NC30 Rebuild #2


Recommended Posts

Oh dear I'm so slow. I've had a go at the brakes next, they were getting a bit crusty. Not so bad that anything was stuck though, which was nice.

Ahh lovely r£d bags of joy. Fresh nipples with their new rubber wear, posh little o rings on them. New pad pins all round too, why not. Also in shot is a bag of exhaust studs - I might get round to that next. Oh and an egg to oversee the operation. 081.jpg.80b2201b9c6a4edc891b5bedc9380bbc.jpg

 

Split, cleaned, and dried the calipers. Just used a toothbrush and a combination of Elbow Grease(tm) Degreaser and a can of WD40 knock off. Oh and gave the lips of the seals a good scraping with a dentist pick and a mini dremel brass wire wheel. They are always furring up, I think originally the calipers were anodised to stave off the ally corrosion but nowadays there isn't much left and they will corrode as soon as you stop looking at them.

Gave the pistons a rub wi' bit a brasso, just to get rid of the scum on them. Luckily they mostly all seem OK in terms of pitting, what little there is is up near the top where the dust seal would be, and no one cares about no dust (ok they do but they're crap anyway, and new pistons are ££££). Even so the pistons should be poking out enough that the pitting misses the dust seals anyway. The rear pistons are quite a bit worse, probably still fine though. £20 for new stainless pistons or ~£18 for OEM ones off Mr Silvers, hmmm (each).

Assembly next with a bit of hopeful red rubber grease to maybe please stop some corrosion (it won't) but it does at least mean you can assemble without getting DOT 4 all over the place. 

Still all quite boring. I might have a good crack at it this weekend though. This is the one. How far will I get? Will I open the garage door? Will I be too hungover? Will it be too wet? Too cold? I'm sure I'll come up with something.

Still boring, but I have at least got the rear brake back together.

 

New seals and pistons from Mr Silvers.

The next bit is vaguely more interesting. I need to repair the zorst, the bean tin repair had failed big time, with not much left to wrap another tin round. But I have got my trusty Aldi Arc Welder and some bits of stainless tube. Will it work? Will I just get distracted by pretty much anything and put it all back in the shed?... hmmm

What a setup. It really beats working on the floor though. Also see pile of practice on the floor. Good afternoon fun.

Aldi didn't have any stainless rods so I ebayed some.
