Installing M & G System

[Pat Z]

I just ordered this for my 2007 Avalanche and since there are no installers anywhere near me I am going to install it myself. I am pretty mechanically inclined but wanted to know if anyone has installed their own and if there is anything I should watch out for. I read where they want you to drive for 2 miles without using the front brakes to see if they are dragging. This is not going to be easy where I am. Any suggestions would be greatly appreciated.

At the time I lived about 45 minutes from M&G and opted to have them install the system on our Tacoma. In hindsight I think I could have easily installed the syste. I watched them install and they pointed out the few "gotchas". First, there is not enough clearance for the M&G cylinder. If you checked with them and they blessed the vehicle then you are ok. There is also the possibility of the "pushrod" being a little too long and partially applying the brakes. If you involved M&G during the purchase process you are probably ok. I think this problem is the result of someone buying a used unit for another vehicle. Each pushrod is calibrated for a specific vehicle.

In the 4+ years of use the only prolem I had was one of the air lines worked its way loose from the connector between the coach and vehicle. I had installed a tattle tail light which mounted on the front of the vehicle. When I apply the coach brakes the light will illuminate and I can see it in the rear view camera. You can purchase an air pressure switch from M&G or other sources and install it just before the M&G cylinder. When you apply the brakes the air pressure closes the switch and closes the electrical portion of the switch. A cheap LED side marker light worked well in my case and I ran 12v thru a fuse to the light.

I did check with them and ther are no fit issues, and it is a new unit that I bought from M&G. I Like the light idea I had one with my Brake Buddy. Perhaps I will cut into the brake light wire and install a light.

The brake light wire on the vehicle will not work, as the switch is on the pedal arm. The pedal does not move while using the M&G system.

Thanks after I posted it I realized that all it would tell me is that I activated the brake lights on the coach.
