Size of tubing

[594rmm]

I want to bleed the brakes having replaced a wheel cylinder, what size tubing will fit ?

Same diameter as will fit on the old wheel cylinder bleed nipple (the one you have just removed?), I expect. I rarely ever use one. Wash off after doing the job, if necessary. I don’t re-use brake fluid, so don’t collect it!

If you use some tubing with a 4mm bore it should be a tight fit. Feed it into a glass jar when bleeding; you can see when the fluid is free from bubbles. Doing this keeps things tidy. Apologies if you know all this. As mentioned, best not reuse old fluid.

Yeah, but it's not the sort of thing you want to spread all over the floor. far better to collect it and dispose of it correctly.
I admit the local Tip (aka Recycling Centre) won't have a brake fluid disposal tank, but I just mix it in with the old engine oil; in the great scheme of things it's minimal contamination compared to all the other things that are in old engine oil.
