Dan,
Has your combination valve been replaced? If so do you know the part
number or source?

Thanks
Jim

> Hi Ron--a few thoughts. The unit we installed in Dan's coach was a Fenco
M1730 from Autozone. Although his brakes seem to work great, they also
worked great (before failure) with whatever was on there before. Dan may
want to pipe in whether they are as good now as originally. One issue with
recommending this for you is that you have 80mm front calipers which could
result in a volume problem for this M/C. But as you say for $16 (including
tax) it may be worth a try. Another thing to watch is the bleeding of the
unit. Dan, Jeff and I were surprised how much you have to bleed the M/C
itself. We had to do it on the coach which was fine, but it took a lot of
recirculating pushes of the pedal before we hooked up the lines. I have a
suspicion that some folks may have issues just because of inadequate
bleeding of the M/C itself.

No, I have not touched it. Jim K. has them if you need one.

G'day,

Ken Henderson has a series of annotated photographs on the Photo Site which
show how he removed the 130 psi feature to the rear brakes before the fronts
got pressure. He noted that his was "pretty cruddy" when he took it apart.

If you like you can start on the picture below and follow what he did step
by step.

According to the pictures the cost was negligible.
