mazfg Posted November 14, 2011 Share Posted November 14, 2011 Currently doing front suspension. I want to overhaul my front brake calipers and thought about taking them off the hoses. Does the piece of cling film over the master cylinder work well, as in keeping the fluid in the pipes, or will it start to leak out. Would I be better just removing the brake fluid, but then can I leave the system empty for a while, whilst I have both calipers off? I will again have to do the same when i do my rear suspension and check the wheel cylinders there too. So an easy method would be good as I will be having to use it twice. As part of the overhaul I have some new stainless steel hoses to fit too.Any pointers appreciated :o) Link to comment Share on other sites More sharing options...
Richard B Posted November 14, 2011 Share Posted November 14, 2011 I got some cheap mild steel female pipe unions. The ones for making your own brake pipes with a pipe flaring tools. I then used chemical metal to seal off the hole. When you take the calipers off you can use these to seal the hose. You still need to bleed the system subsequently, but saves getting air into the system and less damaging than those hose clamps. Link to comment Share on other sites More sharing options...
piman Posted November 14, 2011 Share Posted November 14, 2011 Hello Mazfg, yes the cling film or a piece of plastic sheet does help. I always plug the lines as well as Richard describes.Alec Link to comment Share on other sites More sharing options...
mazfg Posted November 14, 2011 Author Share Posted November 14, 2011 So basically I need to make up some blanking plugs...great idea. What are threads on these? Link to comment Share on other sites More sharing options...
Steve Cureton Posted November 14, 2011 Share Posted November 14, 2011 I don't think the cling film method alone will work because if you disconnect more than one device then that will allow air in and fluid out. Some people use hose clamps but I don't like them as I think they can damage the rubber. My preferred method is to drain the system as the fluid should be changed every two years anyway.

My reservation was that, the calipers are going to be off for at least a few weeks and wondered if it was ok to keep the hydraulic system empty over that time. Being Autumn time and somewhat damp is water likely to find it's way into the system and react with the left over brake fluid in the system? I'd try and plug everything up as much as possible but you know what the fluids like for drawing water to it! Link to comment Share on other sites More sharing options...
nang Posted November 14, 2011 Share Posted November 14, 2011 I'd keep the fluid in, as you say will keep the nasties out. you can replace it with new fluid when you have the bits back on. Plasic bag works ok for me 8)Tony. Link to comment Share on other sites More sharing options...
mazfg Posted November 14, 2011 Author Share Posted November 14, 2011 Gonna get a few 3/8 male n female unions, plug the other end up and fit either to hose end or copper pipe end. Cheers guys Link to comment Share on other sites More sharing options...
marktheherald Posted November 14, 2011 Share Posted November 14, 2011 I keep a pair of hose clamps and pinch off the flexy pipes when carrying out repairs. I use the Sealey ones. http://www.toolbox.co.uk/brake-hose-clamps-7558-0000 Link to comment Share on other sites More sharing options...
Gt6s Posted November 14, 2011 Share Posted November 14, 2011 No need fo any of that. Get a length of wood and jam down the brake pedal this will keep the fluid in the lines. Link to comment Share on other sites More sharing options...

Good idea short term though. thanks Link to comment Share on other sites More sharing options...
JohnD Posted November 14, 2011 Share Posted November 14, 2011 I make up short lengths of tubing, that fit tightly over the flared end of the brake tube. Each is doubled over, so that the tube kinks and blocks, then held in that position with a twist of wire. You can make these up on the bench, and have them in your pocket to jam either end onto the brake tube once it's disconnected. Permanent, or at least as long as you need to get your calipers reconditioned.John Link to comment Share on other sites More sharing options...
mazfg Posted November 14, 2011 Author Share Posted November 14, 2011 Bought these http://www.ebay.co.uk/itm/300453167829?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649then going to solder over the hole, should do the trick nicely Link to comment Share on other sites More sharing options...

mazfg Posted November 14, 2011 Author Share Posted November 14, 2011 Oh, they were intended to lightly screw into the copper pipe where the flexy hose goes. If only finger tight I'd hope it would work without damaging the flare? Failing that I'll get the female version for the flexy hose end. Link to comment Share on other sites More sharing options...
