Silly question time again

[southern andy]

Fitted my Dia Compe MX 900 last night, all works nicely but what the hell does the Weinmann semi automatic adjuster actually do ?

Is there an actual purpose for it.

turn it and see what happens!!!!!

It adjusts the gap on the caliper arms to the rims.

Cheers Mr Goose, i'm off to play and see it in action.

may not be a silly qestion .... ive had a few that dont serve their purpose .. , make sure the lil metal cog is sitting in the plastic slots ,remember  them "kitchen sinks" at DC are slinty eye`d bastardos

Pinch in the caliper with your fingers too at the brake pads while your turning it, if it's stiff the plastic isn't that sturdy and the metal teeth will damage it quite easily
