Is this right? - Jbizzle - 27-08-16

Hi all,

I'm away on a touring trip at the moment, felt some vibration coming through the bike.

I have just adjusted the chain to the spec in the manual but it's seems to be slapping about a bit. What do you reckon to the video is this right???

Also I have cleaned up the front brakes as they were binding. Bled them properly afterwards but they still seem to be binding on the disks, any ideas why that might be??

Thanks all in advance, any suggestions welcome!

Cheers,

James

Hiya fella,


The chain slap in the video is perfectly normal when the rear wheel is off the ground. Its due to the wheel/chain being effectively unloaded or having no resistance to deal with - 100% guaranteed normal  :thumbup

When you say "cleaned up" the brakes how involved did you actually get?
The outer pistons might look okay but that doesn't mean you might not have any rust spots inside stopping them from functioning properly.

So I took the calliper off and pumped out the Pistons. One a bit too far and it popped out. (Fast forward dot4 pissing everywhere especially and all over my front tire  :'( )

Cleaned each piston with brake cleaner (lots of)  got rid of all the crap that built up around the seal. The a small smear of copper ease round the pistons before pushing them back in with the pad.

Cleaned up the pad and the calliper.  But of copper ease on the corners and back of pads.

The off on my merry way  Smile

Oh no  Confusedtop


Copper grease has metal particles in it, and shouldn't go anywhere near pistons AT ALL.
You need to get that totally off properly with brake cleaner and a good scrub.
It will damage the rubber seals and stop the pistons from sliding, as you're unfortunately finding out the hard way.


Pistons should be smeared with red rubber grease which you can buy in small pots or even sachets, and is kind to rubber seals and will protect the pistons.


I would do that sooner rather than later as well before you cause more problems.

Ok cheers Darrsi. Il get them cleaned up and lined with the proper stuff. if using the be right lubricant doesn't work any suggestions on what else can cause binding?

There's a small chance that the copper grease could be causing the rubber seals to swell, plus the copper granules in the grease will cause friction.
You seriously need to remove it as soon as you can.
Google 'copper grease brake pistons' and you'll understand where i'm coming from.
Chances are this alone is your issue.

Hi Darrsi,


All cleaned out and used the proper red rubber grease, voila, binding has stopped! Do you reckon I will have knackered the seals?


Thanks,


James

As long as you're braking is good, there's no leaking fluid, or any more binding, then it sounds like you've possibly got away with it.

Basically, if it ain't broke, don't fix it.  :thumbup

I'll normally clean my pistons up as late in the year as possible, before the weather turns, to get me through winter, then again when the warmer weather appears in early spring.
Works for me, and keeps them functioning well all year round.
I don't get any pleasure out of cleaning them in the freezing cold weather during winter, 'cos I like to take my time, so will always opt for a nice sunny day.  Confusedun
