Removing front brake calipers

[CheshireCat]

I need to remove both front brake calipers for over a week whilst they are serviced.

What is best way to stop the brake fluid running out and getting air in the system when removing the calipers and whilst they are off for a week ?

Put a few layers of clingfilm over the master cylinder filling point and screw the cap back on. Also tie the hoses in a vertical plane so the open end is as high as you can get it.

Don't let anyone push the brake pedal !!! A note on the dash as a reminder is the only way to minimise this happening.

I let them drain to an old pot and just left it with the MC reservoir cap left in place. I figured the whole system was going to get bled through anyway. Don’t know if this was correct, but did no harm for me.

You can also push a tight fitting round bit of softwood into the free ends of the open hose ... It will swell and help seal it. But ... you'll get air in there ... the calipers will come back full if it. Just bleed it through.

Golf tees can be used but you can also get blanking plugs that will screw onto the hose. The people doing the calipers May have these, if not you can find them on Amazon.  System will still need bleeding whatever you do.

Many thanks for all the replies.

I took the calipers off yesterday after putting a few layers of cling film on the master cylinder, rubber glove fingers over the brake pipes and a rod to keep the brake pedal down and no fluid has come out .
