M&G brake system
Gardner, I have the M&G on my 01 suburban. I feel it works great
and fairly easy to install.

M&G brake system
The quick-connect is on the accessory circuit. If it failed open, the
air would bleed down to no less than the pressure-protection valve's pre-set limit, protecting the air supply to the front and rear air brake circuits (the red and green pointers are for the two air-brake system tanks, not the accessory system). Ditto for an air-bag failure, protected. - Jeff Miller in Holland, MI --- In WanderlodgeForum@yahoogroups.com, "Leroy Eckert" > > Hi folks: > I don't have a dog in this hunt and do not have a plumbing diagram of my bus air system. Now you got me wondering. I pull a trailer with electric brakes. My bus was factory fitted with a quick disconnect in roadside bay #3 , to be used for blowing up the tires. The pilot air gauge has two pointers, red and green, indicating redundant systems. Dumb question? If the quick disconnect in bay #3 failed would I lose all air to the brakes or is there a check valve somewhere that would prevent the event? If not, I may consider changing the quick disconnect to an manual shutoff valve. > > Thanks for your input. > > Leroy Eckert > 1990 WB40 > Niceville, FL > > > > > > > ----- Original Message ----- > From: smquandt > To: WanderlodgeForum@yahoogroups.com > Sent: Monday, August 21, 2006 2:28 PM > Subject: [WanderlodgeForum] Re: M&G brake system > > > I used a SMI silent partner on a PT-40/Honda CRV combination, and > like it.

M&G brake system
The M&G systems I've seen installed are tapped into the pressure output
of the drive-axle R-12 Brake relay valve, which is unsafe and illegal per FMVSS-121. I did meet a man who claimed that the damage to the front of his Wanderlodge was due to a severed air-line from his coach to the toad reducing his braking effectiveness without notice, causing him to rear- end another coach. The drive axle on these coaches is responsible for roughly 70% of your braking. To install it correctly you would need to install a Trailer Protection Valve / circuit like big trucks have. Get a non-invasive system. Although I had been a fan of proportional systems in the past, in reality the only thing that is really useful IMO is a towed-vehicle braking system that will apply the towed-vehicle brakes in a panic-stop or abrupt stop. Causing them to brake the combination during long grades and other stops risks wheel lockup or damage to the brakes, and isn't necessary. I've gotten to prefer a good system which will apply towed-vehicle brakes only when needed, and a system that is not invasive to the dinghy nor the coach is IMO a huge advantage. - Jeff Miller in Holland, MI --- In WanderlodgeForum@yahoogroups.com, "Gardner Yeaw" wrote: > > Has anyone used the M&G toad braking system?

Jeff,
Properly adjusted, SMI does exaclty as you describe, hard to panic stops only.

M&G brake system
Thanks to all for your responses.
I tend to agree that taping into the main brake system is a scary thing. I wondered about the legality, which was also brought up. I believe the brakes on my 78FC33 would likley handle my 1995 Jeep cherokee sport under normal stopping conditions without a problem. I will look into the SMI system as I still have time to make up my mind. All I really want is a safe dependable system that will assist in emergencies and stop the toad in a breakaway situation.

M&G brake system
Gardner,
I guess I'm just a few weeks ahead of you. I plan to tow my '93 Toyota. For supplemental braking, I'm considering the M&G as well as the SMI system <http://www.smibrake.com/index.html>. On the AllAboutRVing list, a member there suggested the VIP- Tow> systems. Clickon <http://www.viprv.com/index2.html> and look for the comparison chart. I like the M&G system because it uses the air brake system of the coach to control the toad brakes. That seems like a very straightforward choice. I like the SMI system because it uses the normal vacuum assist brakes in the tow vehicle and appears to put less stress on the toad braking system. The VIP-Tow> Personally, I'm interested in a system that doesn't need to be (partially) removed to drive the automobile. I haven't made my decision yet ... but it will be soon.

M&G brake system
Pete,
I ordered the SMI system tonight. I am hesitant to tamper with the air brake system and the SMI seems to do what I need. It ain't cheap, but spread out over a few years it isn't that bad. I can install it myself, and that saves a bit of change right there. I also ordered a Blue Ox tow bar. I may re-name my BB 'The Flying Dollar' P.S. I know with boats, it is considered bad luck to rename it, does that superstition exist with the RV crowd as well?

M&G brake system
FWIW
I have had the SMI Silent partner system in use for about 4 years. Adjustable, nothing to hook up except the break-away cable, feedback in coach, does not interfear with use of car, nothing to take out/put in, wireless comunication (I did have to use the external antena on my 45 ft coach) Have not had a single problem since install. I was going to go with the M&G but... No feed back to coach when car brakes are on, and in the end I found out it would not fit my PT Crusier toad anyway. BTW, Spartan (my chassis) now makes an add on tank/valve system just for this purpose.

M&G brake system
Gardner,
The more I study the issue, the more I'm leaning toward the SMI. I'm also reluctant to mess with the air brake system. Hopefully, I'll be able to install the SMI myself ... but working under the hood of a modern car isn't a thrilling adventure to me. Since I'll also have to install an oil pump for the transmission (so I can tow four down), I may try to find a mechanic to do both at the same time. Don't know if that will generate any savings... or not. (The only reason I've delayed setting up my car, etc. is that we're in the process of preparing our house for sale. As my dear wife says, "Finally, we have the house looking great ... then we sell it..." <sigh>) Pete Masterson aeonix1@...
