Is a brake-flush a DIY, or is it tricky?

Hi all,
Yesterday I found my brake pedal being inconsistent in how far down
I had to press before I got resistance/braking. Do you think this is old
brake fluid, or something else? If I should get new brake fluid, should I
1 - Do it myself with tools I can get cheaply?
2 - It's easy enough that any decent car shop can do it well?
3 - Only take it to a Porsche expert?
thanks,
Joe

Joe....my 1st thought is .....'something else' unfortunately.....I'd let someone else speculate....I have a few thoughts.
As to your 1,2,3.
If the 'decent' shop has Porsche experience, going there would be OK.
You're talking ballpark $100......usually incorporate w/other service since it takes longer to get the car there than for them to do it.
Getting set-up to DIY is definately do-able. Trackers often DYI cause it gets done so often....often in ther middle of a track weekend.
Good luck on that.

Go over to www.cdoc.com and buy:
Bleeder bottle
Motiv Pressure Bleeder
2 quarts of ATE Gold
Start with the understanding that YOU DO NOT WANT TO LET THE MASTER RUN OUT OF FLUID... Otherwise, you'll get air in your ABS!!
I just flushed mine before the weekend of September 7th VIR event. Took me a couple hours to do it right, but I manually bled the system (Keep the bleeder tube submerged in fluid in the bleed bottle) ten pumps per bleed screw (2 per caliper) and topped the master cylinder between each caliper. I did each caliper 3 times in the rotation (Farthest caliper to nearest of the master RR/LR/RF/LF) and I was done. Once you're getting fresh fluid thru the sytem, attach the Motiv Brake Bleeder, Pressurize to about 14PSI with the system topped, and crack each bleeder (Outter bleeder first, then inner bleeder per caliper RR/LR/RF/LF) and watch the tube in the bleed bottler for air bubbles. When you don't see bubbles (Crack the bleed screw no more than 1/3-1/2 turn), the caliper is bled... Move to the next caliper in the series...
Being self sufficient will safe you bunches of cash, but do NOT do this if you're not familier with brake system maintenance!
