I've got a 245 GL, manual with vented front discs and I'm trying to determine what kind of callipers they are and discs that fit - it appears there were two different kinds - can anybody point me in the right direction?
As far as I know the Girling ones have an imprinted "G" on the outside of the calliper about the size of a 5c piece, while the others have nothing.
Do 1980 240s come standard with vented brakes, or have these been added?
I don't know - I'm pretty sure they were standard but that is what I'm trying to confirm - one of them is binding a bit.
There are two disc part numbers listed for 240's with vented discs, and two caliper types (Girling and ATE), and consequently two part numbers for discs/pads/caliper rebuild kits.
However, in my experience (pretty extensive) I've only seen the Girling calipers here in Australia, with the 20.4mm min. thickness rotors.
If you have the Girling calipers, identified by a G cast into the caliper behind the outer bleeder, the pad number is DB549. The corresponding rotors should be DR383.
If you haven't already got a supplier in mind for the parts, send me a PM as I work for a brake supplier, or try DVS if you're looking for high performance options.
Vented discs/calipers were standard on different models at different times.
I think GL's pretty much always had vented, except perhaps the first couple of years, up to about '77.
DL models mostly had solid.
For some unknown reason, GL's in '85 usually had solid, even though GL's from all other years had vented.
