The phrase: “NOT FIT FOR PURPOSE” hasn’t been used yet...............![]()
I agree that if they're leaking then they're not fit for purpose and should be replaced.
That said, mine haven't leaked (yet) and I find that they're great at anything less that 9/10 riding speed when they only just start to fade. That could just mean I need better pads though.
I think it's being blown out of proportion a little bit. Yes, some leak and they shouldn't, but they've all been sorted with no questions asked and (unless I've missed it) there's been zero reports of any actual braking failures with leaking calipers. So they're still doing the job before being replaced, albeit with some leakage.
far too much snowflakery going on in this post. Get them changed ffs stop fucking moaning, its under warranty. Well saidfar too much snowflakery going on in this post. Get them changed ffs stop fucking moaning, its under warranty.

A lot from people who don't even own the bikes with Hayes brakes, priceless. The fluid if they leak isn't pissing out, its a small drop and its being sorted. Even Brembo callipers have had issues, as posted earlier. I don't understand the god like admiration for Brembo. They are also a mass produced product. Personally I don't care who makes the components on the bike as long as they work. My brakes work fine and the callipers don't leak, but if they do, Mr BMW will sort for me, so all good![]()

or is it here here
im sure the spelling police will be along shortly to tell me im sub human for getting it wrong 







Now i would suggest that BMW moved to Hayes as they are cheaper and cut production costs and therefore increase their profits.
i get the feeling that the leaky calipers happen from almost new?
it would be interesting to get a feel for when they started leaking on the bikes that have actually have had issues?
Hopefully Brembos will be standard fit again soon, I will wait a while before upgrading to a 1250.

But why? If it was a new Brembo calliper fitted that was weeping, would that stop you buying until they put a different brand on?
Mine have leaked on two sets and the bike has done a total of 6 miles
