May sound an odd / stupid question but what can I use to block the brake lines off on the car?

I want to refurbish the callipers whilst the car is off the road but I don't want to drain the whole system and have a hard time bleeding it afterwards, nor risk brake fluid dripping on the wheels. so I want to take the callipers off, block the hoses off with something then once the callipers are refitted I will bleed/ refresh the whole lot.

Any ideas?

a few M10 female fittings with a bit of copper pipe flared on one end and crimped the other, or a pool of weld to block the hole up.

Could I use an M10 domed nut or are they not likely to seal properly and leak?

No, wrong thread and would leak anyway.

as above, most brake fittings are a 1.0mm pitch thread, standard M10 fasteners are 1.5mm pitch.

Presumably if you're using copper you could just solder up the end if you don't have a welder?

I've often wondered about this, but normally end up flushing the fluid at the same time anyway.

Why not use proper brake line clamps?

I'm pretty sure they are quite cheap and they are a handy tool to have.

My usual method is to use thin plastic foil (dunno If thats the correct name for it) over the brake reservoir to create a air tight seal. Then I unscrew the caliper catching the initial dripping, which is fairly mild, it will stop losing fluid after some few seconds. Then I do my work, reconnect the line, remove the foil and just open the bleed valve and let it drip for 15-20 mins while having a cold beer. Close bleed valve and I've allways had a stone hard pedal, even when I did the ones at the back and didnt even bother to load the compensator.
No pumping of brakes or silly equipment needed. Just open up valve and let her drip away :p

That would work but the callipers are more than likely going to be off the car for a month or so, I'd rather know they aren't going to leak brake fluid over the wheels/drive during that time so i'll get some blanks made up.

I do the clingfilm thing too.

TBH you'll have to do a damn good bleed anyway so it isn't too big a concern.

Dan,

If you can source a female to female joiner, should be an easy find at a motor factors or rally design if you struggle, then pm me your address details and I can mail over a couple of mail fittings that have been welded shut to put in the other end of the joiner....I only have a box of male fittings in the garage.
