Quick brake caliper question

Hello all,

I need to get a full set of front brake caliper seals for my K6 bike. I have found several sets online, the cheapest being Wemoto, and my question is this...

Are the brake calipers on the K4/K5 models the same as on the K6 model? I suspect they are identical, but want to make sure before I splash out thirty odd quid on them.

Cheers,
Mike

ps, these are the ones I am considering - http://shop.wemoto.com/pictures.dyn?u=5835675qqq3087732

parts diagrams at alpha-sports shows all the same seals from K3 onwards except for bikes with ABS

Thanks mate, parts ordered. Hopefully these ones will survive my hamfisted repair techniques...

Why the hell would you need a new set of caliper seals on a K6?

thats true. unless you use it to ride along the beach to work through the waves the seals should still be perfect after two years.

Because I am a hamfisted buffoon, and shouldn't be entrusted with a child's plastic toolkit, let alone a new metal one ....

I was cleaning up the brakes and putting some of that red rubber grease stuff on the pistons. Only I manged to pop one of the pistons out of the caliper body, and fill the cavity full of gunge and cak, so to speak.

Now I am paranoid to say the least, so I thought it would be best to stick new seals in rather than risk having damaged one.

I then thought sod it, while I fix one, I may as well change them all and learn something while I'm at it

Whilst we are on the subject, if the seals appear undamaged, and I gave them a good clean, would there be any issues in reusing them. or would it be best just to buy new?

Cheers,

Mike

If they clean up and are undamaged then pop them back in and save your money. The dust seals can sometimes suffer damage during removal or can swell if the seal cavity has furred up over time. If they dont appear to be the proper shape and in good nick then go ahead and replace.

If you've already ordered a set you could keep them to one side until you need them or maybe sell them on here.

Make sure you clean out the seal cavities in the caliper body properly, I find a dremel with a nylon or brass wire brush attachment is good for this. It will also need a pretty good blow out with an airline or similar afterwards.

Cheers for that, I will try and reuse them, and see how it goes.

If you've left 'em out for any length of time you may find they have swollen and can't be reused 'cos they don't fit any more.

For future reference, if it happens again, you should just pop the piston back in straight away. That's really no different to putting a piston in onto a new seal!
