Brake Flushing- Slow Going

[slowflyin]

Recently my left brake was slow to release.  It happened a couple of times.  A quick search of MS revealed others had experienced the same problem and that flushing the system solved it.   Armed with this newfound knowledge, I hooked up my trusty pressure pot and began.  At first, there was barely a drip.  I'm thinking I've found the problem.  It must be gummy, thick fluid.  I persisted until finally a very slow, very small, but steady stream began to flow.   I'm thinking, this is working.  I sat in anticipation waiting for something nasty to emerge.  Here's the rub.  After approximately 30 oz of fluid (two water bottles) the stream never accelerates to what I'm accustomed to when bleeding brakes.  IAW the MM is work the pedals, no change. Furthermore, the fluid looks great.   A repeat on the other side returns the same results.  Pedals are nice and firm and I'm yet to test taxi it.  

What have others experienced?  Is the Bravo system restricted to a low volume when bleeding the brakes?  If so, perfect, all is well.  If not, inspections are in order for sure.  I've got dual brakes without the shuttle valve.  

Thanks in advance!

saw about the same after resealing both calipers in December, had to go to about 20 psi on bleeder to get things moving, most important lesson learnt: had to take calipers off again, flip upside down so bleed valve is up to get the last air bubble out from behind the pistons, we were scratching our heads, Brian Kendrick came up with the solution

Having consistent issues with the brakes getting mushy and requiring a rebuild. Time to upgrade to three puck brakes?

The bleeder will crap up and restrict flow, also the tubing from the bleeder to the catch can will twist just enough to loosely close the bleeder. 5606 does get gummy and cause a caliper to release slowly but my experience is junk/corrosion between the O-ring and caliper body forces the o-ring tighter against the piston causing it drag or get cocked in the bore. One of the problems when bleeding from bottom to top is the reservoir catches all the junk that is flushed out. When I had a leaking master cylinder a while back I opted to rebuild both master cylinders and both calipers while I had it all open. I also flushed out the reservoir and brake lines with rubbing alcohol and compressed air. Took a little longer (8ish hrs) over 2 days cause I repainted the master cylinders and calipers.

Three puck? The early TLS (through serial number 27-0107) had single puck brakes.

Mooney makes a dual puck Retrofit kit (p/n 940067-501) for those airplanes.

If it is only dual, I'd be one puck short of a triple. I guess that will have to suffice.
