Question on brake bleeding

[Bigdaddy]

Two questions.
I checked at my local auto parts store and found brake fluid marked DOT 3-4 hi-temp. Is this OK to use?
On bleeding the calipers, would it be better to push the pistons all the way in to ensure that all of the old fluid is removed?

You can also gravity bleed your brakes if you have time. See oemtech's website for the procedures.

The Ideal way would to have 3 people doing the procedure. #1 to KEEP the reservoir full.
#2. to pump the brake pedal untill resistance is felt then HOLD it while you (#3) open the bleeder valve on the wheel. The person pumping the pedal MUST keep pressure on the pedal even though it has gone to the floor until you turn off the bleeder valve and yell at them to start pumping again. This stops air from being sucked back into the system.
It is also recomended that you attach a clear plastic hose to the bleeder valve and insert it into some brake fluid in a bottle or jar. This again helps prevent any air from being sucked back into the system. It also alows you to see air bubles and the color of the old fluid as it is pumped out.
Hope this helps.
