jsut to add one more vote, I consider them to be minimum safey equipment.  When I bought my coach it was from the east coast and did not have jakes. I hd soe white knucke incidents going down even some farily gently but long hills here in so cal.  My tranny automatically upshifts when RPM reaches 2300, so unless I was really gonig slow enough, say 25 or 30 down the grapvine, I'd be using a lot of brakes on the descent, and even then it might be iffy if I could kee it slow enough.  39000 lbs on good bearings picks up speed frighteningly quickly.

So thats a hearty yes vote.

If looking for used units, the 71 series and 92 series are the same.  You just have to make sure you get the valve bridges for the 92 also, since they have to be used with the Jakes.  As to 6 cylinders, you can also buy 8 cylinder Jakes and just take one of the slave units off and plug the hole.  Good Luck, TomC

Hey Chris,

We live in the western mountains of NC.  After bringing our MC5A back from IL without Jakes...the KY and TN mountains made a believer out of me....I bought a used set and had them installed.

If you were to ask me if I would trade them for the money they cost and the dollars invested for the installation my answer would be an emphatic "NO"!

Would I travel our mountains again without them...or even the rolling country of the foothills around here?
Again, NO. 

They might not be quite as effective on a two cycle engine as on a four cycle...that's for the experts to determine...but for me and my wife it has reduced the pucker factor greatly.

Do anything within your power to stack the safety in your favor!

Hi guy!

I have Jake on my 8-71 but he don't work. I have not a manual of maintenance and, if I understood, there is a switch  (electrical) on the dash (off-low-hi) who activate the Jake. Why the Jake don't work? Electrical problem, switch, where I can see the switch on the motor? Do you have a link (internet) that I could see the system and searching the problem...(sorry for my poor english)

http://www.jakebrake.com/products/

try this web site for information.  also maybe the coach info site and i'm sure some others have some hints.

Don't worry about poor English.  You should hear my French.  Haven't had a lesson since 5th grade and that was a long, long time ago.  actually, my English isn't that great either.

hope this helps.

DD's won't run without the blower, so you won't need a Jake anyway.

I agree with everyone else.
I just made a 10,000 mile trip in a 05 Eagle/8v71/4 speed without them. I had to cross the Grapevine twice as well as I-40 from Texas to California, Needles, Bakersfield. I really had to re-think to the old days when we did not have them. I made it ok but Jakes would have made the trip much easier.

OKAY! thats it!!!  I'm a believer.  Where is the best place to start to gather the parts, or does is come in a kit?  I have to go through the Canadian Rockies next month.  I drove that way last summer and cooked my brakes a couple times.

Thom, I'm glad you're convinced! I'm also a firm believer in them and wouldn't have a bus w/o them now. Besides what's been said here, I also use mine in "non-hilly" terrain to slow the coach, like when coming into those small towns on a two-lane highway or even coming off an on-ramp. With the automatic, it'll come down through the gears to help decelerate and sometimes I just have to touch the service brakes for the last few feet. My big GMC muffler quiets them to a dull sound that's not too obtrusive.

Here's some "bus-friendly" places to look for the kits:
http://www.hbindustries.us/jake_brakes.htm
http://www.bernhardbus.com/jake.htm (link is currently "dead", but check back soon...  it was a great site for Jakes info and sales)
and I just found this from Google: http://www.gsnet.com/inventory/PartsAccessories/TruckPartsAccessories/default.asp?Page=4&Records=25

HTH,
Brian "blllaaahhhhtttttt blllaaahhhhtttttt" Brown

p.s. that was my best Jake Brake sound
