Shimano M666 SLX bleed ?

bragawd

Hi all...
think I need to bleed my rear brake.
Just put new pads in recently and now the rear pulls all the way to the bar only just stopping me.
I've bought the shimano DISCC BRAKE MINERAL OIL BLEED KIT
so what do I have to do ?

what makes you think you need to bleed them?

just pull the lever untill you have reset the pistons.

Tried that matey... even had 2 proper rides with them like this with many pulls.. they still only just stop me and lever can almor touch the bar.

sounds silly, but is the reach adjust too far in?

No pete its not that.. I have NO brake for like the first inch of pull.. and its not to much resistance as I pull to the bar

hmm it should properly bite round about 20-25mm compressed. this not the case? the normal reasons for bleeding is if theres air in the system - and the reuslt of air in the system is usually a spongey lever. If it pulls all the way back it may be missing a heck of a lot of fluid, or there may be a problem with brake itself

I'd say seeing as you already have a bleed kit, go ahead and try. If it doesnt work, you know the problem lays somewhere else!
