I did the clutch fluid change and it was pretty easy. I'm gonna go the brake fluid and read it's the same as the clutch.

So my question is when I unlock the nut and push the brake pedal, do i have to push the pedal down and then tighten the nut, let the brake pedal up, then un-tighten the nut, push the brake pedal, and tighten the nut while I have the pedal down.. or I could just pump the brake pedal and make sure that the resovoir is full?

Thanks in advance.

Technically yes, you need to close off the bleeder valve before letting the pedal come back up from the floor. I learned a little trick-of-the-trade from a track junky a few years ago and ot goes like this.......

-Attach a short length (12-18") of flexible tubing to the bleeder valve.
-Make a loop which goes from the vlave....upward...then looped back down to drain into a small bottle. The loop will keep fluid in the tube and not allow any air to get back-pulled into the bleeder.
-This will allow you to pump the pedal without getting in and out (without a helper, ofcourse).
-Check the reservoir after 10-15 pumps and top it off as you go.

I've done this dozens of times without a hitch. I've shared this a few times and it is a popular tip. Feel free to PM or reply here.

Both bleeds are pretty much the same technique. The only difference is that the brake pedal springs back up by itself so you must ensure that your "pusher" holds it down till you get the bleeder screw closed. The other obvious difference is that the brake bleed involves doing it 4 times and in a particular sequence.

Hockey,

I've tried the loop technique, and I didn't have good luck. It seems that when I lift the pedal, air is sucked around the bleeder screw into the fluid line.

I've observed bubbles enter the rubber tubing even when I closed off the valve.

I only crack open the valve a 1/4 turn. Any ideas?

Thanks!
I'll probaby try to do a DIY with pics since there is none....
hehe hopefully I do it right.

Just make sure you have a rock hard pedal and no leaks before you go out and possibly kill somebody. No offense.

Make sure your buddy in the driver's seat(or your, if you have really good buddies) doesn't slam on the brake, because if you apply too much force you can blew a seal.

Brakes are made to be "slammed" on. That's what they're there for. If you blow a seal "slamming" on the brakes while doing a fluid change, it was going to blow anyway. Better to blow it doing a fluid change than to do it while you are trying to stop for that kid who runs out into the street chasing his ball.

^ He might be referring to "not" taking the petal to the floor while the bleed screw is open. Not good for the seals.
