Cobbles and calipers

(1/3) > >>

Athame57:
I often ride on cobbled streets through having a GF in darkest Wapping. A few days ago I noticed the rattle from up front was more profound than ever and after sniffing about a bit I discover the plastic disc cover that sits behind the front brake calipers was loose, so I finger tightened until I got home and then fitted the shiny new stud & nut waiting for it anyway. Next trip on cobbles, ( & potholes ) was quieter but still rattley as ever, it appears to be the brake calipers as I seem to have eliminated everything else. Is this normal or am I missing something?

Fairly common when aged, you can put an O ring top and bottom of the swinging bracket on the pivot pin, not sure if they were there from new

Yes, they are meant to be there and I have mine in place, I recently serviced the thing, that's why it looks so shiny!  ;D

Only other thing i can think of is excess play between pin and bracket, would be unusual ask they are normaly siezed!

I'll check, but I doubt it. After all mine was actually siezed up just like you said. I think I did a thread on it even, a very nice polish mechanic heat treated the caliper in order to unsieze it for me, all for free!  ;D
