Brake bleeding
#12
Sometimes the lower pressure of a power bleeder leaves some bubbles. What I've done in the past is get about 15PSI on the power bleeder, crack open the bleeder screw, then cycle the brake pedal a couple of times. It worked really well on my Cayman, the procedure is in the shop manual. Haven't tried it on the S2K yet.

I use the Billman gravity bleed and don't necessarily get a hard pedal, but the brakes stop just as they always have. Is your braking performance bad?
Funny you said it took a while to gravity bleed. That seems to be the case for some people, others not. It never takes me more than 15 minutes per wheel, then again I don't sit and watch. I let it drip and do other chores.

Ditto- works great. Always have the same pedal feel/ consistent.

Have you seen one of these? http://www.brakebleeder.com/bleeding-brakes/ It may be the same technology as Red Sun posted above but it seems as though it should force all the air back out to the master cylinder. I have always had good luck with gravity bleed but it usually takes about 20-30 min per wheel for me. As for always getting air when bleeding I read in some caliper rebuild discussion that using a little of the grease on the bleeder screw helped seal it better so when you crack it open nothing sneaks by. Have not tried it yet so take it as internet info (use at your own risk)

But I do them in the complete opposite order. I start with the farthest one first RR, LR, RF, LF
I would have thought that was the bleed order as well - and is how I bleed the MGA. But I'm almost positive the shop manual gives the order starting LF, RF, RR and LR.
Maybe it doesn't make any real difference - as long as you get the air out!
How come your brake fluids are different colors? The only time I noticed a difference was between silicone (DOT-5) and glycol (DOT-3 or 4) fluids. But they are not compatible! I think I recently used an AP fluid (not sure which one). I think it was the same golden color as the regular DOT 3 or 4.
