Guys (and girls if there are any on here),

As many of you are aware, the recommended brake fluid change interval for our cars is every year, more frequently if you go to the track. With that in mind, I found a link that details how to build an inexpensive pressure bleader. So, without further ado, here it is:

Note: This is on my to-do list in the near future, so there might be some slight difference in parts required for an E30, as this was done for an E36. Also, if anyone has already made something similar, post it up!

Well, I finally got arround to making this thing this weekend. I got a little sidetracked on my way down to Florida.

I actually wound up using a sprayer from Lowes, since there's not an Ace hardware near my new house. I would say it was even easier to put together than it looks. I hooked it up to my master cyllinder, and it held pressure, so it looks like I'll be good to go this weekend. The plan is to bleed, and install new pads and rotors. updates to follow.

Got 'R Done!!

A couple of lessons learned:

1) 20 psi is totally unnecessary. you could blead with ~5 or so psi. Just enough to push things out

2) this was really quick. Only took five minutes or so to do the actual bleading.

3) USE HOSE CLAMPS!! Unless, of course, you like the idea of a hose flying off, and presurized brake fluid spraying everywhere. Not that I have any experience with that.....

Anyway, the car is back on the road. Went with stock rotors, Axxis Ultimate pads, and Super Blue fluid. Seems to stop really well in limited driving after bedding the pads in, but it could just be placebo effect. At any rate, it was time, and I can take the brakes of the list
