fitting caliper bracket

[MIKE550/4]

ewan

exactly that it does not go up and down but does rotate, and no  o rings

so will strip, grease get correct o ring and rebuild and report back, the main problem, this should fix then

I have taken note about spring washers to be added and the bottom collar to be turned and spring washers to be added

thanks guys

least I know what direction to take,  first port of call is this pivot pin

[Ewan 500 K1]

I fitted a grease nipple on the rear of the arm just so I could get some grease in there without stripping it.

thats a great idea

Easy to do Ewan so long as you position it correctly.

First the pivot pin has a small area on it which sits lower than the rest, it's right in the middle so that's where you need to position the nipple. The downside is that the surface on the outside of the arm is round, I filed down a small area so it was flat, used a right angled nipple off a 250N swinging arm IIRC, drilled a small hole and tapped it to suit the nipple thread, a small washer to help seal the hole between the nipple and arm and job was done. Worked great, a quick squeeze on the grease gun and grease was pouring out of both top and bottom of the pivot pin.
I fitted one on the rear brake arm pivot as well plus I fitted a central one on the 500s swinging arm, I never liked the 2 fitted on the outside so I drilled a hole, welded a 6mm nut onto the arm and used that to mount the right angled nipple, I then had the swinging arm chromed. I much prefer this method of getting grease onto the pivot bolt, I still use the 2 outer ones to grease the bushes and the central one to grease the outer surface of the bolt.

cheers Ken , I'm on it ... just ordered a couple of M6 grease nipples. I guess that you orientated the nipples so that they point to the outside of the bike ? This has got to be front brake tip of the year

hi

managed to get the pivot pin  out today, pin is now free, 2 orings in a recess at each end and greased and put back


hopefully now it should line up better,  the gap at bottom has now gone as in previous pic,will post up new pics later in week

thanks for all the help

so pivot pin regreased, spring washers attached to bottom mudguard and end of forks

for the bolt that holds on the caliper bracket and mudguard only room for flat washer and nut

it all seems to sit better so looks correct, also gapping on collar looks correct

comments welcome and promise I am taking it onboard
