red spot on caliper

[haynes66]

anybody know the purpose of the red spot on the calipers of my 750f2?

I always thought it was a Q/C marker like the yellow blobs on bolts.
But I'm probably wrong wouldn't be the first time.

I wondered this too on my 400/4 I had the same thing, that was until I refurbished the calliper and painted over it.

But I did notice if you have original rubber hoses on your bike the ends of the hoses are colour coded and have either a red sleeve or a yellow sleeve at their opposite ends and I think it's just to identify which end of the hose connects to either the caliper or the splitter/brake light switch thingamybob.

At least that's my theory.

Regardless of why it was put there, for me it meant it had been on the bike since new and it was fooked so binned it and put a dss one on along with master cylinder.
