Re: Brake bleeding
The approach I'd take is to do the calipers one at a time, bleeding the system after each. It's a little bit more time-consuming, but better than trying to bleed the whole system at once - you do at least know where the problem is!
Before you disconnect any of the hydraulics, take the cap off the fluid reservoir, cover the top of the reservoir with cling film or similar & then replace the cap. This will block off the air hole in the cap - if air can't get in, there's less likelihood of fluid running out.
Before taking a caliper off, clamp the flexible hose to stop fluid running out - as it appears you are replacing the hoses you'll have to take them off, but if you leave the old ones in place until you're ready to put everything back together you reduce the time the system is open to a minimum, so there's less time for fluid to run out. If you're not reusing the flexibles, any clamp will do; if you're reusing them, use a proper brake hose clamp - some people will recommend against clamping hoses, but I must say it's never caused me any problems......
As for bleeding, I use a Gunsons Eezibleed (yes, wrinx, I've had the seal problem!).
Where are we going & why am I in this handcart?
