macattack Posted May 27, 2018 Share Posted May 27, 2018 (edited) my 96 mr688s seems to loose a bit of air when releasing the park brake. so i thought quick release valves, but on mine they look different. instead of one supply there are 2 supplys and 4 outs? per axle??? here are a couple of pics Edited May 27, 2018 by macattack Quote Link to comment Share on other sites More sharing options...
terry Posted May 27, 2018 Share Posted May 27, 2018 Them look like just a tee fitting, one for service and one for emergyncy maybe. terry 2 Quote Link to comment Share on other sites More sharing options...
fjh Posted May 27, 2018 Share Posted May 27, 2018 yup a tee you can use a quick release in both locations there if you cant find that! I highly doubt that will be a stocking item! Quote Link to comment Share on other sites More sharing options...
