I understand it's 8 seals per side but I'm not paying that plus labour so my question is I'm a resonanble home mechanic but have never tackled calipers so do you guys think if I get all the parts I could tackle this at the weekend?
If so any hints and tips or potential pitfulls to watch out for?
thanks in advance.

The seals (and pistonias if corroded) are expensive fur what they is, even aftermarket wans.
Ear is how I did moine: http://www.carpe-tdm...430&hl=calipots
Ewe wont need to split em though unless you really feel loike it.
I would def not put on all yer new kit until certain yer stickin calipot is fixified.

Doin valve clearances? Use dappers valve shim exchange program and the job will be carroty - Free (other than you postin me yer shims) for sporting members.

get my local bike shop in Chippenham to do the work for me and at the same time replace all of the caliper seals but the shop has quoted me £132 plus vat for the seal set!
Not those saddo tossers on Bumpers Farm FFS! ( A Corsham boy speaks!)
I got best results removing disc bolts using soakage, an impact driver, a hammer and a little twistage back and forth whilst hitting them.
DON'T be tempted just to undo/leverage the bolts. That way lies snappage.

You don't say that the seals are leaking. If not then a good clean with brake cleaner and toothpicks should be sufficient then with the old pads in position, lever the pistons in to get sufficient clearance for the new pads and discs. If you haven't drained the fluid then make sure you don't overflow the reservoir when doing that. Make sure the mounting face of disc/wheel is clean because a spec of summat you didn't see can cause the disc to run out of true sufficient to feel pulsing at the lever.

Praps remove the calipers and pads and pump oot za pistons and inspect them before you pull zem to bits.
If ze pistons are corroded badly you can suss out options from there.
The seals can be reused usually if the pistons haven't chowed them up.
You need to clean the oxidation from oot ze grooves though.
They are not hard to split and you can get at the grooves much better.
You need a little heat on the disc bolts to soften the loctite;less it 'ill be a Lee Henty job.
The price of new seals is why blue spots get used as an upgrade; pity you already bought new pads for the 'riginals.

Many thanks for the advice and yes bumpers farm! You also in Corsham then ?

Yeah don't as yet if leaking so hopefully not but won't know till sat when i dismantle. Only reason i was thinking of replacing the seals was after purchasing new discs and pads and i haven't tackled this before so thought best to get it done until i was quoted that for the seals plus 2 hrs labour so ill tackle it myself.

If you do snap a bolt off, I'm about over the weekend, the carpe disc bolt drilling and hub thread recovery service could attend.
I have friends who live down there and his Bonneville needs a slight fettle anyway.
