| Subject: | Re: Kolb-List Digest: 6 Msgs - 01/29/14 |
I sold my original FS to a guy many yrs ago that was 90 lbs over gross. I'm not
sure is the wing will take it or not but your CG will be out too far forward.
To my knowledge, he never flew the Kolb.There's allot more knowledgeable people
on the list that can explain.

| Subject: | Brakes Not holding |
Im having problems with my brakes not holding on my MKIII Xtra with a 912 80ph
Rotax. They system is dual hydraulic Matco brakes. At first the calipers werent
extending and retracting and I noticed that they were gunned up so I cleaned
them with WD40, a green scrubby, and a tooth brush. Now they seem to be working,
at least the pistons move in and back out slightly as they self adjust. The
pads and disks dont appear to be warped and the pads still have a good amount
of wear on them. I have also bled them. As I didnt know any better at the time
I bled them in the same manner as car brakes. I have taken the wheel off and
removed the disk and made sure the pistons were working properly. There doesnt
seem to be any air in the lines.
Could I have gotten WD40 on the pads? I suppose that is possible.
They seem to work ok on the pre-purchase flight. The aircraft was trailered to
its current home.
Any suggestions would be most helpful.
Thanks in Advance,
Brad
