So, as soon as Manny gets me a 1-ton kit, I'll be upgrading the front end
of our '75 coach. It occurred to me that I'll then have a set of OEM
calipers and rotors left over. Is it possible/reasonable to mount these in the rear
in place of the center set of drum brakes?? If yes, is it difficult? Any pictures??

thanks,
Karen

You can use the rotor and caliper , we have the caliper stand and the
small spacer.

Jim,

Karen will also have to modify the parking brake cable system will she not?

Karen,
When we did the series of brake tests here with different systems, we
were finding that the units that had a drum in the rear and disc on
the intermediate started fading on the drum after couple hard stops
and few times the rear dragged as the front disc on the big rotors of
Harrison unit lifted the rear end to the max.
We saw less of that using the disc disc units.
Since we are almost getting to where we are going to be supplying a
good mechanical parking system, we should drop the idea of using drums
in the rear for parking brake and go all caliper with disc.
The maintenance of the all disc is so simple that our guys like doing
a maintenance check on my coach before my trips.
They refuse to give me green light on the engine as they know I'll mess it up.

Thanks Jim. I'm guessing using the OEM front disks on the rear should
be similar to the Eldorado junkyard conversion. Unfortunately, all the
links I've seen on how to do that are broken :-(

I've seen vague mention of using a proportioning valve between
the middle and rear wheels when converting only the middles to disk brakes.
Would that help with the rear drum fade? I'd really like to leverage
the parts I already have if that's a viable solution.

I agree disk brakes are so much better. I've started to really hate
drum brakes as they're a PITA to work on, and need constant attention.
I doubt the rear drums alone would be enough to hold as a parking brake
since it's not great even with 4 rear drums. I was thinking line locks,
but maybe there's a better way coming along.

thanks,
Karen

Karen,
Here are some links on how and what parts can be used if you wanted to
use Cadillac parts.

http://gmcmotorhomeinfo.com/brakes.html#CAD

The second link is the replacement for the pictures that were
referenced on Gene's site.

http://www.gmcmhphotos.com/photos/showgallery.php?cat=3119

Jim K also sells a very good, very complete disk brake conversion kit
that works well if you don't want to spend the time to round up the
parts.

Thanks John! That's one of the links I really wanted to see, but the reference on
Gene's site is broken.

So here's a really dumb question: what do you do for bearings/hubs in all
these retrofits? I can't figure it out from any of the descriptions I've seen.
There are pictures of rotors, and then pictures of completed assemblies, but
nothing in between.

One of the complete kits would be great, but the moment, I have a lot more time than money.

thanks,
Karen

Karen,
Your point is well taken re the combination valve.
In this case it might be a good idea to use our Disc/Disc combination valve.
All our kits come with the valves as you need to know when you have a
failer of the system.

Karen,
You remove the brake drums and install the re-drilled rotors on the
hubs as shown in the pictures. You can get re-drilled rotors from Jim
K.

Karen,

Double Trouble has:

P-30 Master Cylinder

ATE DOT 4 Brake Fluid

Sensitized booster from Jim B with two vacuum ports / check valves

Auxiliary vacuum pump mounted to the top of the radiator frame

Stainless steel brake line kit

Brass combination valve from Jim B in the drivers wheel well

Braided stainless steel hoses to all calipers / wheel cylinders

Caddy calipers / Performance Friction Carbon Metallic pads / OEM disks on
the front axles

Caddy caliper / Performance Friction Carbon Metallic pads / Caddy disks on
the middle axles

OEM drums on the rear axles
Note: I have two new drums, new Carbon Metallic shoes, and a new
spring kit which I will install next trip to the USA.

When Dan Gregg drove Double Trouble he was REALLY impressed with the way it
stopped.

Personally I reckon this is as good as it gets WITHOUT installing the
reaction arm system.

One could make the argument that installing disk brakes on the rear would
help brake fade but then you have to deal with the problem of not having a
mechanical parking brake and locking up the rear wheels under hard braking.

Rob M.

Hi Karen,
You might want to review the two section powerpoint presentation given at the International rally in Patterson, LA recently. The two sections are labeled as Drum brake improvements and Disc brake improvements. Some of the data may assist you in making a decision on which combination to choose.

I will never forget the day I drove Rob's coach. I could not believe how it stopped. It was like riding in a car and touching the brakes. I thought my drum rears worked really good but there was no comparison. That day I began thinking how I could come up with discs on the rear. I wanted all 4 because I hate working on drum brakes. When we got to Jim K's shop, he almost insisted that we also install the reaction arm. We did. I will never regret our decision. Life is so much better during our travels because I never worry about braking again. We also did the one ton frontend. If I could only have done one, the reaction arm setup would be the one.
So, for people that use their coach a lot, start thinking about how you can make it stop better.

Albert,

I must apologize; I forgot about the data you provided in your presentation
at Patterson!

I would like to revise the final sentence of my previous message regarding
this subject:

FROM:

Personally I reckon this is as good as it gets WITHOUT installing the
reaction arm system.

TO:

Personally I reckon this is as good as it gets WITHOUT installing the
reaction arm system with Kelsey - Hayes calipers on the rearmost axles.

Thanks Rob. Is the combination valve a replacement for the OEM one, or
in addition to it to separate the rear discs from the rear drums?

thanks,
Karen

Karen,
You can go look for a rear back plate from a Eldorado/Toronado or we
can quote you on the component parts.
Our component parts are usable should you go to the Reaction arm
system later. We credit you for the parts that will be replaced.

Karen,
You can go look for a rear back plate from a Eldorado/Toronado or we can quote you on the component parts.

Hi Guys;
The OEM Tornado / Eldorado backing plates ARE NOT of sufficient strength to prevent undue flex when used with a 12000 lb. motorhome. This excessive flex will result in excessive piston knockback and assure that you will have to go to a larger master cylinder even if you keep your rear drums.

Karen,

When a PO converted Double Trouble to Caddy disks on the rear he removed the
original combination valve completely.

When I replaced the rusty old brake lines with stainless steel they came
bent to include a combination valve.

Jim B and I discussed it and we decided to try installing a new brass
combination valve and see what happened as it would be easier than
re-bending the lines to eliminate it.

It works fine.

I do not know what size wheel cylinders Ken Frey put on when he removed the
rear disks and installed the drums so I could have an "Emergency" brake and
pass New Jersey inspection. I will find out the next time I'm back there
when I replace the rears with all new parts.

Regards,
Rob M.

Thanks Rob. Is the combination valve a replacement for the OEM one, or
in addition to it to separate the rear discs from the rear drums?

thanks,
Karen

Thanks Jim. Given that I'd have to get machining done on the Eldorado
plates, assuming I can even find them, I think your solution is
a better idea. I'd love a quote on the parts. I bet a lot of
other folks going to the 1-ton would consider this too, so maybe a
"move the front discs/rotors to the rear" kit would be useful.

thanks,
Karen

If anyone needs them, I've got one set of Eldorado backing plates
already remachined -- and used on my coach for 50,000 miles or so. I
replaced them with the more sturdy caliper mounts Terry Skinner used
to make. Then I replaced those, for larger (OEM) calipers, with some
of JimK's. I never had trouble with the backing plates, but the
caliper mounts are a more "elegant" solution.
