I agree with the comments.  NEVER intentionally introduce air into a hydraulic system.  I use the attach hose and pump method.  I have the vacuum rig but it seems too slow.  Also if you have interlocked brakes (ie both front and rear actuate together) make sure you bleed all brake lines for each caliber.  For mine I have two lines to each caliber  :-\.

Never use old (previously opened) brake fluid.  The brake fluid is very hygroscopic and will absorb moisture from the air.

I would also suggest since you have all the equipment out; bleed and fill your clutch, if it is hydraulic.

I always suspected it was hygroscopic.  My bottle always points in the same direction.


I have lately been using the synthetic stuff, hoping it has a bit less of an affinity for water.

How do you dispose of brake fluid anyway?  I have been evaporating mine.

Local dump takes all toxic liquids from vehicles and recycles them.

Don't forget to lube up the rear suspension points (next weekends project). 

Some interesting reading (and if your just bored at least read the first table)

Thank you.  I saved myself the trouble of finding my grease gun and use yogurt instead.

So...if you get any on yourself, you can just lick it off?

I've used already opened fluid. If its NOT ginger ale color its not full of water! ;) I normally wouldn't but when the Motul I have went from a nice 7.99 for a small bottle plus shipping to $14.99 or so I just checked the color put it in and all was well! :D
