Bill,
I read your information on the parking brakes. It looks like it would be
a good set up. Is this unit available?The MICL (Michael) BRAKE system
that I am looking for, pressurizes the brake lines to hold the pads to
the rotors.
Larry,
The NAPA fuel line check valve is PN. WH 63X6 . It is 1/4 pipe on one
end and 3/8 compression on the other. This valve looks rather
restrictive but might be allright. The cost is $4.99. Might use more
than one???

The information is on Heinz Wittenbecker's site of his
installation. contact him at:

I would like to know also. I think that is the answer for a parking brake
for the GMC. May not be so good for long term but I would really like to
do it for a parking brake.

You can eliminate all the "plumbing" by going with a switch operated
solenoid valve. Leigh Harrison uses them in his 6-wheel disc brake system.

Mounting the solenoid at the master cylinder minimizes any brake line tubing
alterations.

For right now, go to: http://www.mico.com/blocks.php3.

I'll have to get back to you with the number on the one I have after I get
home from work. That is if I can find the box!

We run the J. C. Whitney brake lock. It's installed at the far left side of
the foot well and works well. We also use wheel chocks when "camping",
because I wouldn't trust it to hold over night (wouldn't want to be
awakened by having our bedroom roll into the woods or some SOB). The brake
lock works real well as an e-brake to hold the coach 'til we get the chocks
set. I know the lock would be unnecessary if we'd just fix the oem e-brake,
but IMHO, those are of such a poor design to be unworthy of the expense and
effort.

A couple cautionary notes;

1) Since the brake lock is released by your applying more pressure (pushing
the brake pedal) than it is holding back from when you set it, be carefull
when/if using it after pulling a long grade. Heat build-up from under the
coach causes the system to build a little pressure after you set the brake
lock and shut down. Thus, you might not be able to generate enough pressure
with your foot to get it to release. It happened to us and we were stuck in
a rest area for nearly an hour until the lines cooled enough to relieve the
extra pressure.

2) Be sure to release the lock (or regular e-brake) before you level. The
rear suspension geometry requires the wheels to be free to roll when
raising or lowering the coach. If in doubt, try this: a) chock the front
wheels, b)release the brake lock (or the working oem e-brake if that's what
you have), c) raise both sides to the top, d) lock the brakes, e) let all
the air out of one side and then f) release the brake. You'll note a sudden
drop on the side you let the air out of.

Strange Home page

They do not want you to look at their products without your life history.
Not my kind of page. A little pushy for me.

I am interested in your install.
