MOTIVE Brake & Clutch Bleeding System

Marco wrote: The Fiero has a plastic reservoir, correct?   No fix necessary to the 1105 - it's nearly impossible to get it to seal on a plastic reservoir- you just need to buy the correct part.   The issue with the plastic reservoir is reason we made the 1115.  We offer a $15 upgrade to the 1115 for those that have the 1105.

I'm curious how the metal 1115 offers an improvement over the 1105 in regards to sealing on a plastic reservoir. Does it have a softer rubber seal as well? If not, I'd be a little dubious of any substantial improvement in sealing ability.

In talking with Brian, who in turn is in contact with Marco (the fella at Motive), it appears that the rubber seal may indeed be a little softer on the metal 1115 as opposed to the plastic 1105. Let's hope that's indeed the case.

So, did I notice any difference after bleeding the brakes with Brian's bleeder?

Yes!

As soon as I stepped on the brake pedal I could feel a bit more firmness. Obviously there must've been some air trapped in the system previously. The biggest advantage of using the groovy blue brake fluid is that it's so easy to tell when all the old fluid it outta there.

At the autocross on Sunday, the brakes felt really good. No pulling, no lockups, no fading (although to be honest we probably weren't on the course long enough each run to get the brakes overly hot).

I'm looking forward to trying Brian's bleeder on the clutch hydraulic system next and seeing if that makes a positive difference as well.

Brian, great news! Thank-you very much for your efforts in acquiring the pressure bleeder and correct adapters.

For sure! I'll just make sure this time that I'm not baking in the hot sun for hours IF there's another problem.

By the way Brian, I know you'll probably say "forget it", but with the kind of money the pressure bleeder and all the adapters are now costing you, I think everyone (including me) who wishes to use them should at least slip you a token few dollars for the privilege.

With the bleeder, could I flush the system with the alcohol as I would if it was fluid?...then add ATE?

Or do I have to flush with the airhose, etc. as last time...

Brian, I'm just curious... Why the possible need to flush out your clutch line/slave so thoroughly with air and/or alcohol? Was there a need to be this thorough with your brake line when you did it?

[EDIT] Hang on, I think I just realized the difference. You have DOT5 (which doesn't mix with ATE) in your clutch hydraulics but never had DOT5 in your brake hydraulics? Or am I still confused?
