I'm going to replace all 4 brake hoses with new items (just need to replace one corner but thought I might as well do them all).

Any advice on the best sequence so as to minimise fluid loss and the bleeding afterwards?

The bleeding should be as per manual, but as you take them apart, be ready to straight away put the new hoses back on (more so for the back than the front, the front you can plug if you have the little rubber grommets).

Easiest and least messy way is to simply get them back together as fast as you can once you have removed the old hose. It's a pretty messy job, and brake fluid isn't my favourite chemical of choice once it dribbles up your sleeves.

Mike,
If you keep the MC topped up and are quick at swapping the hoses, you will find they will gravity bleed, particularly the fronts.
I just swapped a front caliper on Barney due to a leaking seal, it gravity bled in a couple of minutes- no pumping needed. :D

good stuff mike.
gravity feed like Kev has siad or you could also try cling rap under the cap to seel it and this should slow it down

Or buy a Gunson's Ezibleed from MS (UK) and pressure bleed the system. No pumping, just use your spare tyre to drive the air out of each bleed nipple. I use it on all my cars and it works fine - the latest Mini World magazine has a feature on it.

Just beware that within the selection of caps supplied in the kit, there is not one to fit the Aussie Mk2 single circuit big plastic type brake master cylinder.

I drilled a small hole in the top of a spare cap to fit the Ezibleed adaptor to and it solves the problem.

If you`d like to do them all with the minimum amount of fluid loss then -->

simply release one bleed nipple (it doesn`t matter which one) then put your foot on the brake pedal & push it to the floor,,, use a piece of broomstick or a section of pipe from your vacum cleaner handle (which is what i use:-) ) & stick it onto the pedal & jam it between the seat crossmember & the pedal to hold it to the floor while you`re doing the job... when done this way no fluid will pass through or leak out at all & you can happilly do all 4 hoses with barely one drop being lost after the initial press to the floor , which you can safely & easilly catch in a hose & bottle as you do it.

easy-peasy

Thanks guys- thats actualy what I was thinking (the holding the pedal down bit) but didn't realise you had to open a nipple first. I thought depress, then open the nipple - catch the squirt and leave the pedal down. I use a hammer jammed between the pedal and the steering wheel mounting bracket when bleeding on my own - its just the right lenght.

I'm restoring a 69 van at the moment (Pics soon), i put a couple of holesaw holes in the inner guards near the brake pipes, so changing hoses should be a lot easier 8)
