I've removed all 3 calipers for cleaning as I rebuild my SV - I drained the system when I took them off, but is it ok to leave the hoses open to the air for a couple of days while I service the blocks / pistons?

The hoses are braided with stainless banjos.

Also, Haynes manual says replace the copper washers, can I reuse them cause they look fairly clean, or are they a 1-use only affair?

Ok, Robinsons jobbie? They seemed to be copper rather than steel?

They are copper so they can compress. You can get them from many places.....

the ammount of times ive reused the washers without any problem, just make sure you have them on the right side of the banjos they came from as they were deformed to the cut of the banjo.

Yeah fine to leave them open, just don't leave the reservoir open to get full of rainwater, spiders and gravel.

You can usually reuse the copper washers.

Jambos advice of just leaving the nipple open - don't need to bother about the lever :thumbsup:

The reason they say you should use new copper washers, is because you've compressed them when they were tightend. It sort of work hardens them.

To get them back to pre used state, you need to heat them up with a blow torch or on a gas hob (don't tell the wife) until they are cherry red, then dunk them straight into water.

Then they'll be back to their nice soft state and give a good seal when you tighten them. Done this loads of times with my cars copper washer on the drain plug. Never had any issues with leaks.

Useful to know if you live miles away from a dealer or motor accessory shop.
