B3 cars, but not the B2. I have also read somewhere that the callipers are the same for both vented and sold discs, and its the calliper carriers that are different.

Are the callipers the same for vented and non-vented discs?
Are there any variances between B2 & B3 callipers?
Many sources seem to say its the Girling/Lucas 54 that I need, is this correct - I cannot see any numbers on my originals?

One of my callipers has started sticking and requires a rebuild, however for the cost it seems to make sense to simply swap them out and keep my originals as spares - that way I can rebuild them in my own time and gain the knowledge of how to do it in the future.

As always, any help greatly appreciated.

Brgds,



Simon
