Moorsman 0 Posted Wednesday at 07:56 PM Share Posted Wednesday at 07:56 PM Hi not sure if I have posted this in the correct forum if not please move. I look after an rb44 thas is used as a community snow plough and gritter. We have a problem in that although brakes are { fairly good for an rb 44} they are virtually non existent in reverse. Any tips? Regards kev Quote Link to post Share on other sites
steve b 343 Posted yesterday at 10:00 AM Share Posted yesterday at 10:00 AM Welcome to LR4x4 It sounds like an interesting truck , some general pic's would be nice . I'm not familiar with RB44 brake system specifics , again , some pic's of the layout on both axles might help to pinpoint your problem . The Dodge 50 was drums all round iirc ? A likely point to start is the rear load valve , is it free to operate ? cheers Steve b Quote Link to post Share on other sites
Bowie69 1,442 Posted yesterday at 10:09 AM Share Posted yesterday at 10:09 AM Drum brakes vehicles are really quite tricky in reverse, especially if both shoes are pointing in the same direction (i.e. twin leading shoe, twin cylinder setup), so I wouldn't be surprised if they were less effective. I'm currently daily driving a 1954 Morris Traveller, drums all round, and in reverse, I reckon you need three times the pedal pressure compared to going forward, and they are in good working order. You say you're are non-existent, to what extent? Quote Link to post Share on other sites
missingsid 137 Posted yesterday at 10:23 AM Share Posted yesterday at 10:23 AM Found this online re general braking performance, not helpful but made me laugh. If the RB was towing a 105 then it was probably ok - towing a 105 increases the braking efficiency of the RB by about 33%!!!! 105mm light gun presumably is a braked trailer.
