Brake Bleed nipple/Mityvac/Brake Fluid query

[Sid Squid]

If the fluid up the threads bothers you and you haven't got any Plumbers Tape For Everything, take the nipple out and coat the threads with grease, (the thicker the better), this will only have a temporary effect but it's plenty long enough to bleed the brakes.

I've seen someone shake a bottle of brake fluid before they went to use it before

Or for the correct term Polytetraflouroethylene tape

Do you think Red Rubber Grease would be suitable? I'm thinking it'd be good as it ought not to contaminate the brake fluid, should any find its way down the thread into the caliper. I'll try and get some PTFE before I tackle the rear caliper in 2 weekends' time.

you can get the tape from most diy shops, B&Q for example. Look in the plumbing and/or gas section.

RRG is fine, doesn't do any harm if a little bit gets into the fluid, not that any will if you use it on the threads.

You end up with little bits of it getting into the fluid when you use it on the seals and pistons anyway.

If it bothers you, use the bike for a week (the reservoir will probably look pink!) then change the fluid.

I only use the mytivac If the system has been dry e.g. the calipers or the lines have been off. I use the mytivac to draw the fluid through to the nipple but get the air bubbles, at this point I know that the fluid has come through to the caliper.

At this point I then change to the old pipe-into-a-bottle-that-has-some-fluid-in-the-bottom trick. Works everytime whether on the bike or on the car and works quick too
