Front brake line leak....hmmm help

If your having trouble bleeding them just open the nipple and leave it for a few hours, gravity bleeding is normaly pretty good.

Hey all, brakes lines on no worries, bleed them as usual was easy as due to Mortons sweet golf tee trick. I was wanting to service the piston as there was a hole in the boot seal and the brakes are a bit slow, even before I put the new lines on, I cleaned the two sliders and re-greased them and the boots were all good, a lot more movement in that. I think that the reason that they are slow/spongy is there is probably a build up of crud in the bore as when I bleed the lines there was a HUGE amount of black waste in there that I cleaned all the way through. nice and clean now. Is it ok to attempt to clean the piston if I never had before, its pretty simple I reckon, I ride DH bikes and its got to be the same process, just got to put the bore back in straight and slowly.

Yep, just use a scotch scourer, don't use emery or steel wool. If the piston is to be taken out, you should do the seals as well, that way you would also clean out the seal grooves.
Cheers, the ferret.

you can pull them apart, remove the seals & spray the entire unit in non-coustic oven cleaner & leave for a few hrs or overnight, using a scotchbrite scourer (usually a white scourer) & a toothbrush for the tight areas etc scrub it thoroughly & rinse in clean water, I sound like my wife lol

It is also a very good way to clean heavy brake dust build-up on alloys rims, works a treat
