400/4 Brake Pivot Arm

Nurse Julie:
Hi Chaps.
Looks like I have a problem with the front end of my bike, its a bit unstable !!!. What I'm looking for is a good pivot arm and pin for my 400F but the 500/4 and 550/4 also fits I have been informed. Has anyone got one lurking in a dark corner somewhere please?.
Ta in advance

Problably got one somewhere Julie but it will almost certaily be in a worst state than yours. The pin corrodes in the alloy despite the 'O'  rings on the pin  and the alloy part hole enlarges. Does anyone know if someone bushes these or sells a slightly oversize pin so you can ream out the alloy. I did this on my 750K0 setup but it's a different design and slightly easier.

Phil Denton can make you one out of stainless steel, the pivot pin.

yeh, n sounds like the right thing to do.
Polish brake arm and alloy bracket, send to phil, pivot pin sent back perfect... probably all done for £70.
Paint brake arm if you wish but perfect job...
