brake and clutch flush this weekend - 986 Forum - The Community for Porsche Boxster & Cayman Owners

Sorry, I know this subject has been covered ad nauseum. I want to do a hydraulic flush this weekend. I've never done the boxster. It was last done 2/07 by the dealer I bought it from. I have a nice brake bleeder machine left over from my bimmer days that fits the boxster cap perfectly. My question is: I'm in a small town and we have the basic stores, autozone, oreillys etc. What fluid would you guys recommend that I could purchase at one of these stores??? And also, how much should I buy to do all four wheels and the clutch slave?? thanks in advance!! sean

2 liters of brake fluid and this is the stuff i used last time and loved it. Brake Fluid enjoy!

I think Porsche requires dot-4. ATE appears to be everyone's favorite for it's high boiling point. I actually found it at the best price at a local Honda dealer last year.

Thanks for the replies. I'm 90 miles from the nearest P-dealer. We do have a honda dealer though. I'm thinking of going with the blue stuff, as there is gold in there now. tnoice, do you think 2 ltrs is enough?? thanks sean

If you're experienced flushing brake fluid on the BMW then 2 liters should be enough. The first time I went a little overboard looking for bubbles and used every last drop of 3 liters. Changing fluid colors will certainly help you tell when enough is enough.

Yeah, the boxster looks pretty easy. I may not even have to remove the front wheels to get to the bleeder valves. The only thing bothering me is the clutch slave. It looks to be a nightmare to get to. I have to have someone or something holding the clutch pedal all the way in when I bleed/flush it too, right???

Either a second person or a length of wood positioned to depress the pedal.

It's tough to tighten and loosen the nut for the clutch. But it's do-able. Once you provide pressure to the reservoir and open the bleed valve, press in the clutch and it will stay down. You have to actually pull it back up when you finish bleeding.

... especially if you're changing colors. As soon as blue liquid starts coming out, that point is done. You should be able to do all 4 corners (2 nipples per caliper) and the clutch with one litre. Here are my instructions. http://www.pedrosgarage.com/Site_3/Bleed_the_Brakes_%26_Clutch.html Happy Boxstering, Pedro

[QUOTE=SeanZ4]I may not even have to remove the front wheels to get to the bleeder valves. QUOTE] Its better to just pull them off. Don't forget you have to do both the inside and outside valves.

lol. when i bled my brakes this past summer, i realized that when i read some of these posts that i forgot to bleed the inside of the caliper.

Thanks for all the replies.... I'm glad I came back and read this thread again. I wasn't sure if there were 2 nipples or not..... I'm having trouble finding the blue stuff in my area right now. (middle of KS) I may settle with a high quality dot 4 of some sort. I haven't checked the honda dealer yet. I've heard they may have it. Thanks for the instructions pedro. I'm going to go print them out now.. sean

First time doing a brake bleed I used about 1.5 liters of ATE blue. With more experience maybe I can do it with 1, like the pros. Shipping was expensive enough that I bought 4 liters and a couple other odds and ends to get free shipping at Pelican. It's good to have a little extra around.
