Type of Roadmaster Brakemaster for Fleetwood Southwind Gas Motorhome
I purchased a Roadmaster Brakemaster 9060 supplemental braking system new I the box from a private party, thinking it should work fine on my 1999 Fleetwood Southwind 35S (Ford F53 gas) motorhome to stop my 2000 Jeep Grand Cherokee Laredo.
When I read the box further, however, it mentioned the possibility of "air over hydraulic" brakes.... I can recall that my coach makes a whirring noise when i step on the brake pedal before starting it. I was concerned that I may have bought the wrong Roadmaster brake kit. I always thought my gas coach had hydraulic brakes and that diesel pushers had air brakes. I have not heard of "air over hydraulic" before.
Can anyone advise me if they've successfully installed the Roadmaster 9060 system on their Fleetwood Southwind or similar Gas Motorhome? Moreover, id like to know what "air over hydraulic" brakes are, so i know if I have them. I always thought air brakes made the air release sound and hydraulics were "silent". Maybe i just need some education here. Id appreciate any feedback, so i know whether i have to look for a different braking system than the one just bought or just go ahead and install the compressor and components for the 9060 I already bought.
Thanks, and Happy Trails...
