So after my bike lying for 3-4 weeks, it appears it has not done the rear caliper any favours. The function has been greatly reduced, and the brake is sticking. I assume (?) That this means the caliper will need stripped and cleaned and rebuilt, which is fine, can anyone tell me how many seals I need to do this? I see wemoto selling them as singles, and they don't do a kit for the rear calipers.
I'm not interested in changing for a thou caliper, as I really want to keep it OEM (I plan on selling soon, so don't want the hassle of explaining that the rear caliper is different to someone who may not be a member from here).
Aside from giving the piston a good clean and changing the seals, is there anything else I should be looking at that may be affecting the performance? The fluid is only 4 month old, so I'm confident that's ok, although it may need bled again too?
If you're redoing the seals then it'll need new fluid and need bled again.
There are two pistons so you'll need two fluid seals and two dust seals to complete the job. If you split the caliper then there is a very small rubber seal between the two halves. Apparently no one makes a proper replacement for it but I just reused mine, as others have done, and it's been fine. It doesn't wear out like the ones at the pistons as there is nothing rubbing on it. Splitting the caliper makes it much easier to do the seals although I only did it so that it was easier to paint it.

It wouldn't be fun if it was easy, I just wish it wasn't this much fun.
Yeah, I know I'll need it off to do the seals, which will mean putting more new fluid in, I was simply hi lighting that the stuff in was new in case people thought to ask if the stuff in there had degraded.
So I need 4 seals then 2 dust seals, and 2 fluid seals. Magic, I'll get those ordered up as it's brutal not having any back brake :lol
If you don't think it needs the seals done then just push the pistons out a bit, not fully! and polish them, then push them back in, might solve it with a lot less hassle.

I suppose I could try that, but I suspect the calliper may be on its original seals, and polishing in that way is generally a temp fix. If I'm selling it I would rather do a pukka job on it. I'm a bit OCD that way :o
Me too but it might sort it. Try it first, save you money and a lot of time. I presume you have a decent metal polish. I used Gtechniq M1 on mine and they came up like new.

I've got polish coming out my ears at the minute, yes. Seems like I'm never done buying detailing kit to try out. Some britemax twins should work wonders 
Haha, tell me about it. Just spent a small fortune on some new bits and pieces: Megs Mf pads, Iron x, AF tough coat, oblitarate, triple. Really liking the AF stuff just now. Never used the britemax twins but heard and seen very good results.

Some of the AF range is excellent,James who owns it is a really nice fella as well. Tripple in particular is excellent

Yeah, been really impressed by their range. Only tried triple on a small area but it was very nice to use. Tough coat is working very well, beading like a demon, just not sure how long it'll last.

Depending on how much you use your bike, don't be surprised to still see beading after 3 months.
I've switched over to CarPro hydro 2 as my main sealant, not as durable as tough coat/cquartz uk, but it's quicker and easier to apply so I just do it more regularly as part of a wash routine.
Anyway, we have gone a bit geek, anymore of this and we will be outed on here I reckon :lol
I've got EXO on the bike. Put the tough coat on the car to try it out.
Main sealant is EXO but the tough coat I'll use when I do friends cars etc or my favourite wax, colli 915, so easy on easy off and so durable for a wax.
Hahaha, yeah. better start a detailing thread if we want to keep this chat going. haha
Sorry everyone...

A good old clean and application of red rubber grease might do the job, might save you the hassle of a rebuild.
So what does that involve then, cleaning it obviously, do you just put plenty round the pistons and on the back of the pads then?
